— The respondents in these consolidated cases raised numerous issues regarding the constitutionality and applicability of Initiative 695 (1-695). The King County Superior Court held the initiative unconstitutional under article II, section 1(b); article II, section 19; and article II, section 37, of the Washington State Constitution. The State of Washington (State) and Intervenor $30 License Tab Initiative Campaign (the Campaign) appeal, contending that 1-695 is constitutional. We affirm the trial court for the following reasons.
(1) Article II, section 19 has two requirements in its two clauses: An act must have only one subject, and the subject of the act must be contained in the act’s title. The single subject rule of article II, section 19 is intended to prevent legislators, whether the people or the Legislature, from having to vote for a law that they do not favor in order to obtain a law which they do. 1-695 contains two subjects: (1) limiting license tab fees to $30 and (2) requiring voter approval of all future state and local tax increases. These two subjects are contained in both the title and the body of 1-695. 1-695 is therefore unconstitutional in its entirety.
(2) The second clause of article II, section 19 requires that the subject of a measure appear in the title. The purpose of *192this requirement is to notify those voting on the measure of its contents. I-695’s voter approval provision, section 2, applies to “taxes.” I-695’s express definition of this term establishes that “tax” does not mean “tax” as the term is commonly understood. Instead, “tax” as used in 1-695 has a broader meaning, including fees and charges which are not traditionally considered to be taxes. The title therefore fails to provide notice that I-695’s voter approval provision does not apply only to taxes as that term is commonly understood. Accordingly, section 2 of 1-695 is unconstitutional under the second clause of article II, section 19.
(3) Article II, section 1 concerns the legislative power in this state. Article II, section 1(a) and section 1(b) provide for the initiative and referendum powers, which are the people’s legislative powers. The referendum power of the people has two forms. The people can petition for referendum of legislation that the Legislature has passed. To do so, four percent of the voters must sign a petition. Alternatively, the Legislature may refer a measure to the people. Section 2 of 1-695 requires voter approval of all future tax legislation passed by the Legislature, but does not require a petition of the voters as to the specific piece of legislation, nor referral by the Legislature. Section 2 therefore establishes a referendum procedure not allowed under the state constitution and accordingly violates article II, section 1(b).
(4) Article II, section 37 prohibits enactment of legislation that revises or amends other acts without setting them forth at full length. The purposes of this provision are to avoid confusion, ambiguity and uncertainty in the law that would occur if the law existed in separate and disconnected legislative provisions, and to disclose the new law’s impact on existing laws. Section 2 of 1-695 violates this constitutional provision because it amends a statute already providing for voter approval of a port district’s industrial improvement assessment district without setting forth the existing act and showing how it is amended. Neither the existing statute nor the new enactment, 1-695, discloses the full law respecting such voter approval.
*193FACTS
In November 1999, the voters of Washington passed 1-695 by a 56.16 percent vote. Laws of 2000, ch. 1 (effective Jan. 1, 2000). The ballot title of 1-695 is “Shall voter approval be required for any tax increase, license tab fees be $30 per year for motor vehicles, and existing vehicle taxes be repealed.”1 State of Washington Voters Pamphlet, General Election (Nov. 2,1999). Section 1 of 1-695 sets motor vehicle license tab fees at $30. Laws of 2000, ch. 1, § 1(1). Section 2 provides that “[a]ny tax increase imposed by the state shall require voter approval.” Id. § 2(1). “Tax” is defined and “includes, but is not necessarily limited to, sales and use taxes, property taxes, business and occupation taxes, excise taxes, fuel taxes, impact fees, license fees, permit fees, and any monetary charge by government.” Id. § 2(2). “Tax” does not include “[h]igher education tuition” and “[c]ivil and criminal fines and other charges collected in cases of restitution or violation of law or contract.” Id. § 2(3). A “ ‘tax increase’ includes, but is not necessarily limited to, a new tax, a monetary increase in an existing tax, a tax rate increase, an expansion in the legal definition of a tax base, and an extension of an expiring tax.” Id. § 2(4). “State” is defined as including, “but is not necessarily limited to, the state itself and all its departments and agencies, any city, county, special district, and other political subdivision or governmental instrumentality of or within the state.” Id. § 2(5). The voter approval provision does not apply to “any specific emergency measure authorized by vote of two-thirds (2/3) of the members of each house of the legislature and expiring not later than twelve (12) months from the effective date of the emergency act.” Id. § 2(6). The provisions of section 2 of 1-695 are additional to and do not replace, the provisions of Initiative 601. Id. § 2(7).
Section 3 of 1-695 repeals 44 statutes. Id. § 3.1-695 states *194these are statutes which “impose taxes and fees on vehicles [,]” id., but some of the repealed statutes allocate funds to specific programs such as public transportation. 1-695 is to be liberally construed, id. § 4, and contains a severability provision, id. § 5.
Sections 1 and 3 of 1-695 repealed the motor vehicle excise tax (MVET), which many perceived as an unfair tax. Initially the MVET was a tax on vehicles, in lieu of a property tax, of 1.5 percent of the fair market value of the vehicle. Laws of 1937, ch. 228. In 1999, the MVET was 2.2 percent, and the value of vehicles was not determined according to fair market value, but rather was tied to the manufacturer’s base suggested retail price and the age of the vehicle. RCW 82.44.020; RCW 82.44.041(3)(b). MVET revenues were allocated to specific programs, such as public transportation, criminal justice, fire protection, and public health.
Prior to 1-695, most vehicle owners also paid a two dollar clean air excise tax. RCW 82.44.020(3), .110(3). Annual license fee statutes set license fees at under $30 for many vehicles. RCW 46.16.060(1). Most vehicle owners paid a one dollar license plate fee, RCW 46.16.650, and a 10 cent fee for highway studies, RCW 46.16.061. Owners of travel trailers and campers paid an excise tax of 1.1 percent. RCW 82.50.400, .410. Owners of campers and travel trailers also paid a clean air tax of two dollars and twenty-five cents under RCW 82.50.405. All of these statutes were repealed by 1-695.
1-695 did not repeal county and certain municipality annual license fees of up to $15 for most motor vehicles registered in their jurisdiction. RCW 82.80.020(1). Municipalities may impose a special excise tax of up to .725 percent of the value of motor vehicles owned by municipal residents. RCW 35.58.273; RCW 82.44.150. The second of these statutes was repealed by 1-695—among other things, it allocated revenues collected under RCW 35.58.273—but the other two were not. Certain cities and counties are authorized to impose an additional excise tax of up to .8 percent to provide for a high capacity transportation sys*195tem. RCW 81.104.160(1). This statute was not repealed by 1-695. Further, a three dollar license filing fee, RCW 46.01.140(4)(a), and a three dollar subagent fee, where applicable, RCW 46.01.140(5), were not repealed.
Thus, while repealing many statutes imposing vehicle taxes and fees, the .725 percent local vehicle excise tax, the .8 percent local transit excise tax, the $3 filing fee, the $3 subagent fee, and the $15 local vehicle license fee were not repealed by 1-695.
In the voters pamphlet for the November 1999 election, the proponents of the measure explained that section 2 of 1-695, the voter approval provision, was included to prevent imposition of other taxes that would replace lost MVET revenues.
Shortly after the voters adopted 1-695, the seven suits in this consolidated case were filed.2 In Amalgamated Transit Union Local 587 v. State, individual union members and Amalgamated Transit Union Local 587 (Amalgamated Transit) alleged that 1-695 violates the single-subject and subject-in-title requirements of article II, section 19, that 1-695, section 2 provides for an automatic referendum on all future tax and fee increases in violation of article II, section l(b)’s requirements that any referendum petition must have the signatures of four percent of the voters and that measures providing for the support of government and its public institutions are not subject to referendum, and that 1-695 violates article II, section 37, which requires the text of any acts amended or revised by a new enactment be set out in the new act. Amalgamated Transit sought a declaratory judgment that 1-695 violates the state constitution in *196its entirety and a permanent injunction against enforcement of any of the provisions of 1-695.
In Vashon-Maury Island Community Council v. State, Vashon Island Community Council (Vashon Island) alleged the same violations of article II, section 1(b) (concerning referenda) and article II, section 37 (setting forth amended or revised acts), but as to article II, section 19, alleged only that 1-695 violates the single-subject requirement. Vashon-Maury sought injunctive and declaratory relief.
In City of Bainbridge Island v. State, cities Bainbridge Island and Bremerton alleged that 1-695, section 2, violated article II, section l(b)’s four percent voter signature requirement, article II, section 19’s single-subject and subject-in-title requirements, and article II, section 37 (setting forth amended or revised acts). They also alleged that section 2 violates article VII, section 1 and article II, section 22 because it restricts the Legislature’s constitutional power to enact laws by majority vote; that section 2 violates article I, section 23 because it will impair contracts between the cities and their bondholders; and that section 2 violates article XXIII because it attempts to amend the constitution. The cities of Bainbridge Island, Bremerton, and Lakewood (Cities) asserted that charges made by cities for goods and proprietary services are not subject to the voter approval requirements of section 2 of 1-695 because they are not taxes within the meaning of1-695. This interpretive issue is the only part of the complaint which Lakewood joined in. The Cities sought declaratory and injunctive relief.
In Puget Sound Clean Air Agency v. State, plaintiff Puget Sound Clean Air Agency (Clean Air Agency) is responsible under state and federal law for air quality regulation and management in the region comprised of King, Pierce, Snohomish, and Kitsap Counties. The Clean Air Agency sought a declaratory judgment that section 2 of 1-695 does not prohibit the agency from recovering full reimbursement for certain operating permit program costs; that 1-695 violates the single-subject rule of article II, section 19; that section 2 violates article II, section 1 and article II, section 22 (improper amendment of initiative and referendum *197procedures); that 1-695 improperly repealed statutes in violation of article II, section 37; that 1-695 violates article XXIII (amendment of constitution); that 1-695 improperly restricts municipal taxing authority in violation of article XI, section 12; and also sought a declaration as to the application and effect of the voter approval requirement for any charges and fees subject to 1-695.
In Tacoma Water v. State, Tacoma Water (a division of Tacoma’s Department of Public Utilities), Covington Water District, Lakehaven Utility District, Seattle Public Utilities (a Seattle city department), and individual E.E. (Ted) Coates (an individual voter paying rates and taxes) sought a declaratory judgment that the voter approval requirements of section 2 of 1-695 do not apply to water rates or other utility charges (including charges for goods, services, or benefits provided in exchange for monetary or other consideration), to local improvement assessments, to connection or capacity charges, or to intergovernmental and intragovernmental payments and charges. They also sought a declaratory judgment that 1-695 violates article II, sections 1, 21, and 22 (referendum procedures and procedures for enactment of laws); article II, section 19’s requirements of a single subject and the subject in the title; article II, section 37’s requirement that amended or revised acts be set forth in full; article VII, section l’s prohibition against surrendering, suspending or contracting away taxing power; article VIII, section 7’s prohibition against unlawful gifts of public funds (insofar as 1-695 would limit charges to less than fair market value); article XI, section 12 (local taxing authority); and article XXIII (procedures for amending the constitution).
In Port of Whitman County v. State, the Ports of Whitman County, Tacoma, Skagit County, Seattle, Longview, Kennewick, Friday Harbor, and Bellingham (Port Districts) sought a declaratory judgment that 1-695 does not apply to rates, tariffs, fees, rents, assessments, local improvement district and industrial development district assessments, and other charges imposed by port districts in carrying out their functions, including, but not limited to, the operation *198of harbor and marina improvements, rail and motor vehicle transfer facilities, water transfer and terminal facilities, airports and terminal facilities, industrial development facilities, trade centers, and related commercial facilities. They asserted that these charges do not fall within the meaning of the term “tax” in section 2 of 1-695. These parties did not challenge the constitutionality of 1-695.
In Public Utility District No. 1 of Snohomish County v. State, Public Utility District No. 1 of Snohomish County (Snohomish PUD) sought a declaratory judgment that section 2 of 1-695 does not apply to the establishment and collection of rates and charges for electric energy and water; wastewater collection, treatment and disposal; and for other services, facilities, and commodities sold, furnished or supplied by public utility districts in a proprietary capacity; that section 2 does not apply to other monetary charges by public utility districts which are not commonly understood to be taxes; and that section 2 does not apply to the levy of special assessments by public utility districts. Snohomish PUD also sought a permanent injunction preventing enforcement of section 2 as to these items.
The Amalgamated Transit and Vashon-Maury cases were consolidated at trial, and all others were linked. The $30 License Tab Initiative Campaign (the Campaign) was a defendant in Port of Whitman County v. State and intervened in all other cases except Puget Sound Clean Air Agency v. State.
On March 6, 2000, King County Superior Court Judge Alsdorf heard cross-motions for summary judgment, and issued a written decision March 14, 2000, granting summary judgment in favor of respondents. The court held that 1-695 violates the state constitution because (1) section 2 unconstitutionally mandates universal referenda in violation of article II, section l(b)’s requirement that four percent of the registered voters sign a petition for referendum of an act of the Legislature; (2) section 2 unconstitutionally mandates universal referenda on laws and acts necessary for the support of state government and its existing institutions in violation of article II, section 1(b); *199(3) Section 2 is unconstitutional because it seeks to amend the state constitution without compliance with article XXIII; (4) the initiative as a whole is unconstitutional because it covers more than one subject in violation of article II, section 19; (5) sections 2 and 3 violate article II, section 19 because not all subjects in their text are identified in the title; and (6) the initiative as a whole violates article II, section 37 because it is not a complete act, and it fails to set forth the text of other laws which it amends and fails to explain how those amendments are worded or are to be implemented.
The court struck down the initiative in its entirety. The court also issued an injunction against the State and any of its subdivisions from taking any action to implement or enforce section 2, but declined to issue an injunction as to the remainder of 1-695 because it would be disruptive to enjoin the operation or enforcement of sections 1 and 3.
The State and the Campaign appealed directly to this court, which granted review. The League of Women Voters of Washington, the Association of Washington Public Hospital Districts, the Association of Washington Housing Authorities, and individuals Conley “Gene” E. Kincheloe, Josie L. Schindler, and the Washington Coalition of Citizens with Disabilities (Coalition) were granted leave to file briefs as amici curiae.
After the trial court’s decision, on March 31, 2000, the Legislature enacted Senate Bill 6865 (Laws of 2000, 1st Spec. Sess., ch. 1) repealing the MVET and setting vehicle license tab fees at $30.
ANALYSIS
I. The Campaign’s Motion to Dismiss
The Campaign includes in its opening brief a motion to dismiss all the respondents and all the cases on various grounds. “A party may include in a brief only a motion which, if granted, would preclude hearing the case on the merits.” RAP 17.4(d). If the Campaign’s motion is granted in whole or in part, it would preclude a hearing on the merits as to one or more of the respondents. Accordingly, we address the motion.
*2001. Mootness
The Campaign first contends that the Amalgamated Transit respondents and Vashon-Maury, and their cases, should be dismissed on the grounds of mootness. The Campaign says these respondents challenged section 1 of 1-695, reducing vehicle license tab fees to $30, and all of their asserted injuries arose from the reduction of the MVET in sections 1 and 3 of 1-695. The Campaign says these respondents have no standing or particularized interest apart from any other member of the public, citing Greater Harbor 2000 v. City of Seattle, 132 Wn.2d 267, 281-82, 937 P.2d 1082 (1997). As the Campaign points out, the Legislature recently enacted a $30 license tab fee provision which became effective March 31, 2000. See Laws of 2000, 1st Spec. Sess., ch. 1 (S.B. 6865, retroactive to Jan. 1, 2000). The State, however, does not agree that the legislation renders the major issues moot.
