    and JUSTICE TIMMER joined.
    JUSTICE BRUTINEL, opinion of the Court:
    ¶1            Arizona Revised Statutes Section 38-818 establishes a
    formula for calculating pension benefit increases for retired members of
    the Elected Officials’ Retirement Plan (“Plan”). In 2011, the legislature
    modified that formula by enacting Senate Bill (“S.B.”) 1609. Because that
    statute diminishes and impairs the retired members’ benefits, we hold that
    it violates the Pension Clause of Article 29, § 1(C) of the Arizona
    Constitution.
    2
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    I.
    ¶2             In 1985, the Arizona Legislature established the Elected
    Officials’ Retirement Plan to provide pension benefits for elected officials,
    including judges. A.R.S. §§ 38-801(15), 38-802, 38-804. The Plan is funded
    by employer and employee contributions, court fees, and investment
    proceeds. Id. § 38-810.
    ¶3             Upon retirement, Plan members receive monthly benefits
    based on 4% of their salary for each year worked, up to a maximum of
    80% of their average yearly salary.1 Id. § 38-808(B)(1). Plan members are
    also eligible for additional financial benefits such as medical subsidies, id.
    § 38-817, disability benefits, id. § 38-806, survivor benefits, id. § 38-807, and
    benefit increases after retirement, id. § 38-818.
    ¶4             The benefit increase formula in § 38-818 is similar to a cost-
    of-living adjustment. But unlike a cost-of-living adjustment, which is
    generally tied to the inflation rate, see Strunk v. Pub. Emps. Ret. Bd., 
    108 P.3d 1058
    , 1070 (Or. 2005), the benefit increase in § 38-818 is not tied to
    inflation, but instead is tied to the Plan’s return on investment. A benefit
    increase is determined by multiplying the amount by which the yearly
    total investment return exceeds 9% times the actuarial present value of
    pensions in payment status, subject to a statutory cap of 4%. A.R.S. § 38-
    818(B)–(C), (F). Any return in excess of the amount necessary to pay for
    the benefit increase in any given year is placed in a reserve fund to be
    used for future benefit increases, including years in which the return itself
    is not sufficient to provide an increase. Id. § 38-818(E).
    ¶5           When the Plan was created, no statutory mechanism for
    awarding post-retirement benefit increases existed; instead, the legislature
    passed ad hoc increases. See A.R.S. § 38, Ch. 5, Art. 3, Elected Officials’
    Retirement Plan (Historical and Statutory Notes). In 1990, the legislature
    enacted A.R.S. § 38-818, creating the first statutory mechanism for
    1      In 2011, the legislature modified this formula for those who become
    Plan members after January 1, 2012. Those members receive monthly
    benefits based on 3% of their salary per year up to a maximum of 75% of
    their average yearly salary. A.R.S. § 38-808(C)(1).
    3
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    calculating increases. This statute provided that retired members are
    “entitled to receive a permanent increase in the base benefit” each year as
    determined by the statutory formula, but was effective only through 1994.
    Id. § 38-818(A) (1990). There was no benefit increase mechanism for 1995.
    ¶6            In 1996, the legislature removed the 1994 sunset provision,
    extending the permanent benefit increases indefinitely. Id. § 38-818 (1996).
    The legislature also reduced the annual benefit increase to the lesser of
    one-half of the percentage change in the consumer price index or 3%. Id.
    § 38-818(F). In 1998, the legislature amended § 38-818 to reinstate the 4%
    benefit increase cap. Id. § 38-818(F) (1998).
    ¶7          Later that year, Proposition 100 was referred to and passed
    by the voters, becoming Article 29 of the Arizona Constitution. It
    provides:
    A.     Public retirement systems shall be funded with
    contributions and investment earnings using actuarial
    methods and assumptions that are consistent with
    generally accepted actuarial standards.
    B.     The assets of public retirement systems,
    including investment earnings and contributions, are
    separate and independent trust funds and shall be
    invested, administered and distributed as determined
    by law solely in the interests of the members and
    beneficiaries of the public retirement systems.
