¶23 (dissenting) — The majority says that mandatory inclusion of one item in a proposed budget requires the governor to exercise discretion in reducing or eliminating other requests, and therefore mandamus is improper. There is, of course, a fixed amount of funding available to achieve a balanced budget, and one budget request included in a proposed budget means that there is less money remaining for other proposed requests. But this fact does not turn a mandatory duty into a discretionary one. Pursuant to a state law duly enacted by the legislature, the governor had a mandatory duty to include in the proposed 2009-2010 budget a request to fund the arbitration award in this case.
¶24 In this state, the legislature and the governor each have powers and responsibilities with respect to the budget and neither alone has unlimited discretion as to what must be, as opposed to may be, included. The flaw in the majority’s analysis is that it fails to recognize that while the governor has broad discretion with respect to proposed budget matters, the governor does not have discretion with respect to constitutionally or statutorily mandated items that must be included in the proposed budget.
*606¶25 This does not mean, contrary to the impression that the majority leaves, that the request to fund an arbitrator’s award must or will in fact be funded. There is no statutory requirement that the legislature has to approve the request. Rather, the statute assures that the question of funding receives due consideration by the legislature when it enacts a budget. When times are as economically difficult as they are now, the mandate that this request be made is unlikely to mean that the legislature will include such funding in the budget bill it enacts, and if the legislature did act to fund the request, the governor still retains the veto power.
¶26 The majority’s discussion of the present economy is therefore inappropriate. It is inappropriate for another reason as well. The majority actually says that even if mandamus were a suitable remedy, it would refuse to grant the writ because of the economic straits facing the State! This is a declaration of power that this branch of government does not have. We are not the legislature, and the court has no business upsetting the balance of powers between the executive and the legislative branches, no matter whether the members of this court think a particular budget item is wise or foolish. The other branches of government must carry out their constitutional and statutory duties without interference by this court. The legislature enacted a statute requiring, under the circumstances in this case, that the governor include a budget request to fund the arbitrator’s award. It is not for this court to rewrite the statute because it does not think such a request should be made during difficult economic times.
¶27 In short, this case is not about forcing a misappropriation of state funds in hard times, and it certainly is not about the degree of discretion that the governor has with respect to budget matters that are not mandated by statute or the constitution. It is about following the law — a duly enacted state statute — that required that the request be included in the governor’s proposed budget.
*607¶28 It is important to bear in mind that there are numerous other statutes mandating other specific duties that the governor must carry out with respect to a proposed budget. Absent a showing that a statute is unconstitutional (a showing that has not been made here), our obligation is to see that the laws are enforced as they are written. Unfortunately, the majority’s approach is to permit complete disregard for the law. Regardless of this particular dispute and current economic times, the majority opinion means no less than that any governor may flout any law regarding any mandatory budget requirement and absolutely nothing can be done about it.
¶29 Because this is a matter of great importance that is subject to recurrence whenever the law requires that a request be included in the governor’s proposed budget, this case should be decided regardless of mootness.
¶30 Finally, an important fact mentioned nowhere in the majority is that the governor was a party to the collective bargaining agreement at the heart of this case, with the Washington State Labor Relations Office (LRO) acting on her behalf. It was her contract, and she should not have been allowed to repudiate it in contravention of state law.
Facts
¶31 Assuming the issues in this case should be decided on the merits,14 my description of the facts is necessarily more complete than that presented in the majority.
¶32 Petitioner SEIU Healthcare 775NW (SEIU 775NW or the union) is the exclusive bargaining representative for approximately 25,000 individual providers who independently contract with the Washington State Department of Social and Health Services to provide in-home personal care to Medicaid-eligible clients. Agreed Statement of Facts (ASF775) *608¶ l.15 This long-term care services option allows elderly and disabled persons to receive personal care assistance in a residential setting, as an alternative to institutional care. SEIU 775NW sought a writ of mandamus directing Governor Christine Gregoire to submit a revised 2009-2010 budget to the legislature that included requests for funding to implement the compensation and benefit provisions of its collective bargaining agreement (CBA), determined through mandatory interest arbitration.
¶33 By statute, the governor is designated the public employer of the individual providers and the governor or the governor’s designee is charged with engaging in collective bargaining with the individual providers’ union. RCW 74.39A.270(1). Under the statutory scheme, the parties are subject to collective bargaining provisions in chapter 41.56 RCW, including the mandatory interest arbitration provisions of this chapter (with certain exceptions). RCW 74.39A.270(2)(c). By law, if the parties reach impasse on a subject of negotiation, that issue will go to mandatory interest arbitration and a decision of the arbitration panel is final and binding on the parties. Id.; RCW 41.56.440, .450, .480. An important component of the interest arbitration statutes is that the arbitrator must consider the parties’ evidence on the State’s ability to pay, RCW 41.56.465(5)(a)(ii), and make an award corresponding to that ability.