Respondent Amalgamated Transit maintains that even a technically moot case may be reviewed where it presents issues of continuing and substantial public interest. Philadelphia II v. Gregoire, 128 Wn.2d 707, 712, 911 P.2d 389 (1996); Sorenson v. City of Bellingham, 80 Wn.2d 547, 558, 496 P.2d 512 (1972).3 We are not convinced that claims based on section 1 of 1-695, the $30 license tab fee section, come within this exception. Section 1 of 1-695 involves a limited subject and there is no serious dispute that in general an initiative can repeal, impose, or amend a specific tax.
However, for purposes of the single subject and subject-in-title requirements of article II, section 19, we must consider 1-695 as a whole in order to determine its validity. Also, section 1 of 1-695 is relevant to the article II, section 37 claims. Therefore, for the article II, section 19 claims and *201the article II, section 37 claims, the Legislature’s enactment does not moot the issues. Amalgamated Transit argued to the trial court that 1-695 violates article II, section 19 and article II, section 37, and is entitled to argue these claims before this court. Vashon-Maury joined in Amalgamated Transit’s arguments.
Also, contrary to the Campaign’s claim that Amalgamated Transit challenged only section 1 of 1-695, Amalgamated Transit argued to the trial court that its members directly depend upon monetary charges levied by state and local governments for their jobs and salaries and under section 2 of 1-695 these levies are subject to an unconstitutional vote. The Legislature’s new enactment does not affect section 2 of 1-695. As noted, Vashon-Maury joined in Amalgamated Transit’s arguments. Vashon-Maury says it is a representative organization whose members’ livelihoods and property values depend upon ferry and bus services as well as police protection provided through monetary charges levied by state and local government, which are subject to unconstitutional vote under section 2.
In its reply brief, the Campaign also says that the Legislature’s recently enacted supplemental budget accommodated the people’s initiative decision by restoring some of the funding which repeal of the MVET removed from various programs such as public transportation, police and fire protection, and provided for raising the local sales tax for public transportation with voter approval. The Campaign does not say that this legislation renders the rest of the issues in these cases moot, and clearly it does not. The Legislature’s action providing some relief to local government cannot validate an unconstitutional measure. Moreover, section 2 of1-695 remains, and will continue to bar any new taxes or tax increases without voter approval—thus the initiative has continuing impact aside from repeal of the MVET and the Legislature’s restoration of some funding.
These cases are not moot as a result of the Legislature’s enactment of legislation repealing the MVET and imposition of a $30 license tab fee.
*2022. Failure to Cross-Appeal
The Campaign also moves to dismiss the Cities, the Tacoma Water respondents, the Snohomish PUD, and the Port Districts on the ground that the trial court entered a declaratory judgment adverse to their interests and none has appealed. The Campaign reasons these respondents had argued for a narrow reading of “tax” in 1-695, but the trial court construed the term broadly. These respondents’ failure to cross-appeal, the Campaign says, precludes consideration of their claims.
Failure to cross-appeal an issue generally precludes its review on appeal. See, e.g., Tellevik v. 31641 W. Rutherford St., 120 Wn.2d 68, 89, 838 P.2d 111, 845 P.2d 1325 (1992). However, “[a] successful litigant need not cross-appeal in order to urge any additional reasons in support of the judgment, even though rejected by the trial court, but no additional relief will be granted on appeal in the absence of a cross-appeal.” Peterson v. Hagan, 56 Wn.2d 48, 52, 351 P.2d 127 (1960); see City of Tacoma v. Taxpayers of Tacoma, 108 Wn.2d 679, 685, 743 P.2d 793 (1987). These respondents prevailed in the trial court, not as a result of a narrow construction of the term “tax,” but because of the trial court’s determination that 1-695 is unconstitutional in its entirety. Having obtained a favorable judgment, the fact that these respondents did not cross-appeal the trial court’s ruling on the meaning of the term “tax” in 1-695 is not a basis to dismiss them, nor does it bar them from challenging the trial court’s construction of the term as an alternative ground to affirm the judgment in their favor.
3. Standing and Justiciability
The Campaign also claims that all respondents lack standing and the cases are nonjusticiable, citing Walker v. Munro, 124 Wn.2d 402, 879 P.2d 920 (1994). When moving for summary judgment in the trial court, the Campaign did not raise any issue regarding the standing of the respondents to challenge the constitutionality of 1-695 under article II, sections 1(b), 19, and 37. The Campaign attempts to raise the standing issue for the first time on appeal. In *203the past, this court has held that the issues of standing and justiciability under the Uniform Declaratory Judgments Act, chapter 7.24 RCW, may be raised for the first time on appeal. Wash. Beauty Coll., Inc. v. Huse, 195 Wash. 160, 80 P.2d 403 (1938). However, the Campaign has not provided sufficient argument regarding standing. Its cite to Walker is virtually the whole of its “argument.” We will not consider the issue in the absence of adequate argument. See, e.g., State v. Wheaton, 121 Wn.2d 347, 850 P.2d 507 (1993); Kadoranian v. Bellingham Police Dep’t, 119 Wn.2d 178, 186-87, 829 P.2d 1061 (1992).
The same problem exists with regard to the claim that these actions are nonjusticiable. The Campaign attempts to raise this issue for the first time on appeal, but fails to provide more than conclusory statements and a single cite to Walker. We also note that under the Uniform Declaratory Judgments Act, the requirement of standing tends to overlap justiciability requirements. 15 Lewis H. Orland & Karl B. Tegland, Washington Practice: Trial Practice: Civil § 602, at 394 (5th ed. 1996). Thus the inadequacy of briefing respecting standing carries over to the nonjusticiability challenges. We decline to address the Campaign’s claim that none of the actions are justiciable.4
*204II. Constitutionality of 1-695
An exercise of the initiative power is an exercise of the reserved power of the people to legislate. State ex rel. Heavey v. Murphy, 138 Wn.2d 800, 808, 982 P.2d 611 (1999); Belas v. Kiga, 135 Wn.2d 913, 920, 959 P.2d 1037 (1998). In approving an initiative measure, the people exercise the same power of sovereignty as the Legislature does when enacting a statute. Wash. Fed’n of State Employees v. State, 127 Wn.2d 544, 556, 901 P.2d 1028 (1995). The fact that the legislative body has the power to achieve a particular result does not necessarily render its action constitutional; it must follow constitutional procedures. State ex rel. Living Servs., Inc. v. Thompson, 95 Wn.2d 753, 755, 630 P.2d 925 (1981). The people acting in their legislative capacity are subject to constitutional mandates. State ex rel. Heavey, 138 Wn.2d at 808; Gerberding v. Munro, 134 Wn.2d 188, 196, 949 P.2d 1366 (1998); Culliton v. Chase, 174 Wash. 363, 373-74, 25 P.2d 81 (1933). The initiative process cannot be used to amend the constitution. Gerberding, 134 Wn.2d at 210 n.11.
*205A statute enacted through the initiative process is, as are other statutes, presumed to be constitutional. Brower v. State, 137 Wn.2d 44, 52, 969 P.2d 42 (1998); Gerberding, 134 Wn.2d at 196; State ex rel. O’Connell v. Meyers, 51 Wn.2d 454, 458, 319 P.2d 828 (1957). A party challenging the statute’s constitutionality bears the heavy burden of establishing its unconstitutionality beyond a reasonable doubt. State ex rel. Heavey, 138 Wn.2d at 808; Gerberding, 134 Wn.2d at 196. This standard is met if argument and research show that there is no reasonable doubt that the statute violates the constitution. Belas, 135 Wn.2d at 920; Island County v. State, 135 Wn.2d 141, 147, 955 P.2d 377 (1998).
Rules of statutory construction apply to initiatives. Seeber v. Pub. Disclosure Comm’n, 96 Wn.2d 135, 139, 634 P.2d 303 (1981); Gibson v. Dep’t of Licensing, 54 Wn. App. 188, 192, 773 P.2d 110 (1989). Thus, in determining the meaning of a statute enacted through the initiative process, the court’s purpose is to ascertain the collective intent of the voters who, acting in their legislative capacity, enacted the measure. Dep’t of Revenue v. Hoppe, 82 Wn.2d 549, 552, 512 P.2d 1094 (1973). Where the voters’ intent is clearly expressed in the statute, the court is not required to look further. Senate Republican Campaign Comm. v. Pub. Disclosure Comm’n, 133 Wn.2d 229, 242, 943 P.2d 1358 (1997); City of Tacoma v. State, 117 Wn.2d 348, 356, 816 P.2d 7 (1991); see Biggs v. Vail, 119 Wn.2d 129, 134, 830 P.2d 350 (1992) (if statutory meaning is clear from plain and unambiguous language, that meaning must be accepted by the court). In determining intent from the language of the statute, the court focuses on the language as the average informed voter voting on the initiative would read it. State v. Brown, 139 Wn.2d 20, 28, 983 P.2d 608 (1999); Senate Republican Campaign Comm., 133 Wn.2d at 243. Where the language of an initiative enactment is “plain, unambiguous, and well understood according to its natural and ordinary sense and meaning, the enactment is not subject to judicial interpretation.” State v. Thorne, 129 Wn.2d 736, 762-63, 921 P.2d 514 (1996). However, if there is ambiguity *206in the enactment, the court may examine the statements in the voters pamphlet in order to determine the voters’ intent. Thorne, 129 Wn.2d at 763; see Lynch v. Dep’t of Labor & Indus., 19 Wn.2d 802, 812-13, 145 P.2d 265 (1944); see Biggs, 119 Wn.2d at 134 (if there is ambiguity, extrinsic aids, such as legislative history, may be used to determine legislative intent).
“[I]t is not the prerogative nor the function of the judiciary to substitute what they may deem to be their better judgment for that of the electorate in enacting initiatives . . . unless the errors in judgment clearly contravene state or federal constitutional provisions.” Fritz v. Gorton, 83 Wn.2d 275, 287, 517 P.2d 911 (1974). Nor is it the province of the courts to declare laws passed in violation of the constitution valid based upon considerations of public policy. State ex rel. Wash. Toll Bridge Auth. v. Yelle, 32 Wn.2d 13, 24-25, 200 P.2d 467 (1948).
A grant of summary judgment is reviewed de novo, and the reviewing court engages in the same inquiry as the trial court. Trimble v. Wash. State Univ., 140 Wn.2d 88, 92, 993 P.2d 259 (2000). Summary judgment is proper where there are no genuine issues of material fact and the moving party is entitled to judgment as a matter of law. CR 56(c). Construction of a statute is a question of law which is reviewed de novo. State v. Ammons, 136 Wn.2d 453, 456, 963 P.2d 812 (1998).
1. Article II, section 19
Article II, section 19 of the Washington State Constitution provides that “[n]o bill shall embrace more than one subject, and that shall be expressed in the title.” Article II, section 19 is to be liberally construed in favor of the legislation. Wash. Fed’n, 127 Wn.2d at 555; State Fin. Comm. v. O’Brien, 105 Wn.2d 78, 80, 711 P.2d 993 (1986); Wash. State Sch. Dirs. Ass’n v. Dep’t of Labor & Indus., 82 Wn.2d 367, 371, 510 P.2d 818 (1973). Article II, section 19 applies to initiatives. Wash. Fed’n of State Employees v. State, 127 Wn.2d 544, 551-53, 901 P.2d 1028 (1995); Fritz v. Gorton, 83 Wn.2d 275, 328-42, 315-16 (holding of court by *207six justices in dissenting and concurring opinions).
There are two distinct prohibitions in article II, section 19. See Patrice v. Murphy, 136 Wn.2d 845, 852, 966 P.2d 1271 (1998). The first is that no bill shall embrace more than one subject. The purpose of this prohibition is to prevent logrolling or pushing legislation through by attaching it to other legislation. Power, Inc. v. Huntley, 39 Wn.2d 191, 198, 235 P.2d 173 (1951); see also State v. Broadaway, 133 Wn.2d 118, 124, 942 P.2d 363 (1997); State v. Thorne, 129 Wn.2d 736, 757, 921 P.2d 514 (1996); Flanders v. Morris, 88 Wn.2d 183,187, 558 P.2d 769 (1977). The second prohibition is that no bill shall have a subject which is not expressed in its title. The purpose of this prohibition is to notify members of the Legislature and the public of the subject matter of the measure. Power, 39 Wn.2d at 198; see also Broadaway, 133 Wn.2d at 124; Thorne, 129 Wn.2d at 757; Flanders, 88 Wn.2d at 187.
a. The single-subject rule.
In determining whether 1-695 contains more than one subject in violation of article II, section 19, we begin with the title of the measure. “The Legislature may, if it chooses, adopt a very broad and comprehensive title in a bill, in which case great liberality will be indulged to hold that any subject reasonably germane to such title may be embraced within the body of the bill.” DeCano v. State, 7 Wn.2d 613, 627, 110 P.2d 627 (1941); accord Wash. Fed’n, 127 Wn.2d at 555-56; Wash. Toll Bridge Auth. v. State, 49 Wn.2d 520, 523, 304 P.2d 676 (1956); State ex rel. Scofield v. Easterday, 182 Wash. 209, 212, 46 P.2d 1052 (1935); Percival v. Cowychee & Wide Hollow Irrig. Dist., 15 Wash. 480, 482, 46 P. 1035 (1896). There is no violation of article II, section 19 even if a general subject contains several incidental subjects or subdivisions. Wash. Fed’n, 127 Wn.2d at 556; State v. Grisby, 97 Wn.2d 493, 498, 647 P.2d 6 (1982).
A general title is one which is broad rather than narrow. Wash. Fed’n, 127 Wn.2d at 555; O’Brien, 105 Wn.2d at 90; Gruen v. State Tax Comm’n, 35 Wn.2d 1, 22, 211 P.2d 651 (1949), overruled on other grounds by State ex rel. State Fin. *208Comm’n v. Martin, 62 Wn.2d 645, 384 P.2d 833 (1963). It may be comprehensive and generic rather than specific. Olympic Motors, Inc. v. McCroskey, 15 Wn.2d 665, 672, 132 P.2d 355 (1942); DeCano, 7 Wn.2d at 627. Examples of general titles are: “An Act Relating to violence prevention.” In re Boot, 130 Wn.2d 553, 566, 925 P.2d 964, 971 (1996). “An Act Relating to the amendment or repeal of statutes superseded by court rule.” State v. Howard, 106 Wn.2d 39, 45, 722 P.2d 783 (1985). “Shall campaign contributions be limited; public funding of state and local campaigns be prohibited; and campaign related activities be restricted?” Wash. Fed’n, 127 Wn.2d at 555, 557. “[A]n act relating to capital projects . . . .” O’Brien, 105 Wn.2d at 79-80. “An Act Relating to tort actions . . . .” Scott v. Cascade Structures, 100 Wn.2d 537, 546, 673 P.2d 179 (1983). “An Act Relating to Community Colleges . . . .” Wash. Educ. Ass’n v. State, 97 Wn.2d 899, 906-07, 652 P.2d 1347 (1982). “An Act Relating to the death penalty . . . .” Grisby, 97 Wn.2d at 498. “An Act Relating to industrial insurance . . . .” Wash. State Sch. Dirs. Ass’n v. Dep’t of Labor & Indus., 82 Wn.2d 367, 371, 510 P.2d 818 (1973). “An Act to provide an Insurance Code for the State of Washington; to regulate insurance companies and the insurance business; to provide for an Insurance Commissioner; to establish the office of State Fire Marshall; to provide penalties for the violation of the provisions of this act. . . .” Kueckelhan v. Fed. Old Line Ins. Co., 69 Wn.2d 392, 402, 418 P.2d 443 (1966). “An Act Relating to revenue and taxation; increasing the motor vehicle fuel tax, the use fuel tax and motor license fees, gross weight fees, fees in lieu of gross weight fees, seating capacity fees, providing for the distribution of said revenue; establishing an urban aid account in the motor vehicle fund; establishing a Puget Sound reserve account; providing for the use of the urban aid account. . . ; authorizing investment of the Puget Sound reserve account. . . .” State ex rel. Wash. Toll Bridge Auth. v. Yelle, 61 Wn.2d 28, 31-33, 377 P.2d 466 (1962). “An Act authorizing the incorporation of mutual savings banks, defining their powers and duties, and prescribing penalties for violations hereof.” In re Peterson’s Estate, 182 Wash. 29, 33, 45 P.2d 45 (1935).
