In these two consolidated proceedings, plaintiffs seek to invalidate Ballot Measure 7 (2000), set out post, 334 Or at 665-67, an initiated amendment to the Oregon Constitution that the voters approved at the 2000 general election. The trial court agreed with plaintiffs that Measure 7 was adopted in violation of the “separate-vote” requirement of Article XVII, section 1, of the Oregon Constitution, also set out post. The trial court therefore declared Measure 7 to be invalid and entered judgment accordingly. The state1 appealed to the Court of Appeals, that court certified the appeals to this court, and this court accepted certification. We now hold, as did the trial court, that Measure 7 was adopted in violation of the separate-vote requirement set out in Article XVII, section 1, and, therefore, is void in its entirety.
I. FACTS AND PROCEDURAL BACKGROUND
On November 7, 2000, the voters appear to have approved Measure 7,2 which, generally speaking, would have added to Article I, section 18, of the Oregon Constitution text requiring governments to compensate private real property owners for the cost of “restrict [ive]” regulations that reduce the value of their real property. On November 24, 2000, before the Secretary of State had completed canvassing the votes on Measure 7, McCall plaintiffs filed their complaint, alleging that the measure was invalid because it was adopted in violation of various provisions of the Oregon Constitution, including Article XVII, section 1, which sets out a separate-vote requirement for constitutional amendments.3 In their *650complaint, McCall plaintiffs sought a judicial declaration that Measure 7 was not validly adopted, and, three days after filing their complaint, they moved for a preliminary injunction preventing the Secretary of State from canvassing the votes on the measure and preventing the Governor from declaring whether the measure had passed. League of Oregon Cities (League) plaintiffs 4 filed their complaint on December 5, 2000, also before completion of canvassing, raising essentially the same constitutional challenges as McCall plaintiffs and also seeking a declaratory judgment; League plaintiffs simultaneously moved for a preliminary injunction. McCall plaintiffs, but not League plaintiffs, also specifically sought recovery of attorney fees. In its answer to both complaints, the state asserted that some or all plaintiffs lacked standing and that the trial court lacked subject matter jurisdiction over both actions.
In December 2000, the trial court consolidated the actions and issued a preliminary injunction, enjoining the Secretary of State from canvassing the votes on Measure 7 and the Governor from declaring or proclaiming the results of the election. In early January 2001, Miller (intervenor), originally the chief petitioner of the initiative petition that ultimately became Measure 7, moved to intervene in the consolidated actions, and the trial court granted that motion. In his answer, intervenor contended, among other things, that the actions were not ripe for adjudication and that all plaintiffs lacked standing.
Shortly thereafter, all plaintiffs filed motions for summary judgment, and the state and intervenor filed cross-motions for summary judgment. At the summary judgment hearing, intervenor submitted evidence that set out the official county election results and demonstrated that Measure 7 had received more than 53 percent of the vote.
*651In February 2001, the trial court granted plaintiffs’ motions for summary judgment and denied the state’s and intervenor’s cross-motions. The court rejected the state’s and intervenor’s arguments respecting jurisdiction, standing (except, as noted, the argument concerning plaintiff League of Oregon Cities), and ripeness, and also rejected most of plaintiffs’ constitutional arguments. However, the court agreed with plaintiffs that Measure 7 violated the separate-vote provision of Article XVII, section 1, of the Oregon Constitution and, accordingly, was invalid. The court later entered judgment in both actions, declaring that the measure should not have been submitted to the voters, had not become effective, and was not part of the Oregon Constitution.5
The state appealed, and the Court of Appeals certified the appeals to this court. This court accepted the certification and consolidated the proceedings for purposes of appeal.
II. JURISDICTION
A. Jurisdiction under the Uniform Declaratory Judgments Act
The state contended below that the trial court did not have subject matter jurisdiction because plaintiffs filed their challenges to Measure 7 after the election, but before the Secretary of State had completed the process of canvassing the votes and certifying the measure. The trial court disagreed and assumed jurisdiction under ORS 28.010 to 28.160, the Uniform Declaratory Judgments Act (UDJA). On appeal, the state and intervenor argue that the trial court erred in assuming jurisdiction under the UDJA because another statute, ORS 250.044(1), provided plaintiffs with the exclusive method of challenging a ballot measure after the election. The state, but not intervenor, alternatively argues *652that, even if ORS 250.044(1) did not provide an exclusive method for plaintiffs’ challenge, it at least provided a more appropriate method for the challenges at issue here. For the reasons set out below, we disagree with both contentions and hold that the trial court did not err in assuming jurisdiction under the UD JA.
ORS 28.010 provides, in part:
“Courts * * * within their respective jurisdictions shall have power to declare rights, status, and other legal relations, whether or not further relief is or could be claimed. * *
Although a trial court has broad power to provide declaratory relief, it lacks subject matter jurisdiction under ORS 28.010 if some other exclusive remedy exists. Alto v. State Fire Marshal, 319 Or 382, 395, 876 P2d 774 (1994). In addition, the trial court should decline to exercise its jurisdiction under ORS 28.010 if some more appropriate remedy exists. Brooks v. Dierker, 275 Or 619, 624, 552 P2d 553 (1976).
The state first argues that ORS 250.044(1)6 is the type of exclusive remedy addressed in Alto that prevents a trial court from assuming jurisdiction under ORS 28.010. As this court explained in Swett v. Bradbury, 333 Or 597, 605, 43 P3d 1094 (2002), decided after oral argument in this case, ORS 250.044(1) is not “exclusive” in the manner that the state asserts. That statute does not concern all ballot measure challenges; rather, it concerns only those ballot measure challenges brought on constitutional grounds during the six-month period after the Secretary of State certifies that the electors have adopted the challenged measure. Id. As in *653Swett, plaintiffs here did not file their challenges within that time period; consequently, ORS 250.044(1) does not apply to their actions.
The state’s alternative argument — that ORS 250.044(1) nonetheless would have provided a more appropriate avenue for plaintiffs’ challenges — incorrectly assumes that ORS 250.044(1) provides an independent basis for circuit court jurisdiction over a ballot measure challenge. In other words, the state argues that, if plaintiffs had waited until after certification, ORS 250.044(1) itself would have conferred jurisdiction upon the trial court over their ballot measure challenges and jurisdiction under ORS 28.010 therefore would have been unnecessary. However, that argument is contrary to the explicit text of ORS 250.044(2), which provides, in part:
“An action under subsection (1) of this section must be within the jurisdiction of circuit courts and must present a justiciable controversy. * * *”
(Emphasis added.) By its terms, subsection (2) of ORS 250.044 indicates that subsection (1) itself does not confer jurisdiction over a ballot measure challenge. Instead, as this court explained in Swett, ORS 250.044(1) only sets out a list of three requirements “respecting when and where a certain class of ballot-measure challenges must be filed.” 333 Or at 605. Therefore, even if plaintiffs had waited for the Secretary of State’s certification of Measure 7 to bring their challenge, they nevertheless would have had to assert jurisdiction under the UDJA (or another appropriate statute, if any). For those reasons, we reject the state’s argument that the trial court lacked subject matter jurisdiction under ORS 28.010.