¶34 The LRO, a division of the Office of Financial Management (OFM), represented the governor in collective bargaining with the union. OFM is a division of the governor’s office. RCW 43.41.050. LRO and SEIU 775NW negotiated the compensation and fringe benefits terms at issue to impasse — thus triggering the requirement that an arbitrator would have to decide what these terms would be. After the parties reached impasse, an interest arbitration hearing was held, and LRO submitted extensive evidence *609about the economic circumstances and revenue downturn affecting the State’s ability to pay.
¶35 During the hearing, the arbitrator, Timothy Williams, heard from 28 witnesses and admitted 142 exhibits into evidence. Pursuant to RCW 41.56.465(5)(a)(ii), an arbitrator deciding issues for employees under RCW 74-.39A.270 must consider “[t]he financial ability of the state to pay for the compensation and fringe benefit provisions of a collective bargaining agreement.” LRO introduced testimony and exhibits relating to the financial condition of the State and the potential impact of any interest arbitration award on the state budget. ASF775 ¶ 7. OFM Deputy Director Wolfgang Opitz testified that based on the most recent Economic and Revenue Forecast Council report and projections prepared by the Senate Ways and Means Committee staff, there would be a $2.7 billion shortfall for the 2009-2011 biennium, which would be reduced to $1,956 billion if the State’s “rainy day” fund was spent. ASF775 Ex. 4, at 615 (JSF775 004516), Ex. 8, at JSF775 0280.
¶36 The arbitrator considered the substantial evidence that the governor’s representative submitted on the issue of the State’s ability to pay and factored it into his award, which was issued on October 1, 2008. The arbitrator emphasized that “clearly, the most significant problem faced by both the State and the Union with regard to completing the 09-11 collective bargaining agreement is the concern with the State’s ability to pay for any increased costs.” ASF775 Ex. 10, at JSF775 0304. He noted the award was “being written at a time when the front page of every newspaper carries the message that we are in the midst of one of the darkest times in the history of American financial markets” and that “[t]his cannot bode well for the financial well being of the State of Washington.” Id. He then said, “To put it bluntly, the award is not a rich one.” Id. He said that *610“he found merit in many of the Union’s proposals but ultimately... determined not to award the provisions solely on the basis of cost.” Id. He called the “projected budget shortfall” “the dominant factor” in the award related to wages. Id. at JSF775 0320. The arbitrator awarded an approximately 2.4 percent increase to take effect in July 2009 and a 2.0 percent increase in July 2010. Id. at JSF775 0318-19. The union membership voted to ratify the contract. ASF775 ¶ 11.
¶37 RCW 74.39A.300 is the state statute that requires that the governor include the arbitration award in the proposed budget to the legislature. RCW 74.39A.300(1) states that the governor must submit a budget request for funds to implement compensation and fringe benefits provisions of a CBA entered into under RCW 74.39A.270 (or she must propose legislation necessary to implement such an agreement). RCW 74.39A.300(2) provides that (a) a request for such funds must have been submitted to the director of OFM by October 1 of the year prior to the legislative session when the request will be considered and (b) the request must have “been certified by the director of financial management as being feasible financially for the state or reflects the binding decision of an arbitration panel.” (Emphasis added.) LRO timely submitted a copy of the arbitration decision and a summary of the costs of the arbitration award, plus costs associated with monetary issues that were successfully negotiated without interest arbitration, to the OFM director. ASF775 ¶ 9.
¶38 In November 2008, the Economic and Revenue Forecast Council issued a quarterly report that stated that economic conditions had “deteriorated sharply” and reported “[v]ery weak revenue collections” with an expectation of “a sharp decline in consumer spending ... so the impact on state revenues will be more severe” than during the downturn in 2001. ASF775 Ex. 12, at JSF775 0406. The revenue forecast was $1.4 billion lower than it had been two months earlier, and $1.65 billion lower than predicted in June. On December 4, 2008, the Senate Ways and Means *611Committee produced a report predicting that including the shortfall for the current biennium, the total budget problem could reach $6 billion, not including the State’s “rainy day” fund of $700 million. ASF775 Ex. 13, at JSF775 0521.
