    published     decision   of   the   court    of    appeals1       affirming       the

    The Honorable William S. Pocan presided.
    No.   2012AP2466
    and   declaratory       and      injunctive      relief   to     Suzanne     Stoker
    ("Stoker")3 and       her labor union, the            Wisconsin Federation of
    Nurses and Health Professionals, Local 5001, AFT, AFL–CIO ("the
    Federation").         The    suit   was    filed     against   the    respondents,
    Milwaukee County and the Milwaukee County Pension Board ("the
    Pension    Board").         We   reverse   and   remand   this    matter    to   the
    circuit court to dismiss the complaint.
    ¶2    Milwaukee County calculates pension payments for its
    retired    employees        by   multiplying     a   retiree's    final     average
    salary4 by a certain percentage known as a multiplier, and the
    resulting number is then multiplied by the retiree's total years
    of county service.           When Stoker's county service began, a 1.5%
    multiplier applied to her service.                   In 2000 Milwaukee County
    3
    Stoker filed this suit on behalf of all similarly situated
    Milwaukee County employees. References to Stoker will refer to
    this class of employees unless the context clearly indicates
    otherwise.
    4
    Milwaukee County, Wis. General Ordinance                       ("M.C.G.O.")
    § 201.24(2.8) (2000) provides in relevant part:
    Final average salary for a member whose continuous
    membership began after January 1, 1982, means the
    average annual earnable compensation for the five (5)
    consecutive years of service during which the member's
    earnable compensation was the highest, or, if he
    should have less than five (5) years of service, then
    his average annual earnable compensation during such
    period of service. However, when a member is employed
    by the state but paid partly by the county, his final
    average   salary  with   respect  to   any  period  of
    employment solely by the county shall be the average
    earnable compensation for the three (3) or five (5)
    consecutive years respectively of such service during
    which his earnable compensation was the highest.
    2
    No.   2012AP2466
    passed an ordinance that increased the multiplier from 1.5% to
    2% for service rendered on and after January 1, 2001.                             Milwaukee
    County, Wis. General Ordinance ("M.C.G.O.") § 201.24(5.15)(1)(a)
    (2000).5         In 2011, consistent with the terms of a collective
    bargaining        agreement      with      the     Federation,       Milwaukee       County
    passed an ordinance that reduced the multiplier from 2% to 1.6%
    for all county service performed on and after January 1, 2012,
    the       effective          date     of         the         ordinance.            M.C.G.O.
    § 201.24(5.1)(2)(f)           (2011).        The       2%    multiplier     continued    to
    apply to service rendered by Stoker from 2001 through 2011.
    ¶3        Stoker argues that this reduction of the multiplier is
    a breach of contract because she had a vested right to have the
    2% multiplier apply to her post-2011 county service and because
    she   did       not    personally     consent         to    the   reduction.      Milwaukee
    County      and       the   Pension   Board       argue       that   the    reduction    is
    authorized because Stoker had no vested right to have the 2%
    multiplier apply to her post-2011 county service. The Pension
    Board further argues that even if she had such a right, the
    Federation        lawfully      consented        to    the     reduction     on    Stoker's
    behalf     by     ratifying     the   collective            bargaining     agreement    that
    agreed to reduce the multiplier from 2% to 1.6% for post-2011
    service.
    5
    Technically, this ordinance provided a 0.5% multiplier in
    addition to the 1.5% multiplier that applied under M.C.G.O.
    § 201.24(5.1).   Thus, these two ordinances combined provided a
    2% multiplier.
    3
    No.     2012AP2466
    ¶4      We conclude that Milwaukee County did not breach the
    contract with Stoker when it amended the pension multiplier from
    2% to 1.6%.           The amendment did not breach Stoker's contractual
    right to retirement system benefits earned and vested because it
    had prospective-only application to future service credits not
    yet earned, specifically, on and after January 1, 2012.                              We
    conclude       that    the    legislature       preserved   Stoker's    rights      and
    benefits already accrued but also gave Milwaukee County home
    rule authority with the flexibility to enact such prospective-
    only changes.           We conclude that Stoker does not have a vested
    right to have the 2% multiplier apply to her then-unearned post-
    2011 service.           In other words, Milwaukee County could so amend
    the formula and apply it prospectively because that prospective
    application does not "diminish or impair" benefits accrued from
    service       credits     already   earned.         Because   we   conclude      that
    Milwaukee County did have the ability to make these prospective-
    only       reductions    of   the   multiplier      without   Stoker's      personal
    consent, we need not address whether the Federation lawfully
    consented, on Stoker's behalf, to the reduction.
    I.    FACTUAL BACKGROUND
    ¶5      The relevant facts are not in dispute.                   In 1937 the
    legislature      required      counties     with    populations    of     500,000    or
    more to develop retirement systems for their employees.                             Ch.
    201, Laws of 1937.6            Pursuant to this law, the Milwaukee County