B. Jurisdiction under ORS 246.910(1)
Ordinarily, our discussion of jurisdiction would end at this point, that is, with our conclusion that the trial court properly assumed jurisdiction under a particular statutory scheme. However, because we conclude, as discussed below, that only two McCall plaintiffs have standing under the UDJA, we must consider the remaining McCall plaintiffs’ alternative theory of jurisdiction under ORS 246.910(1), which concerns challenges to actions by the Secretary of *654State.7 That consideration is necessary, because, if the trial court had jurisdiction under ORS 246.910(1), then any McCall plaintiffs who do not have standing under the UDJA would have the opportunity to assert standing under ORS 246.910(1). See Local No. 290 v. Dept. of Environ. Quality, 323 Or 559, 565, 919 P2d 1168 (1996) (when ruling on standing, court must focus upon wording of particular statute at issue). Accordingly, we now address McCall plaintiffs’ argument under ORS 246.910(1). For the reasons set out below, we conclude that the trial court did not have jurisdiction under that statute.
ORS 246.910(1) provides, in part:
“A person adversely affected by any act or failure to act by the Secretary of State * * * may appeal therefrom to the circuit court for the county in which the act or failure to act occurred * *
In their complaint, McCall plaintiffs specifically allege four acts by the Secretary of State (or his predecessor) that adversely affected them. Three were “decisions that resulted in Measure 7 appearing on the ballot [:] * * * accepting the proposed petition, verifying that the petition contained the requisite number of signatures, and certifying the measure for placement on the ballot.”8 The fourth, deciding to canvass and beginning to canvass the votes for and against Measure 7, occurred after the election and was in progress when plaintiffs filed their actions.9
*655On appeal, the state does not address McCall plaintiffs’ challenge as a challenge to several distinct acts by the Secretary of State as alleged in the complaint. Instead, the state characterizes McCall plaintiffs’ challenge generally as a challenge to the Secretary of State’s initial constitutional evaluation of the proposed initiative petition that ultimately became Measure 7. The state then argues that that challenge is untimely because it was not filed within 60 days of the Secretary of State’s certification of the ballot title, as required by Ellis v. Roberts, 302 Or 6, 725 P2d 886 (1986).10
McCall pláintiffs agree that the Secretary of State’s constitutional evaluation of the proposed initiative petition that became Measure 7 is the “act” at the heart of this challenge. 11 McCall plaintiffs do not contend that they were adversely affected by the Secretary of State’s other acts set out above; they also do not allege that any of those acts were improper per se.12 Rather, they contend that they were adversely affected by the acts identified in their complaint *656only insofar as those acts were steps toward the implementation of a ballot measure that, according to McCall plaintiffs, violates multiple form-of-adoption requirements of the Oregon Constitution.
Despite their agreement that the Secretary of State’s constitutional evaluation of the proposed initiative petition that became Measure 7 is the act truly at issue here, McCall plaintiffs nevertheless argue that Ellis does not apply to their challenge. They argue that the 60-day deadline set out in Ellis applies to only challenges under ORS 246.910(1) that seek to keep a measure off the ballot, that is, to challenges brought before the election. Because they brought their challenge after the election, McCall plaintiffs argue, they are not constrained by the 60-day deadline.
We disagree. Respecting a challenge under ORS 246.910(1) to the Secretary of State’s constitutional evaluation of a proposed initiative measure, Ellis sets out a 60-day deadline, following certification of a ballot title. 302 Or at 19. As applicable to this case, that deadline expired in June 1999, 60 days after the Attorney General certified the ballot title for the initiative petition that ultimately became Measure 7. Consequently, the time for plaintiffs to have challenged the Secretary of State’s constitutional evaluation of Measure 7, the underpinning of jurisdiction under ORS 246.910(1) for purposes of this case, long has passed.
McCall plaintiffs argue, as noted above, that Ellis— specifically, its 60-day deadline — should apply to only challenges brought before the election. That argument misses the broader point, that is, that the very nature of their challenge is a pre-election challenge to a pre-election Secretary of State decision. As this court explained in Ellis, 302 Or at 17:
“There is a season for each kind of challenge to the Secretary of State’s administration of election laws, whether as to the ballot title, the signature gathering process [,] or constitutional evaluation. * * * The Secretary of State makes— or fails to make — the constitutional decision at the outset. * * * Later actions, such as acceptance of a ballot title from the Attorney General, verification of signatures and certification, do not call for [the Secretary of State] to reassess the original constitutional evaluation that is supposed to be *657the predicate for placing the entire initiative machinery in operation. It is either done or not at this initial stage. The period of reasonable time commences then.”
(Citations omitted.) The fact that McCall plaintiffs filed their action after the election does not save their challenge for jurisdictional purposes under ORS 246.910(1): The “season” for their challenge occurred before the election, within 60 days after the Attorney General certified the ballot title.13 We conclude that the trial court did not have jurisdiction to hear McCall plaintiffs’ challenge under ORS 246.910(1).14
III. STANDING
A. Legal Principles Respecting Standing
Having determined that the trial court appropriately assumed jurisdiction under the UDJA, we now turn to intervenor’s argument that no plaintiff in either action had standing to challenge Measure 7 under that statutory scheme. Although we agree with intervenor respecting three McCall plaintiffs (McCall, MacPherson, and Swaim) and two League plaintiffs (individual plaintiffs Stein and Katz), we conclude that plaintiffs Lewis and Tipperman, among McCall plaintiffs, and the remaining League plaintiffs (local government plaintiffs) have standing to challenge Measure 7.
*658The requirements for standing under the UDJA are set out in ORS 28.020:
“Any person * * * whose rights, status or other legal relations are affected by a constitution, statute, [or] municipal charter * * * may have determined any question of construction or validity arising under any such * * * constitution, statute, [or] municipal charter * * * and obtain a declaration of rights, status or other legal relations thereunder.”
Additionally, ORS 28.130 defines the word “person” as used in the UDJA
“* * * mean any person, partnership, joint stock company, unincorporated association or society, or municipal or other corporation of any character whatsoever.”
Thus, to establish standing, a plaintiff must show that the plaintiff is a “person” as defined in ORS 28.130 and that the plaintiffs “rights, status or other legal relations are affected” by the law or enactment at issue.
In identifying the requisite “[e]ffect[ ]” to establish standing under ORS 28.020, this court has held that a plaintiff must show some injury or other impact upon a legally recognized interest beyond an abstract interest in the correct application or the validity of a law. Eckles v. State of Oregon, 306 Or 380, 385, 760 P2d 846 (1988). In addition, the plaintiffs showing of that injury or other impact must not be “too speculative.” Gruber v. Lincoln Hospital District, 285 Or 3, 7, 588 P2d 1281 (1979).