*209In assessing whether a title is general, it is not necessary that the title contain a general statement of the subject of an act; “[a] few well-chosen words, suggestive of the general subject stated, is all that is necessary.” State ex rel. Scofield, 182 Wash. at 212; accord Wash. Fed’n, 127 Wn.2d at 554; In re Peterson’s Estate, 182 Wash. at 33.
Where a general title is used, all that is required is rational unity between the general subject and the incidental subjects. Wash. Fed’n, 127 Wn.2d at 556; Grisby, 97 Wn.2d at 498; Scott, 100 Wn.2d at 545; Kueckelhan, 69 Wn.2d at 403; Gruen, 35 Wn.2d at 22. This principle has been explained as follows:
“Under the true rule of construction, the scope of the general title should be held to embrace any provision of the act, directly or indirectly related to the subject expressed in the title and having a natural connection thereto, and not foreign thereto. Or, the rule may be stated as follows: Where the title of a legislative act expresses a general subject or purpose which is single, all matters which are naturally and reasonably connected with it, and all measures which will, or may, facilitate the accomplishment of the purpose so stated, are properly included in the act and are germane to its title.”
Kueckelhan, 69 Wn.2d at 403 (quoting Gruen, 35 Wn.2d at 22). The requirement of rational unity has also been explained as follows:
“[A constitutional single-subject prohibition] does not by restricting the contents of an ‘act’ to one subject, contemplate a metaphysical singleness of idea or thing, but rather that there must be some rational unity between the matters embraced in the act, the unity being found in the general purpose of the act and the practical problems of efficient administration. It is hardly necessary to suggest that matters which ordinarily would not be thought to have any common features or characteristics might, for purposes of legislative treatment, be grouped together and treated as one subject. For purposes of *210legislation, ‘subjects’ are not absolute existences to be discovered by some sort of a priori reasoning, but are the result of classification for convenience of treatment and for greater effectiveness in attaining the general purpose of the particular legislative act.. ..”
State ex rel. Wash. Toll Bridge Auth. v. Yelle, 61 Wn.2d at 33 (quoting State ex rel. Test v. Steinwedel, 203 Ind. 457, 467, 180 N.E. 865, 868 (1932) (discussing Indiana constitutional provision)).
A restrictive title, in contrast to a general title, “ ‘is one where a particular part or branch of a subject is carved out and selected as the subject of the legislation.’ ” Broadaway, 133 Wn.2d at 127 (quoting Gruen, 35 Wn.2d at 23). A restrictive title will not be regarded as liberally as a general title, “and provisions not fairly within it will not be given force.” Broadaway, 133 Wn.2d at 127; see Thorne, 129 Wn.2d at 758; State ex rel. Wash. Toll Bridge Auth. v. Yelle, 32 Wn.2d 13, 26, 200 P.2d 467 (1948).
A restrictive title is “narrow,” as opposed to broad. See [Gruen] at 22; Washington Fed’n, 127 Wn.2d at 555; State Fin. Comm, v. O’Brien, 105 Wn.2d 78, 80, 711 P.2d 993 (1986). It is of specific rather than generic import. Olympic Motors, Inc. v. McCroskey, 15 Wn.2d 665, 672, 132 P.2d 355, 150 A.L.R. 1306 (1942); DeCano v. State, 7 Wn.2d 613, 627, 110 P.2d 627 (1941). A restrictive title expressly limits the scope of the act to that expressed in the title. See . . . Daviscourt v. Peistrup, 40 Wn. App. 433, 439-440, 698 P.2d 1093 (1985).
Broadaway, 133 Wn.2d at 127. Examples of restrictive titles are:
“Shall criminals who are convicted of‘most serious offenses’ on three occasions be sentenced to life in prison without parole?” State v. Thorne, 129 Wn.2d 736, 757, 921 P.2d 514 (1995). “An act relating to the acquisition of property by public agencies . . . .” Daviscourt v. Peistrup, 40 Wn. App. 433, 437, 698 P.2d 1093 (1985). . . . “An act relating to local improvements in cities and towns . . . .” Cory v. Nethery, 19 Wn.2d 326, 329-31, 142 P.2d 488 (1943). “An act relating to the rights and disabilities of aliens with respect to land . . . .” DeCano v. State, 7 *211Wn.2d 613, 623, 110 P.2d 627 (1941). “An act relating to the venue of civil actions in justice courts.” National Ass’n of Creditors v. Brown, 147 Wash. 1, 7, 264 P. 1005 (1928). “An act creating and providing for the enforcement of liens for labor and material.” Armour & Co. v. Western Constr. Co., 36 Wash. 529, 537, 78 P 1106 (1905). “An act giving workmen’s compensation benefits to persons engaged in hazardous and extra-hazardous occupations in charitable institutions.” Swedish Hosp. v. Department of Labor & Indus., 26 Wn.2d 819, 830-31, 176 P.2d 429 (1947).
Broadaway, 133 Wn.2d at 127 n.2. In Broadaway, the title of Initiative 159 was held restrictive: “An act relating to increasing penalties for armed crime . . . .” Broadaway, 133 Wn.2d at 126. In Thorne, the title of Initiative 593 was also held restrictive: “Shall criminals who are convicted of‘most serious offenses’ on three occasions be sentenced to life in prison without parole?” Thorne, 129 Wn.2d at 757.
Cases where violations of the single-subject requirement have been found have varied. For example, an act providing criminal penalties for dognapping and the recovery of attorney fees in some civil replevin actions violated article II, section 19. Barde v. State, 90 Wn.2d 470, 584 P.2d 390 (1978). An act which included a civil rights provision and regulation of cemeteries violated article II, section 19. Price v. Evergreen Cemetery Co., 57 Wn.2d 352, 357 P.2d 702 (1960). In general, violations of the single-subject rule are more readily found where a restrictive title is used. E.g., Potter v. Whatcom County, 138 Wash. 571, 576, 245 P. 11 (1926) (restrictive title “An Act Relating to townships and amending. . . .” held not broad enough to embrace provision placing bridges costing more than $300 under the sole jurisdiction and control of the county); Nat’l Ass’n of Creditors v. Brown, 147 Wash. 1, 7, 264 P. 1005 (1928) (restrictive title “An Act relating to the venue of civil actions in justice courts” not broad enough to encompass provision that if an action was prosecuted contrary to the venue requirements, no jurisdiction over the defendant was obtained).
Where an initiative to the people is concerned, as is the case here, the relevant title for the article. II, section 19 *212inquiry is the ballot title, because not all initiatives have legislative titles; because it is the ballot title with which the voters are faced in the voting booth; and because it is the ballot title which can be appealed before an election and which thereafter appears on petitions and the ballot. Wash. Fed’n, 127 Wn.2d at 555; see Thorne, 129 Wn.2d at 757; RCW 29.79.070.
The ballot title of 1-695 is “Shall voter approval be required for any tax increase, license tab fees be $30 per year for motor vehicles, and existing vehicle taxes be repealed?”
The State and the Campaign contend that 1-695 has a general title, and the single subject of the measure is limiting taxation. They urge that all of the provisions of 1-695 are rationally related to the general subject of limiting taxation. However, in making this argument, they want the court to consider the Voters Pamphlet and “legislative history” as evidence of rational unity.5 In deciding whether a measure contains a single subject, however, the constitutional inquiry is founded on the question whether a measure is drafted in such a way that those voting on it may be required to vote for something of which the voter disapproves in order to obtain approval of an unrelated law. Wash. Fed’n, 127 Wn.2d at 552; Wash. Toll Bridge Auth. v. State, 49 Wn.2d 520, 525, 304 P.2d 676 (1956). Thus, regardless of what is in the Voters Pamphlet or the history of the initiative, the rational relationship inquiry centers on what is in the measure itself, i.e., whether the measure contains unrelated laws.
*213Amalgamated Transit6 argues that 1-695 does not concern one subject, limiting taxes. Amalgamated Transit contends that from the plain language of the initiative the voters knew that as a whole the measure concerned more than just taxes. This is because the title and text expressly distinguish between “taxes” and “fees.” Amalgamated Transit argues that the difference between the two is of constitutional dimension, with a tax being “a levy made for the purpose of raising revenue for a general governmental purpose” and a fee being enacted “principally as an integral part of the regulation of an activity and to cover the cost of regulation.” Franks & Son, Inc. v. State, 136 Wn.2d 737, 750, 966 P.2d 1232 (1998). Amalgamated Transit urges that voters are aware of this fundamental legal distinction. Because 1-695 concerns both fees and taxes, it does not contain a single subject, “limiting taxation.” Further, this respondent notes, 1-695 had the effect of increasing some annual vehicle renewal fees, and this raising of government revenue is not within the subject of “limiting taxes.”
Amalgamated Transit further argues that the ballot title of 1-695 contains three propositions, all of them restrictive. Amalgamated Transit urges that the ballot title carves out part of the subject of taxes, asking whether voter approval should be required; asks whether the license tab fee should be only $30; and carves out another facet of the general subject of taxes, i.e., whether to repeal existing vehicle taxes. Amalgamated Transit says that three restrictive title parts do not equal one general title.
The Tacoma Water respondents maintain that 1-695 has at least two subjects: reducing license tab fees and voter approval of taxes. They urge that because these two subjects were tied together, the voters were not free to vote for one of the proposals and against the other if they wished. As do the appellants, these respondents also focus on history of the measure, and how the election campaign was conducted, to argue that limiting taxes is not the subject of *2141-695. They say that the stated purpose of the measure was to prevent replacement of MVET revenues by imposition of other taxes, and that given this purpose, there is no rational unity because the measure requires all new taxes and tax increases to be voted upon, not just those that might replace the MVET revenues. However, whether or not there is one subject in 1-695 must be determined from the measure itself. 1-695 does not, anywhere within its text or title, say that only taxes which could replace the MVET revenues are subject to voter approval. The measure on its face is broader than the Tacoma Water respondents urge is its subject.
The Tacoma Water respondents argue that there is no relationship at all between the subjects in 1-695 in regard to Tacoma Water’s water rates and charges. Amicus Curiae Public Hospital Districts similarly argues that there is no rational unity between repeal of the MVET and the voter approval provision if applied to all government fees and charges, including its own charges because, it points out, it never received MVET revenue.
The Clean Air Agency offers another argument. It says that I-695’s voter approval provision does not apply just to traditional taxes, but also applies to all fees or monetary charges by government. Therefore, because more than “taxes” are subject to voter approval, the subject matter of the initiative is not “limiting taxation,” contrary to the State’s argument. (As the Clean Air Agency acknowledges, though, the State argues for a traditional definition of “tax.”)7 This respondent also maintains that there are two subjects in 1-695: repeal of the MVET and government process, in particular the way in which revenue generating laws can be made in the future.
Amicus Curiae League of Women Voters of Washington urges that I-695’s title is not a general title because all it does is mirror the specific provisions of the initiative rather than identifying general topics on a theme in which the *215provisions fall. Amicus League of Women Voters cites State ex rel. Wash. Toll Bridge Auth. v. Yelle, 32 Wn.2d 13, 200 P.2d 467 (1948), a case where the court determined the title was restrictive, not general. As Amicus League of Women Voters points out, there the title of the original act related to toll bridges and tunnels, and the title to an amending act referred to toll bridges and the powers and duties of the toll bridge authority, and also referred to ferry connections. The court concluded that the title of the amendatory act was not a general title concerning a transportation system, but was instead a restrictive title referring to “the specific subject of toll bridges and, at most, highway and ferry connections and approaches thereto.” Id. at 27. The court reasoned that the body of the act contained more than one subject, toll bridges and ferries, and that its dual subjects did not “comprehend Q any such broad appellation as ‘transportation system.’ ” Id.
Amicus League of Women Voters says that, similarly, here the phrase “limiting taxation” is not found anywhere in the title or body of 1-695, and urges that the voter approval provision does not limit taxes, but instead specifies a method of approving tax increases. These are not the same, the League urges, because specifying a method for approval is a broad procedural provision which directs how future tax increases will occur, not whether they will occur.8
However, as appellants argue, it is not necessary for the words “limiting taxation” to appear in the title or body of the act in order for I-695’s title to be general. In Fritz v. Gorton, 83 Wn.2d 275, 290-91, 517 P.2d 911 (1974), the court identified the “generic subject” of 1-276 as “openness in government,” though those words never appeared in the title. Cf. Thorne, 129 Wn.2d at 758 (though the title was held to be restrictive, the subject matter was found to be “persistent offenders” even where those words did not *216appear in the title); but see State ex rel. Wash. Toll Bridge Auth. v. Yelle, 32 Wn.2d at 27 (noting that act did not mention “transportation system”). The League distinguishes Fritz on the basis that there the lengthy, detailed title would disclose the topic “openness in government,” while here, it contends, the average voter would not understand “limiting taxation” to be the subject of 1-695.
We conclude that this single-subject issue is controlled by Wash. Toll Bridge Auth. v. State, 49 Wn.2d 520, 304 P.2d 676 (1956), relied upon by the Cities, Amalgamated Transit, and Amicus League of Women Voters. In that case, a new act was passed which provided procedures for establishing and financing toll roads, and also provided specifically for a toll road from Tacoma to Everett. The title included both of these purposes. The court held this was a general title and adequately expressed the subjects in the act. Id. at 523. However, the court held that the two were not germane to each other because one purpose of the act was to provide for a specific road which was subject to accomplishment and not continuing in nature, while the second purpose did not pertain to any specific road but was continuing in effect. The act was unconstitutional because it contained two subjects in both the title and the body. Wash. Toll Bridge Auth., 49 Wn.2d at 524. A similar analysis was applied in Power. There, the court noted that article II, section 19 prohibits the passage of an act relating to different subjects expressed in its title, in which case the whole act is void. Power, 39 Wn.2d at 200. The title and the act both contained two unrelated subjects, appropriations and a corporate income tax, and it was accordingly held unconstitutional in its entirety.9
Here, while the title of 1-695 seems in part restrictive, i.e., the part which says that “[s]hall... license tab fees be $30 per year for motor vehicles [,]” the balance of the title *217broadens its scope, similarly to the title in Wash. Toll Bridge Auth. v. State. We conclude that 1-695 has a general title. However, there is no rational unity between the subjects of 1-695. Similar to the act in Wash. Toll Bridge Auth. v. State, 1-695 also has two purposes: to specifically set license tab fees at $30 and to provide a continuing method of approving all future tax increases. Further, neither subject is necessary to implement the other. 1-695 violates the single-subject requirement of article II, section 19 because both its title and the body of the act include two subjects: repeal of the MVET and a voter approval requirement for taxes.
b. The subject-in-title rule of article II, section 19.