    Section 1 of ch. 201, Laws of 1937 provided:
    (continued)
    4
    No.    2012AP2466
    Employees' Retirement System ("MCERS") was created on January 1,
    1938.     On   May   14,   1945,   the   legislature   required   employee
    benefits under MCERS to "be assured by benefit contracts."              Ch.
    138, Laws of 1945.7        The legislature also provided that "each
    RETIREMENT    SYSTEM    IN    POPULOUS   COUNTIES;
    DEFINITIONS.     In each county having a population of
    five hundred thousand or more a retirement system
    shall be established and maintained for the payment of
    benefits to the employes of such county and to the
    widows and children of such employes, except employes
    who    are   contributory   to,   participants  in,   or
    beneficiaries of a pension fund in operation in the
    state, or any municipal subdivision thereof.         The
    funds of the retirement system shall be derived,
    administered and disbursed in accordance with the
    provisions of this act.       Except where the context
    plainly requires a different meaning, the following
    words    and    phrases   shall   have    the  following
    meanings: . . . .

    Chapter 138, Laws of 1945, provided in pertinent part:
    Chapter 201, Laws of 1937, section 13a is created
    to read:
    (Chapter 201, Laws of 1937) Section 13a (1)
    LEGISLATIVE POLICY.   Employes have been attracted to
    and have remained in the public service in counties of
    more than 500,000 population despite the prevailing
    higher wages in other employments because of the
    deferred compensation for their services promised to
    them in the form of retirement annuities and death
    benefits in the retirement system to which they have
    been admitted as contributing members. The purpose of
    this act is to strengthen the public service in the
    most populous counties of the state by establishing
    the security of such retirement and death benefits.
    (2) CONTRACTS TO ASSURE BENEFITS.   The benefits

    beneficiaries,   and of   beneficiaries  of  deceased
    members in the retirement system created by chapter

    shall have a vested right to such annuities and other benefits
    and   they   shall   not   be   diminished   or   impaired   by    subsequent
    legislation or by any other means without his consent."                   
    Id. The legislature
    further provided that each MCERS member has a
    201, laws of 1937, as amended, shall be assured by
    benefit contracts as herein provided:
    (a) Every such member and beneficiary shall be
    deemed to have accepted the provisions of this act and
    shall thereby have a benefit contract in said
    retirement system of which he is such member or
    beneficiary as of the effective date of this act
    unless, within a period of 30 days thereafter, he
    files with the board administering the system a
    written notice electing that this act shall not apply
    to him.   The annuities and all other benefits in the
    amounts and upon the terms and conditions and in all
    other respects as provided in the law under which the
    system was established as such law is amended and in
    effect on the effective date of this act shall be
    obligations of such benefit contract on the part of
    the county and of the board administering the system
    and each member and beneficiary having such a benefit
    contract shall have a vested right to such annuities
    and other benefits and they shall not be diminished or
    impaired by subsequent legislation or by any other
    means without his consent.
    . . .
    (c) Every future entrant who shall become a
    member of this retirement system [MCERS] after the
    effective date of this act shall have a similar
    benefit contract and vested right in the annuities and
    all other benefits in the amounts and on the terms and
    conditions and in all other respects as provided in
    the law under which the retirement system was
    established as such law shall have been amended and be
    in effect at the date of commencement of his
    membership [in MCERS].