With those requirements in mind, we turn to the evidence of injury or other impact that plaintiffs offered before the trial court. Because we are reviewing a grant of summary judgment, we view the facts and all reasonable inferences that may be drawn from them in favor of the nonmoving parties — in this case, the state and intervenor. Robinson v. Lamb’s Wilsonville Thriftway, 332 Or 453, 455, 31 P3d 421 (2001).
B. McCall Plaintiffs
McCall plaintiffs’ complaint included the following allegations that are relevant to our discussion:
*659“Plaintiffs are taxpayers and registered voters in Oregon. They voted in the November 7, 2000, general election. Some or all of them own land in areas that are subject to regulations restricting the use of private real property.
“Plaintiffs Swaim and Lewis are the Mayors of Salem and Jacksonville, respectively. Their official duties include deciding whether and how to enforce regulations that affect the value and use of private real property.”
McCall plaintiffs also attached, as “Exhibit A” of their complaint, a copy of a page of the voters’ pamphlet that included the text of Measure 7, its accompanying ballot title, and a brief estimate of financial impact.
McCall plaintiffs argue that they all have standing as landowners because they oppose the increased development that Measure 7 would bring about. However, on summary judgment, McCall plaintiffs McCall, MacPherson, and Swaim rested upon the allegations of their complaint, set out above, and failed to allege or show that Measure 7 would lead to increased development, how it would do so, and how, specifically, that increased development would affect them as landowners. The only specific impact upon plaintiffs McCall, MacPherson, and Swaim as landowners that we can discern from the text of Measure 7 is that, generally speaking, landowners would be compensated for — or arguably might avoid altogether — certain governmental regulations of their private property. That impact is not sufficient to establish standing under ORS 28.020, because it is not sufficiently adverse, a quality that is central to the question of standing in any context. See People for Ethical Treatment v. Inst. Animal Care, 312 Or 95, 101, 817 P2d 1299 (1991) (so stating).15
*660By contrast, McCall plaintiffs Lewis and Tipperman submitted uncontroverted affidavits in which they offered details concerning how, specifically, Measure 7 would affect them.16 In his affidavit, Lewis avers that (1) he is the Mayor of Jacksonville and owns property there; (2) he has made efforts — to date, successful — to prevent the conditional use of forest resource land outside Jacksonville as an aggregate mine; (3) he has been named as a defendant in a federal complaint filed by the owner of the forest resource land; (4) the forest resource landowner alleged in her federal complaint that, under Measure 7, she would be entitled to $50 million if Jackson County prevents her from using her land as an aggregate mine; (5) as a result of the litigation, Jacksonville is reconsidering its opposition to the aggregate mine; and (6) if the forest resource landowner succeeds in obtaining permission to mine her property, then the value of real estate in Jacksonville, including his own, will decrease.
Plaintiff Tipperman, a rancher who owns a large timber and cattle ranch in Union County, avers as follows in his affidavit:
“In my opinion, if the county or state were to repeal or ‘waive’ or otherwise not enforce land use law, to avoid liability for compensation under Measure 7, some surrounding and nearby parcels of land would be developed for residential and possibly commercial use. That would diminish the value of my farm, because those other uses and ranching are generally not compatible in close proximity to one another. Such development would also interfere with my ability to continue ranching and * * * would thus jeopardize a portion of my income.
“If Measure 7 is adopted, the value and utility of [my] * * * ranch will be significantly diminished. * * * [R]ural *661residences and hobby farms * * * will sprout on adjoining tracts of land, bringing dogs which will harass the livestock and wildlife on the [r]anch, and unending trespassing and poaching by my new found neighbors and their friends. There will be other adverse consequences including reduction of stream flows (which supply water for our livestock and fish) which are already at precariously low levels during the Summer and early Fall.”
Although the consequences that plaintiffs Lewis and Tipperman anticipate are not certain to result from the implementation of Measure 7, they are plausible, concrete ramifications. Both plaintiffs Lewis and Tipperman introduced evidence that shows how Measure 7 would lead to increased development and how, specifically, that increased development would injure them. Because plaintiffs Lewis and Tipperman established that Measure 7 would affect their rights, status, or legal relations, we conclude that they have standing to challenge Measure 7 under ORS 28.020.
C. League Plaintiffs
League plaintiffs’ complaint sets out the following allegations respecting standing:
“Plaintiffs City of Eugene, City of Portland, Junction City, City of Veneta, and City of Beaverton are municipal corporations with home rule powers granted by the Oregon Constitution. Plaintiffs Multnomah County, Benton County and Washington County are counties with home rule powers granted by the Oregon Constitution. Plaintiffs * * * Stein and * * * Katz are citizens of the State of Oregon, and electors and taxpayers.”
League plaintiffs also attached the text of Measure 7, as well as its accompanying ballot title and a brief estimate of financial impact, as “Exhibit A” of their complaint. The estimate of financial impact provided:
“Direct costs to the state are estimated to be $1.6 billion per year. Local government direct costs are estimated to be $3.8 billion per year.”
League plaintiffs did not submit affidavits in further support of their standing under ORS 28.020; consequently, the allegations in their complaint constituted the only material *662respecting standing before the trial court on summary judgment.
As to the League plaintiffs Stein and Katz, as with McCall plaintiffs McCall, MacPherson, and Swaim, neither the allegations in the complaint nor the attached exhibit demonstrates how Measure 7 would affect them. Accordingly, they lack standing to bring this challenge.
The local government plaintiffs consist of municipal corporation (city) plaintiffs and county plaintiffs. In respect of the city plaintiffs, the UDJA specifically treats municipal (and all other) corporations as “persons” for purposes of the act. ORS 28.130. Accordingly, a city, like any person, has standing to bring an action under the UDJA if that city’s “rights, status or other legal relations are affected.” ORS 28.010. In respect of the county plaintiffs, this court has recognized that declaratory relief is available to counties under the UDJA. See Tillamook Co. v. State Board of Forestry, 302 Or 404, 416, 730 P2d 1214 (1986) (recognizing county’s standing to bring declaratory judgment action against state).