¶39 On December 17, 2008, the director of OFM advised Governor Gregoire that the collective bargaining agreements and arbitration awards that had been submitted to him — a total of 33 agreements that included the SEIU 775NW agreement — were not feasible financially for the State and therefore could not be included in the proposed budget. ASF775 Ex. 14, at JSF775 0532.17
¶40 Also, on December 18, 2008, the governor submitted her proposed biennial budget to the legislature.18 By law, the governor must propose a balanced budget. The budget the governor submitted did not include a request for funding to implement compensation and fringe benefit increases decided through arbitration or funding to implement compensation or money contributions to which the parties agreed. ASF775 ¶ 16.19
¶41 On December 29, 2008, SEIU 775NW filed an original action in this court seeking a peremptory writ of mandamus compelling the governor to withdraw the budget she had submitted to the legislature and submit a revised balanced budget to the legislature that included funding and legislative authorization for its CBA. It is, of course, too late for this court to provide the relief requested, but the issue here, and more specifically the issue of the extent of the governor’s discretion with respect to items that are statutorily required to be included in the proposed budget, is of such importance that the court should decide all of the issues presented in this case.
*612Analysis
I
¶42 SEIU 775NW contends the governor failed to carry out a mandatory statutory duty to include in her proposed budget submitted to the legislature a request for funding the arbitrated compensation and fringe benefits provisions in the individual providers’ CBA. The State contends that a writ of mandamus is improper because the governor has discretion as to what is included in the budget document, limited only by the state constitution. Unfortunately, the majority agrees with the State. However, both the executive and the legislative branches of government are involved in development and adoption of the state budget. The governor does not have unlimited discretion as to what the budget will contain.
¶43 The State relies on article III, section 6 of the Washington State Constitution, which provides that the governor “shall communicate at every session by message to the legislature the condition of the affairs of the state, and recommend such measures as he shall deem expedient for their action,” and on the budget and accounting act of 1959 (Laws of 1959, ch. 328), chapter 43.88 RCW, in particular RCW 43.88.030. The State also urges that the word “must” in RCW 74.39A.300(1) has to be construed to be permissive in order to preserve this discretion and to avoid constitutional infirmity. See Residents Opposed to Kittitas Turbines v. State Energy Facility Site Evaluation Council, 165 Wn.2d 275, 299, 197 P.3d 1153 (2008).
¶44 Contrary to the State’s argument, article III, section 6 is not infringed by construing the word “must” in RCW 74.39A.300(1) as mandatory. Under our state government, the legislative branch enacts the laws and also determines the State’s final budget and for what purposes appropriations will be made, subject to the governor’s veto. See Const. art. II, § 1, art. VIII, § 4, art. III, § 12; Dicomes v. State, 113 *613Wn.2d 612, 622, 782 P.2d 1002 (1989) (under the budget and accounting act “funds are ‘appropriated’ upon adoption of a budget by the Legislature[,] RCW 43.88.080”). In enacting the statutory scheme at issue, the legislature obviously wanted the question of funding individual providers’ CBAs brought to its attention in the budget document, once it had been determined that the State could pay. To this end, it mandated that the governor include a funding request in her budget. The legislature also had in mind the importance of a determination that the State has the ability to pay for compensation and fringe benefits provisions in the CBAs. The legislature ensured that the executive branch’s evidence of financial feasibility will be considered, either at the time of interest arbitration or by the director of OFM if the parties successfully negotiate the compensation and fringe benefit provisions. Financial feasibility continues to be a consideration as the legislature determines what the final state budget will be and whether it will make appropriations for the compensation and fringe benefit provisions in the individual providers’ CBA, and as the governor decides whether to exercise the veto power.
¶45 As I emphasized at the outset of this opinion, inclusion of the request in the proposed budget does not mean that the request for these funds will be approved; indeed, in the economic environment prevailing when the legislature considered the 2009-2011 budget, it was unlikely to have been approved.
¶46 Our state constitution does not contain a separation of powers clause, but the division of our state government into different branches has been presumed throughout this state’s history to give rise to a separation of powers doctrine. Brown v. Owen, 165 Wn.2d 706, 718, 206 P.3d 310 (2009). The separation of powers doctrine primarily serves to ensure that the fundamental functions of each of the branches of government remain inviolate. Id. Each branch is allowed to exercise limited control over the others in the form of checks and balances. Id. at 720. As we have often explained, the overlapping of functions among the three *614branches of government “allows for the scheme of checks and balances which . . . evolved side-by-side with and in response to the separation of powers concept. Legislative control over appropriations, the executive power to veto, and the judicial authority to declare legislative and executive acts unconstitutional are all examples of direct control by one branch over another.” In re Salary of Juvenile Dir., 87 Wn.2d 232, 242-43, 552 P.2d 163 (1976) (emphasis added) (citations omitted). The separate branches of government are not hermetically sealed and some overlap must exist; one branch of government may be involved in functions of another branch or in functions that overlap functions of another branch without violation of the separation of powers doctrine so long as the first branch does not undermine the operation of the other branch or the rule of law that all branches must maintain. Carrick v. Locke, 125 Wn.2d 129, 135, 882 P.2d 173 (1994); see Juvenile Dir., 87 Wn.2d at 241-43.
