YOUNG, C.J.
Plaintiffs are several unions that represent employees in the state classified civil service. Their members are the beneficiaries of and participants in Michigan’s retirement system established under the State Employees’ Retirement Act (SERA).1 SERA was enacted in 1943 and has been amended many times since. Plaintiffs challenge the most recent SERA [316]*316amendment, 2011 PA 264. They contend that, because 2011 PA 264 increases the cost and reduces the accumulation of future pension benefits previously recognized, it unconstitutionally infringes the exclusive constitutional powers of the Civil Service Commission (commission) to manage and oversee the civil service system. The commission has never formally opposed or attempted to repudiate the application of SERA or any of its several amendments, including 2011 PA 264, to the employees of the state classified civil service.
While the commission has considerable constitutional powers to manage the civil service system and to preserve its sphere of constitutional authority, the commission has no legislative powers. It may neither enact legislation nor revise an enactment, nor may it dictate that the Legislature repeal or modify an enactment. Therefore, we hold that because the commission has acquiesced in the application of SERA to the employees of the civil service system, plaintiffs objections fail to establish a basis for relief.
We reverse the judgment of the Court of Appeals and remand to the Court of Claims for further proceedings consistent with this opinion.
I. FACTS
A. BACKGROUND
In 1940, through an initiative petition, the people of Michigan ratified a constitutional amendment establishing a state civil service system.2 Const 1908, art 6, § 22 became effective on January 1,1941, and provided in part:
[317]*317The commission shall classify all positions in the state civil service according to their respective duties and responsibilities, fix rates of compensation for all classes of positions, approve or disapprove disbursements for all personal services, determine by competitive performance exclusively on the basis of merit, efficiency and fitness the qualifications of all candidates for positions in the state civil service, make rules and regulations covering all personnel transactions, and regulate all conditions of employment in the state civil service. No person shall be appointed to or promoted in the state civil service who has not been certified as so qualified for such appointment or promotion by the commission. No removals from or demotions in the state civil service shall be made for partisan, racial, or religious considerations.
The administration of the commission’s powers shall be vested in a state personnel director who shall be a member of the state civil service and who shall be responsible to and selected by the commission after open competitive examination.
Shortly after its creation, the commission promulgated a rule requiring its state personnel director to recommend that the Legislature establish a retirement plan for classified employees:
RETIREMENT. The director, in conjunction with appointing authorities, other supervising officials, the state budget director and members of the legislature, shall prepare and submit to the commission for approval and subsequent recommendation to the governor and the legislature for adoption by law, a comprehensive and workable contributory retirement system for employees in the state civil service.131
Apparently, the commission thereafter designed a model retirement plan, which it submitted to the Governor for comment. However, before the Governor [318]*318completed his review of the commission’s plan,4 the precursor to SERA was introduced in the House of Representatives as House Bill No. 177.5 SERA was signed into law as 1943 PA 240, and was codified as MCL 38.1 et seq.
Subsequently, the people ratified a new Constitution in 1963, which altered somewhat the way that the commission operates. Const 1963, art 11, § 5, ¶ 4, remains largely unchanged from Const 1908, art 6, § 22, and provides in relevant part:
The commission shall classify all positions in the classified service according to their respective duties and responsibilities, fix rates of compensation for all classes of positions, approve or disapprove disbursements for all personal services, determine by competitive examination and performance exclusively on the basis of merit, efficiency and fitness the qualifications of all candidates for positions in the classified service, make rules and regulations covering all personnel transactions, and regulate all conditions of employment in the classified service.[6]
In the same section, however, the ratifiers introduced a new legislative check on compensation increases for civil servants authorized by the commission:
Increases in rates of compensation authorized by the commission maybe effective only at the start of a fiscal year [319]*319and shall require prior notice to the governor, who shall transmit such increases to the legislature as part of his budget. The legislature may, by a majority vote of the members elected to and serving in each house, waive the notice and permit increases in rates of compensation to be effective at a time other than the start of a fiscal year. Within 60 calendar days following such transmission, the legislature may, by a two-thirds vote of the members elected to and serving in each house, reject or reduce increases in rates of compensation authorized by the commission. Any reduction ordered by the legislature shall apply uniformly to all classes of employees affected by the increases and shall not adjust pay differentials already established by the civil service commission. The legislature may not reduce rates of compensation below those in effect at the time of the transmission of increases authorized by the commission.171
Following the ratification of the 1963 Constitution, the commission replaced its initial retirement rule, Rule XXXVIII, but its replacement did not purport to fundamentally change the commission’s advisory role in SERA’s administration:
Section 31 — Retirement.
