OPINION
¶ 1 This сase requires us to decide whether the gubernatorial veto of a portion of a bill related to state employee compensation exceeded the Governor’s item veto power under Article 5, Section 7 of the Arizona Constitution. We conclude that the vetoed provision is not an item of appropriation subject to the gubernatorial item vetо.
I.
¶ 2 On January 25 and 26, 2006, the Forty-seventh Legislature (the Legislature) passed House Bill 2661 (HB 2661) as an emergency measure. 1 Section 1 of HB 2661 expressed the Legislature’s intent to grant state employees a pay raise, and Section 6 appropriated money for employee salary adjustments. HB 2661, 47th Leg., 2d Reg. Sess. (Ariz. 2006). Section 5 of HB 2661 (Section 5) amended Arizona Revised Statutes (A.R.S.) section 41-771 (2004) and exempted certain employees hired after December 31, 2006, from the state merit system. Id.
¶ 3 On January 30, 2006, the Governor vetoed a portion of Section 5. 2 The Governor’s veto message stated that the item “would have created an additional expense to the state” because exempt employees accrue leave differently than do merit system employees.
¶ 4 On February 2, 2006, by separate votes, each chamber of the Legislature authorized its presiding officer to bring an action on behalf of the Legislature to challenge the constitutional validity of the Governor’s item veto of Section 5. Senate President Ken Bennett and Speaker of the House James Weiers then brought this special action, acting both individually and on behalf оf the Legislature.
II.
¶ 5 In deciding whether to accept jurisdiction of this special action, we consider several questions. Because resolution of some of these questions turns on whether this action involves legal or political issues, we define first the nature of the issues raised.
¶ 6 The Legislature asks us to determine whether Section 5 constitutes an “item of appropriation оf money” within the meaning of Article 5, Section 7 of the Arizona Constitution. The Legislature argues that if the provision is not an item of appropriation, then the Governor’s item veto power under the Arizona Constitution does not extend to Section 5. These issues, asserts the Legislature, are purely legal issues and appropriate for this Court’s consideration. The Gover *485 nor, in contrаst, argues that we can resolve the issues presented only by entering the political arena and that the Legislature has attempted to transform a political dispute into a constitutional question.
¶ 7 “Political questions,” broadly defined, involve decisions that the constitution commits to one of the political branches of government and raise issues not susceptible to judiсial resolution according to discoverable and manageable standards.
See Baker v. Carr,
¶ 8 We agree with the Legislature that this petition presents purely legal questions. To determine whether a branch of state government has exceeded the powers granted by the Arizona Constitution requires that we construe the language of the constitution and declare what the constitution requires. Such questions traditionally fall to the courts to resolve.
See Marbury v. Madison,
¶ 9 Our conclusion that determining the validity of an item veto presents a justiciable legal issue breaks no new legal ground. We have, on many occasions, considered whether particular gubernatorial actions exceeded a governor’s constitutional authоrity.
See, e.g., Bios v. Symington,
A.
¶ 10 This Court has original jurisdiction to issue extraordinary writs against state officers. Ariz. Const, art. 6, § 5;
Bios,
¶ 11 Whether to accept jurisdiction, however, remains a highly discretionary decision. State Bar Committee Note, Ariz. R.P. Spec. Act. 3;
see also McKaney v. Foreman ex rel. County of Maricopa,
209 Arz. 268, 275 ¶ 35,
B.
¶ 12 The fact that this aсtion raises issues appropriate for our consideration does not end our inquiry. We next consider whether the Legislature has standing to bring this action. Although “we are not constitutionally constrained to decline jurisdiction based on lack of standing,”
Sears v. Hull,
¶ 13 The Governor argues that these petitioners, like those in
Bennett,
lack standing. In
Bennett,
four state legislators, including the President of the Senate and the Speaker of the House of Representatives, brought a special action to challenge the governor’s veto of specific items in a general appropriations bill. Id. at 522 ¶ 3,
¶ 14 The situation here differs in several significant respects from that in
Bennett.
First, in contrast to
Bennett,
here the Legislature has alleged a particularized injury to the legislative body as a whole. The United States Supreme Court considered a similar situation in
Coleman v. Miller,
¶ 15 A majority of the members of the legislature can pass legislation, Ariz. Const, art. 4, pt. 2, § 15, subject to the governor’s veto power. If, as the Legislature asserts, the Governor’s item veto was unconstitutional and thus invalid, the Legislature’s right to hаve the votes of a majority given effect has been overridden and the Legislature, as an institution, has sustained a direct injury to its authority to make and amend laws by a majority vote.
¶ 16 Second, we held in
Bennett
that four of ninety legislators could not bring an action that allegedly belonged to the legislature as a whole “without the benefit of legislative authorization....”
¶ 17 Contrary to the Governor’s arguments, the Legislature’s failure to attempt to override the item veto does not preclude a finding that it has standing to bring suit. In
Bennett,
we considered thе legislature’s failure to attempt an override as a prudential concern that indicated we should not waive the lack of standing present there. Id. at ¶ 34,
¶ 18 Based on these circumstances, we conclude that the Lеgislature has alleged a direct institutional injury and has standing to challenge the validity of the Governor’s item veto of Section 5 of HB 2661. 6
III.