    C.     Membership in a public retirement system is a
    contractual relationship that is subject to article II, §
    25, and public retirement system benefits shall not be
    diminished or impaired.
    Ariz. Const. art. 29, § 1.
    ¶8              Beginning in 2000, the ratio of the Plan’s assets to its
    liabilities (“funding ratio”), began to steadily decline. 2 Staff of PSPRS,
    2       The funding ratio measures a pension plan’s assets as a percentage
    of its future obligations. See generally Richard A. Ippolito, Reversion Taxes,

    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    Comprehensive Annual Financial Report/Elected Officials’ Retirement Plan FY
    2010 at 7, available at http://azmemory.azlibrary.gov/cdm/singleitem/
    collection/statepubs/id/12803/rec/1. Between 2000 and 2010, the Plan’s
    funding ratio decreased from 141.7% to 66.7%. Id. Nevertheless, the
    reserve fund allowed retired members to receive a 4% benefit increase
    each year until 2011.
    ¶9            In 2011, the legislature enacted S.B. 1609, the provision at
    issue here. S.B. 1609 amended § 38-818 by prohibiting the transfer of any
    investment earnings that exceed the 9% rate of return to the reserve fund,
    and instead provided that such earnings would fund the basic retirement
    plan. 3 2011 Ariz. Sess. Laws ch. 357, § 62(A), (D). As a result, retired Plan
    members received only a 2.47% benefit increase in July 2011 (rather than
    the anticipated 4% increase) and did not receive any benefit increases in
    2012 or 2013.
    ¶10            Effective July 1, 2013, S.B. 1609 also changed the formula
    used to calculate permanent benefit increases. A.R.S. § 38-818.01(B). This
    new formula increased the rate of return necessary to trigger a benefit
    increase from 9% to 10.5%. Id. § 38-818.01(D). The new formula also tied
    the availability of benefit increases to the Plan’s overall funding ratio. Id.
    § 38-818.01(C). If the funding ratio is 60% or less, the Plan will not fund a
    benefit increase; if the funding ratio is between 60% and 65%, the Plan will
    fund a 2% benefit increase; and for each 5% increase in the funding ratio
    over 65%, the Plan will increase the amount of the benefit increase by 0.5%
    up to a maximum of 4%. Id. Beginning December 31, 2015, S.B. 1609
    allows the legislature to provide ad hoc benefit increases in addition to the
    permanent benefit increases that may be awarded each year. Id. § 38-
    818.02.

    199, 202 (2001).
    3      Although S.B. 1609 became effective on July 20, 2011, the legislature
    made it retroactive to May 31, 2011, in order to reverse the July 1, 2011
    transfer of excess investment earnings to the reserve fund.

    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    behalf of themselves and as representatives of a class of retired Plan
    members and beneficiaries (collectively “Fields”), sued the Elected
    Officials’ Retirement Plan and its board members (“EORP”), alleging that
    S.B. 1609 violates Article 29, § 1, as well as Article 2, § 25 of the Arizona
    Constitution, and Article 1, § 10 of the United States Constitution, both of
    which prohibit the enactment of laws impairing contract obligations. The
    State intervened to defend S.B. 1609. Fields moved to preliminarily enjoin
    implementation of S.B. 1609, and the trial court consolidated the hearing
    on the preliminary injunction with a trial on the merits. Following the
    trial, the court found that S.B. 1609 violates Article 29, § 1(C)’s command
    that “public retirement system benefits shall not be diminished or
    impaired.” The court reasoned that § 38-818’s required benefit increase
    was a vested financial benefit that was directly and adversely affected by
    S.B. 1609. The court did not address Fields’ contentions that S.B. 1609
    violated the Contract Clauses of the state and federal constitutions. The
    court also awarded Fields attorneys’ fees.
    ¶12            After EORP filed a timely notice of appeal, we granted
    EORP’s petition to transfer the case to this Court under Arizona Rule of
    Civil Appellate Procedure 19(a). The funding of public pensions raises
    issues of statewide importance, and we have jurisdiction pursuant to
    Article 6, § 5(3) of the Arizona Constitution.
    II.