31.1 Cooperation With State Retirement Board. —
The state personnel director shall cooperate with the State Employees’ Retirement Board in maintaining a comprehensive contributory retirement system for state civil service employees.181
The commission’s rules have remained substantively unchanged in this regard.9
[320]*320B. 2011 PA 264
In 2011, the Legislature amended SERA.10 Relevant to the instant case are the amendments of MCL 38. le, MCL 38.35a, and MCL 38.50a. Broadly speaking, the amendments (1) potentially reduce the value of overtime compensation as it factors into a member’s pension formula for future benefits,11 and (2) require members to make an election between paying to remain in a defined benefit plan (that was previously free), or instead joining a “Tier 2,” 401(k)-style defined contribution plan.12
[321]*321II. PROCEDURAL HISTORY
Plaintiffs argue that SERA retirement benefits are “rates of compensation” or, alternatively, “conditions of employment,” as these terms are used in Const 1963, [322]*322art 11, § 5. Accordingly, plaintiffs claim, SERA retirement benefits are not subject to legislative change because the regulation of “rates of compensation” and “conditions of employment” of employees in the classified civil service is within the exclusive and plenary authority of the commission.
The Court of Claims held that 2011 PA 264 was unconstitutional. The Court of Appeals affirmed the ruling of the Court of Claims, concluding that SERA retirement benefits are properly classified as both “rates of compensation” and “conditions of employment,” neither of which is subject to legislative alteration.13 The state appealed and we granted leave, directing the parties to brief “whether 2011 PA 264 is unconstitutional, in whole or in part, in violation of Const 1963, art 11, § 5.”14
III. STANDARD OF REVIEW
This Court reviews the grant or denial of summary disposition de novo.15 Questions of constitutional and statutory interpretation also are reviewed de novo.16
IV. ANALYSIS
As noted, plaintiffs make two alternative arguments that by enacting 2011 PA 264, the Legislature infringed the commission’s constitutional authority. First, plaintiffs allege that the pension accrual characteristics altered by 2011 PA 264 affect classified employees’ “rates of compensation” under Const 1963, art [323]*32311, § 5, and that the Legislature cannot act in that area. Second and in the alternative, plaintiffs allege that the pension accrual characteristics affected by 2011 PA 264 are “conditions of employment” under Const 1963, art 11, § 5. We address these two arguments in turn.
A. “RATES OF COMPENSATION”
As used in Article 11, § 5, we conclude that the term “rates of compensation” was not understood by the ratifiers of the 1963 constitution to include fringe benefits such as pensions; rather, the common understanding of the term at that time was that it included only salaries and wages.
Our primary goal in construing a constitutional provision is to give effect to the intent of the people of the state of Michigan who ratified the Constitution, by applying the rule of “common understanding.”17 We locate the common understanding of constitutional text by determining the plain meaning of the text as it was understood at the time of ratification.18 Interpretation of a constitutional provision also takes account of “the circumstances leading to the adoption of the provision and the purpose sought to be accomplished.”19 The Address to the People, which was dis[324]*324tributed to Michigan citizens in advance of the ratification vote and which explained in everyday language what each provision of the proposed new Constitution was intended to accomplish,20 and, to a lesser degree, the constitutional convention debates are also relevant to understanding the ratifiers’ intent.21
Textual indicators in the Constitution uniformly indicate that the phrase “rates of compensation,” as used in Article 11, § 5, was commonly understood to include only salaries and wages, i.e., amounts paid out to employees in a paycheck.22 For instance, Article 11, § 5 only reserves to the commission the authority to “fix rates of compensation,” rather than “compensation” generally. In the context of compensation for one’s employment-related services, “rate” was defined as “a wage paid on a specified time basis: a salary figured on an hourly rate.”23 “Wages,” in turn, was defined as [325]*325“money that is paid or received for work or services, as by the hour, day, or week”24
This understanding is confirmed elsewhere. Highly significant to our assessment is the Address to the People. Apart from the text of the Constitution itself, the Address provides an authoritative contemporary construction of the constitutional provisions that the citizens of Michigan were asked to vote on.25 The Address confirms that “rates of compensation” did not include fringe benefits such as pensions. As previously stated, the current ¶ 7 of Article 11, § 5 gives the Legislature a supermajority veto over the commission’s proposed changes to “rates of compensation.” The Address explains that this provision “provides for limited legislative control of wage increases under specified circumstances.”26 The Address alternatively explains the same legislative control as pertaining to “the total level of state payroll[.]”27 “Compensation” was thus directly understood as the money employees received in their paychecks.