The second requirement of article II, section 19 is that the subject of an act must be expressed in its title. The purpose of this requirement is, as noted, provision of notice to legislators and the public of the contents of the measure. This court has recognized the particular importance of this requirement in the context of an initiative, noting that often voters will not reach the text of a measure or the explanatory statement, but may instead cast their votes based upon the ballot title. Wash. Fed’n, 127 Wn.2d at 553-54.
The title of an act complies with article II, section 19 if it gives notice which would lead to an inquiry into the body of the act or indicates the scope and purpose of the law to an inquiring mind. Wash. Fed’n, 127 Wn.2d at 555; YMCA v. State, 62 Wn.2d 504, 506, 383 P.2d 497 (1963); Treffry v. Taylor, 67 Wn.2d 487, 491, 408 P.2d 269 (1965). However, the title need not be an index to the contents, nor must it provide details of the measure. Wash. Fed’n, 127 Wn.2d at 555; Treffry, 67 Wn.2d at 491; Gruen, 35 Wn.2d at 22; Cory v. Nethery, 19 Wn.2d 326, 330, 142 P.2d 488 (1943); Petroleum Lease Props. Co. v. Huse, 195 Wash. 254, 260, 80 P.2d 774 (1938); State ex rel. Zent v. Nichols, 50 Wash. 508, 97 P. 728 (1908); State ex rel. Cole v. City of New Whatcom, 3 Wash. 7, 27 P. 1020 (1891).
The trial court held that the word “tax” in the ballot title of 1-695 does not provide the notice which article II, section 19 requires because it fails to inform of the scope of the *218measure. The trial court held that “tax” does not have its traditional meaning in the context of 1-695, and reasoned that because “tax” encompasses a broader range of fees and charges than are commonly referred to as taxes, use of the term “tax” in the title of 1-695 provides insufficient notice of what the contents of the measure might include. Therefore 1-695 is unconstitutional because it violates article II, section 19.
In order to evaluate this issue, the parties’ considerable arguments on the meaning of the term “tax” must be addressed. In brief, the trial court held that the term “tax” in 1-695 must be given a broad construction to include specific fees for commercial or proprietary products or services rendered or benefits received, fees, assessments other than taxes, and even utility charges by PUDs, rather than a narrower construction including “traditional taxes.” The State argues that the term “tax” should be construed to mean any compulsory charge for the support of government and to exclude amounts charged for specific goods or services, proprietary or commercial charges, and special assessments, such as local improvement districts (LID) assessments. The Snohomish PUD generally agrees with the State’s approach. The Campaign does not discuss the issue in its briefing to this court. Amalgamated Transit also does not address the issue, and accordingly neither does Vashon-Maury Island Community Council (since it adopts Amalgamated Transit’s argument on the issues). The Cities accept and argue on appeal the trial court’s construction, but only for purposes of arguing to uphold the trial court’s ruling that 1-695 violates article II, section 19. The Tacoma Water respondents argue that “tax” means a charge imposed on people, property, or transactions for the general funding of government without any required connection between the amount charged and the benefit received.
The meaning of the term “tax” is to be determined according to the intent of the voters. Dep’t of Revenue, 82 Wn.2d at 552. If this intent can be determined from the language of the initiative, the court’s inquiry ends there. Senate Republican Campaign Comm., 133 Wn.2d at 242. *219Section 2(1) of 1-695 provides that “[a]ny tax increase imposed by the state shall require voter approval.” Section 2(2), (3) and (4) provide:
(2) For the purposes of this section, “tax” includes, but is not necessarily limited to, sales and use taxes, property taxes, business and occupation taxes, excise taxes, fuel taxes, impact fees, license fees, permit fees, and any monetary charge by government.
(3) For the purposes of this section, “tax” does not include:
(a) Higher education tuition, and
(b) Civil and criminal fines and other charges collected in cases of restitution or violation of law or contract.
(4) For the purposes of this section, “tax increase” includes, but is not necessarily limited to, a new tax, a monetary increase of an existing tax, a tax rate increase, an expansion in the legal definition of a tax base, and an extension of an expiring tax.
Section 2(5) provides that “state” “includes, but is not necessarily limited to, the state itself and all its departments and agencies, any city, county, special district, and other political subdivision or governmental instrumentality of or within the state.”
Language in an initiative should be construed as the average informed voter voting on the initiative would read it. State v. Brown, 139 Wn.2d 20, 28, 983 P.2d 608 (1999). As a noun, the term “tax” has as its common meaning a “pecuniary charge imposed by legislative or other public authority upon persons or property for public purposes : a forced contribution of wealth to meet the public needs of a government.” Webster’s Third New International Dictionary 2345 (1986). These definitions probably accord with the average informed voter’s understanding of the term “tax,” and are consistent with the State’s argument that “tax” means a compulsory charge for the support of government. This definition is also consistent with legal definitions offered by the Port Districts and Snohomish PUD. “Tax” means “an enforced contribution of money, assessed or charged by authority of sovereign government for the benefit of the state or the legal taxing authorities *220[and it] is not a debt or contract in the ordinary sense, but it is an exaction in the strictest sense of the word.” State ex rel. City of Seattle v. Dep’t of Pub. Utils., 33 Wn.2d 896, 902, 207 P.2d 712 (1949). “Tax” is a “pecuniary burden laid upon individuals or property to support the government, and is a payment exacted by legislative authority. Essential characteristics of a tax are that it is not a voluntary payment or donation, but an enforced contribution, exacted pursuant to legislative authority.” Black’s Law Dictionary 1457 (6th ed. 1990). (Citation omitted.)
However, the language of 1-695 indicates that “tax” does not have its traditional meaning. 1-695 specifically defines the term “tax.” It would be unnecessary to define the term if it had its common meaning, and, if the term has its common meaning, the definition is superfluous. All language in a piece of legislation should be given effect, so that no provision is rendered superfluous. See City of Bellevue v. Lorang, 140 Wn.2d 19, 25, 992 P.2d 496 (2000); W. Petroleum Importers, Inc. v. Friedt, 127 Wn.2d 420, 428, 899 P.2d 792 (1995). Additionally, an enactment’s definition of a term prevails over a dictionary definition or common understanding of a term. In re F.D. Processing, Inc., 119 Wn.2d 452, 458, 832 P.2d 1303 (1992).
Moreover, under section 2(2) “tax” “includes, but is not necessarily limited to .. . [the list of charges], and any monetary charge by government.” (Emphasis added.) This language also suggests that the term “tax” has a broad meaning. Further, the term “any” in “any monetary charge” (emphasis added) means something other than “similar,” lending further weight to the argument that “tax” is defined expansively.
The meaning of language must also be determined from the enactment as a whole, with each provision read in relation to the other provisions. City of Seattle v. Dep’t of Labor & Indus., 136 Wn.2d 693, 698, 965 P.2d 619 (1998); Hubbard v. Dep’t of Labor & Indus., 140 Wn.2d 35, 43, 992 P.2d 1002 (2000). While the parties mainly focus on the term “any monetary charge” and the preceding list of *221charges in section 2(2) of 1-695, section 2(3)’s exclusions from the term “tax,” i.e., higher education tuition and civil and criminal fines and charges, indicate that “tax” must be given a broad construction. These excluded charges are not compulsory charges for the support of government, or, in the standard dictionary’s terms, a forced contribution of wealth to meet the public needs of government, and there would be no need for their exclusion if “tax” is given its ordinary traditional meaning. Nor are these items charges which the average informed voter would think are “taxes.” A broad construction of “tax” accords with the specific exclusions and avoids rendering them superfluous.
Further, the specific list of charges which are defined as taxes in subsection 2 includes “license fees.” The average informed voter would not conclude that the charge for a state nurse’s license, for example, is a “tax” in its traditional sense.
Some respondents and amici, however, rely on certain language in 1-695 for the proposition that a restrictive meaning of “tax” is intended. The initiative uses the word “imposed.” Section 2(1) says “[a]ny tax increase imposed by the state shall require voter approval.” (Emphasis added.) The Housing Authority says that its charges for rental housing units are not “imposed” on those choosing to rent a unit.
“Impose” has as its ordinary meaning “to make, frame, or apply (as a charge, tax, obligation, rule, penalty) as compulsory, obligatory, or enforceable .. .: LEVY. . . .” Webster’s Third New International Dictionary 1136 (1986). “Levy” means “to impose or collect (as a tax or tribute) by legal process or by authority : EXACT. . . .” Id. at 1301. These common definitions are broader than the Housing Authority suggests and do not limit the term “tax” to its common meaning.
The Snohomish PUD and the Port Districts point to the word “government” in the phrase “any monetary charge by government,” and argue that because the word “state” is used (and defined) elsewhere in the initiative, “govern*222ment” must have a different meaning from “state.” See Seeber v. Pub. Disclosure Comm’n, 96 Wn.2d 135, 139-40, 634 P.2d 303 (1981) (where certain language is used in one instance and different language in another, there is a difference in legislative intent). These respondents urge that “government” must pertain to governmental power rather than to proprietary power. Therefore, they reason, only charges of a governmental nature, rather than proprietary charges, are “taxes.” The argument is not persuasive. A charge by government is a charge by an entity. The word is used as a noun, not as an adjective.
We conclude from the plain language of 1-695 that “tax” does not have a traditional meaning, but instead has a broad meaning.
The State, the Tacoma Water respondents, and Snohomish PUD urge, however, that the term “any monetary charge by government” in section 2(2) is ambiguous, and therefore the court should resort to rules of statutory interpretation. However, even if one accepts the premise that the term is ambiguous, it does not follow that “tax” has its traditional meaning. These parties first argue that the rule of ejusdem generis applies, contending that the term should take its meanings from the specific taxes and fees preceding it. See City of Seattle, 136 Wn.2d at 699. They disagree, though, as to the result of applying the rule. In the State’s view, traditional taxes and fees like those listed fall within the meaning of “tax,” i.e., those in the nature of a governmental fee or tax, but all charges by government do not. Thus, the State urges that the term should be construed to mean a compulsory charge for the support of government. The Snohomish PUD’s approach is similar. Its view is that each of the eight listed charges is either a tax in the traditional sense or a regulatory fee that involves the exercise of governmental, not proprietary, power. It says that the eight charges are “compulsory exactions” by the state in the nature of taxes.
In the Tacoma Water respondents’ view, the eight enumerated items in section 2(2) are monetary charges by *223government that produce general revenue for the general fund, and they urge that the term “any monetary charge” must be similarly limited. These respondents say that the State’s definition is essentially meaningless, because virtually every government charge can be categorized as compulsory because you have to pay it if you wish to obey the law. They also want the court to reject the State’s proprietary-governmental distinction. They say that, for example, cities supplying some areas of a city with clean, disease-free drinking water do so in their governmental capacity to promote the general health and safety of the citizens, but where that problem does not exist, the cities act in a proprietary capacity. Under the State’s definition, these respondents say, water rates in the first situation are not taxes, while in the second they are.
The rule of ejusdem generis does not apply as any of the parties urge. It is clear that the list of eight charges on its face includes items that are not traditional taxes, such as license fees, impact fees, and permitting fees. Our inquiry here is whether, for purposes of the article II, section 19 subject-in-title rule, the term “tax” has a broader meaning than its commonly understood, traditional meaning. Some of the listed items, as well as the exclusions in section 2(3), plainly establish that section 2(2) is not limited to traditional “taxes,” and the rule of ejusdem generis does not lead to a different conclusion.
Several of the respondents urge that extrinsic indicators of the voters’ intent show that a broad meaning of “tax” was not intended. Assuming that, for the sake of the argument, ambiguity exists, looking to the Voters Pamphlet for evidence of the voters’ intent would be appropriate. The Snohomish PUD says that there is nothing in the Voters Pamphlet to indicate that there was any intent to apply the voter approval provision to utility rates, special assessments and other proprietary charges by PUDs. Instead, the intent expressed is that of an antitax measure. The Port Districts similarly say that there is no mention in the ballot title, the ballot summary, or the statements in the Voters *224Pamphlet of proprietary charges by a port district. They also urge that only conventional taxes are mentioned in the title and summary. The Tacoma Water respondents say that water rates and charges are not the type of monetary charge commonly understood to be a tax under Washington common law, and the voters did not intend to include such charges within the term “tax.”
The Port Districts and the Tacoma Water respondents say that the purpose of 1-695 was to repeal the MVET and prevent government entities from increasing taxes to make up for the loss. The Port Districts say they never received any MVET funds and have no reason to make such funds up. The Tacoma Water respondents also say they never received any MVET funds, and the term “tax” should be construed to encompass only charges that could replace those funds. Amicus Housing Authority makes a similar argument.
The Voters Pamphlet for the November 2, 1999, general election discloses that the purposes of1-695 are to eliminate “outrageously expensive” vehicle tabs and require voter approval for any other tax increase because “we knew politicians would try to raise other taxes.” Voters Pamphlet at 4. The rebuttal of the statement against the initiative explains that “[o]nce vehicle tabs were lowered to $30, we knew politicians would try to raise other taxes. 1-695 is carefully written and requires voter approval for tax increases, meaning politicians CAN’T impose property taxes on vehicles, a state income tax, or ANY tax without asking your permission first.” Voters Pamphlet at 4.
Two things are apparent from examining the Voters Pamphlet and 1-695. First, the stated purposes of preventing politicians from replacing MVET revenues by raising other “taxes” does not establish that only traditional taxes were contemplated. For example, a local transit authority might raise the cost of a bus pass to compensate for lost MVET funds allocated to public transportation. Second, to the extent that the Voters Pamphlet indicates that only tax measures which might replace the MVET funds would *225require approval, such intent is not reflected in 1-695. Nothing in 1-695 restricts the voter approval requirement based upon replacement of MVET revenues. Section 2 of 1-695 on its face is a broad tax limitation measure. Thus, even if there were ambiguity in the term “any monetary charge by government,” the Voters Pamphlet, when compared to 1-695 itself, cannot support the conclusion that “tax” is limited to its common meaning.
Many of the respondents and amici also argue, though, that if the term “tax” is defined to encompass any charge by government, absurd results ensue. If a statute is ambiguous, and therefore subject to judicial construction, a court must construe the statute to effectuate legislative intent, and in so doing “ ‘avoid a literal reading if it would result in . .. absurd . . . consequences.’ ” City of Seattle, 136 Wn.2d at 697-98 (quoting Whatcom County v. City of Bellingham, 128 Wn.2d 537, 546, 909 P.2d 1303 (1996)). However, because the language of the initiative itself sufficiently resolves the meaning of the term, there is no ambiguity to resolve and this rule does not apply. State v. Azpitarte, 140 Wn.2d 138, 142, 995 P.2d 31 (2000).