    ¶13           Before we begin our analysis of the legal question presented,
    we note that the Justices of this Court are not members of the class of
    retired judges who are appellees in this case. We are, however, members
    of the Plan, as are most Arizona state judges, and we will be eligible for
    benefit increases pursuant to A.R.S. § 38-818 upon our retirement. 4 No
    4      New enrollment in the Plan ended after 2013. Beginning January 1,
    2014, all new Arizona elected officials, including judges, are members of
    the newly created Elected Official’s Defined Contribution Retirement
    System plan. A.R.S. § 38-831(4). They are not eligible for benefit increases
    pursuant to A.R.S. § 38-818. Elected officials and judges who were
    members of the Plan on December 31, 2013, are eligible to remain in the
    Plan. A.R.S. § 38-804(B).
    6
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    party has asked for our recusal, and, in any event, the rule of necessity
    applies.
    ¶14           The rule of necessity establishes that a judge is not
    disqualified because of a personal interest if no other judge is available to
    decide the case. United States v. Will, 
    449 U.S. 200
    , 213–16 (1980); see also
    Scheehle v. Justices of the Sup. Ct., 
    211 Ariz. 282
    , 295, 
    120 P.3d 1092
    , 1105
    (2005). Because our disqualification would “result in a denial of a
    litigant’s constitutional right to have a question, properly presented to
    such court, adjudicated,” Will, 
    449 U.S. at 214
     (quotation omitted), the rule
    of necessity applies, and we must decide the matter, Wisconsin Judicial
    Com’n v. Prosser, 
    817 N.W.2d 830
    , 833 (Wis. 2012).
    III.
    ¶15            We review the constitutionality of S.B. 1609 de novo. State v.
    Glassel, 
    211 Ariz. 33
    , 51 ¶ 65, 
    116 P.3d 1193
    , 1211 (2005). We presume that
    the statute is constitutional, and a “party asserting its unconstitutionality
    bears the burden of overcoming the presumption.” Eastin v. Broomfield,
    
    116 Ariz. 576
    , 580, 
    570 P.2d 744
    , 748 (1977).
    IV.
    A.
    ¶16            We first address the argument that because Article 29, § 1(C)
    references the Contract Clause of Article 2, § 25 of the Arizona
    Constitution, we should resolve this case by using a Contract Clause
    analysis similar to that employed by the Supreme Court in Energy Reserves
    Group, Inc. v. Kansas Power & Light Co., 
    459 U.S. 400
     (1983), which held that
    although the federal Contract Clause is facially absolute, it allows the
    impairment of contracts under certain conditions. Section 1(C) not only
    references the Contract Clause, but also uses similar language. Compare
    Ariz. Const. art. 29, § 1(C) (“Membership in a public retirement system is a
    contractual relationship that is subject to article II, § 25, and public
    retirement system benefits shall not be diminished or impaired.”), with
    Ariz. Const. art. 2, § 25 (“No . . . law impairing the obligation of a contract,
    shall ever be enacted.”). But accepting this argument would render
    7
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    superfluous the latter portion of § 1(C), the Pension Clause, which
    prohibits diminishing or impairing public retirement benefits. Because
    the legislature generally avoids redundancy, we reject this argument.
    Williams v. Thude, 
    188 Ariz. 257
    , 259, 
    934 P.2d 1349
    , 1351 (1997) (noting
    court construes statutes to avoid rendering portions superfluous); Vega v.
    Morris, 
    184 Ariz. 461
    , 463, 
    910 P.2d 6
    , 8 (1996) (rejecting an interpretation
    that would render the statute in question “essentially meaningless”).
    ¶17           We similarly reject EORP’s argument that reading the two
    clauses of § 1(C) independently renders the reference to the Contract
    Clause redundant. The Contract Clause applies to the general contract
    provisions of a public retirement plan, while the Pension Clause applies
    only to public retirement benefits. Therefore, the Pension Clause confers
    additional, independent protection for public retirement benefits separate
    and distinct from the protection afforded by the Contract Clause. See
    Ariz. Op. Att’y Gen. No. I09-009 (concluding that the Pension Clause
    “provides additional, substantive protection” to that offered by the
    Contract Clause).