When we examine the text of Measure 7 (Exhibit A of League plaintiffs’ complaint), specifically, subsection (a), we see that, because cities and counties are forms of “local government” that “pass[ ] or enforce [ ] * * * regulation [s] that restrict[ ] the use of private real property,” Measure 7 will have a fiscal impact upon any city or county each time that the city or county chooses to regulate real property in a manner that gives rise to a Measure 7 claim. That impact — officially estimated as a cost of 3.8 billion dollars to local governments generally — is not abstract. Thus, despite its few specific allegations, League plaintiffs’ complaint demonstrates that Measure 7 will have a fiscal impact upon the local government plaintiffs. That impact is sufficient to show that Measure 7 will “affect [ ]” those plaintiffs’ “legal relations” within the meaning of ORS 28.020. Accordingly, the local government plaintiffs have standing to challenge Measure 7 under the UDJA.17
*663IV. RIPENESS
The final issue that we must address before turning to the merits is the ripeness of the controversy. Intervenor argues that the controversy is hot ripe because the Secretary of State has not yet completed canvassing the votes for and against Measure 7, and the Governor has not yet proclaimed that the measure has passed. However, the record includes uncontroverted evidence (the official county abstracts and the unofficial vote tally) that shows that a majority of the voters approved Measure 7 at the November 2000 general election. According to that evidence, the Secretary of State’s canvass of the votes will not alter that result. Under those circumstances, plaintiffs’18 challenge to Measure 7 is not premature, because the ultimate, official result clearly can be forecasted. See Brown v. Oregon State Bar, 293 Or 446, 449, 648 P2d 1289 (1982) (ORS chapter 28 requires controversy that “involve [s] present facts as opposed to a dispute which is based on future events of a hypothetical nature” (emphasis added)); Hale v. Fireman’s Fund Ins. Co. et al, 209 Or 99, 103-04, 302 P2d 1010 (1956) (request for declaratory relief not ripe if contingent upon happening of event that cannot be forecast and may never take place). Accordingly, we conclude that this controversy is ripe. We now turn to the merits.
V. ARTICLE XVII, SECTION 1
A. Legal Principles Respecting Article XVII, Section 1, and Parties’ Contentions
As noted earlier, the trial court concluded that Measure 7 violated the separate-vote requirement of Article XVII, section 1, which provides, in part:
*664“When two or more amendments shall be submitted * * * to the voters of this state at the same election, they shall be so submitted that each amendment shall be voted on separately.”
The trial court relied, in part, upon Armatta v. Kitzhaber, 327 Or 250, 277, 959 P2d 49 (1998), in which this court concluded that, to determine whether a measure denominated as a single amendment actually contained “two or more amendments” for constitutional purposes, a court must determine “whether, if adopted, the proposal would make two or more changes to the constitution that are substantive and that are not closely related.” This court recently reaffirmed that holding in Lehman v. Bradbury, 333 Or 231, 242, 37 P3d 989 (2002).
The state and intervenor contend, at the outset, that Measure 7 makes only one substantive “change” under the first part of the Armatta inquiry and, consequently, that further analysis under Article XVII, section 1, is unnecessary. Alternatively, the state and intervenor contend that, even if Measure 7 makes more than one substantive change to the Oregon Constitution, those changes are “closely related.” In response, plaintiffs contend that the trial court correctly concluded that Measure 7 contravened the separate-vote requirement because the measure made multiple, substantive changes to the Oregon Constitution that were not closely related.
B. Changes Made by Measure 7
We begin by addressing certain of the substantive changes that plaintiffs contend that Measure 7 makes to the Oregon Constitution. As noted above, plaintiffs first contend that, by its express terms, Measure 7 substantively changes Article I, section 18. The state and intervenor agree, as do we. The parties disagree, however, concerning the effect of Measure 7 upon other parts of the Oregon Constitution, including Article I, section 8. Below, we first briefly summarize the effect of Measure 7 upon Article I, section 18, and then turn to the effect that Measure 7 has upon Article I, section 8.19
*6651. Article I, Section 18
Article I, section 18, provides, in part:
“Private property shall not be taken for public use * * * without just compensation; nor except in the case of the state, without such compensation first assessed and tendered; provided, that the use of all roads, ways and waterways necessary to promote the transportation of the raw products of mine or farm or forest or water for beneficial use or drainage is necessary to the development and welfare of the state and is declared a public use.”
That provision requires payment of “just compensation” for a variety of governmental actions that result in the “taking” of private property for public use, including “regulatory” takings by way of application or enforcement of regulations with certain economic ramifications. Boise Cascade Corp. v. Board of Forestry, 325 Or 185, 197-98, 935 P2d 411 (1997).
Measure 7 explicitly amends Article I, section 18, as follows:
“BE IT ENACTED BY THE PEOPLE OF THE STATE OF OREGON:
“THE CONSTITUTION OF THE STATE OF OREGON IS AMENDED BY ADDING THE FOLLOWING SUBSECTIONS TO SECTION 18 OF ARTICLE I:
“(a) If the state, a political subdivision of the state, or a local government passes or enforces a regulation that restricts the use of private real property, and the restriction has the effect of reducing the value of a property upon which the restriction is imposed; the property owner shall be paid just compensation equal to the reduction in the fair market value of the property.
*666“(b) For purposes of this section, adoption or enforcement of historically and commonly recognized nuisance laws shall not be deemed to have caused a reduction in the value of a property. The phrase “historically and commonly recognized nuisance laws’ shall be narrowly construed in favor of a finding that just compensation is required under this section.
“(c) A regulating entity may impose, to the minimum extent required, a regulation to implement a requirement of federal law without payment of compensation under this section. Nothing in this 2000 Amendment shall require compensation due to a government regulation prohibiting the use of a property for the purpose of selling pornography, performing nude dancing, selling alcoholic beverages or other controlled substances, or operating a casino or gaming parlor.
“(d) Compensation shall be due the property owner if the regulation was adopted, first enforced or applied after the current owner of the property became the owner, and continues to apply to the property 90 days after the owner applies for compensation under this section.
“(e) Definitions: For purposes of this section, ‘regulation’ shall include any law, rule, ordinance, resolution, goal, or other enforceable enactment of government; ‘real property1 shall include any structure built or sited on the property, aggregate and other removable minerals, and any forest product or other crop grown on the property; ‘reduction in the fair market value’ shall mean the difference in the fair market value of the property before and after application of the regulation, and shall include the net cost to the landowner of an affirmative obligation to protect, provide, or preserve wildlife habitat, natural areas, wetlands, ecosystems, scenery, open space, historical, archaeological or cultural resources, or low income housing; and ‘just compensation’ shall include, if a claim for compensation is denied or not fully paid within 90 days of filing, reasonable attorney fees and expenses necessary to collect the compensation.
“(f) If any phrase, clause, or part of this section is found to be invalid by a court of competent jurisdiction, the *667remaining phrases, clauses and parts shall remain in full force and effect.”