    amounts    and   on   the     terms    and      conditions       and     in    all    other
    respects    as   provided      in     the       law    under     which    [MCERS]       was
    established as such law shall have been amended and be in effect
    at the date of commencement of his membership [in MCERS]."                            
    Id. ¶6 In
      1957   the    legislature            provided   that     a    member    of
    MCERS has a "vested right . . . to all increases in benefits
    covered by amendments subsequent to the date his membership [in
    MCERS] is effective."         § 6, ch. 326, Laws of 1957.
    ¶7      In 1965 the legislature granted "home rule" authority
    to Milwaukee County over MCERS.                  § 1, ch. 405, Laws of 1965.8
    8
    Section 1 of ch. 405, Laws of 1965 provided in relevant
    part:
    Chapter 155,           laws    of      1937,     section      59.137    is
    created to read:
    (Chapter 155, laws of 1937) 59.137 PENSION STUDY
    COMMISSION.    (1) For the purpose of best protecting
    the   employes   subject  to  this   act  by   granting
    supervisory authority over each benefit fund created
    hereunder to the governmental unit most involved
    therewith, it is declared to be the legislative policy
    that the future operation of each such benefit fund is
    a matter of local affair and government and shall not
    be construed to be a matter of state-wide concern.
    Each county which is required to establish and
    maintain a benefit fund pursuant to this act is hereby
    empowered by county ordinance, to make any changes in
    such benefit fund which hereafter may be deemed
    necessary or desirable for the continued operation of
    such benefit fund, but no such change shall operate to
    diminish or impair the annuities, benefits or other
    rights of any person who is a member of such benefit
    fund prior to the effective date of any such change.
    7
    No.     2012AP2466
    This session law provided that "the future operation of each
    [county] benefit fund is a matter of local affair and government
    and   shall      not    be    construed      to      be   a   matter    of     state-wide
    concern."        
    Id. This law
    empowered Milwaukee County "to make any
    changes in [its employee] benefit fund which hereafter may be
    deemed necessary or desirable for the continued operation of
    [MCERS]."         
    Id. However, "no
          such   change   shall       operate   to
    diminish or impair the annuities, benefits or other rights of
    any person who is a member of [MCERS] prior to the effective
    date of any such change."              
    Id. ¶8 On
    or about December 17, 1981, Milwaukee County passed
    an ordinance that applied a 1.5% pension benefit multiplier to
    county service performed by an employee whose employment with
    the County began after January 1, 1982.                       M.C.G.O. § 201.24(5.1)
    (1981).9    Thus, under this ordinance, the pension payments for an
    employee whose employment with the County began after January 1,
    1982,     were    calculated      by    multiplying        1.5%    by   the    employee's
    final average salary, and the resulting number was multiplied by
    the employee's total years of service with Milwaukee County.
    