    B.
    ¶18            We next consider whether use of the formula established by
    A.R.S. § 38-818 to calculate future benefit increases is itself a “benefit”
    protected by the Pension Clause. Fields argues that the term “benefit”
    includes the benefit-increase formula. The State and EORP, on the other
    hand, argue that the term “benefit” only includes the right to receive
    payments in the amount determined by the most recent calculation. All
    parties agree that once a benefit increase has occurred, the Pension Clause
    protects it from later reduction.
    ¶19             In interpreting a constitutional amendment, our primary
    purpose is to “effectuate the intent . . . of the electorate that adopted it.”
    Jett v. City of Tucson, 
    180 Ariz. 115
    , 119, 
    882 P.2d 426
    , 430 (1994); see also
    McElhaney Cattle Co. v. Smith, 
    132 Ariz. 286
    , 289, 
    645 P.2d 801
    , 804 (1982).
    Neither the Arizona Constitution nor Arizona case law defines “benefit.”
    We therefore consider how this term “is generally understood and used
    by the people.” McElhaney Cattle Co., 
    132 Ariz. at 290
    , 
    645 P.2d at 805
    ; see
    also State v. Jones, 
    188 Ariz. 388
    , 392, 
    937 P.2d 310
    , 314 (1997) (when a term
    8
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    is not defined within a statute, “the court first looks to the statute’s
    language”). We first examine the provision by assigning each word its
    “natural, obvious, and ordinary meaning.” State ex rel. Morrison v.
    Nabours, 
    79 Ariz. 240
    , 245, 
    286 P.2d 752
    , 755 (1955).
    ¶20            To determine the ordinary meaning of a term, we commonly
    refer to established and widely used dictionaries. State v. Wise, 
    137 Ariz. 468
    , 470 n.3, 
    671 P.2d 909
    , 911 n.3 (1983). In the retirement-system context,
    a “benefit” has been defined as “a payment or service provided for under
    an annuity, pension plan, or insurance policy.” Merriam-Webster’s
    Collegiate Dictionary 114 (11th ed. 2003); see also The American Heritage
    Dictionary 168 (5th ed. 2011) (defining “benefit” as “a form of
    compensation, such as . . . a pension, provided to employees in addition to
    wages or salary as part of an employment arrangement”).
    ¶21           We think the dictionary definitions do not determine the
    meaning of “benefit” as used in the Pension Clause. The parties’ differing
    interpretations each are reasonable, and the dictionary definitions do not
    provide sufficient guidance as to whether a “benefit” constitutes only the
    base benefit or includes the promise of future benefit increase payments
    using a specified formula.
    ¶22           When terms are unclear or susceptible to more than one
    reasonable interpretation, we consider extrinsic evidence of the
    electorate’s intent, including “the history behind the provision, the
    purpose sought to be accomplished by its enactment, and the evil sought
    to be remedied.” McElhaney Cattle Co., 
    132 Ariz. at 290
    , 
    645 P.2d at 805
    .
    ¶23           The history of the Pension Clause suggests that the term
    “benefit” includes benefit increases. In 1990, eight years before the voters
    approved the Pension Clause, the legislature enacted A.R.S. § 38-818,
    which provides that eligible retired members are “entitled to receive [a]
    permanent benefit increase in their base benefit.” (Emphasis added).
    After this version of § 38-818 sunsetted in 1994, the legislature removed
    the sunset provision in 1996 — unqualifiedly extending benefit increases
    in perpetuity. A.R.S. § 38-818 (1996). Just two years later, the legislature
    reinstated the 4% benefit increase cap, and the voters approved Article 29,
    of which the Pension Clause is a part, giving public retirement benefits
    9
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    constitutional protection.
    ¶24           The Pension Clause neither altered the concept of “benefit”
    reflected in § 38-818’s “entitled to receive a permanent benefit increase”
    language, nor amended the formula for the calculation of pensions.
    Inasmuch as formula-based future benefit increases were part of the
    statutorily identified benefits existing in 1998, it seems reasonable to
    conclude that they also were embraced by the term “benefits” in the
    Pension Clause.