Moreover, the portion of the Address explaining Article 11, § 5 states: “Of special interest to civil service personnel is the provision in Sec. 24, Article IX, of the proposed constitution which specifies that pension plans and retirement systems of the state shall be contractual obligations ‘which shall not be diminished [326]*326or impaired.’ ”28 The ratifiers were thus aware of the special independent status of pensions created for civil servants, as well as the new obligation imposed to protect any such pensions. This portion of the Address is especially noteworthy because, in discussing ¶ 4 of Article 11, § 5, the Address directs the ratifiers’ attention elsewhere to the provisions of Article 9, § 24 that expressly discuss pensions, while simultaneously equating “rates of compensation” with wages. We conclude that this explanation confirms our textual construction based on the common understanding of “rates of compensation.”
Finally, although of lesser import than the Address, the transcript of the constitutional convention debates further confirms that the common understanding of “rates of compensation” did not extend to pensions. The record is replete with references to “wages” and “salaries” during discussion of the Legislature’s then-proposed veto power over commission increases to “rates of compensation,”29 and there are no relevant references to “pensions” or “retirement.”
In conjunction with the text of Article 11, § 5 discussed earlier, these historical sources confirm that the [327]*327phrase “rates of compensation” referred to salaries and wages as opposed to fringe benefits such as the SERA pension program. Accordingly, we find no merit in plaintiffs’ argument that 2011 PA 264 infringes the commission’s authority to regulate “rates of compensation,” because the SERA pension program does not affect “rates of compensation” as that term is used in Const 1963, art 11, § 5.
Notably, 2011 PA 264 does nothing to change the member’s salary or wages.30 With regard to overtime, 2011 PA 264 does not affect the availability of overtime, or the rate at which overtime is paid; it only affects how overtime factors into a member’s pension formula.31 Accordingly, because 2011 PA 264 does not affect “rates of compensation” by requiring changes to wages or salaries, it does not implicate the commission’s constitutional authority over classified civil servants’ “rates of compensation.”
B. "CONDITIONS OF EMPLOYMENT”
As an alternative to their argument that SERA pensions are “rates of compensation,” plaintiffs allege that SERA pensions are “conditions of employment.” They further allege that, as a result, any legislative action in the field of pensions requires commission approval in order to be constitutional. Plaintiffs also appear to allege that SERA was itself an “exercise” of commission authority.32 For the limited purpose of this [328]*328case, we assume without deciding that a pension is a “conditionQ of employment” as used in ¶ 4 of Const 1963, art 11, § 5. Furthermore, for the limited purpose of this case, we also assume without deciding that the commission’s authority under Article 11, § 5 to “regulate all conditions of employment” includes the authority to establish, maintain, and amend a pension plan.33 Regardless, we hold that the commission has no authority to prevent the Legislature from enacting 2011 PA 264 any more than it had authority to compel the enactment of SERA itself because either act would constitute an unconstitutional exercise of legislative authority.
1. THE COMMISSION LACKS POWER TO ENACT OR REVISE LEGISLATION
“The powers of government are divided into three branches: legislative, executive and judicial.”34 Although the commission is constitutionally created, and its proper functions are therefore constitutionally in[329]*329violable, the commission’s authority is part of the executive branch power.35 The commission “is vested with plenary powers in its sphere of authority.”36 Just as “any executive, legislative or judicial attempt at incursion into that ‘sphere’ would be unavailing,”37 the commission itself may not act outside the bounds of its authority.38 The Legislature—responsible for creating 2011 PA 264—and the commission are each constitutionally precluded from exercising the powers of the other: “No person exercising powers of one branch shall exercise powers properly belonging to another branch except as expressly provided in [the] constitution.”39
It scarcely bears repeating that the executive power cannot be used to enact actual statutes. That power is [330]*330vested exclusively in the Legislature.40 Likewise, the commission cannot mandate certain appropriations relating to conditions of employment, because the appropriative power also resides in the Legislature.41 That said, it is true that the separation of powers doctrine does not rigidly confine all powers of a certain character to one branch or another. One branch of government may have authority of a character typically associated with another branch, as long as the Constitution “explicitly” grants that authority.42 A compelling example in this context is Const 1963, art 11, § 5, ¶ 7, which provides the commission with the express authority to increase rates of compensation. Such increased rates must be included within the budget submitted by the Governor and are subject only to the supermajority veto of the Legislature. This is a singular, if limited, nonlegislative power to allocate taxpayer funds. This explicitly granted power stands in contrast to the absence of such power with respect to regulating conditions of employment. Article 11, § 5 cannot bear an interpretation that the ratifiers allocated any legislative or appropriative authority to the commission to regulate “conditions of employment.” Whatever the bounds of the commission’s authority to [331]*331increase rates of compensation, the Constitution gives the commission no comparable power to expend taxpayer funds in connection with its power to “regulate conditions of employment.”