¶ 19 Article 5, Section 7 of the Arizona Constitution defines the governor’s item veto power. Under the terms of the constitution, the governor may veto “items of appropriations of money ... while approving other portions of [a] bill.” Ariz. Const, art. 5, § 7. An appropriation is “the setting aside from the public revenue of a certain sum of money for a specified object, in such manner that the executive officers of the government are authorized to use that money, and no more, for that object, and no other.”
Rios,
¶ 20 The setting aside of a certain sum of public revenue can occur in two ways: The legislature can authorize spending from the general fund or it can authorize payments of ascertainable amounts from a special fund.

See Crane v. Frohmiller,
¶ 21 Section 5 amends A.R.S. § 41-771, the statute that identifies those groups of employees who are exempt from the state merit system. It adds “correctional officers and juvenile correctional officers, state officers and employees who are appointed or employed after December 31, 2006 and who are at a pay grade of twenty-four or above” to the class of exempt employees.
¶ 22 On its face, Section 5 fails to set aside any sum from the general fund. That fact, however, does not preclude finding that the statute constitutes an item of appropriation if it sets aside revenue from some other specific limited source. In
Rios,
for example, we held that A.R.S. § 41-511.26 was an appropriation because when viewed in conjunction with the federal statute, the vetoed section “authorize[d] the creation of a fund” and granted authority to spend the monies in that fund.
¶ 23 Unlike the provisions considered in Rios, Section 5 fails to specify any fund from which payment for accrued leave or, more generally, payment to exempt employees may be made. Instead, it merely defines a class of employees that will be excluded from the state merit system.
¶ 24 The Governor argues that this failure to set aside funds does not disqualify Section 5 from being an appropriation because the “combined effect of the vetoed language and the employment practices statutes [in Title 23] ... turns the vetoed language into a spending authorization.” She asserts that, under current administrative regulations, exempt employees accrue more leave than do merit system emрloyees and, because the state must pay separating employees for accrued leave, Section 5 will impose additional costs to the state unrelated to employee salaries.
¶ 25 As the Governor correctly points out, A.R.S. § 23-353.B (1995) requires that an employee be paid “in the usual manner all wages due [to] him” upon leaving the service of an employеr, and A.R.S. § 23-350.5 (1995) defines wages as including vacation pay. The statutes, therefore, do obligate the state to make certain payments to separating employees. The Governor’s argument, however, incorrectly equates the
obligation
imposed by the statutes with an
appropriation
to fulfill the obligation.
See Crane,
*489 ¶26 In this case, Section 5, even when considered in conjunction with other statutes, does not set aside a defined amount of public revenue from any specific funding source. We conclude, therefore, that Section 5 was not subject to the Governor’s item veto power.
IV.
¶ 27 Because Section 5 of HB 2661 is not an appropriation, thе Governor’s item veto of that provision exceeded her constitutional authority and is invalid. Accordingly, we order that Section 5 be given full force and effect.
Notes
. The Arizona Constitution requires a two-thirds vote in each legislative chamber to pass a bill as an emergency measure. Ariz. Const, art. 4, pt. 1, § 1(3).
. The Governor item vetoed the portion of Seсtion 5 that adopted a substantive change to A.R.S. § 41-771 by adding a new class of employees to those exempt from the state merit system. The Governor left intact the remaining minor legislative changes made by Section 5.
. See cases cited supra ¶ 9.
. Although federal jurisprudence on issues of standing does not bind this Court, we regard federal decisions as instructive.
Bennett v. Napolitano,
. The Senate President and House Speaker also seеk standing as individuals. We previously rejected the argument that the President and the Speaker have standing to bring suit as individuals on behalf of the entire legislative body.
See Bennett,
. Because we find that the Legislature as a whole has established standing to bring suit, we need not address the prudential concerns outlined in
Bennett,
. Neither side suggests that the
Rios
discussion of reductions to or transfers from previously made appropriations,
see Rios v. Symington,
. Even the alleged fiscal impact of Section 5 results not from the statute but rather from state administrative rules and regulations and from employee manuals adopted by the executive branch. See Ariz. Admin. Code (A.A.C.) R2-5-403.B (non-exempt employees accrue annual leave from 3.7 hours to 6.47 hours bi-weekly, based on the number of years of service); A.A.C. R2-5-403.D (non-exempt employees may accrue up to 240 hours of compensatory leave each calendar year); Arizona Department of Administration, Human Resources Policies and Procedures (ADOA Manual), art. 4, § B (2004), available at htt p://www.hr,state.az.us/Homepagelinksf policies/content.htm (exempt employees accrue annual leave at a rate of 6.47 hours bi-weekly аnd have a maximum accrual of 320 hours of annual leave per calendar year). Because the *489 amount of annual leave to which employees, both exempt and non-exempt, are entitled is defined in administrative rules and procedures rather than by statute, see A.A.C. R2-5-403; ADOA Manual, art. 4, § B, the fiscal impact of Section 5 derives from matters committed to the executive branch, see A.R.S. § 41-703 (2004) (indicating that the governor oversees the direction, control, and operation of the Department of Administration).