    ¶25            We disagree with the State’s and EORP’s argument that
    because § 38-818 prescribes only a formula for benefit increases rather
    than a liquidated amount, that formula is not protected by the Pension
    Clause. The monthly payments to which a retired Plan member is entitled
    are determined by a statutory formula. See A.R.S. § 38-808(B), (C) (2011);
    A.R.S. § 38-818(A) (1996). Although the State seeks to limit the definition
    of “benefit” to the “liquidated amount” of payments as currently
    calculated, the legislature has never promised to pay a specific dollar
    amount; rather, it has provided a formula by which the promised amount
    is calculated. See id.
    ¶26          Adopting this reasoning would place § 38-808’s base benefit
    — the main component of retirement benefits — outside the scope of
    Pension Clause protection because the base benefit is a direct product of §
    38-808’s formula. As the legislature demonstrated when it passed S.B.
    1609, changing the amount of the promised benefit requires changing the
    formula. Therefore, the “benefit” provided under § 38-808, and protected
    by the Pension Clause, necessarily includes the right to use the statutory
    formula.
    ¶27           Our interpretation of the Pension Clause is consistent with
    prior cases. In Yeazell v. Copins, this Court held that an employee was
    entitled to have his retirement benefits calculated based upon the formula
    existing when he began employment, rather than a less-favorable formula
    subsequently adopted during his employment. 
    98 Ariz. 109
    , 115, 
    402 P.2d 541
    , 545 (1965). The Court explained that the employee “had the right to
    rely on the terms of the legislative enactment of the Police Pension Act of
    1937 as it existed at the time he entered the service of the City of Tucson
    10
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    and that the subsequent legislation may not be arbitrarily applied
    retroactively to impair the contract.” 
    Id. at 117
    , 
    402 P.2d at 549
    . As in
    Yeazell, Fields has a right in the existing formula by which his benefits are
    calculated as of the time he began employment and any beneficial
    modifications made during the course of his employment. Thurston v.
    Judges’ Ret. Plan, 
    179 Ariz. 49
    , 51, 
    876 P.2d 545
    , 574 (1994) (recognizing that
    “when the amendment [to retirement benefits] is beneficial to the
    employee or survivors, it automatically becomes part of the contract by
    reason of the presumption of acceptance”).
    ¶28            This definition of “benefit” also comports with the use of the
    term in other states that have similar constitutional provisions protecting
    public pension benefits. For example, construing a similar definition of
    “benefit,” New York and Illinois have also determined that benefit
    calculation formulas are entitled to constitutional protection. 5          See
    Kleinfeldt v. New York City Emps.’ Ret. Sys., 
    324 N.E.2d 865
    , 868–69 (N.Y.
    1975) (including the formula utilized in calculating an annual retirement
    allowance under the Pension Clause); Miller v. Ret. Bd. of Policemen’s
    Annuity, 
    771 N.E.2d 431
    , 444 (Ill. App. 2001) (holding benefit increases to
    be constitutionally protected). Additionally, unlike narrower protections
    found in other states’ constitutions, the protection afforded by the Arizona
    Pension Clause extends broadly and unqualifiedly to “public retirement
    system benefits,” not merely benefits that have “accrued” or been
    “earned” or “paid.” See, e.g., Alaska Const. art. 7, § 7; Haw. Const. art. 16,
    § 2; Mich. Const. art. 9, § 24.
    ¶29            Accordingly, we conclude that § 38-818’s benefit increase
    formula is a “benefit” for purposes of Article 29, § 1(C).
    5      New York’s Pension Clause provides: “[M]embership in any
    pension or retirement system of the state or of a civil division thereof shall
    be a contractual relationship, the benefits of which shall not be diminished
    or impaired.” N.Y. Const. art. 5, § 7. Illinois’ Pension Clause provides:
    “Membership in any pension or retirement system of the State, any unit of
    local government or school district, or any agency or instrumentality
    thereof, shall be an enforceable contractual relationship, the benefits of
    which shall not be diminished or impaired.” Ill. Const. art. 13, § 5.

    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    C.