f 47 In the context here, the executive branch negotiates the CBAs and, with respect to negotiated terms, makes a direct determination of financial feasibility. With respect to arbitrated terms, the executive branch produces evidence as to whether the State is in a position to fund them. Once a determination of feasibility is made according to the requirements of the statute, then, pursuant to the legislature’s statutory mandate, a budget request for funding must be made. This mandate does not result in an unconstitutional encroachment on gubernatorial powers.
¶48 As the Montana State Supreme court explained, in a similar case, there are areas in which “common links” of connection or dependence occur between branches of state government, and budgeting is one such common link. Huber v. Groff, 171 Mont. 442, 455, 558 P.2d 1124 (1976). The court explained that under Montana’s scheme, “[t]he executive depends on the legislature for funding and because the legislature must set the state’s budget in a ninety day session every other year, and because this is a period when there are numerous other matters to attend to, the legisla*615ture must also rely on the executive to provide the information it needs to budget intelligently.” Id. Under the Montana Constitution and statutes, the governor has to submit a budget in a certain form with specified contents and is prohibited from altering any legislative appropriation request. Id. The court concluded that there was no constitutionally prohibited invasion on the executive’s power when the legislature required by statute that the governor include certain fund requests in the budget.
¶49 As in Montana, in Washington the executive branch depends upon the legislative branch for funding. Like Montana’s, our state legislature has 90 days to adopt the final budget and attend to other matters, and relies on the governor to provide information to budget intelligently and also to assist it in achieving a budget in accord with its own legislation involving funding matters. Also, as explained next, the governor must include “statutory expenditures” in her budget and must submit her budget in a certain form with specified content. Like the court concluded in Huber, there is no invasion into the executive’s powers as a result of the requirement that the governor include the budget request mandated by the plain language of RCW 74.39A.300(1).
¶50 Turning to the budget and accounting act, upon which the State also relies, it is true that the act lodges a great deal of discretion in the governor. SEIU 775NW does not dispute this. However, the act requires that the budget document be submitted to the legislature in a particular form and specifies matters that must be included in the budget document. RCW 43.88.030. It specifically constrains the governor’s exercise of discretion and, contrary to the State’s claim, these constraints are not all constitutionally based. For example, the governor must include in the budget document “[p]ayments of all reliefs, judgments, and claims.” RCW 43.88.030(2)(b). The act also provides that other “statutory expenditures” must be included. Id. at (2)(c). This subsection expressly contemplates that expenditures mandated by the legislature must be included. Both *616of these provisions have been in the act since it was enacted and, significantly, the State does not contend that any portion of the budget and accounting act is unlawful.20
¶51 Contrary to the State’s argument, it is not necessary to interpret “must” in RCW 74.39A.300(1) as permissive to avoid encroachment on the governor’s discretion. In the area of the budget, the governor and the legislature both have power, and the governor’s discretion must be considered in light of powers granted to the legislative branch, which has the power and the duty to make appropriations necessary to implement state policy and programs, among other things.
¶52 Ultimately, whether any appropriation is made is up to the legislature, subject to gubernatorial veto. If economic conditions change between the time an interest arbitrator determines the State can pay an arbitration award and the time when a proposed budget is submitted to the legislature, or even later, the legislature can consider the changed conditions when it decides what will be included in the final budget and what appropriations will be made, and the governor can consider it when deciding whether to exercise the veto power.
II
¶53 As is apparent, the parties disagree about the interpretation to be given the relevant statutes, in particular, RCW 74.39A.300, and about whether a writ of mandamus should issue.
*617¶54 Mandamus is an extraordinary writ. Walker v. Munro, 124 Wn.2d 402, 407, 879 P.2d 920 (1994). This court has original, nonexclusive, discretionary jurisdiction in mandamus as to all state officers. Const. art. IV, § 4; RAP 16.2(a); Staples v. Benton County, 151 Wn.2d 460, 464, 89 P.3d 706 (2004); Walker, 124 Wn.2d at 407. Mandamus is an appropriate remedy to compel performance of a specific, existing duty that a state officer has violated and continues to violate. Walker, 124 Wn.2d at 408. “A mandatory duty exists when a ... statute directs a state officer to take some course of action.” Brown, 165 Wn.2d at 724. Mandamus may not be used to compel performance of duties that involve a public official’s discretion. Walker, 124 Wn.2d at 410; RCW 7.16.160 (the writ is appropriate only where a state officer fails to perform “an act which the law especially enjoins as a duty resulting from an office”).