The State also argues that by giving the term “tax” a broad construction the trial court failed to apply the principle that a statute will be construed to preserve its constitutionality where possible. See State v. Crediford, 130 Wn.2d 747, 755, 927 P.2d 1129 (1996). The court’s broad interpretation was a key factor in the trial court’s decision that 1-695 is unconstitutional under article II, section 19. However, while legislation should be construed to preserve its constitutionality where possible, given the provisions of 1-695 we do not agree that the measure can be construed to apply only to “traditional” taxes, or that the voters intended a distinction between proprietary and governmental functions. A court should “not strain to interpret [a] statute as constitutional: a plain reading must make the interpretation reasonable.” Soundgarden v. Eikenberry, 123 Wn.2d 750, 757, 871 P.2d 1050 (1994).
We affirm the trial court’s holding that “tax” has a *226broader meaning than its common, traditional meaning and, given I-695’s exceedingly broad definition including “any monetary charge by government,” includes specific fees for commercial or proprietary products or services rendered or benefits received, fees, assessments other than taxes, and even utility charges by PUDs.
It follows that the trial court’s holding that 1-695 violates the subject-in-title rule of article II, section 19 must be affirmed. In DeCano v. State, 7 Wn.2d 613, 110 P.2d 627 (1941), this court addressed an amendatory act which was titled “An Act relating to the rights and disabilities of aliens with respect to land, and amending . . . .” Id. at 623. However, the body of the act specifically defined “alien” in a way “which brings within its purview a whole new class of persons who are not in fact aliens in common understanding . . . .” Id. at 624. The court applied the rule that “ ‘[w]ords in a title must be taken in their common and ordinary meanings, and the legislature cannot in the body of an act impose another or unusual meaning upon a term used in the title without disclosing such special meaning therein.’ ” Id. at 626 (quoting 59 C.J. 810). The court held that the act violated article II, section 19.
This court applied the same rule in Petroleum Lease Properties Co., 195 Wash. 254. There, the title of the act was “An Act providing for the regulation and supervision of the issuance and sale of securities to prevent fraud in the sale thereof, amending. . . .” Id. at 257. In the body of this amendatory act the term “securities” was defined to include oil or gas leases. The court said: “The title gives no notice that there is to be embodied in the amendment the regulation of any matter not embraced within the meaning of the word ‘security’ as that term is commonly understood and defined by standard dictionaries, as well as by the original securities act itself. That a gas or oil lease is not a ‘security’ as ordinarily understood, or as defined in the original act, is self-evident.” Id. at 258. See also Swedish Hosp. v. Dep’t of Labor & Indus., 26 Wn.2d 819, 822, 830, 832, 176 P.2d 429 (1947) (title “An Act giving workmen’s compensation ben*227efits to persons engaged in hazardous and extrahazardous occupations in charitable institutions” violated article II, section 19 because it did not give notice that provisions concerning nonprofit, organizations and institutions were encompassed within the act).
The court in DeCano distinguished State ex rel. Port of Seattle v. Department of Public Service, 1 Wn.2d 102, 95 P.2d 1007 (1939). There, in a comprehensive title the terms “storage warehouse and warehousemen” were used, which the court in DeCano said were broad enough to embrace all storage warehouses, including those operated by municipal corporations such as port districts. Moreover, the court noted in DeCano, the title used the phrase “defining the same” following those terms, which called attention to the fact that these terms were defined in the body of the statute. DeCano, 7 Wn.2d at 630.
As in DeCano and Petroleum Lease Properties, we affirm the trial court’s holding that 1-695 violates the subject-in-title rule of article II, section 19 on the basis that the ballot title of 1-695 states “[s]hall voter approval be required for any tax increase” without any indication in the title that “tax” has a meaning broader than its common meaning.10 Nothing about this ballot title gives any notice that would indicate to the voters that the contents of the initiative would include voter approval for charges other than taxes or suggest inquiry into the act be made to learn the broad meaning of “tax.”
The next question is whether, due to unconstitutionality under the subject-in-title clause of article II, section 19, 1-695 is unconstitutional in its entirety. A legislative act is not unconstitutional in its entirety unless invalid provisions are unseverable and it cannot be reasonably be believed that the legislative body would have passed *228one without the other, or unless elimination of the invalid part would render the remaining part useless to accomplish the legislative purposes. Gerberding v. Munro, 134 Wn.2d 188, 197, 949 P.2d 1366 (1998); State v. Crediford, 130 Wn.2d 747, 760, 927 P.2d 1129 (1996). A severability clause may provide the assurance that the legislative body would have enacted remaining sections even if others are found invalid. Gerberding, 134 Wn.2d at 197. However, a severability clause is not necessarily dispositive on the question of whether the legislative body would have enacted the remainder of the act. Leonard v. City of Spokane, 127 Wn.2d 194, 201, 897 P.2d 358 (1995). 1-695 has a severability clause.
In Petroleum Lease Properties, the court said that the act was unconstitutional so far as it attempted to bring oil and gas leases within the scope of the securities act. In DeCano, the court similarly held that so far as the act tried to bring within its scope individuals not falling within the commonly understood meaning of “alien,” it was unconstitutional. In Swedish Hospital, the court said it would presume the legislators knew that nonprofits were included in the body of the act, but it could not presume that the legislators would have enacted the measure without the invalid portion. Therefore, the act was invalidated in its entirety.
Here, we hold that section 2 of 1-695 is invalid under the subject-in-title clause of article II, section 19.
The trial court also ruled that section 3 of 1-695 contains subjects not identified in the ballot title. Where an act contains provisions not fairly encompassed within the title, such provisions are void. Power, 39 Wn.2d at 200. Although the title of 1-695 refers to “repeal of existing vehicle taxes,” some of the repealed statutes imposed no tax or fee but instead allocated proceeds of the license tab fees to police, fire and other purposes and established accounts and funds for deposit and withdrawal of these moneys.11 Repeal of *229these statutes, the trial court ruled, deprived named programs and government agencies of their present share of the funding, a result not identified in the ballot title. Other repealed statutes removed exemptions from motor vehicle taxes, and their repeal increased taxes.12 This increase, the trial court said, also was not disclosed in the title. Accordingly, the trial court held, repeal of these statutes was unconstitutional under article II, section 19.
The State argues, however, that the title need not provide the details contained within the measure; that these subjects are not separate subjects because the title gives notice that “existing vehicle taxes” are repealed and the average informed voter would not require further notice that such repeal would lead to a loss of revenue; and finally, that, where by statute the ballot title is limited in length, to invalidate the initiative on the basis that it does not provide sufficient detail would be contrary to the right of the people to legislate. In its reply brief, the State adds that the Voters Pamphlet provided adequate notice of these provisions, and the public therefore had sufficient notice.
Given I-695’s general title, section 3 falls within it. The title provides sufficient notice that the initiative repealed taxes, and thus, notice that decreased revenues and loss of funding would result. Removal of exemptions from a tax does not alter the tax itself. The small increase in some license fees as a result of repeal of the MVET is sufficiently related to the repeal to bring them within the general title. While section 2 of 1-695 violates the subject-in-title rule of article II, section 19, section 3 does not.
2. Article II, section 1(b)
The State and the Campaign contend the trial court erred in holding that section 2 of 1-695 violates article II, section l(b)’s requirement that four percent of the voters sign a referendum petition. They argue that under section 2 of *2301-695 any measure imposing increased taxes (as defined in 1-695) becomes conditional legislation subject to voter approval. Amalgamated Transit, the Cities, Tacoma Water, and the Clean Air Agency contend the trial court’s ruling is correct, arguing that section 2 establishes an unconstitutional referenda process.
The Seventh Amendment to the Washington State Constitution, adopted by the voters in 1912, established the initiative and referendum powers. The state constitution provides in part:
The legislative authority of the state of Washington shall be vested in the legislature . . . but the people reserve to themselves the power to propose bills, laws, and to enact or reject the same at the polls, independent of the legislature, and also reserve power, at their own option, to approve or reject at the polls any act, item, section, or part of any bill, act, or law passed by the legislature.
(a) Initiative: The first power reserved by the people is the initiative ....
(b) Referendum. The second power reserved by the people is the referendum, and it may be ordered on any act, bill, law, or any part thereof passed by the legislature .. . either by petition signed by the required percentage of the legal voters, or by the legislature as other bills are enacted .... The number of valid signatures of registered voters required on a petition for referendum of an act of the legislature or any part thereof, shall be equal to or exceeding four percent of the votes cast for the office of governor at the last gubernatorial election preceding the filing of the text of the referendum measure with the secretary of state.
Const, art. II, § 1. The filing of a referendum petition suspends the effectiveness of the statute until 30 days after the next general election, if the voters approve the statute; and a measure referred by the Legislature takes effect 30 days after the next general election if approved by the voters. Const, art. II, § 1(d).
Article II, section 1(b) defines the legislative, initiative and referendum powers of state government. Citizens for *231Financially Responsible Gov’t v. City of Spokane, 99 Wn.2d 339, 349, 662 P.2d 845 (1983).
1-695, section 2(1) provides that “[a]ny tax increase imposed by the state shall require voter approval.” The trial court reasoned that while section 1 of 1-695 enacted specific changes in the amount, structure and distribution of a particular tax, and is accordingly a proper legislative subject of an initiative measure (as is section 3), section 2 automatically suspends in the future every tax-related action of government until the voters approve or disapprove of the action. The court reasoned that section 2 is therefore universal, constitutes a presumptive veto, and establishes a referendum. Then, the court reasoned, as a universal referenda provision section 2 conflicts with article II, section l(b)’s requirement that a referendum petition must be signed by four percent of the registered voters. Section 2 mandates a vote even though there may be no public opposition or controversy over a particular tax-related action. The court then reasoned that it would require redrafting the measure in order to uphold it as to local taxing measures, and declined to engage in such redrafting.
We uphold the trial court’s ruling on the basis that section 2 establishes a referendum process applying to every piece of future tax legislation. Article II, section 1 begins by stating that the legislative power is vested in the Legislature, and then identifies the powers reserved to the people by the Seventh Amendment—the initiative and referendum powers. Article II, section 1(b) then describes how the reserved powers of the people are to be exercised. Where the people seek a referendum on legislation passed by the Legislature, article II, section 1(b) requires that four percent of the voters petition for referendum before a referendum election must be held. The other method by which a referendum election may be held is where the Legislature decides to refer a measure it has passed to the people for their vote.
Under section 2 of1-695 all state tax measures “passed by the legislature” are automatically subject to voter approval. Article II, section 1(b) states that the referendum power *232“may be ordered on any act, bill, law, or any part thereof passed by the legislature.” (Emphasis added.) Section 2 of 1-695 effectively authorizes mandatory referendum elections on all future tax legislation passed by the Legislature where the Legislature has not referred the legislation13 and where four percent of the registered voters have not signed petitions for referendum on the particular legislation passed by the Legislature. Under section 2 a tax measure passed by the Legislature is suspended until and unless the voters approve it, as is the case when the people petition for referendum. As did the trial court, we conclude that section 2 calls for universal referenda on all legislation which would impose increased taxes without regard to whether a particular piece of legislation would engender enough interest or opposition for four percent of the voters to petition for referendum.
Not only does section 2 fail to comply with the article II, section 1(b) procedures for referenda, it also was adopted in an improper way. The state constitution does not provide that the initiative power can be used to alter the method by which the referendum power is exercised. The people in exercising their reserved powers must conform to the constitution, just as the Legislature must do when enacting legislation. Here, exercise of the initiative power to enact section 2 has the effect of replacing the referendum petition process for any future state taxing legislation. The initiative process cannot be used to amend the constitution. Gerberding, 134 Wn.2d at 210 n.ll. Article XXIII sets forth the method by which the constitution may be amended and requires that amendments be proposed by the Legislature.
The State argues, though, that the trial court erred in characterizing the effect of section 2 of 1-695 as effecting a “permanent” suspension of future tax acts. See Clerk’s Papers (CP) at 836. The State points out 1-695 is a statute *233which cannot permanently bind the Legislature. After two years, the Legislature can repeal the act and, within two years, can by a two-thirds vote, amend it. Const, art. II, § 1(c). The State reasons that this constitutionally based deference does not amount to establishment of an unauthorized article II referendum.14
While 1-695 may not have “permanent” effect, depending upon future legislative action, that fact does not resolve the question whether section 2 constitutes a referendum. Every measure voted upon by the people and passed, whether by initiative or referendum, is subject to the same constitutional strictures; all are subject to amendment by a two-thirds vote during two years after enactment and subject to repeal or amendment after that time. Moreover, this court has rejected the premise that substantive amendments contained in an appropriations bill were not subject to article II, section 37 because budget bills have only a two-year duration. Flanders v. Morris, 88 Wn.2d 183, 190, 558 P.2d 769 (1977). Constitutional provisions apply even if a measure does not have “permanent” effect.
The primary argument of the State and the Campaign is that the trial court’s analysis is in error because 1-695 is not an automatic referendum provision, but instead establishes a state policy that voter approval must be sought as a condition to the effectiveness of any new tax or tax increase. Appellants argue that under section 2 no direct legislation is required for future tax increases; instead tax increases imposed by the Legislature must receive the permission of the voters before taking effect. They maintain that such “conditional legislation” is valid.
As noted, the people act in a legislative capacity when enacting an initiative. Belas v. Kiga, 135 Wn.2d 913, 920, 959 P.2d 1037 (1998). Enacting conditional legislation is a legislative power. See Brower v. State, 137 Wn.2d 44, 56, 969 P.2d 42 (1998). Generally, the question of the validity of *234conditional legislation arises when it is claimed that the Legislature has unconstitutionally delegated its legislative authority. Under article II, section 1, “ [t]he legislative authority of the State is vested in the Legislature . . . and it is unconstitutional for the Legislature to abdicate or transfer its legislative function to others.” Brower, 137 Wn.2d at 54. However:
“ [Conditioning the operative effect of a statute upon a future event specified by the Legislature does not transfer the state legislative power to render judgment to the persons or entity capable of bringing about that event. The Legislature, itself, determines the statute would be expedient only in certain circumstances. The power to make this judgment is not transferred merely because the circumstances may arise at the discretion of others. The substance of the act is complete in itself and the Legislature is the body which rendered the judgment as to the expediency of conditioning the operation of the statute upon the specified event.”
Brower, 137 Wn.2d at 54 (quoting Diversified Inv. P’ship v. Dep’t of Soc. & Health Servs., 113 Wn.2d 19, 28, 775 P.2d 947 (1989)); see also Royer v. Pub. Util. Dist. No. 1, 186 Wash. 142, 56 P.2d 1302 (1936); State v. Storey, 51 Wash. 630, 99 P. 878 (1909).
Here, appellants contend, the voters acted as legislators and determined that tax measures would be expedient only if approved by the voters. The State urges that although courts in other states are split on the question whether a condition of legislation may be statewide voter approval, the better view is that such a condition is constitutional. The cases that the State cites, however, each concern a specific piece of legislation conditioned on voter approval. See In re Opinions of the Justices, 232 Ala. 60, 166 So. 710, 714 (1936) (conditioning an act to legalize and tax alcoholic liquors on statewide voter approval did not constitute an unconstitutional delegation of legislative power); Hudspeth v. Swayze, 85 N.J.L. 592, 89 A. 780, 783-84 (1914) (conditioning an act concerning grand and petit juries on statewide voter approval did not constitute an unconstitutional *235delegation of legislative power); Smith v. City of Janesville, 26 Wis. 291 (1870) (act authorizing taxation of shares of stock in a national bank conditioned on statewide voter approval); State v. Scampini, 77 Vt. 92, 59 A. 201, 203 (1904) (legislature can condition effective date of act prohibiting sale of intoxicating liquor on statewide vote of people); People v. Collins, 3 Mich. 343, 361-62 (1854) (equally divided court on issue whether legislature can constitutionally submit an act prohibiting sale of intoxicating beverages to a statewide vote); cf. Marr v. Fisher, 182 Or. 383, 187 P.2d 966, 968-70 (1947) (act lowering income taxes conditioned on voter approval of measure establishing a sales tax did not involve unconstitutional delegation of legislative authority).