By the same logic, the commission has no explicit authority to require the Legislature to exercise its lawmaking power in the field of “conditions of employment.” Under plaintiffs’ interpretation of the constitutional provision at issue, the commission’s power in this area would be so limitless as to include the authority for it to dictate the nuances of statutory schemes. Plaintiffs’ argument that the commission has such authority must fail. Instead, when the commission wishes to regulate “conditions of employment,” it must proceed within its own sphere, using its own constitutionally provided tools, which it typically does by promulgating and enforcing its rules.
2. 2011 PA 264 DOES NOT VIOLATE THE COMMISSION’S CONSTITUTIONAL AUTHORITY
Based on the foregoing, we hold that SERA could not have been, and thus is not, a product that the commission could have created by exercising its proper constitutional authority. These principles are equally relevant in considering whether the Legislature has overstepped its bounds and intruded into the sphere of the commission’s constitutional responsibility. Unlike the federal Constitution, our Constitution is “not a grant of power to the Legislature, but is a limitation upon its powers.”43 Therefore, the legislative authority of the state “can do anything which it is not prohibited [332]*332from doing by the people through the Constitution of the State or the United States.”44
The commission has plenary, exclusive authority to “regulate all conditions of employment in the classified service.”45 As mentioned earlier, we assume without deciding that pensions are such “conditions of employment” and that the commission’s authority under Article 11, § 5 to “regulate all conditions of employment” includes the authority to establish, maintain, and amend its own pension plan.46 We also assume without deciding that the commission’s Article 11, § 5 authority to “regulate all conditions of employment” is exclusive and not subject to the Legislature’s authority in Article 4, § 1 to exercise “[t]he legislative power of the State of Michigan” or its authority in Article 4, § 49 to “enact laws relative to . . . conditions of employment.” If that is the case, then SERA in its entirety is a legislative intrusion into the commission’s sphere of authority to “regulate all conditions of employment,” by virtue of the fact that it dictates an element of a condition of employment.47 However, it is important to note that, in amending SERA by enacting 2011 PA 264, the Legislature has no more encroached upon the commission’s authority to regulate pensions than it had before the amendment.
[333]*333When confronted with a violation of the separation of powers, this Court has noted that it is permissible for one branch to acquiesce in the intrusion of another and thus avoid a constitutional conflict.48 Here, the commission acquiesced in the Legislature’s presumed violation of the separation of powers when it made SERA applicable to civil servants in Rule 5-13, which provides that “[a] classified employee is eligible for retirement benefits as provided by law.”49 And Rule 5-13, last amended effective March 18, 2001, was in place when the Legislature enacted 2011 PA 246. Thus, upon enactment, the amendment necessarily became [334]*334part of the “retirement benefits as provided by law” applicable to classified civil servants.
Furthermore, the dissent rightly states that “there is a meaningful difference between an assertion that the commission has the power to dictate what the Legislature enacts into law and an assertion that the commission is empowered to object to a legislative incursion into the commission’s sphere of authority.”50 Here, both are occurring simultaneously, because plaintiffs object to the amended SERA and demand the reinstatement of the preamendment SERA. But that prior version of the law no longer exists.
We merely hold that the commission may adopt rules that acquiesce in a statute that allegedly intrudes on its sphere of authority, as it has here. What plaintiffs seek in this appeal appears to be beyond the power of the commission. The commission cannot decline to acquiesce by directing the Legislature to “revive” an act that no longer exists. And what the commission cannot constitutionally do directly, it cannot, through surrogates or otherwise, accomplish indirectly by resort to the judiciary.51
V. CONCLUSION
Const 1963, art 11, § 5 vests the Civil Service Commission with plenary authority to “fix rates of compen[335]*335sation” and “regulate all conditions of employment [.]” The Legislature, by 2011 PA 264, amended SERA, which provides pensions to state employees, including those in the classified civil service. 2011 PA 264 does not infringe the commission’s authority to “fix rates of compensation” because the ratifiers did not understand that phrase to include pensions or other fringe benefits. Likewise, when the commission acquiesces in the application of SERA to employees in the classified civil service, the presumed infringement of 2011 PA 264 presents no constitutional problem. The commission’s authority to regulate does not permit the commission to enact, amend, or maintain the laws of this state.
We reverse the Court of Appeals and remand to the Court of Claims for further proceedings not inconsistent with this opinion.