¶55 The governor has a specific mandatory duty to include requests in the budget to the legislature for funds necessary to implement the union’s CBA. RCW 74.39A.300 states in part:
(1) Upon meeting the requirements of subsection (2) of this section, the governor must submit, as part of the proposed biennial or supplemental operating budget submitted to the legislature under RCW 43.88.030, a request for funds necessary to administer chapter 3, Laws of 2002 and to implement the compensation and fringe benefits provisions of a collective bargaining agreement entered into under RCW 74.39A.270 or for legislation necessary to implement such agreement.
(2) A request for funds necessary to implement the compensation and fringe benefits provisions of a collective bargaining agreement entered into under RCW 74.39A.270 shall not be submitted by the governor to the legislature unless such request:
(a) Has been submitted to the director of financial management by October 1st prior to the legislative session at which the request is to be considered; and
(b) Has been certified by the director of financial management as being feasible financially for the state or reflects the *618binding decision of an arbitration panel reached under RCW 74.39A.270(2)(c).[21]
(Emphasis added.)
¶56 The two statutory prerequisites are met if the request for funds has been submitted to OFM and either the director of OFM certifies it as being financially feasible or the request reflects a binding arbitration decision. The “or” in the statute is disjunctive, requiring either the director’s determination of feasibility or a binding arbitration decision. See, e.g., Tesoro Ref. & Mktg. Co. v. Dep’t of Revenue, 164 Wn.2d 310, 319, 190 P.3d 28 (2008); State v. Tiffany, 44 Wash. 602, 603-04, 87 P. 932 (1906). A determination of financial feasibility by the director of OFM is not required when there is a binding arbitration decision. Under the governing statute, the State’s ability to pay is accounted for in an arbitration decision where the arbitrator must take into account evidence of the state’s financial ability to pay. RCW 41.56.465(5)(a)(ii).
¶57 Once the two prerequisites are satisfied, the word “must” in RCW 74.39A.300(1) (“the governor must submit”) is mandatory and the governor is required to include a request for funding in the budget document to the legislature. See Graham Thrift Grp., Inc. v. Pierce County, 75 Wn. App. 263, 267, 877 P.2d 228 (1994). The State’s contention that an arbitration decision is not binding until the legislature approves the funding is based on the fact that the arbitration provisions of RCW 41.56.430 through .470 and RCW 41.56.480 apply except that “[t]he decision of the arbitration panel is not binding on the legislature and, if the legislature does not approve the request for funds necessary to implement the compensation and fringe benefit provisions of the arbitrated collective bargaining agreement, is not binding on the authority or the state.” RCW *61974.39A.270(2)(c)(ii).22 The State urges that under these statutes an arbitration decision is not binding on the State unless the legislature has approved funding, and because this has not occurred, the arbitrator’s decision is not a “binding decision of an arbitration panel” for which the governor must request funding in the budget.
¶58 When the language of a statute is plain and unambiguous, the court is to give effect to that plain language as the expression of the legislature’s intent. Tingey v. Haisch, 159 Wn.2d 652, 657, 152 P.3d 1020 (2007). The plain meaning of a statutory provision is determined from the ordinary meaning of the language at issue, the statutory context, related statutory provisions, and the statutory scheme as a whole. Id. The court considers the general object to be considered and the consequences that would ensue if a statute is read in a particular way. State v. Krall, 125 Wn.2d 146, 148, 881 P.2d 1040 (1994).
¶59 RCW 74.39A.270(2)(c)(ii) says that the arbitrator’s decision is not binding on the legislature, the authority, or the State until approved by the legislature. But the mediation and arbitration provisions of RCW 41.56.430 through .470 and RCW 41.56.480 expressly apply to collective bargaining between SEIU 775NW and LRO, the subdivision of OFM that represents the governor. One of these statutes, RCW 41.56.480, provides that “[a] decision of the arbitration panel shall be final and binding on the parties, and may be enforced at the instance of either party.” (Emphasis added.) See also RCW 41.56.450 (written determination of the issues in dispute “shall be final and binding upon both parties”). By law the governor is the employer and a party to the agreements and by law the governor is bound by the agreements.