None of these cases cited by the State involves the question here—whether a legislative body (here the people) can require voter approval as a condition to all future taxing legislation passed by the Legislature, as opposed to a specific piece of legislation. Washington cases approving conditional legislation (but not involving statewide voter approval as the condition) also involve specific existing legislation. E.g., Brower, 137 Wn.2d 44; Diversified Inv. P’ship v. Dep’t of Soc. & Health Servs., 113 Wn.2d 19; Royer v. Pub. Util. Dish No. 1, 186 Wash. 142; State v. Storey, 51 Wash. 630. Here, section 2 encompasses all future state legislation imposing increased taxes as defined in 1-695.
Other cases cited by the State include Manly v. City of Raleigh, 57 N.C. 370, 377 (1859), which involved referral of a measure for a local vote but contains dictum approving of conditioning measures on a statewide vote. The North Carolina Supreme Court has noted more recently that the state constitution no longer contains a provision reserving all powers not granted to the legislature to the people (as did former article I, section 41 of the North Carolina State Constitution), and absent such a provision the legislature must legislate, not the people. Joytime Distribs. & Amusement Co. v. State, 338 S.C. 634, 528 S.E.2d 647 (1999), cert. *236denied, 529 U.S. 1087 (2000). The court rejected the argument that an act depending upon approval by the state’s voters, there an act pertaining to continuance of video gaming, could be valid as contingent legislation. The court reasoned that the act left to a majority of the voters the determination of expediency, and thus was an unconstitutional delegation of legislative authority.
The State also cites In re Municipal Suffrage to Women, 160 Mass. 586, 36 N.E. 488 (1894), where the majority held in an advisory opinion to the Massachusetts House of Representatives that it would be unconstitutional to submit to a statewide vote an act granting women the right to vote. The majority reasoned that although the constitution which the people adopted declared that all power originally resided in the people, authority was vested by the constitution in the various branches of government including the Legislature, as “ ‘their substitutes and agents,’ ” with no reservation to the people of the right of supervision. Id. 36 N.E. at 489. The majority said that the legislative power cannot be delegated, and that although conditional legislation may be passed by the Legislature, a measure cannot be conditioned on statewide voter approval because it would mean “that the legislative department declines to take the responsibility of passing the law; but the law has force, if at all, in consequence of the votes of the people.” Id. at 489-90.15 The State quotes the dissenting opinion of Oliver Wendell Holmes, who found nothing in the state constitution prohibiting such a law, and who reasoned that the Legislature should be able “to exercise its discretion by taking the opinion of its principal [the people], if it thinks that course to be wise.” Id. at 491-92 (Holmes, J., dissenting). The State reasons that, as Holmes argued, there is no unconstitutional delegation of legislative authority where the agents, the legislators, obtain the final decision from the principals (the people) on selected matters of important *237public policy questions such as the expediency of tax legislation. See also Hudspeth, 89 A. at 784.
In urging this analysis, the State points to language in article I, section 1, which states that “[a] 11 political power is inherent in the people . . . .”16 The Campaign also relies heavily on this language. The State says that it seems likely that the framers of our state constitution would have found it appropriate for the legislators or “agents” to refer matters of important public policy to their “principals.” The State then urges that because Washington’s voters adopted the rights of initiative and referendum, thus allowing for direct legislation, and provided for the Legislature to commence direct legislation by referendum, there is no demonstrated intent in our constitution to limit any preexisting legislative authority to enact legislation conditioned on voter approval. Since the people act in a legislative capacity in enacting law through the initiative process, their authority is similarly unlimited. Accordingly, in the State’s view, section 2’s voter approval requirement does not fall within article II, section 1. The State also reasons that there is no article II, section 1 issue here because the legislative power of the state is plenary, and any restriction on that power must be found in the constitution. Pub. Util. Dist. No. 1 v. Taxpayers & Ratepayers, 78 Wn.2d 724, 728, 479 P.2d 61 (1971). The State says that there is no provision in the constitution restricting the legislative power to require that tax measures be submitted to the voters for approval.
We do not accept the premise that because nothing in the constitution expressly restricts legislative power to condition state measures on voter approval, such power exists and there is no issue arising in this case under article II, section 1. There is no question that under article II, section 1 the Legislature cannot delegate its legislative authority. As noted, “ ‘[I]t is unconstitutional for the legislature to abdicate or transfer to others its legislative *238function.’ ” King County v. Taxpayers of King County, 133 Wn.2d 584, 605, 949 P.2d 1260 (1997) (quoting Keeting v. Pub. Util. Dist. No. 1, 49 Wn.2d 761, 767, 306 P.2d 762 (1957)); accord Brower, 137 Wn.2d at 54. The question here is not whether any other provision in the constitution prohibits conditioning state measures on voter approval, but whether such a condition unconstitutionally delegates legislative power in violation of article II, section 1.
As to the argument that the people have the inherent authority to approve legislation, while all political sovereignty initially resided with the people in this state, they expressly surrendered much of that sovereignty to the state government when they adopted the constitution. “Under our form of government, ultimate sovereignty, so far as the state is concerned, rests in its people, and so long as the government established by them exists, that sovereignty remains with them, except in so far as they have expressly surrendered it to a higher sovereignty.” Love v. King County, 181 Wash. 462, 467, 44 P.2d 175 (1935) (emphasis added) (also citing and quoting art. I, § 1). When the people adopted the constitution, they vested legislative power in the Legislature under article II, section 1. Later, when the Seventh Amendment was adopted, the people reserved to themselves the initiative and referendum powers, specifically setting forth the manner in which those powers may be exercised. However, “[t]he right to act directly through either the initiative or referendum is not an inherent right of the people. In fact, that right was nonexistent under our state constitution until Amendment 7 was adopted in 1912.” Ruano v. Spellman, 81 Wn.2d 820, 823, 505 P.2d 447 (1973).
Having surrendered legislative power with adoption of the constitution, the people did not retain inherent authority to approve state legislation, and the initiative and referendum powers are not the source of inherent authority either. Contrary to the position of the State and the Campaign, the people do not possess the inherent authority to approve state legislation.
*239The Campaign claims, though, that this court has noted the “extensive power of initiative” as: “[T]he people in their legislative capacity are superior to all other branches of government, superior to the legislature which made this law; in fact, supreme in their legislative capacity.” State ex rel. Berry v. Superior Ct., 92 Wash. 16, 26, 159 P. 92 (1916). The quote is taken out of context and its meaning thereby altered. The issue was whether the proponents of an initiative included argument in a preamble in the measure that constituted argument which under enabling statutes was unlawfully included within the text. The court held the preamble was argument advanced by the proponents in advocacy of the measure which, under the facilitating law, properly belonged in the voters pamphlet and paid for by the proponents. The quoted material appears in the court’s explanation that a proponent of an initiative is not a legislator, and in context states:
But, it is said, the people in their legislative capacity are superior to all other branches of government, superior to the legislature which made this law; in fact, supreme in their legislative capacity. The people in their legislative capacity are not, however, superior to the written and fixed constitution.
Id. at 26.
The next question is whether the people acquired the power to condition legislation on voter approval when they reserved the initiative and referendum rights. The answer begins with identifying the scope of the Legislature’s power before the people’s adoption of the Seventh Amendment, and determining whether the Legislature could then condition state tax measures on a vote of the people. A number of courts holding that conditioning an act on statewide voter approval is unconstitutional have done so on the basis that the legislature cannot delegate its legislative power to make law. See, e.g., People ex rel. Thomson v. Barnett, 344 Ill. 62, 176 N.E. 108 (1931); Barto v. Himrod, 8 N.Y. 483, 1853 WL 6039 (1853) (leading case); Brawner v. Curran, 141 Md. 586,119 A. 250 (1922); Akin v. Dir. of Revenue, 934 S.W.2d 295 (Mo. 1996); Opinion of the Justices, 143 N.H. *240429, 725 A.2d 1082 (1999); cf. In re Request of Governor Janklow, 530 N.W.2d 367 (S.D. 1995) (while legislature has authority to refer its own acts, it does not have authority to refer acts increasing rate of taxation). Courts have reasoned that when a legislature conditions legislation solely on a vote of the people, it relinquishes the decision to pass a law to the voters, thus delegating its legislative authority to make law to the voters. E.g., Opinion of the Justices, 725 A.2d 1082; Brawner v. Curran, 141 Md. 586; Barto, 8 N.Y. 483; Joytime Distribs., 528 S.E.2d 647. As the court explained in Opinion of the Justices:
If the people are to say, by way of popular vote, whether or not an act shall become law, they are put in the place of the legislature. The vote of the people becomes the determining factor whether an act shall be the law or not, not simply a contingency upon which certain things are or are not to be done under the law.
725 A.2d at 1092. In Barto, 8 N.Y. at 490-91, the court reasoned:
The wisdom or expediency of the free school act, abstractly considered, did not depend on the vote of the people. If it was unwise or inexpedient before that vote was taken, it was equally so afterwards. The event on which the act was made to take effect was nothing else than the vote of the people on the identical question which the constitution makes it the duty of the legislature itself to decide. The legislature has no power to make a statute dependent on such a contingency, because it would be confiding to others that legislative discretion which they are bound to exercise themselves, and which they can not delegate or commit to any other [s] ... to be exercised.
An important element in the analysis in these cases is that the people in the particular state reserved no legislative powers17 or that the state constitution did not provide for referrals of measures except in specific circumstances or both. E.g., In re Mun. Suffrage to Women, 160 Mass. 586, 36 *241N.E. 488 (1894); Barto, 8 N.Y. 483 (people voluntarily surrendered legislative power when adopting state constitution, limited only by provision reserving power to vote on laws for the contracting of debt); Joytime Distribs., 528 S.E.2d 647 (present state constitution does not contain a clause reserving to the people the power to legislate); Opinion of the Justices, 725 A.2d at 1087 (referenda on legislation are unconstitutional in New Hampshire unless specific constitutional provision permits).
As have these courts, we conclude that prior to the people’s adoption of the initiative and referendum powers in this state, the Legislature lacked the authority to condition measures on a vote of the people. Submitting a measure to the voters subject only to their approval would have transferred the determination of expediency of the measure to the voters, thus constituting an unlawful delegation of legislative power—which the people themselves had yielded to the Legislature in the state constitution. It would in effect have allowed a referendum vote on matters passed by the Legislature at a time when our state constitution did not permit referenda on legislative measures.18
With adoption of the initiative and referendum powers, which themselves are not inherent powers, Ruano, 81 Wn.2d at 823, the people reserved the right to legislate —“exercis [ing] the same power of sovereignty as that exercised by the legislature in the passage of a statute.” Love v. King County, 181 Wash. 462, 469, 44 P.2d 175 (1935). Because the Legislature lacked power to condition state measures solely on statewide voter approval, the same is true of the people exercising their legislative power once the initiative and referendum rights were reserved. Neither the Legislature nor the people acting in their legislative capacity has the power to condition a state law solely on voter approval, and accordingly section 2 is invalid, even if one were to accept the appellants’ argument that section 2 establishes a conditional legislation process.
*242This does not mean, however, that the people lack the authority to approve or disapprove legislation under the reserved initiative and referendum powers. They do. However, that right must be exercised in conformity with the constitutionally mandated procedures, including the four percent voter signature requirement each time the people petition for a referendum on a piece of legislation the Legislature has passed. Nor does it mean that the Legislature cannot refer a measure to the people for a statewide vote. Plainly it can do so, not, however, as conditional legislation, but rather through the referendum process set forth in article II, section 1(b).
We note there are other difficulties with the argument that section 2 merely establishes a valid conditional legislation process. If carried to its logical conclusion, it would mean that the voters could pass several initiatives, each requiring every measure of a certain class passed by the Legislature to be submitted to the voters for approval. In a piecemeal way, all, or nearly all, areas of legislation could thereby be removed from the Legislature’s authority. Such a result would be inconsistent with the representative form of government in this state. While we do have direct legislative authority of the people exercisable through the reserved initiative and referendum powers, the constitution also vests legislative authority in the Legislature as a representative body. Also, even though some courts have upheld a voter approval requirement as a condition of a particular measure, the State and the Campaign cite no cases, and none have been found, permitting conditioning all future state measures of a certain class on voter approval absent a constitutional amendment to that effect. Finally, under section 2 of 1-695 the legislation that is allegedly “conditioned” is not legislation enacted by the people acting in their legislative capacity but is instead legislation enacted by the Legislature. Thus, the legislative body passing the tax legislation is not the legislative body determining that effectiveness would be “expedient” only on approval of the voters.
*243The Campaign claims, though, that historically initiatives have provided similar tax limits while allowing higher limits as exceptions if approved by voters. The Campaign also says that the Legislature has often conditioned local taxing authority on voter approval, citing numerous statutes.
The initiatives referred to by the Campaign are Initiatives 64, 94, 114, and 129, and all concern taxation of real and personal property and limiting the rate of taxation while allowing for special levies upon voter approval. See RCW 84.52.050 (all the initiatives have to do with this statute). The Campaign’s reply brief expands upon the history of this type of voter approval, noting it ultimately has been adopted as article VII, section 2 of the state constitution. However, such voter approval requirements are unlike section 2 of 1-695. First, only a specified type of tax is at issue, not all future tax measures. Second, the voter approval provided for is only for local, not statewide, tax levies. As to the statutes cited, they also concern local, not statewide, voter approval provisions.
The Campaign maintains, though, that this court has upheld statutes conditioned on voter approval. The case it primarily relies upon concerns a local option law relating to sale of alcoholic beverages, not statewide voter approval. State v. Donovan, 61 Wash. 209, 210, 112 P. 260 (1910). As an early case noted, approval of such local option laws at that time was almost universal. Ex parte Beck, 162 Cal. 701, 709, 124 P. 543, 546 (1912) (citing numerous cases, including Donovan). The California court also noted that such laws relate to subjects which, like retailing alcoholic beverages or the running of cattle at large on the highways “ ‘may be differently regarded in different localities, and they are sustained on what seems to us the impregnable ground, that the subject, though not embraced within the ordinary power of the municipalities to make by-laws and ordinances, is nevertheless within the class of police regulations, in respect to which it is proper that local judgment should control.’ ” Beck, 162 Cal. at 708-09, 124 P. 546 *244(quoting Thomas M. Cooley, A Treatise on the Constitutional Limitations 174 (Victor H. Lane ed., 7th ed. 1903)); see also Opinion of the Justices, 725 A.2d at 1090-91 (noting an exception to the rule that enacting a law subject only to voter approval is an unconstitutional delegation of legislative authority; Legislature may delegate such authority where localities and matters of local concern are involved).
While not concerning local voter approval, the opinion in American Federation of Teachers, Yakima Local 1485 v. Yakima School District No. 7, 74 Wn.2d 865, 869, 447 P.2d 593 (1968) also recognizes the principle that an exception to the nondelegation rule exists where delegation to municipal corporations is involved:
“While the rule is fundamental that the power to make laws cannot be delegated, the creation of municipal corporations to exercise local self-government has never been deemed to violate this principle. Such legislation is not regarded as a transfer of general legislative power, but rather as a grant of the authority to prescribe local regulations, supported by immemorial practice, but subject, of course, to the interposition of the superior in cases of necessity. Conferring proper powers upon municipal corporations forms an exception to the rule which forbids the legislature to delegate any of its power to subordinate divisions.”