    Id. 9 This
    ordinance provided in relevant part: "A [MCERS]
    member . . . other than a deputy sheriff or elected official,
    whose continuous membership began after January 1, 1982, who
    meets the requirements for a normal pension shall receive an
    amount equal to one and one-half (1 1/2) percent of his final
    average salary multiplied by the number of his years of
    service . . . ."
    8
    No.       2012AP2466
    ¶9      On or about April 13, 1982, Stoker began employment
    with Milwaukee County and thereby became a member of MCERS.
    Stoker      was     a       Milwaukee        County     employee         and     MCERS       member
    continuously since then and still was both when this lawsuit was
    filed.
    ¶10     On       or     about        November     2,     2000,       Milwaukee         County
    increased the pension multiplier to 2% for county employees,
    effective     January          1,   2001.          M.C.G.O.     § 201.24(5.15)              (2000).
    This 2% multiplier applied to "all pension service credit earned
    on and after January 1, 2001."                         
    Id. This 2%
    multiplier also
    applied     retroactively             to     eight     years        of     service     prior      to
    January 1, 2001, for each year of service performed after that
    date.
    ¶11     In        approximately            May    2011,        the     Federation          and
    Milwaukee County negotiated the terms of a collective bargaining
    agreement for January 1, 2012, through December 1, 2012.                                      Under
    the   terms       of    the    collective          bargaining       agreement,         a    pension
    multiplier of 1.6% would apply to "all pension service credit
    earned on and after January 1, 2012."                         On or about May 23, 2011,
    the Federation ratified the collective bargaining agreement.                                      On
    or about June 23, 2011, Milwaukee County approved the collective
    bargaining        agreement.          On    or     about     July    28,     2011,      Milwaukee
    County      implemented          the        collective       bargaining          agreement        by
    adopting      an       ordinance,          which    provided        that     a   1.6%       pension
    multiplier would apply to "service . . . rendered on and after
    January 1, 2012."               M.C.G.O. § 201.24(5.1)(2)(f) (2011).                            This
    ordinance is the subject of this lawsuit.
    9
    No.    2012AP2466
    ¶12   By virtue of the ordinance adopted in 2000, the 2%
    multiplier applied to all of Stoker's county service through
    December     31,    2011.          The    ordinance       at    issue      changed     the
    multiplier     to    1.6%     only       with    respect       to   Stoker's      future,
    unearned service rendered on and after January 1, 2012.                             To be
    clear, the ordinance at issue did not affect the 2% multiplier
    that    applied     to   Stoker's        vested    retirement        benefits      earned
    through December 31, 2011.
    II.    PROCEDURAL POSTURE
    ¶13   On December 16, 2011, Stoker and the Federation filed
    suit in circuit court against Milwaukee County and the Pension
    Board. Stoker sought relief declaring that the 2011 ordinance
    that reduced the pension multiplier from 2% to 1.6% with respect
    to    post-2011     county    service       is    invalid.      Stoker     also    sought
    injunctive    relief     requiring        Milwaukee    County       and    the    Pension
    Board to apply the 2% multiplier to Stoker's county service
    performed on and after January 1, 2012, the effective date of
    the    ordinance.    Stoker        argued   that    the    2011     ordinance       was   a
    breach of contract.10 Stoker, Milwaukee County, and the Pension
    Board filed motions for summary judgment.
    ¶14   On July 11, 2012, the circuit court granted Stoker's
    motion for summary judgment.                The circuit court reasoned that,
    10
    Stoker also argued that the 2011 ordinance was an
    impairment of contract and an uncompensated taking of property
    in violation of Article I, Sections 12 and 13 of the Wisconsin
    Constitution. Stoker later abandoned these arguments, which are
    not before this court.
    10
    No.    2012AP2466
    under      ch.    138    of    the     Laws     of     1945,     Stoker     had       a    vested
    contractual right to retirement benefits since her employment
    with Milwaukee County began.                     According to the circuit court,
    this right includes the 2% multiplier.
    ¶15        Milwaukee County and the Pension Board appealed.                                 On
    November 14, 2013, the court of appeals affirmed.