¶60 Moreover, because RCW 74.39A.270 and .300 provide that until a request for funding is made and approved by the legislature, the agreements are not binding on the *620State and additionally provide that the governor must request funding if the statutory prerequisites are met; read as a whole these statutes contemplate that a governor’s request for funding necessarily has to be made at a time when the arbitrators’ decisions are not binding on the legislature, authority, or the State.
¶61 In addition, the State’s interpretation leads to an absurd result because, read as the State urges, RCW 74.39A.300 means that the duty to submit a request to fund arbitrated contracts to the legislature does not arise until the legislature has already approved and funded those very contracts. But once the legislature has determined to fund an arbitrated contract, there would be no reason for the governor to include a request for such funding. Courts should avoid reading a statute in a way that results in unlikely, absurd, or strained consequences; it will not be presumed that the legislature intended absurd results. Tingey, 159 Wn.2d at 663-64.
¶62 The State says, however, that the statutes retain meaning under its interpretation because if the legislature approves funding, the agreement is binding and the governor could not eliminate or reduce those amounts in the budget document for a supplemental budget. But RCW 74.39A.300(1) directs that the governor must request necessary funds "as a part of the proposed biennial or supplemental operating budget.” (Emphasis added.) The statute expressly contemplates that the budget document for the biennium is to include such a request.
¶63 The State next points out that the mediation and arbitration provisions in RCW 41.56.430 through .470 and RCW 41.56.480 provide for binding arbitration for uniformed personnel — law enforcement personnel and fire fighters — in order to provide a binding method of resolving disputes while prohibiting these employees from striking. The State contends that as to this limited class of employees, an arbitrator’s decision is final and binding, but not as to employees subject to mediation and arbitration under RCW 74.39A.270(2)(c).
*621¶64 Again, the statutes’ language contradicts the State’s interpretation. RCW 74.39A.270(2)(c) expressly states that RCW 41.56.480 applies. It then lists two exceptions to application of the mediation and arbitration provisions. One is the exception relied on by the State that says the arbitrators’ decisions are not binding on the legislature (nor on the authority or the State) until approved by the legislature, which, as explained, does not apply here. The other exception relates to when collective bargaining must commence. Because RCW 74.39A.270(2)(c) expressly lists the exceptions that apply, it would be contrary to the legislature’s intent if this court were to read another exception into the statute. See Allan v. Univ. of Wash., 140 Wn.2d 323, 345-46, 997 P.2d 360 (2000).
¶65 The State offers a number of other arguments in support of its position that the governor has no mandatory duty to include requests for funding the petitioners’ contracts. The State emphasizes the fact that public collective bargaining does not mirror private sector collective bargaining because the public is an essential party in the former but not the latter. The State says that a statute cannot bind OFM or the governor, or their offices or agencies, to spend money or incur liability without an appropriation for that purpose, or to bind the legislature to make an appropriation. To do so, the State contends, would violate the prohibition in article VIII, section 4 of the Washington State Constitution that “[n]o moneys shall ever be paid out of the treasury of this state . . . except in pursuance of an appropriation by law.” Likewise, the State says, RCW 43.88.130 provides that it is unlawful for a state agency to expend or contract to expend or incur liability in excess of appropriated amounts.
¶66 But the ultimate decision as to funding of the contracts remains at all times with the legislature. Under RCW 74.39A.270(2)(c)(ii), the legislature must approve the request to fund the collective bargaining agreements before any expenditure of state funds can occur. There is no danger of violation of article VIII, section 4 or of RCW 43.88.130 relating to expenditure of state funds.
*622¶67 The State also argues that arbitration panels do not perform the same role as the director of OFM in certifying financial feasibility. The State says that the requirement that arbitrators consider the State’s financial ability to pay for compensation and benefit provisions of CBAs, RCW 41.56.465(5)(a)(ii), is not equivalent. The OFM director’s determination occurs later than the arbitrators’ decisions, which pertain to financial ability only as of the time of their decisions. The State reasons this case shows that financial conditions can change markedly by the time the director’s determination of feasibility is made. The State also says that unlike the arbitrator’s decision, the director’s and governor’s determinations are constrained by the requirement of a balanced budget. Finally, the State urges that interest arbitration panels are not sufficiently knowledgeable or competent to evaluate all the multitude of programs and initiatives of the State and the policy decisions that must be made when planning the budget.