Id. at 869 (emphasis omitted) (quoting 2 Eugene McQuillin, The Law of Municipal Corporations § 4.09 (3d ed. 1966)).
We hold that section 2 of 1-695 violates the four percent signature requirement of article II, section 1(b) because it effectively establishes a referendum procedure applying to every piece of future taxing legislation without regard to the four percent signature requirement. Section 2 does not merely provide for conditional legislation; it changes the way in which a piece of legislation is enacted.
The next issue that the parties dispute is whether section 2’s unconstitutionality under article II, section 1(b) requires invalidation of section 2 or 1-695 in its entirety. The trial court reasoned that it would require redrafting 1-695 to avoid the unconstitutionality. The State contends that even if section 2 is invalid as to statewide measures, it is valid as to local taxing measures.
*245As a general proposition, it appears the State could impose a local voter approval requirement. The power to tax does not exist in a municipality absent a legislative grant of authority, City of Seattle v. Rogers Clothing for Men, Inc., 114 Wn.2d 213, 221, 787 P.2d 39 (1990), and the State retains the power to alter the delegated power to tax, Snow’s Mobile Homes, Inc. v. Morgan, 80 Wn.2d 283, 287-88, 494 P.2d 216 (1972). However, since section 2 and 1-695 are unconstitutional in their entirety under article II, section 19, section 2 retains no validity with respect to local taxing measures.19
3. Article II, section 37
Article II, section 37 provides that “[n]o act shall ever be revised or amended by mere reference to its title, but the act revised or the section amended shall be set forth at fall length.” This provision is to be given a reasonable construction. In re Application of Dietrich, 32 Wash. 471, 477, 73 P. 506 (1903). The first purpose of this provision is to “ ‘avoid [] confusion, ambiguity, and uncertainty in the statutory law through the existence of separate and disconnected legislative provisions, original and amendatory, scattered through different volumes or different portions of the same volume.’ ” Flanders v. Morris, 88 Wn.2d 183, 189, 558 P.2d 769 (1977) (quoting State ex rel. Gebhardt v. Superior Ct., 15 Wn.2d 673, 685, 131 P.2d 943 (1942)); see State ex rel. Wash. Toll Bridge Auth. v. Yelle, 54 Wn.2d 545, 342 P.2d 588 (1959). Stated more succinctly, this purpose is to disclose the effect of the new legislation. State v. Thorne, 129 Wn.2d 736, 753, 921 P.2d 514 (1996). The result of compliance with article II, section 37 should be “ ‘that no further search will be required to determine the provisions of such section as amended.’ ” Flanders, 88 Wn.2d at 189 (quoting Gebhardt, 15 Wn.2d at 685).
*246However, an act is exempt from the requirements of article II, section 37 provided the act is “complete in itself, independent of prior acts, and stand [s] alone as the law on the particular subject of which it treats.” State ex rel. Living Servs., Inc. v. Thompson, 95 Wn.2d 753, 756, 630 P.2d 925 (1981). If, though,
the new act is not complete but refers to a prior statute which is changed but not repealed by the new act, one is required to read both statutes before the full declaration of the legislative will on the subject can be ascertained. This causes the very obscurity and tendency to confuse which the constitutional provision seeks to prevent, hence violates the constitution.
Living Servs., 95 Wn.2d at 757. Thus, the first test to determine whether article II, section 37 is violated is related to the first purpose of the provision: “Is the new enactment such a complete act that the scope of the rights or duties created or affected by the legislation action can be determined without referring to any other statute or enactment?” Wash. Educ. Ass’n v. State, 93 Wn.2d 37, 40, 604 P.2d 950 (1980) (citing Naccarato v. Sullivan, 46 Wn.2d 67, 74, 278 P.2d 641 (1955)); see Thorne, 129 Wn.2d at 753-54.
The second purpose of the constitutional provision “is the necessity of insuring that legislators are aware of the nature and content of the law which is being amended and the effect of the amendment upon it.” Flanders, 88 Wn.2d at 189. Or, stated another way, to disclose the act’s impact on existing laws. Thorne, 129 Wn.2d at 753. The second test for compliance with article II, section 37 is, therefore, “[w]ould a straightforward determination of the scope of rights or duties under the existing statutes be rendered erroneous by the new enactment?” Wash. Educ. Ass’n, 93 Wn.2d at 41 (citing Weyerhaeuser Co. v. King County, 91 Wn.2d 721, 731, 592 P.2d 1108 (1979)); see Thorne, 129 Wn.2d at 753-54.
This court said in Spokane Grain & Fuel Co. v. Lyttaker, 59 Wash. 76, 78, 109 P. 316 (1910):
“The mischief designed to be remedied was the enactment of amendatory statutes in terms so blind that legislators them*247selves were sometimes deceived in regard to their effect, and the public, from the difficulty in making the necessary examination and comparison, failed to become apprised of the changes made in the laws. An amendatory act which purported only to insert certain words, or to substitute one phrase for another in an act or section which was only referred to but not re-published, was well calculated to mislead the careless as to its effect, and was, perhaps, sometimes drawn in that form for that express purpose. Endless confusion was thus introduced into the law, and the constitution wisely prohibited such legislation. But an act complete in itself is not within the mischief designed to be remedied by this provision, and cannot be held to be prohibited by it without violating its plain intent.”
(quoting Cooley, J., in People ex rel. Drake v. Mahaney, 13 Mich. 481 (1865)).
Article II, section 37 applies to initiatives. Thorne, 129 Wn.2d at 753.
The trial court ruled that 1-695 is not a complete act in itself, and that it renders existing statutes erroneous. As to the second test, the trial court reasoned that the initiative fails to identify by number many statutes which are directly affected and modified by 1-695.
The State contends that the voter approval provision meets the two tests for compliance with article II, section 37. First, the State argues, it is a complete provision that can be understood without reference to any other statutes; it is unnecessary to read any other statute to understand the voter approval requirement. The State maintains that the State can articulate the voter approval requirement in the body of legislation, and local governments can implement the requirement under existing authority. The State adds that if there are ambiguities as to the requirements for voter approval, these can be resolved in the same way ambiguities in statutes are generally resolved—through executive and legislative implementation subject to judicial review. The State points out that the Administrative Procedure Act, chapter 34.05 RCW; the Open Public Meetings Act, chapter 42.30 RCW; and the State Environmental *248Policy Act, chapter 43.21C RCW are “overlay” acts which restrict other laws, and they have been the subject of many lawsuits, but are not any less complete.
As to the second test used to analyze an article II, section 37 question, the State says that 1-695 does not render existing statutes erroneous. It says that rather than alter or amend other laws, 1-695 provides a requirement that is not addressed by other laws. The State compares this case to cases addressing Initiative 593, the “three strikes” initiative. That initiative imposed a new, mandatory life sentence on persistent offenders. Defendants argued that the initiative was void because it unconstitutionally amended existing statutes concerning maximum sentences without setting them forth. Thorne, 129 Wn.2d at 752; State v. Manussier, 129 Wn.2d 652, 662-63, 921 P.2d 473 (1996). The court reasoned in these cases that where the new enactment is a complete act, the fact that it “renders erroneous” existing statutes, in the sense they are impliedly amended (or modified) by the new enactment, no violation of article II, section 37 occurs. Thorne, 129 Wn.2d at 755; Manussier, 129 Wn.2d at 664-65. “A complete act, not revisory in character, is not rendered unconstitutional by article II, section 37, even though it may by implication operate to change or modify prior acts.” Manussier, 129 Wn.2d at 664-65 (citing Wash. Educ. Ass’n v. State, 97 Wn.2d 899, 905, 652 P.2d 1347 (1982)). The constitutional provision is not “ ‘ “intended to prohibit the passage of a law which declared fully its provisions without direct reference to any other act, although its effect should be to enlarge or restrict the operation of some other statutes.” ’ ” Thorne, 129 Wn.2d at 755 (quoting Wash. Educ. Ass’n, 97 Wn.2d at 906) (quoting Spokane Grain & Fuel Co., 59 Wash. at 80-81)).
Although a complete act may modify, and thus render erroneous, an existing statute, this does not contravene the purpose of article II, section 37, to protect the members of the Legislature against fraud and deception. Thorne, 129 Wn.2d at 756.
The Campaign generally agrees with the State’s argu*249ments, reasoning among other things that 1-695 applies to every tax, and thus does not render other taxing authorities superfluous, contrary to the trial court’s ruling. The Campaign says that where violations of article II, section 37 have been found, the acts were “unintelligible.” See Thorne, 129 Wn.2d at 753. For example, the Campaign cites Flanders, where an uncodified appropriations bill which provided a new substantive restriction on public assistance was held to violate article II, section 37. As the court there noted, one seeking to know the law on the subject would never find the restriction in the public assistance statutes, and would have to look under an appropriations title in the uncodified session laws to find the substantive restriction. Flanders, 88 Wn.2d at 189. This kind of constitutional infirmity is not found in 1-695, the Campaign urges. The Campaign says the voter approval requirement of 1-695 is completely declared in the measure, and one need look no further. The Campaign also says that all the preexisting authority of respondents remains, but it is now further conditioned.20
Amalgamated Transit and the Tacoma Water respondents rely on Weyerhaeuser Co. v. King County, 91 Wn.2d 721, 731, 592 P.2d 1108 (1979) for the proposition that the test for whether a new enactment is an amendment which must set forth the text of existing statutes is “whether [the new act] changes [the] prior act in scope and effect.” Amalgamated Transit says that 1-695 substantially alters the scope and effect of many statutes relating to voter approval of local enactments without setting them forth. For example, Amalgamated Transit says that one reading RCW 35A. 11.090, concerning noncharter cities and referenda on tax levies, would be unaware that 1-695 has altered *250this statute. The Tacoma Water respondents say that the scope and effect of provisions in Titles 35 RCW and 57 RCW, relating to these respondents’ authority and duties to set and collect water rates and charges, is changed by 1-695. The Tacoma Water respondents say that like the situation in Weyerhaeuser, 1-695 deprived them of most of their authority to set rates and charges. Although not relying on Weyerhaeuser, the Port Districts make a similar argument, i.e., that comprehensive statutory schemes exist concerning port districts’ authorization to negotiate leases, set charges and tariffs, and to impose assessments. They maintain that I-695’s imposition of a public vote fundamentally conflicts with the prescribed legislative processes, and that 1-695 cannot amend the power of Port Districts without setting forth the amended statutes in full. The Port Districts particularly rely on Washington Education Association, 93 Wn.2d 37.
Turning first to Weyerhaeuser, that opinion does say that the test is whether a new act changes a prior act in scope and effect. The court in Weyerhaeuser held that a section of an act amending the Forest Practices Act of 1974 (FPA), RCW 76.09.010-.280 amended the Shoreline Management Act of 1971 (SMA), chapter 90.58 RCW, without setting forth the text of the SMA. The new enactment prohibited imposition of any regulations other than Department of Natural Resources’ regulations on shoreline forest practices, contravening the intent of the SMA that shoreline master programs control. It also deprived local governments of enforcement power under the SMA by prohibiting any enforcement other than by procedures in the FPA. The court reasoned that the effect of the new enactment was to substantially change the scope and effect of the SMA without changing the language of the SMA to reflect the changes. 91 Wn.2d at 731-32. The court in Weyerhaeuser said that the new enactment could not be understood without reference to both the FPA and SMA, and was therefore not a complete act and not excepted from the article II, section 37 requirement. Id. at 732.
If some of its statements are taken literally, Weyerhaeuser *251is inconsistent with the body of law in this area. As the dissent pointed out, acts which are exempt from the requirement of article II, section 37 are:
“(1) [C]omplete acts which repeal prior acts or sections thereof on the same subject; (2) complete acts which adopt by reference provisions of prior acts; (3) complete acts which supplement prior acts or sections thereof without repealing them; [and] (4) complete acts which incidentally or impliedly amend prior acts.”
Weyerhaeuser, 91 Wn.2d at 738 (Dolliver, J., dissenting) (quoting Naccarato v. Sullivan, 46 Wn.2d 67, 75, 278 P.2d 641 (1955)). As the dissent pointed out, the lead case on the meaning of article II, section 37 is Spokane Grain. The court there said:
But how often must we look to two or more acts to ascertain the full declaration of the legislative will. No one will for a moment doubt the power of the legislature to exempt homesteads by one act, household goods by another, farming implements by a third, and so on; yet the full declaration of the legislative will on the subject of exemptions could only be gathered by referring to these several acts. Followed to its logical conclusion, this argument would compel the legislature to embody in a single enactment, or in amendments thereto, all legislation relating to a single subject. Such was not the object or purpose of the provision in question. So long as a legislative act is complete in itself and does not tend to mislead or deceive, it is not violative of the constitution.
Spokane Grain, 59 Wash. at 84, quoted in Weyerhaeuser, 91 Wn.2d at 739 (Dolliver, J., dissenting).
Recognizing that the dissent did not prevail, nevertheless it is important that Weyerhaeuser not be read too broadly. First, as indicated in Spokane Grain, Weyerhaeuser’s statement that the need to look to two acts to know the law means that the later act is not a complete act and is too broad. Further, Weyerhaeuser also too broadly states the test for whether the requirement of article II, section 37 must be followed is whether the later enactment “changes [the] prior act in scope and effect.” A later enactment which *252is a complete act may very well change prior acts and is exempt from the requirement of article II, section 37.
However, aside from such statements, the new enactment in Weyerhaeuser clearly violated article II, section 37. The new enactment specifically altered some of the provisions of the SMA (stating that local entities could exercise any authority under the SMA “except that in relation to ‘shorelines’ as defined in RCW 90.58.030, the following shall apply [then describing exceptions to that authority,]” and providing that with the exceptions stated (in the new FPA), the authority of local government was unchanged, Laws of 1975, 1st Ex. Sess., ch. 200, § 11). This is the kind of amendment of an existing statute which article II, section 37 addresses.
However, the constitutional provision does not apply in all cases where a new act, in effect, amends another; where the new law is independent, and no further search is required to know the law which the new act covers, the new act does not come within the constitutional provision. Dietrick, 32 Wash. at 479-80.
As to Washington Education Association, the court there held that a new enactment which set statewide limitations on public school salaries was unconstitutional because it did not set forth existing statutes which were amended. The new act merely provided that no school district could grant a salary increase greater than a certain amount, but did not specify what powers remained with the district or whether a district had the power to grant raises at all. 93 Wn.2d at 40. Moreover, a straightforward reading of the existing statutes indicated that the district had the power to expend funds as it chose on teachers’ salaries, and the challenged act purported to amend this authority. Id. at 41. Thus, the measure satisfied neither of the two tests used to determine if article II, section 37’s requirement had to be followed.
Amalgamated Transit also contends that this case is not like Thorne and Manussier. It argues that modification is not apparent from reading I-695’s provisions. Amalgamated Transit says that one interested in knowing the law appli*253cable to local referenda, for example, would have no reason to look in the code chapter on state expenditure limitations. Amicus Curiae League of Women Voters of Washington similarly argues that prior to 1-695, voters had to approve only real property tax levies which exceeded the prior levy by 106 percent, RCW 84.55.010, but 1-695 changed this without amending chapter 84.55 RCW. Amicus League of Women Voters says that a voter reading chapter 84.55 RCW would be unaware that 1-695 changed this law. Amicus League of Women Voters says that because voters could no longer discern the law from reading statutory provisions regarding limitations on property tax levies, 1-695 violates article II, section 37.