    IV.    ANALYSIS
    ¶19    Stoker argues that the Milwaukee County ordinance that
    reduced the pension multiplier from 2% to 1.6% for post-2011
    service does not apply to her because the County is barred from
    making such prospective-only reductions to her vested retirement
    benefits without her personal consent.                 Stoker relies heavily on
    12
    No.     2012AP2466
    the    session    laws    from    1945,      1957,    and    1965     to    support        her
    argument.      In short, she argues that she is entitled to the most
    favorable      pension     formula       available      during       her     employment.
    Stoker    asserts    that    when      the    County    amended       the        formula    to
    reduce the multiplier from 2% to 1.6% for unearned benefits, it
    served to "diminish or impair" her vested benefits.
    ¶20    Milwaukee     County       argues      that    the     legislature           has
    endowed it with home rule authority to enact prospective changes
    in the Milwaukee retirement system.                   The County argues that the
    pension formula reduction and its prospective-only application
    did    not    "diminish     or    impair"         benefits       already    accrued        for
    pension service credits earned.                    The County contends that the
    change does not "diminish or impair" Stoker's benefits because
    any potential future benefit, due to future service, is not
    vested until earned.             The County asserts that under its home
    rule    authority,    it    has    the    authority         to    amend    its     unvested
    pension plans with prospective-only application.
    ¶21    Because Milwaukee County reduced the multiplier only
    prospectively, we first determine whether the County has the
    legal right to reduce employee benefits on a prospective-only
    basis.       We next determine whether Stoker has a vested right to
    have the 2% multiplier apply to her post-2011 service.                              Because
    we    conclude    that     Milwaukee      County       may       prospectively       reduce
    unvested employee benefits and that Stoker has no vested right
    to have the 2% multiplier apply to her post-2011 service, we do
    not    consider   whether        the   Federation      may       consent    on     Stoker's
    behalf to a prospective reduction of her vested benefits.
    13
    No.    2012AP2466
    A. Whether Milwaukee County May Prospectively
    Reduce an Employee Benefit
    ¶22    To   determine        whether        Milwaukee        County        may
    prospectively modify unvested benefits, we turn to the session
    laws   that    govern    MCERS.     Chapter    138      of   the    Laws   of   1945
    provides that every member of MCERS has a "vested right in the
    annuities and all other benefits in the amounts and on the terms
    and conditions . . . in effect at the date of commencement of
    his membership [in MCERS]."          Similarly, ch. 326 of the Laws of
    1957 provides each MCERS member with a "vested right . . . to
    all increases in benefits covered by amendments subsequent to
    the date his membership is effective."               However, ch. 405 of the
    Laws of 1965 gives to Milwaukee County home rule authority "to
    make any changes in [its employee] benefit fund which hereafter
    may be deemed necessary or desirable for the continued operation
    of [MCERS]."       Stoker notes that ch. 405 expressly limits this
    home   rule    authority    by    stating   that     "no     such   change      shall
    operate to diminish or impair the annuities, benefits or other
    rights of any person who is a member of [MCERS] prior to the
    effective date of any such change."
    ¶23    Stoker interprets ch. 405 of the Laws of 1965 to allow
    Milwaukee County to reduce benefits only with respect to persons
    who began employment with Milwaukee County after the reduction
    takes effect.       Stoker reaches this interpretation by invoking
    the canon of statutory construction known as the rule of the
    last antecedent, arguing that "prior to the effective date of
    any    such    change"   modifies    "who     is    a    member"     rather      than
    14
    No.    2012AP2466
    "annuities, benefits or other rights."                Stoker thus argues that
    ch. 405 forbids Milwaukee County from reducing a benefit of a
    person whose county employment began prior to the effective date
    of the reduction.       We disagree.
    ¶24    The    principle       of     interpreting      statutes       to    avoid
    unreasonable     or    absurd   results       is    more   compelling      in   this
    instance than the rule of the last antecedent.                  See Kalal, 
    271 Wis. 2d 633
    , ¶46; Chickasaw Nation v. United States, 
    534 U.S. 84
    , 94 (2001) (quoting Circuit City Stores, Inc. v. Adams, 
    532 U.S. 105
    , 115 (2001)) (holding that canons of construction "'are
    often   countered . . . by        some    maxim     pointing   in    a    different
    direction.'").        Stoker's interpretation of ch. 405 of the Laws
    of 1965 would prohibit Milwaukee County from reducing a current
    employee's expected, future benefits before they vest.                          That
    interpretation is unreasonable because a right that is unvested,
    by definition, can be taken away.                  See Black's Law Dictionary
    1520 (10th ed. 2014) (A "vested right" is a "right that so
    completely and definitely belongs to a person that it cannot be
    impaired or taken away without the person's consent."); Neiman
    v. Am. Nat. Prop. & Cas. Co., 
    2000 WI 83
    , ¶14, 
    236 Wis. 2d 411
    ,
    