    ¶30           The State and EORP argue that retired judges do not have a
    vested right in the formula because it is contingent upon future events —
    for example, a rate of return sufficient to trigger the benefit increase.
    “[Benefits] are contingent when they are only to come into existence on an
    event or condition which may not happen or be performed until such
    other event may prevent their vesting.” Thurston, 
    179 Ariz. at 50
    , 
    876 P.2d at 548
     (quoting Hall v. A.N.R. Freight System, Inc., 
    149 Ariz. 130
    , 140, 
    717 P.2d 434
    , 444 (1986)).
    ¶31            In Yeazell, this Court held that because Article 9, § 7 of the
    Arizona Constitution forbids the legislature from providing gratuities, the
    right to receive a pension necessarily arose as a condition of the
    employee’s contract of employment. 
    98 Ariz. at 114
    , 
    402 P.2d at 544
    .
    Although the right to receive a pension is subject to conditions precedent,
    such as completing the term of employment, “the right to a pension
    becomes vested upon acceptance of employment.” 
    Id. at 115
    , 
    402 P.2d at 545
    ; see also Fund Manager v. City of Phoenix Police Dept., 
    151 Ariz. 487
    , 489,
    
    728 P.2d 1237
    , 1239 (App. 1986) (stating that “a public employee’s interest
    in a retirement benefit or pension is so significant that it should become a
    right or entitlement at the outset of employment”). After such vesting,
    “[the pension] contract cannot be unilaterally modified nor can one party
    to a contract alter its terms without the assent of the other party.” Yeazell,
    
    98 Ariz. at 115
    , 
    402 P.2d at 545
    . This contractual underpinning of public
    retirement systems was codified by Article 29, §1(C). Because future
    increases under § 38-818 fall within the meaning of “benefit” under Article
    29, they are part of the contract of employment and are not contingent.
    ¶32            EORP relies on Smith v. City of Phoenix, 
    175 Ariz. 509
    , 
    858 P.2d 654
     (App. 1992), to argue that Fields had only a contingent right. In
    Smith, a city ordinance set the salaries of city judges at 95% of the salaries
    of superior court judges. Before a statutory increase in superior court
    salaries took effect, the city revised its ordinance to preserve the salaries
    for city judges at the then-existing amount. 
    Id. at 514
    , 
    858 P.2d at 659
    .
    The court of appeals held that Smith had no vested contractual right to
    continued salary increases under the city ordinance, observing that his
    “contract of employment” did not express “that the method of calculating
    12
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    his salary would remain fixed throughout his term,” and “[i]ndeed, the
    fact that both parties knew his salary was established by a city ordinance,
    which was naturally subject to change by the city council, suggests just the
    opposite.” 
    Id.
    ¶33            Smith is inapposite. Assuming the case was correctly
    decided, we note that it reflects the general principle that statutory
    provisions do not create contractual rights. See Proksa v. Ariz. State Sch. for
    the Deaf & the Blind, 
    205 Ariz. 627
    , 629 ¶¶11–12, 
    74 P.3d 939
    , 941 (2003).
    But statutorily established retirement benefits are an exception to this rule.
    
    Id.
     at 631 ¶21, 
    74 P.3d at 943
    . Under Yeazell, the right to a public pension
    on the terms promised vests upon acceptance of employment, 
    98 Ariz. at 115
    , 
    402 P.2d at 545
    , and “the State may not impair or abrogate that
    contract without offering consideration and obtaining consent of the
    employee,” Proksa, 
    205 Ariz. at
    630 ¶ 16, 
    74 P.3d at 942
    ; cf. Thurston, 
    179 Ariz. at 52
    , 
    876 P.2d at 575
     (recognizing that a detrimental modification to
    retirement benefits “may not be applied absent the employee’s express
    acceptance of the modification because it interferes with the employee’s
    contractual rights”).
    D.
    ¶34          This leaves the question of whether S.B. 1609’s changes to §
    38-818’s formula diminish or impair retirement system benefits. We
    conclude that S.B. 1609 diminishes retired members’ retirement benefits in
    two ways.