(Emphasis added.) As its text demonstrates, Measure 7 explicitly changes Article I, section 18, in a number of ways. Most significantly, Article I, section 18, currently requires payment of just compensation only when a property owner demonstrates that a governmental regulation has “deprive [d] the owner of all economically viable use of the property. * * * If the owner has some substantial beneficial use of the property remaining, then the owner fails to meet the test.” Boise Cascade Corp., 325 Or at 197-98 (internal quotation marks and citations omitted; emphasis added); see also Dodd v. Hood River County, 317 Or 172, 181-82, 855 P2d 608 (1993) (to same effect). After amendment by Measure 7, Article I, section 18, would require payment of just compensation for any reduction in the value of private real property resulting from the enforcement of a restrictive regulation, even that which falls short of the standard set out in Boise Cascade Corp. and Dodd.
Although Measure 7 changes Article I, section 18, in other ways, and although the parties disagree regarding the extent and ramifications of such changes, we need not discuss such changes here. That is so, because we conclude below that Measure 7 also implicitly changes Article I, section 8, in a substantive way and that the explicit, substantive change to Article I, section 18, discussed above, is not closely related to the implicit change that Measure 7 makes to Article I, section 8. Accordingly, the number of other changes that Measure 7 makes to Article I, section 18, has no bearing upon our decision in this case. See Swett, 333 Or at 607 (because court addressed two substantive changes that were not closely related, unnecessary to discuss other changes made by measure at issue).20 We turn to our analysis of the effect of Measure 7 upon Article I, section 8.
*6682. Article I, Section 8
Plaintiffs contend that subsection (c) of Measure 7 changes Article I, section 8. We address that argument by first turning again to the text of Measure 7.
As noted above, in subsection (a), Measure 7 requires payment of just compensation for restrictive regulations that reduce the value of private real property. Subsection (c) of Measure 7, however, creates the following exception to the just-compensation requirement set out in subsection (a):
“Nothing in this 2000 Amendment shall require compensation due to a government regulation prohibiting the use of a property for the purpose of selling pornography, performing nude dancing, selling alcoholic beverages or other controlled substances, or operating a casino or gaming parlor.”
In other words, subsection (c) permits the state and local governments not to pay a claim that otherwise would qualify under subsection (a), if that claim is made in response to a regulation that forbids using the subject property for one of the enumerated purposes. By its terms, then, subsection (c) permits the state and local governments not to pay just compensation for regulations that explicitly prohibit using property for those purposes, even if such regulations reduce property value under subsection (a).
Plaintiffs contend that, because subsection (c) permits the state or a local government not to pay just compensation to private real property owners whose property decreases in value because of a regulation prohibiting the use of property for, among other uses, the purpose of selling pornography, Measure 7 changes the right to free expression currently guaranteed by Article I, section 8. The state and intervenor respond that subsection (c) merely creates an exception to the right to just compensation set out in subsection (a) and, viewed in that way, does not change rights currently guaranteed by Article I, section 8. Alternatively, inter-venor contends that, if subsection (c) does operate to prevent certain property owners from receiving payment of just compensation, such a scheme never could be enforced, because it would not be permitted under Article I, section 8. Therefore, *669in intervenor’s view, Measure 7 effectively could not “change” Article I, section 8, because that constitutional provision would prevent subsection (c) from becoming effective in the first instance. As explained below, we agree with plaintiffs.
Article I, section 8, in place since statehood, provides, in part:
“No law shall be passed restraining the free expression of opinion, or restricting the right to speak, write, or print freely on any subject whatever [.]”
As this court explained in City of Portland v. Tidyman, 306 Or 174, 179, 759 P2d 242 (1988), Article I, section 8, “forbids the enactment of a law directed in terms against any subject of speech, writing, or printing,” unless the communication in question falls within “a well-established historical exception that the constitutional guarantees demonstrably were not meant to displace.”
There is no suggestion in the text of Measure 7 that the term “pornography’ is used in other than its ordinary sense. So understood, it is clear that pornography is one form of “speech, writing, or printing.” Tidyman, 306 Or at 179. Further, this court has determined that restrictions upon sexually explicit and obscene expression involving adults— such as many forms of pornography — do not fit within any historical exception. State v. Henry, 302 Or 510, 523, 732 P2d 9 (1987). Therefore, the term “pornography,” as used in subsection (c), includes some forms of expression that, no matter how offensive to many people, are protected under Article I, section 8.
The state and intervenor do not quarrel with the foregoing statement of Oregon constitutional law. Neither do they disagree that the use of property “for the purpose of selling pornography,” as described in subsection (c), implicates the right of free expression. Instead, as noted, the state and intervenor argue that subsection (c) does not change that right because it does not take away any benefit that property owners who use their property to sell pornography currently enjoy. That is, such property owners would not be entitled to just compensation for the type of regulation described in subsection (c) today, and they would not be entitled to it under *670Measure 7. Therefore, according to the state and intervenor, Measure 7 would not change those owners’ right of free expression.
The state’s and intervenor’s argument mistakenly focuses upon whether property owners who use their property to sell pornography actually would lose money under Measure 7. That is not the question. The question is whether those owners would experience any change in the constitutional right to free expression to which they currently are entitled under Article I, section 8. We turn to that question now.
As we have explained, as it currently operates, Article I, section 8, prohibits the state or a local government from enacting a law that is directed against the content of constitutionally protected expression. Tidyman, 306 Or at 179. Thus, the state or a local government may not enact a law that is directed against the selling of pornography because it is pornography. Id. However, the protection afforded by Article I, section 8, does not end with the protection from regulations that explicitly target expression. As this court explained in City of Eugene v. Miller, 318 Or 480, 491, 871 P2d 454 (1994), freedom of expression as guaranteed by Article I, section 8, also means that the state or a local government may not treat those who sell expressive material “more restrictively” than those who sell other merchandise. Because Miller is crucial to understanding the scope of the freedom of expression that Article I, section 8, guarantees, we briefly discuss that case here.
Miller concerned a bookseller’s challenge to a city ordinance that prohibited the sale of most forms of merchandise on city sidewalks, except (by license) the sale of “food, beverages, flowers or balloons.” 318 Or at 483. On its face, the ordinance targeted neither expression generally nor any particular type of expression. Stated differently, in the words of Tidyman, 306 Or at 179, the ordinance was not explicitly “directed in terms against any subject of speech.” However, the ordinance operated to restrict the bookseller — someone who sold expressive material protected under Article I, section 8 — to a greater extent than it did those who sold food, *671beverages, flowers, and balloons. That restriction, this court held, violated Article I, section 8. The court explained:
“So long as the city chooses to make its sidewalks available for some general commercial activity * * *, it may not treat a vendor of expressive material more restrictively than vendors of other merchandise * *
318 Or at 491 (emphasis in original).
Miller demonstrates that a governmental burden upon free expression is one type of “restrain [t]” of expression that Article I, section 8, prohibits. It is equally clear under Miller that a governmental enactment that allows some persons to participate in a certain activity, but prohibits others engaged in expression from participating in that same activity, constitutes a prohibited burden upon expression.21 It follows that a governmental scheme that requires payment to some persons, but not others engaged in protected expression, also constitutes a burden that Article I, section 8, prohibits. For that reason, today, if the state or a local government is required to offer a benefit to some property owners, it may not, under Article I, section 8, choose not to offer that same benefit to another property owner because that latter owner engages in a particular type of expressive activity.22
Under Measure 7, by contrast, the state and local governments explicitly would be permitted to do just that, *672i.e., they could decline to pay just compensation under Article I, section 18, to a property owner because that owner engages in a particular type of expressive activity, namely, the sale of some forms of pornography. Stated differently, subsection (c) operates to permit the state and local governments to choose not to pay such a property owner, unless that owner were to change the content of the expressive material sold on the property in question — essentially placing a price tag upon the property owner’s right of free expression. Consequently, subsection (c) changes — indeed, limits — the scope of the rights currently guaranteed by Article I, section 8. For that reason, we reject the state’s and intervenor’s argument that subsection (c) does not constitute a constitutional “change” for purposes of our separate-vote analysis.