These arguments disclose that the second test for when a new enactment must comply with article II, section 37 can sometimes be misleading. As noted, that question asks “[w]ould a straightforward determination of the scope of rights or duties under the existing statutes be rendered erroneous by the new enactment?” Wash. Educ. Ass’n, 93 Wn.2d at 41 (citing Weyerhaeuser, 91 Wn.2d at 731). This question cannot be answered in isolation because complete acts may well result in a person reading an existing statute and being unaware there is new law on the subject. Thus, it is not enough to ask whether one reading an existing statute would be aware that a new enactment changes it.
Nevertheless, section 2’s voter approval requirement violates article II, section 37. Although numerous arguments are raised, one example shows why. RCW 53.36.100 requires a public vote if, but only if, a port district seeks to extend an industrial improvement district assessment beyond a six-year period. 1-695 contains a more general voter approval provision that applies in general to such assessments. 1-695 does not repeal or mention the existing statute, but it clearly has impact since it encompasses voter approval for all taxes. However, because both statutes contain voter approval requirements, the impact is not at all clear. At the least, one would not know the law by referring to the existing statute. Nor can it be said that *254section 2 stands alone on the subject in light of the existing statute’s voter approval requirement, which specifically describes how and when a special election is to be held, and what percentage of voters must approve. See RCW 53.36.100. Section 2 of 1-695 is therefore not complete. 1-695 does not set forth the existing statute which is affected nor does it show how it is impacted.
Section 3 is also a focus of the article II, section 37 arguments. Initially, there is a general issue regarding repeals. Section 3 of 1-695 repealed a number of statutes, and the question is whether repealed statutes must be set forth in the repealing act. The State contends that statutory repeals are outside the scope of article II, section 37. This court has held that statutes must be set forth in full only when they are revised or amended, but not when they are repealed. State v. Frazier, 81 Wn.2d 628, 632, 503 P.2d 1073 (1972). It is urged, though, that this rule applies only when statutes are repealed by complete acts. See Naccarato, 46 Wn.2d at 75. The constitutional provision applies where “act[s are] revised or amended[.]” Art. II, § 37. It is clear by this language that repealers are not within article II, section 37 whether the new act is complete or not.
Turning to more specific arguments regarding section 3, the Cities argue that section 3 attempts to eliminate funding for many important programs, and therefore it has an enormous impact on existing laws which is not disclosed in violation of article II, section 37. Amicus Curiae of Kincheloe, Schindler, and the Washington Coalition of Citizens with Disabilities (Coalition) make a similar argument. Amicus Coalition contends that section 3’s repeal of RCW 82.44.110, .150, and .180 drastically altered the public transportation system, eliminating services for persons with disabilities. These statutes were not, Amicus Coalition argues, related to imposition of taxes, but instead concerned allocation of revenues to public transportation. Amicus Coalition says that the voters could not reasonably know from 1-695 that one of its direct effects would be the loss of public transportation. Amici contend that public *255debate before the election is insufficient notice of the effect of 1-695, because that public debate might not reach all members of the public.
It is clear, though, that with repeal of the MVET, funding would be affected. 1-695 cannot be said to be incomplete as to the subject of eliminating the MVET. Accordingly, these arguments are unpersuasive.21
Amicus League of Women Voters makes another argument respecting sections 1 and 3 of 1-695. It says that persons considering 1-695 alone would conclude that they would have to pay only a $30 license fee, but in fact some other fees would have to be paid. Amicus League of Women Voters says that 1-695 neither repealed these fees nor disclosed them to the voters, and that voters must refer to more than 1-695 to know the law respecting license tab fees. For this reason, Amicus League of Women Voters says, 1-695 is unconstitutional. However, this argument fails to appreciate that by the terms of the constitutional provision itself, acts “revised” or “section [s] amended” must be set forth. Art. II, § 37. The fees identified by Amicus League of Women Voters are not affected by 1-695.
The Tacoma Water respondents say that section 3 does not disclose that 1-695 revised or changed provisions in Titles 35 RCW and 57 RCW which set forth their right and duty to set and collect water rates and charges. They maintain that this failure means that 1-695 does not allow the average informed voter to make an informed conclusion as to which tax, fee, and charge statutes were being changed to include a voter approval requirement. The Cities similarly state that 1-695 would render superfluous virtually every statute which gives cities revenue-generat*256ing authority, and voters would have no way to tell which statutes are affected. These arguments are unpersuasive, because 1-695 discloses that all increased taxes are subject to voter approval.
The Cities also argue that aside from the statutes which 1-695 states are repealed, the initiative effectively strips cities of their statutory authority to raise revenues, thus making a fundamental change in the authority of municipal governments. The inability to tax without voter approval is disclosed by 1-695, however.
We hold that section 3 does not violate article II, section 37.
Finally, the State urges that if the court holds that 1-695 violates article II, section 37, the remedy is not invalidation of1-695, but rather a declaration that the other law continues in force. We disagree. Invalidation of the unconstitutional enactment is the proper remedy. See, e.g., Rourke v. Dep’t of Labor & Indus., 41 Wn.2d 310, 314, 249 P.2d 236 (1952); Weyerhaeuser, 91 Wn.2d at 733; Wash. Educ. Ass’n, 93 Wn.2d at 41.
Here, as to the subject matter of section 2, voter approval, 1-695 is not complete, and it fails to disclose its effect on an existing voter approval statute. This, in and of itself, constitutes a violation of article II, section 37, and section 2 is accordingly invalid.
Finally, in light of our decision, the appellants’ motions for a stay of the trial court’s order enjoining implementation and enforcement of section 2 of 1-695 are moot.
CONCLUSION
1-695 violates several state constitutional provisions. It contains two subjects in violation of article II, section 19, thus placing citizens in the position of being asked to decide two unrelated laws with only one vote. 1-695 also violates article II, section 19 because the subject of voter approval of tax increases is not adequately set forth in the title of the initiative; the title fails to disclose that the term “tax” does not have its common meaning in the body of the initiative. *257The disparity between the title and the text fails to notify voters of the breadth of the law’s reach. Section 2 of 1-695 also violates article II, section 1(b) because it establishes a referendum procedure which does not comport with the four percent signature requirement of constitutional provision. This fundamental shift in legislative authority requires a constitutional amendment which cannot be accomplished by initiative. Finally, section 2 of 1-695 violates article II, section 37 because it fails to set forth an existing law that is amended or revised by 1-695, thus causing confusion, ambiguity and conflict in respect to existing law.
The trial court’s judgment declaring 1-695 unconstitutional in its entirety is affirmed.

In Citizens for Financially Responsible Government v. City of Spokane, 99 Wn.2d 339, 351, 662 P.2d 845 (1983), for example, the court said that the issue of the right of referendum over taxing ordinances in the face of the Spokane City Charter, and “comparable situations,” were matters of “continuing and substantial interest and one presenting a question of a public nature which is likely to recur,” and therefore even if amendment of the ordinance at issue rendered the case moot, review was proper.
In any event, it is clear that most, if not all, of the respondents have standing and their claims are justiciable. As a practical matter, our rulings on the constitutionality of 1-695 will apply to all respondents.
As noted, we have held that the question of a plaintiff’s right to sue under the Uniform Declaratory Judgments Act is a question of jurisdiction, which may be raised at any time. Wash. Beauty Coll., Inc. v. Huse, 195 Wash. 160, 80 P.2d 403 (1938); see also, e.g., Kitsap County v. City of Bremerton, 46 Wn.2d 362, 366, 281 P.2d 841 (1955); Galvin v. Tax Comm’n, 56 Wn.2d 738, 743, 355 P.2d 362 (1960). However, courts in other jurisdictions are split on the question whether standing in a declaratory judgment action is a jurisdictional question that can be raised at any time. Some courts hold that it is. E.g., Prudential-Bache Sec., Inc. v. Comm’r of Revenue, 412 Mass. 243, 248, 588 N.E.2d 639, 642 (1992); Citizens Ins. Co. of Am. v. Leiendecker, 962 S.W.2d 446, 449 (Mo. Ct. App. 1998); Gorman v. Gorman, 966 S.W.2d 858, 864 (Texas App. 1998). Other courts have held in declaratory judgment actions that standing will not be considered for the first time on appeal. E.g., City of Tucson v. Woods, 191 Ariz. 523, 526 n.2, 959 P.2d 394, 397 n.2 (Ct. App. 1997); Gasoline Marketers of Vt., Inc. v. Agency of Natural Res., 169 Vt. 504, 739 A.2d 1230, 1233 n.3 (1999); County of Butler v. Local 586, Serv. Employees Int’l Union, 744 A.2d 338, 341 n.4 (Pa. Commw. Ct. 1999).
Some courts addressing standing have noted the importance of the standing *204doctrine to assure that a court does not render advisory opinions which may encroach on the authority of other branches of government. Thus, the separation of powers doctrine has served as a constitutional underpinning to the standing doctrine which has led courts to conclude that standing is a matter which, whether viewed as a component of jurisdiction or justiciability, may be raised for the first time on appeal. E.g., Tex. Ass’n of Bus. v. Texas Air Control Bd., 852 S.W.2d 440, 444-45 (Tex. 1993) (in context of declaratory judgment action); Terracor v. Utah Bd. of State Lands & Forestry, 716 P.2d 796, 799 (Utah 1986); City of Indianapolis ex rel. City-County Council v. Ind. State Bd. of Tax Comm’rs, 261 Ind. 635, 637-38, 308 N.E.2d 868, 869-70 (1974). This court alluded to the same concern in the case in which it determined that the Uniform Declaratory Judgments Act is constitutional. Acme Fin. Co. v. Huse, 192 Wash. 96, 101-02, 73 P.2d 341 (1937).
However, we have held that outside the context of the Uniform Declaratory Judgments Act, standing is an issue that must be raised in the trial court. E.g., Baker v. Teachers Ins. & Annuities Ass’n Coll. Retirement Equity Funds, 91 Wn.2d 482, 484, 588 P.2d 1164 (1979); Tyler Pipe Indus., Inc. v. Dep’t of Revenue, 105 Wn.2d 318, 327, 715 P.2d 123 (1986), vacated on other grounds, 483 U.S. 232 (1987). In addition to constitutional questions, the Uniform Declaratory Judgments Act authorizes courts to declare private rights, such as the validity or construction of deeds, wills, and contracts. In such contexts, there is little cause for concern about encroachment on the powers of the other branches of government. However, we need not resolve the issue in this case and will leave for a future case, with proper briefing, the question whether we will retain the rule that standing may be raised for the first time on appeal in any, or all, declaratory judgment actions.
In the trial court, the Campaign offered evidence of a poll taken which it claimed showed that logrolling did not in fact occur in this case because 65 percent of those polled supported 1-695 and 73 percent supported the voter approval provision. The trial court said that even assuming the validity of the poll, it could still not be determined whether the $30 license tab fee provision or the voter approval provision or both would have been approved. The Campaign says it is not logrolling to include related and equally popular sections. First, there is no requirement that a challenger alleging a violation of article II, section 19 show that there has been logrolling in fact. Second, there is no basis for determining whether the September 1999 KOMO-TV-Eastside Journal poll, Clerk’s Papers at 207, accurately reflected voter opinion when 1-695 was voted on.
Vashon-Maury joins Amalgamated Transit’s arguments on all issues.
The meaning of the term “tax” is addressed in the next section discussing whether 1-695 violates the subject-in-title requirement of article II, section 19.
Amicus League of Women Voters also argues in this part of its brief that there is no rational unity between limiting license tab fees and establishing a method of approval for all tax increases. However, Yelle, 32 Wn.2d 13, concerns a restrictive title, and where a restrictive title is used, the rational unity analysis does not apply.
However, where the Legislature removes a provision from a bill by amendment, but a reference to that provision continues to appear in the title, no violation of article II, section 19 occurs. Brower v. State, 137 Wn.2d 44, 71, 969 P.2d 42 (1998); State v. Carroll, 81 Wn.2d 95, 102, 500 P.2d 115 (1972).
At oral argument the Campaign argued that the ballot title also uses the term “fees,” and not just the term “taxes.” However, the title quite expressly links the voter approval provision solely to “taxes.” “Fees” are mentioned in the title solely with regard to license tab fees: “Shall voter approval be required for any tax increase, license tab fees be $30 per year for motor vehicles, and existing vehicle taxes be repealed?” Voters Pamphlet at 4.
These include: RCW 82.44.110; RCW 82.44.150; RCW 82.44.155; RCW 82.44.157; RCW 82.44.160; RCW 82.44.170; RCW 82.44.180; and RCW 82.44.900.
These statutes include RCW 82.44.015; RCW 82.44.022; RCW 82.44.023; and RCW 82.44.025.
Article II, section 1(b) grants the Legislature discretionary authority to refer measures it passes to the people. Brower v. State, 137 Wn.2d 44, 56, 969 P.2d 42 (1998). Section 2 does not permit any discretion on the part of the Legislature to refer tax measures to the people.
The State contrasts this situation with that in California, where the people through the initiative power may bind future legislative bodies, citing Rossi v. Brown, 9 Cal. 4th 688, 889 P.2d 557, 574, 38 Cal. Rptr. 2d 363 (1995). Under the California State Constitution, a measure enacted by initiative is subject to amendment or repeal only through the initiative process.
The Massachusetts Constitution has subsequently been amended to provide for initiative and referendum. See Mass. Const, amend. XLII (1913) (superseded 1918) and amend. XLVIII (1918).
Article I, section 1 states in full that “[a] 11 political power is inherent in the people, and governments derive their just powers from the consent of the governed, and are established to protect and maintain individual rights.”
This reasoning would undercut the appellants’ argument that the voter approval provision does not involve direct legislation. Many courts have viewed voter approval as involving legislative authority.
If such referenda had been permitted, there would have been no need for adoption of the Seventh Amendment.
We do not wish to leave the impression that, absent the constitutional infirmities under article II, sections 1, 19 and 37, section 2 would be valid as to voter approval for all local tax measures. There may be circumstances where a local voter approval provision would not pass constitutional muster for reasons other than addressed in this opinion.
The Campaign also contends that 1-695 is supplementary because it does not purport to amend existing statutes, and therefore the text of all statutes affected need not be set forth. A supplementary law is one which adds to, but does not alter, an existing act. State ex rel. Living Servs., Inc. v. Thompson, 95 Wn.2d 753, 757, 630 P.2d 925 (1981). The Tacoma Water respondents maintain, though, that contrary to the State’s and the Campaign’s characterization of1-695 as an overlay, it does not merely overlay existing statutes, but instead alters them. Respondents appear to be correct; 1-695 is not a supplementary law, as it alters a number of existing statutes.
Amalgamated Transit says that 1-695 is not complete because the only way to understand the meaning of section 3 is to look at each of the statutes it repeals. However, that is always true when laws are repealed. Given that an act need not set forth statutes on the same subject it repeals, Amalgamated Transit’s premise is false. Amalgamated Transit also says that the substantive repeal of the MVET occurred in section 3 alone, and this kind of “substantive repealer” is subject to article II, section 37. This conclusion is unsound. By setting vehicle license tab fees at $30, section 1 of 1-695 eliminated the MVET.