¶68 It is true that an arbitrator’s decision occurs earlier in the process than a determination by the director of OFM as to financial feasibility, but the fact is that an economic downturn or upturn might occur at any time during the process. A delay of a few months of the current downturn would have meant that when the director made his determination the outlook might have led him to find financial feasibility, which could have changed by the time the budget was being considered by the legislature. More importantly, though, the statutory language is straightforward and permits satisfaction of the second prerequisite by either the director’s determination of financial feasibility or a binding arbitration agreement. Neither determination will bind the State to pay — that is in the hands of the legislature. As SEIU 775NW contends, it is within the legislature’s purview to account for what would have been an unforeseeable event at the time an arbitrator makes a decision on the State’s financial ability to pay.
¶69 The State also questions the wisdom of the statutory provisions pertaining to financial feasibility. The State *623contends that it makes no sense for negotiated agreements to be subject to the requirement that the director of OFM determine financial feasibility, while a request for funds must be made in the case of arbitrated agreements. The State contends it makes less sense that when the parties reach impasse on some issues the issues that go to interest arbitration are binding and must be submitted in the governor’s budget, while negotiated terms are subject to the OFM director’s determination of financial feasibility.
¶70 The statute plainly treats negotiated and arbitrated terms differently. But SEIU 775NW is correct that the legislature deliberately equated the roles of the OFM director and the arbitrator in assessing whether the State is in a position to fund the contract terms. The statute also plainly provides that if, as in the present case, some of the terms are negotiated and the director of OFM issues a determination they are not feasible financially, a request to fund them cannot be included in the governor’s budget. A request to fund the provisions that resulted from interest arbitration, however, must be included and the legislature must approve or deny this request as a whole. ROW 74.39A.300(7).23
¶71 Finally, as to the meaning of ROW 74.39A.300(1), the State contends that even if “must” is mandatory, it refers only to the process by which, i.e., how, the governor is to request funding, if she requests it. I cannot agree that this is the intended meaning of the statute. First, the placement of commas setting off the clause beginning “as a part of the proposed” budget contradicts the State’s reading. “A comma serves many functions, but its purpose always is to set a phrase apart from the rest of the sentence.” E. Gig Harbor Improvement Ass’n v. Pierce County, 106 Wn.2d 707, 713, 724 P.2d 1009 (1986). Thus, the section states that as a substantive matter the governor *624must submit a request for funds, and that the request must be included in the proposed budget, if the requirements of subsection (2) are met. Further, subsections (1) and (2) together show when a request must be made and when it cannot be made. The relationship between the two indicates they are of the same nature, and subsection (2) plainly directs that as a substantive matter, the governor cannot submit a request if the requirements set out are not met. By the same token, the first section pertains to when the governor has to submit a request, not how one is submitted. Finally, if all that RCW 74.39A.300(1) entailed were directions for how to submit a request, the provision would be superfluous. The statute expressly refers to RCW 43.88.030, which itself sets out the “process” for including requests in the governor’s proposed budget. A court should avoid interpretation of statutes that renders their language superfluous. See In re Det. of Martin, 163 Wn.2d 501, 510, 182 P.3d 951 (2008) (quoting Whatcom County v. City of Bellingham, 128 Wn.2d 537, 546, 909 P.2d 1303 (1996)).
¶72 Lastly, reading the statute merely to overcome concerns about “transparency” is unnecessary. Under RCW 74.39A.300(5) the governor “shall periodically consult with the joint committee on employment relations established by RCW 41.80.010 regarding appropriations necessary to implement the compensation and fringe benefit provisions of any collective bargaining agreement and, upon completion of negotiations, advise the committee on the elements of the agreement and on any legislation necessary to implement such agreement.” This communication serves to keep the legislature informed about the budget implications of the CBAs. It is also an example of the interplay between the branches of government with regard to the budget, discussed in part I above.
¶73 I would hold that by its plain language RCW 74.39A.300(1) sets forth a mandatory duty for the governor to request funds if the two requirements in subsection (2) are met. RCW 74.39A.300(2)(b) is satisfied if the request reflects the binding decision of an arbitration panel reached *625under RCW 74.39A.270. A “binding decision of an arbitration panel reached under RCW 74.39A.270(2)(c)” is a decision under the applicable collective bargaining provisions in chapter 41.56 RCW. RCW 74.39A.300(2)(b). In particular, it is the “final and binding decision” identified in RCW 41.56.480.
¶74 The State maintains, however, that even if the duty to request funds under RCW 74.39A.300(1) is mandatory and does not merely describe procedure, that duty does not involve the performance of a ministerial act subject to mandamus. As explained, the fact that a request for funds for one purpose may require adjustments elsewhere does not affect the determination that the duty specifically at issue, here, the governor’s duty to request certain funding for a specific limited purpose, is nondiscretionary and ministerial. Accordingly, the governor has a mandatory ministerial duty to request funds to implement the arbitrated terms of SEIU 775NW’s agreement.