Intervenor also contends that, because regulations directed toward constitutionally protected expression — such as those that, under subsection (c), would “prohibit [ ] the use of a property for the purpose of selling pornography” — are impermissible under Article I, section 8, the exception to the just-compensation requirement set out in subsection (c) never could be enforced and, consequently, cannot be deemed a constitutional “change” for purposes of Article XVII, section 1. Again, we disagree.
We first note that, in Tidyman, 306 Or at 185, 188, 190-91, this court left open the possibility that a regulation ostensibly directed against expression might pass constitutional muster, provided that such a regulation in fact was directed toward negative effects sought to be prevented and also specified the harm that otherwise would arise if the regulation were not adopted. Consequently, although this court has not yet decided a case involving such a regulation, it is possible that a governmental entity, today, could craft a regulation that “prohibit [s] the use of a property for the purpose of selling pornography” without running afoul of Article I, section 8.
That said, we disagree with intervenor’s theory that a constitutional change that never might be enforced is not a “change” for separate-vote purposes. Subsection (c), as of the moment of its passage, carves out an explicit constitutional *673exception to the protection that Article I, section 8, now provides. Stated differently, subsection (c) sets out a circumstance, effective as of the effective date of Measure 7, in which the state and local governments constitutionally must provide a benefit to some property owners, but may decline to offer it to other property owners who use their property to sell a type of expressive material that is protected under Article I, section 8. Regardless of whether the state or a local government ever chooses to take advantage of the exception set out in subsection (c), that exception nevertheless is a “change” to the scope of the rights currently guaranteed by Article I, section 8, for pin-poses of our separate-vote analysis in this case. See generally Lehman, 333 Or at 243 n 8 (fact that one constitutional change made by measure at issue was prohibited by United States Constitution did not affect court’s separate-vote analysis).
In sum, although the text of Measure 7 purports to change only Article I, section 18, its inclusion of the exception set out in subsection (c) nonetheless changes rights currently guaranteed by Article I, section 8. See generally Coalition for Equit. School Fund. v. State of Oregon, 311 Or 300, 309, 811 P2d 116 (1991) (“When a party argues that a general constitutional provision forbids the state from doing something, the argument may be answered by a later-adopted constitutional provision that allows the state to do that very thing.”). For those reasons, we conclude that, as written, Measure 7 substantively changes two existing constitutional provisions: Article I, section 18 (takings), and Article I, section 8 (freedom of expression).
C. Analysis of Measure 7 under Article XVII, Section 1
As noted above, our inquiry under Armatta, 327 Or at 277, is to determine whether Measure 7 makes “two or more changes” to the Oregon Constitution that are “substantive” and are not “closely related.” The foregoing analysis establishes that Measure 7 makes at least two substantive changes to the existing constitution, that is, a change to the requirements for payment of just compensation to property owners under Article I, section 18, and a separate change *674respecting laws restraining expression under Article I, section 8. We turn, then, to application of Armatta’s “closely related” prong.
In Lehman, 333 Or at 246, this court offered a further explanation as to application of the phrase “closely related” from Armatta:
“* * * First, we examine the relationship among the constitutional provisions that the measure affects, both explicitly and implicitly. If the affected provisions of the existing constitution themselves are not related, then it is likely that changes to those provisions will offend the separate-vote requirement. * * * [T]he fact that a proposed amendment asks the people, in one vote, substantively to change multiple provisions of the Oregon Constitution that are not themselves related is one indication that the proposed amendment might violate the separate-vote requirement.
“Next, we must consider the constitutional changes themselves. * * * If they are closely related, the measure under consideration survives scrutiny under Article XVII, section 1. If they are not, it does not.”
Following that approach, we proceed to analyze the relationship between the two existing constitutional provisions affected by Measure 7, as well as the relationship between the substantive constitutional changes that the measure effects.
As to the constitutional provisions that Measure 7 affects — Article I, section 18, and Article I, section 8 — we have no difficulty concluding that, other than their placement in the Bill of Rights, those provisions bear no relation to each other. Article I, section 18, provides a right to “just compensation” to private property owners whose property is taken for public use. Article I, section 8, by contrast, expressly precludes, as to any person, any restriction upon the “free expression of opinion,” as well as upon “the right to speak, write, or print freely on any subject whatever.” Those two constitutional provisions involve “separate constitutional rights, granted to different groups of persons.” Armatta, 327 Or at 283. That lack of relationship “is a strong indication that those provisions are not ‘related’ for purposes *675of the separate-vote requirement.” Lehman, 333 Or at 246 n 9.
Turning to the constitutional changes themselves, we conclude that the change that Measure 7 makes to Article I, section 18, that is, an expanded just-compensation requirement for restrictive regulations that reduce the value of private real property, is not closely related to the change that it makes to Article I, section 8, that is, creating an exception to the historical requirement that laws cannot treat those engaged in expressive activity “more restrictively” than others not engaged in expressive activity, Miller, 318 Or at 491. The change to Article I, section 18, generally concerns the ability of a real property owner to obtain just compensation for enforcement of certain regulations — indeed, that change generally expands the rights of property owners vis-a-vis the government in that regard. By contrast, the change that Measure 7 makes to Article I, section 8, operates to limit the rights of certain property owners, vis-a-vis other property owners, based upon the content of the expressive material sold on their property. More notably, the change that Measure 7 makes to Article I, section 8, carves out an exception to the fundamental principle that no law shall restrict expression “on any subject whatever.” See Henry, 302 Or at 515 (Article I, section 8, broadly covers “any expression of opinion” on “any subject whatever,” without exception). By incorporating both types of substantive changes that are not closely related, Measure 7 makes “two or more amendments” to the Oregon Constitution that the voters were required to have voted upon separately.