    ¶35            First, because S.B. 1609 retroactively prevented the transfer
    of approximately $31 million to the reserve, 2011 Ariz. Sess. Laws, Ch. 357,
    § 62(A), (D), the Plan could fund only a 2.47% benefit increase in 2011,
    rather than the expected 4% increase. Likewise, because S.B. 1609
    prevented any transfer for 2012 or 2013 and the reserve did not have
    sufficient funds, retired members did not receive a benefit increase in
    those years. Compare id. § 62(A) (eliminating any transfer of excess
    investment earnings from and after May 31, 2011), with A.R.S. § 38-
    818.01(A) (establishing a new benefit increase formula effective July 1,
    2013). If S.B. 1609 had not been enacted, Fields would have received a 4%
    benefit increase in 2011, 2012 and 2013.
    13
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    ¶36           Second, S.B. 1609 makes it more difficult for retired members
    to receive future benefits by increasing the rate of return required to fund
    an increase from 9% to 10.5%. S.B. 1609 also makes it less likely that
    retired members will receive the maximum 4% increase in benefits by
    tying increases to the Plan’s funding ratio. Because S.B. 1609 diminishes
    and impairs the benefits to which retired members are entitled, the statute
    violates Article 29, § 1(C).
    E.
    ¶37           We likewise reject the State’s and EORP’s argument that
    Section 1(C)’s pension protection is subject to Section 1(A)’s requirement
    that the plan be funded “using actuarial methods and assumptions that
    are consistent with generally accepted actuarial standards.” Ariz. Const.
    art. 29 § 1(A). Section 1(C) explicitly states that “retirement system
    benefits shall not be diminished or impaired.” No language in Section
    1(C) indicates that its mandate is qualified by any other provision,
    including Section 1(A).
    V.
    ¶38          Fields has requested an award of attorneys’ fees under the
    common fund doctrine or A.R.S. § 12-2030, which permits fees to
    prevailing parties in mandamus actions.
    ¶39           A mandamus action “seeks to compel a public official to
    perform a non-discretionary duty imposed by law,” and a party that
    prevails in such an action is entitled to attorneys’ fees and other expenses
    under § 12-2030. Stagecoach Trails MHC, L.L.C. v. City of Benson, 
    231 Ariz. 366
    , 370 ¶¶ 18–19, 
    295 P.3d 943
    , 947 (2013).
    ¶40           Fields sought to compel EORP to calculate benefit increases
    according to § 38-818’s formula rather than that of S.B. 1609. Although
    Fields characterized the action as one for mandamus, the complaint
    alleges that the Board did not use the correct formula to calculate the
    benefit increases, not that it refused to calculate the benefit at all.
    Therefore, Fields did not seek mandamus relief. See Stagecoach Trails, 231
    Ariz. at 370 ¶ 21, 295 P.3d at 947 (holding that an action contending that
    14
    HON. FIELDS et al v. ELECTED OFFICIALS RETIREMENT PLAN
    Opinion of the Court
    an officer “either misapplied or misinterpreted the regulations” did not
    seek relief in the nature of mandamus). We thus deny Fields’ request for
    attorneys’ fees pursuant to § 12-2030.
    ¶41            Fields also argues that the common fund doctrine supports
    an award of attorneys’ fees. “Under the common fund doctrine a court
    may award attorneys’ fees to counsel for the prevailing side whose efforts
    in litigation create or preserve a common fund from which others who
    have undertaken no risk or cost will nevertheless benefit.” Kerr v. Killian,
    
    197 Ariz. 213
    , 217–18 ¶ 19, 
    3 P.3d 1133
    , 1137–38 (App. 2000). Because
    “application of [the common fund doctrine] is capable of great abuse, it is
    exercised only in exceptional circumstances and for dominating reasons of
    justice.” 
    Id.
     at 219–20 ¶ 27, 
    3 P.3d at
    1139–40 (quoting Rossi, Attorneys
    Fees, Second Edition (Lawyers Cooperative Publishing Co. 1995)). Even
    assuming that the doctrine may apply in a case such as this (an issue we
    need not decide), we decline to award attorneys’ fees in an exercise of our
    discretion.
    VI.
    ¶42          We affirm the decision of the trial court.