¶75 A writ of mandamus will be issued only when there is no plain, speedy, and adequate remedy at law. RCW 7.16.170; Staples, 151 Wn.2d at 464.
A remedy is not inadequate merely because it is attended with delay, expense, annoyance, or even some hardship.
“There must be something in the nature of the action or proceeding that makes it apparent to this court that it will not be able to protect the rights of the litigants or afford them adequate redress, otherwise than through the exercise of this extraordinary jurisdiction.”
State ex rel. O’Brien v. Police Court, 14 Wn.2d 340, 347-48, 128 P.2d 332 (1942) (citations omitted) (quoting State ex rel. Miller v. Superior Court, 40 Wash. 555, 559, 82 P. 877 (1905)).
¶76 SEIU 775NW says that the State does not dispute that the union lacks any plain, speedy, or adequate remedy *626at law.24 The State does not include this remedy issue as one of its arguments in the briefing, although it does suggest in the course of other arguments that its interpretation of RCW 74.39A.300(1) does not prevent the petitioners from seeking, and the legislature from appropriating, the funds needed to implement their agreements. What SEIU 775NW sought, however, was the governor’s inclusion of funding requests in her official budget document. A request directly from the union would not involve the same formality or carry the same weight. Adequate redress was not available other than by way of the extraordinary writ.
Conclusion
¶77 The word “must” in RCW 74.39A.300(1) is mandatory and requires the governor to include requests in the budget document submitted to the legislature for funds to implement compensation and fringe benefit provisions in CBAs entered into pursuant to RCW 74.39A.270 when the prerequisites of RCW 74.39A.300(2)(a) and .300(2)(b) are satisfied. Subsection (b) is satisfied if the request reflects the binding decision of an arbitration panel reached under RCW 74.39A.270 (which directs that the mediation and interest arbitration provisions in RCW 41.56.430 through .470 and RCW 41.56.480 apply; RCW 41.56.480 contains the description of “binding decision” for purposes of RCW 74.39A.300(2)(b)).
¶78 This court should have granted the petition for a writ of mandamus requiring the governor to submit a revised budget document to the legislature that included a request for funds to implement the compensation and fringe benefit provisions of the CBA entered into under RCW 74.39A.270. Absent its having done so in time for its decision to be effective for the present dispute, it should nonetheless have reached this conclusion to provide guid*627anee in future disputes where there is a question concerning a mandatory duty to include an item as part of the proposed budget that the governor submits to the legislature. At a minimum, this court should not grant the governor unlimited discretion to submit a proposed budget without regard to mandatory duties and should not inject itself into policy questions that are the province of the executive and legislative branches of government.
¶79 I dissent.
Sanders, Owens, and Fairhurst, JJ., concur with Madsen, C.J.The majority says this case may be moot hut proceeds to the merits anyway. Since I disagree with the majority on the merits, I, too, answer the issues.

This conclusion represents the director’s understanding of the law and it is, as explained below, incorrect with regard to arbitrated provisions under the statutes that apply here.
Under ROW 43.88.060, the governor must submit the budget document no later than December 20 of the year preceding the year of the legislative session during which it will be considered.
The 2009 legislative session began January 12, 2009, and the last day of the regular session was April 26, 2009. ASF775 ¶ 18.
The State cites Dicomes, 113 Wn.2d at 622, for the proposition that it is within the discretion of the governor to determine the scope and extent of budget requests. This case did not concern a question about the power of the governor to formulate a budget for submission to the legislature. It involved a tort claim for wrongful discharge in violation of public policy where the plaintiff argued that she had been discharged for releasing information indicating that the Department of Licensing budget did not include expenditure of surplus funds that had accumulated in the medical disciplinary account. The court explained that the governor submits a budget to the legislature that consists of budget proposals compiled by individual agencies and that “it is generally within the discretion of the agency head and the Governor to determine the scope and extent of budgetary requests.” Id. The court did not say that the governor has unlimited discretion in formulating the budget document for submission to the legislature.
The parties agree that the arbitrator is the “arbitration panel.’
The “authority” referred to is the “home care quality authority.” RCW 74.39A.240(1).
This statute adds that if the legislature rejects or does not act on the submission, then the agreement must be reopened “solely for the purpose of renegotiating the funds necessary to implement the agreement.” RCW 74.39A.300(3).
SEIU 775NW also says, correctly, that the State does not dispute that it is beneficially interested and thus has standing to bring an action for mandamus. See RCW 7.16.170.