D. Measure 7 is Invalid in its Entirety
As this court explained in Armatta, 327 Or at 284, and again in Lehman, 333 Or at 250-51, a proposed constitutional amendment must be adopted in compliance with constitutional requirements:
“It is a long-standing principle of law that a proposed constitutional amendment must be adopted in compliance with the procedures set forth in the Oregon Constitution:
“ ‘The provisions of the constitution for its own amendment are mandatory, and must be strictly observed. A *676failure in this respect will be fatal to a proposed amendment, notwithstanding it may have been submitted to and ratified and approved by the people. The constitutional provisions are as binding upon the people as upon the legislative assembly, and the people cannot give legal effect to an amendment which was submitted in disregard of the limitations imposed by the constitution ***.*** * * an attempt is made to amend an existing constitution, its every requirement regarding its own amendment must be substantially observed, and the omission of any one will be fatal to the amendment. The constitution is the supreme law of the land, binding upon all, and can no more be disregarded in the manner of its own amendment than in any other respect. As long as it remains, its provisions must be observed.’ ”
Armatta, 327 Or at 284-85 (quoting Kadderly v. Portland, 44 Or 118, 135-36, 74 P 710, on reh’g, 75 P 222 (1904)) (emphasis and ellipses in Armatta). Accordingly, because Measure 7 was not adopted in compliance with the requirements of Article XVII, section 1, we hold that it is void in its entirety.
VI. ATTORNEY FEES
Finally, we address the issue of attorney fees. As noted at the outset of this opinion, McCall plaintiffs, but not League plaintiffs, specifically requested attorney fees in their complaint. After the trial court entered its ruling below, McCall plaintiffs petitioned for attorney fees, and the state objected. From our review of the record, it appears that the trial court never ruled on plaintiffs’ petition or on the state’s objection. For that reason, and because the issue of attorney fees further will involve consideration of our holding that only plaintiffs Lewis and Tipperman sufficiently alleged standing in the McCall case, we remand the case to the trial court for further proceedings.
VII. CONCLUSION
In sum, we hold that (1) the trial court did not err in assuming jurisdiction under the UDJA; (2) the trial court did not have jurisdiction under ORS 246.910(1); (3) plaintiffs Lewis, Tipperman, and the local government League plaintiffs, but not the remaining McCall plaintiffs or League plaintiffs, established standing for purposes of the UDJA; (4) the *677controversy is ripe for adjudication; (5) Measure 7 encompasses two amendments to the Oregon Constitution in violation of Article XVII, section 1, and, therefore, is void in its entirety; and (6) the case must be remanded to the trial court.
The judgment of the circuit court is affirmed in part and reversed in part, and the case is remanded to the circuit court for further proceedings.
Both actions name the State of Oregon, Governor Kitzhaber, and Secretary of State Bradbury as defendants. We refer to all three defendants collectively as “the state” throughout this opinion.
As explained below, although the Secretary of State has not yet completed canvassing the votes on Measure 7, the official county election results contained in the record demonstrate that a majority of voters approved the measure.
McCall plaintiffs also contended that Measure 7 was adopted in violation of Article IV, section l(2)(d), which sets out a “full-text” requirement for initiative petitions and a “single-subject” requirement for laws and constitutional amendments proposed by initiative petition, and Article XVII, section 2, which sets out the process for adopting constitutional revisions. McCall plaintiffs later contended before the trial court that submission of Measure 7 also violated ORS 251.195, which sets out voters’ pamphlet requirements for proposed constitutional *650amendments, thereby also violating Article IV, section l(4)(b), which requires that initiatives be submitted according to laws not inconsistent with that section.
The trial court concluded that all plaintiffs (in both actions) except plaintiff League of Oregon Cities had standing under ORS 28.020. League plaintiffs, collectively, do not challenge that conclusion on appeal; accordingly, future references to “League plaintiffs” in this opinion do not include plaintiff League of Oregon Cities.
The trial court also concluded that Measure 7 violated the full-text requirement of Article IV, section l(2)(d); however, the court rejected plaintiffs’ arguments respecting single-subject and revision, and did not rule on McCall plaintiffs’ argument respecting submission according to election laws.
On appeal, neither set of plaintiffs challenges the trial court’s conclusion respecting the single-subject requirement. All other matters pending before the trial court discussed above, with the exception of attorney fees, have been raised on appeal. Because we resolve this case based upon the separate-vote requirement, we do not address the remaining constitutional issues.
ORS 250.044(1) provides, in part:
“An action that challenges the constitutionality of a measure initiated by the people * * * must be commenced in the Circuit Court for Marion County if:
“(a) The action is filed by a plaintiff asserting a claim for relief that challenges the constitutionality of * * * an amendment to the Oregon Constitution initiated by the people * * * under section 1 (1) to (4), Article IV of the Oregon Constitution;
“(b) The action is commenced on or after the date that the Secretary of State certifies that the challenged measure has been adopted by the electors and within 180 days after the effective date of the measure; and
“(c) The action may not be commenced in the Oregon Tax Court.”
We also conclude below that two League plaintiffs, Katz and Stein, lack standing under ORS 28.020. However, League plaintiffs did not argue alternatively that the trial court had jurisdiction under ORS 246.910(1).
We take judicial notice of the following facts: (1) Measure 7 began as Initiative Petition 46 (2000); (2) the petition originally was filed with the Secretary of State on March 10,1999; (3) the Attorney General certified the ballot title on April 9,1999; (4) the Secretary of State approved the proposed initiative for circulation on May 28, 1999; and (5) the Secretary of State certified the ballot measure (as Measure 7) on July 26,2000. See generally OEC 201(f) (judicial notice may be taken “at any stage of the proceedings”); Leo v. Keisling, 327 Or 556, 559 n 1, 964 P2d 1023 (1998) (taking judicial notice of earlier elections activity surrounding ballot measure at issue).
All McCall plaintiffs also alleged that they were registered voters. That allegation, together with those plaintiffs’ opposition to Measure 7, was sufficient to establish that they were “person[s] adversely affected” by an action of the Secretary of State, as ORS 246.910(1) requires. See Ellis v. Roberts, 302 Or 6, 10-11, 725 P2d 886 (1986) (“adversely affected” requirement of ORS 246.910(1) means that *655any registered voter can file action challenging Secretary of State election ruling). We contrast that requirement with ORS 28.020, discussed below, which requires for purposes of the UD JA that a person’s “rights, status, or other legal relations” be affected “by a constitution, statute, [or] municipal charter.”
Intervenor generally argues that no challenge upon these grounds may be brought under ORS 246.910(1) after the general election. Our discussion below, addressing the state’s similar, but more specific, argument, disposes of intervenor’s argument.
At the summary judgment hearing, counsel for McCall plaintiffs told the trial court that the issue was “whether or not [Measure 7] was properly on the ballot.”