    613 N.W.2d 160
    ("The concept of vested rights is 'conclusory——a
    right is vested when it has been so far perfected that it cannot
    be taken away by statute.'") (quoting Charles B. Hochman, The
    Supreme   Court       and   the        Constitutionality       of     Retroactive
    Legislation, 73 Harv. L. Rev. 692, 696 (1960)).                      We therefore
    conclude that ch. 405's limit on Milwaukee County's home rule
    15
    No.        2012AP2466
    authority allows Milwaukee County to reduce a benefit that has
    not vested prior to the effective date of the reduction.
    ¶25     Indeed, Stoker seems to recognize that ch. 405's grant
    of   home    rule   authority     allows         Milwaukee       County    to     reduce      a
    current employee's expected, future benefits before they vest.
    Specifically,       Stoker    argues        that     ch.        405    does     not     allow
    Milwaukee County to reduce the 2% multiplier with respect to her
    post-2011     service     because     her    "right        to    the    use     of    the    2%
    multiplier as to future as well as past service was already 'in
    existence'" when the multiplier was reduced.                             Thus, Stoker's
    logic    seems      to    acknowledge       that     ch.        405     would        allow   a
    prospective reduction of the 2% multiplier if she did not have a
    vested right to have the 2% multiplier apply to her post-2011
    service.
    ¶26     Because     Milwaukee      County      may        prospectively          reduce
    benefits before they vest, our analysis turns on whether Stoker
    has a vested right to the 2% multiplier for post-2011 service.
    B. Whether Stoker Has a Vested Right to Have the 2% Multiplier
    Apply to Her Post-2011 Service for Milwaukee County
    ¶27     Having determined that the home rule authority in ch.
    405 of the Laws of 1965 allows Milwaukee County to prospectively
    reduce      benefits     before   they      vest,    we     now       determine       whether
    Stoker has a vested right to have the 2% multiplier apply to her
    post-2011 service.
    ¶28     An employee benefit may be modified before it vests.

    2008 WI 129
    , ¶¶33-43, 
    315 Wis. 2d 35
    ,
    
    758 N.W.2d 766
    .          In Loth, prior to 2004, the City of Milwaukee
    16
    No.    2012AP2466
    offered      premium-free     health    insurance        to    its     employees        that
    reached age 60, were employed by the city for at least 15 years,
    and retired. 
    Id., ¶2. In
    2002 the city amended this retirement
    benefit      to     provide   shared-premium-cost             health      insurance       to
    anyone who reached age 60, was employed by the city for at least
    15 years, and retired after January 1, 2004.                      
    Id. Loth had
    15
    years of city service in 1999, and in 2005 he reached age 60 and
    retired.          
    Id. When Loth
    received shared-premium-cost health
    insurance after retiring, he sued the city, arguing that he was
    entitled      to    premium-free      health       insurance.          
    Id., ¶3. He
    reasoned that he reached 15 years of service when the premium-
    free health insurance retirement benefit was in effect, and that
    reaching 15 years of city service was the only requirement for
    becoming entitled to this benefit.                 
    Id. ¶29 We
       upheld    the    city's     modification         of    the    retiree
    health insurance benefit with respect to Loth.                        
    Id., ¶¶6-7. We
    determined that the city made a unilateral contract offer of
    premium-free        retiree   health    insurance        benefits,        and    that    the
    city modified the benefits before Loth became entitled to them
    by accepting the offer.             
    Id., ¶¶6, 14.
           We focused on the terms
    and conditions of the benefits to determine how they could be
    accepted by an employee and thus become an entitlement.                                 
    Id., ¶31. According
    to the terms and conditions of the city's health
    insurance benefits for retirees, the benefits were accepted and
    became       an    entitlement      when      an    employee         fulfilled         three
    requirements: being employed by the city for 15 years, reaching
    age 60, and retiring.            
    Id., ¶¶6, 16-29.
                Because Loth did not
    17
    No.     2012AP2466
    "perform the requested acts" of reaching age 60 and retiring
    while the premium-free health insurance benefit was in effect,
    