This court has held that the Secretary of State has the duty to examine an initiative petition for compliance with the single-subject requirement of Article IV, section l(2)(d), of the Oregon Constitution and to refuse to accept those that violate the rule. OEA v. Roberts, 301 Or 228, 235, 721 P2d 833 (1986). The parties assume that, in addition to that duly, the Secretary of State has the duty to examine an initiative petition for compliance with other form-of-adoption requirements of the Oregon Constitution, including the “full-text” requirement of Article IV, section 1(d), the “separate-vote” requirement of Article XVII, section 1, and the constitutional revision requirements of Article XVII, section 2. Because there is no dispute in this case about the extent of the Secretary of State’s duty to review an initiative petition, we assume without deciding that that duty includes the duty to review such a measure for compliance with all other constitutional provisions at issue in this case.
For example, McCall plaintiffs do not argue that the Secretary of State was canvassing the votes improperly.
Contrary to the assertion by the dissent, our holding does not in any way restrict a voter’s ability, under ORS 246.910(1), to challenge any act or failure to act by the Secretary of State. 334 Or at 684 (Durham, J., concurring in part and dissenting in part). Neither do we “confine such challenges solely to the Secretary of State’s first purported exercise of authority.” Id. at 691 (emphasis in original). A voter simply must bring a challenge to the act at issue by the Secretary of State in a timely fashion in relation to when the Secretary of State acted. A voter may not bring such a challenge under ORS 246.910(1) more than 18 months later, as McCall plaintiffs did in this case.
We note that, in State ex rel Keisling v. Norblad, 317 Or 615, 629, 860 P2d 241 (1993), this court referred to the type of challenge at issue in Ellis as a “preelection challenge to the election process.” That description was accurate, but was vulnerable to the interpretation that McCall plaintiffs give it in this case: Because Ellis concerned the timeliness of “pre-election” challenges only, “post-election” challenges do not have any time constraints. As discussed above, we reject that argument. Both the challenge at issue in Ellis and the challenge at issue here are, at bottom, challenges to the Secretary of State’s pre-election constitutional evaluation of a proposed initiative petition.
McCall plaintiffs McCall, MacPherson, and Swaim also argue that they have standing as taxpayers and as voters; plaintiff Swaim further argues that he has standing as a “public official” as described by the Court of Appeals in Multnomah County v. Talbot, 56 Or App 235, 641 P2d 617 (1982), which opinion this court adopted as its own, Multnomah County v. Talbot, 294 Or 478, 657 P2d 684 (1983). We decline to address those arguments, other than to note our agreement with intervenor that, according to this court’s case law describing those theories of standing, plaintiffs McCall, MacPherson, and Swaim have failed to establish it. See Hanson v. Mosser, 247 Or 1, 10-11, 427 P2d 97 (1967) (plaintiffs had standing as taxpayers, because they alleged that unlawful expenditures of public funds pursuant to questioned contract would increase their tax burden), overruled on other *660grounds by Smith v. Cooper, 256 Or 485, 488, 475 P2d 78 (1970); see also Webb v. Clatsop Co. School Dist. 3, 188 Or 324, 328-29, 215 P2d 368 (1950) (plaintiffs had standing as voters, because they alleged that polls had closed one hour earlier than had been publicized, preventing one plaintiff from voting, and because, at polling place, one plaintiff improperly had been disqualified from voting).
McCall plaintiffs initially submitted both affidavits to the trial court as evidence in support of their motion for a preliminary injunction. McCall plaintiffs specifically incorporated that evidence in their pleadings on their motion for summary judgment as evidence in support of that motion.
Intervenor also argues that all the local government plaintiffs lack standing because they are “mere instrumentalities of the state” and, therefore, may not “maintain an action against the state to strike down an initiative passed by the voters of the state.” He argues that a local government must have a “proprietary *663interest” at stake before it may request relief under the UDJA. In support of that contention, intervenor relies upon Tillamook Co., 302 Or 404. In Tillamook Co., however, this court specifically rejected the argument that intervenor makes here, that is, that “local governments” do not have standing to bring such challenges because they are “ ‘mere instrumentalities of the state.’ ” Id. at 415. This court instead focused upon whether the county in that case had any “protected, recognizable” interest that could be asserted against the state. Id. at 416. We have engaged in a similar inquiry here and have concluded that the local government plaintiffs have such an interest, which is sufficient to establish standing under ORS 28.020.
In light of our conclusion that only plaintiffs Lewis and Tipperman, among McCall plaintiffs, and the local government plaintiffs, among League plaintiffs, sufficiently alleged standing under ORS 28.020, we use the term “plaintiffs” to refer to only those plaintiffs for the remainder of this opinion.
Plaintiffs further contend that Measure 7 changes Article VI, section 10, Article XI, section 2, and Article IV, section 1(5) (all regarding home-rule authority *665and related initiative and referendum powers); Article XI, sections 7 and 10 (state and county debt limitations); Article XI, section 15(1) (unfunded mandates); Article IV, section 1(1) (legislative authority); Article VII (Amended), section 1 (judicial power); Article III, section 1 (separation of powers); and Article I, section 39, and Article XI, section 2 (local option). In light of our analysis respecting Article I, section 8, set out below, we need not address plaintiffs’ contentions that Measure 7 also changes several other provisions of the Oregon Constitution. See Swett, 333 Or at 607 (following same approach).
We note that the trial court based its conclusion that Measure 7 violated the separate-vote requirement primarily upon its determination that Measure 7 made various changes to Article I, section 18. However, that court relied upon the Court of Appeals’ “necessar[y] implication]” construct, set out in Dale v. Keisling, 167 Or App 394, 401, 999 P2d 1229 (2000), for determining whether a measure encompasses two or more amendments. This court later rejected that construct in Lehman, 333 Or at 241-42. The trial court also relied upon an alternative “policy choice” construct advocated by the state, which this court also rejected in Lehman, id. at 242.
This court noted in Miller that such an enactment might be permissible under Article I, section 8, if, in the context of vendors of merchandise, it were accompanied by an explanation as to how the sale of the nonexpressive material in question “meets a special need or how the sale of the expressive material in question gives rise to special problems reasonably justifying the regulation of the vendor of expressive material differently and more stringently than other vendors.” 318 Or at 491. No such “justification” or “special problems” appear here.
We note that, in both Miller and Tidyman, this court explained that such disparate treatment of persons engaged in expression implicates Article I, section 8, rather than Article I, section 20:
“ “We note at the outset that the obstacle to the city’s distinction [between ‘adult’ businesses and other businesses] is not the constitutional guarantee of equal privileges and immunities, Article I, section 20, but the guarantee of free expression, Article I, section 8. If free expression within that guarantee were not involved, ‘adult’ businesses could not insist that they must be treated exactly like any other business, not, at least, without a showing of being singled out for an impermissible motive.’ ”
Miller, 318 Or at 487 (quoting Tidyman, 306 Or at 182) (brackets added in Miller; Tidyman footnotes omitted in Miller).