    id., ¶14, he
    had no contractual right to this benefit.                          
    Id., ¶6; see
    also 
    id., ¶39 (Loth
    had no right to premium-free health
    insurance upon retirement because "he had not fully performed
    the   services      entitling      him   to    such       benefits     when    the    City
    amended     [its]    policy . . . .").          We     distinguished          cases   that
    rejected employers' attempts to reduce their employees' benefits
    after they vested.              
    Id., ¶¶32-46. Thus,
    Loth stands for the
    principle that an employer may modify a benefit that has not
    vested because its terms and conditions for entitlement have not
    been satisfied.
    ¶30    To determine whether Milwaukee County reduced a vested
    benefit of Stoker, we focus on the terms and conditions of the
    multiplier.         See    
    id., ¶31; see
       also      ch.   138,    Laws    of    1945
    (stating that MCERS members have a vested right to benefits on
    the "terms and conditions" of the benefits).                           The terms and
    conditions of the 2% multiplier are located in Milwaukee County
    ordinances     and        the   collective     bargaining        agreement.            The
    ordinance that created the 2% multiplier stated that the 2%
    multiplier applied to "all pension service credit earned on and
    after January 1, 2001."             M.C.G.O. § 201.24(5.15)(1)(a) (2000).12
    Pension     credit    service       is   earned      by    rendering     service       for
    Milwaukee County.          M.C.G.O. App. B. § 301 (1980).               The ordinance
    12
    This ordinance created a 2% multiplier by adding 0.5% to
    the existing 1.5% multiplier. See supra note 5.
    18
    No.    2012AP2466
    at    issue    provided        that     the        1.6%   multiplier           applied    to
    "service . . . rendered on and after January 1, 2012."                            M.C.G.O.
    § 201.24(5.1)(2)(f) (2011).               Likewise, the collective bargaining
    agreement adopted in 2011 provided that a 1.6% multiplier would
    apply    to    "all    pension     service         credit    earned       on     and    after
    January 1, 2012."           The plain language of these ordinances and
    the collective bargaining agreement shows that the multiplier
    accrues      over    time   as    county       service      is    rendered,       and    the
    multiplier     is     directly     tied      to    that     service.           Because    the
    multiplier accrues as service is rendered, the home rule power
    in ch. 405 of the Laws of 1965 allows Milwaukee County to reduce
    the multiplier with respect to Stoker's service rendered after
    the effective date of the reduction.
    ¶31    Other case law also supports our conclusions that the
    multiplier accrues over time as service is rendered and that,
    therefore,      Milwaukee        County      may    reduce       the    multiplier       with
    respect to service rendered after the reduction takes effect.
    In Loth we discussed the court of appeals' decision in Champine
    v.    Milwaukee      County,     2005     WI   App    75,    
    280 Wis. 2d 603

    .         Loth, 
    315 Wis. 2d 35
    , ¶¶44-46.                     We noted that the
    court of appeals in Champine held that a "payout for accrued
    sick leave represents a benefit that is 'earned as the work is
    performed.'         An employee accrues sick allowance (and may earn
    the right to receive             payout for the accrued sick allowance)
    gradually as the employee performs his or her work."                           
    Id., ¶46. ¶32
       In Champine, prior to 2000, Milwaukee County allowed
    its     non-union      employees        to     receive       the        cash     value     of
    19
    No.    2012AP2466
    approximately       400     hours        of    their      unused     sick        leave      upon
    retirement.         Champine,        
    280 Wis. 2d 603
    ,        ¶¶2-3.             In    2000
    Milwaukee County adopted an ordinance that allowed its non-union
    employees to receive the cash value of all of their unused sick
    leave upon retirement.             
    Id. This ordinance
    did not have a start
    date or end date.           
    Id., ¶2. In
    February 2002 Milwaukee County
    adopted     an   ordinance    that        limited      non-union     employees'             sick-
    leave payout at retirement to approximately 400 hours of unused
    sick leave, effectively reinstating the limit in place prior to
    2000.     
    Id., ¶6. This
    February 2002 ordinance took effect on
    March 15, 2002.       
    Id. ¶33 The
      court    of    appeals         held   that     the    2002        ordinance
    lawfully limited the sick-leave payout benefit with respect to
    sick leave that accrued after the limit took effect.                                 
    Id., ¶¶15- 17.
          Specifically,       the        court      held    that         the     ordinance's
    prospective reduction of the sick-leave payout benefit did not
    breach    a   contract      with    the       non-union     employees.               
    Id., ¶14. However,
    the court held that non-union employees who retired
    after the effective date of the 2002 ordinance were entitled to
    receive a retirement payout of all of the sick leave that they
    accrued prior to the effective date of the 2002 ordinance.                                  
    Id., ¶¶15-17. The
    court reasoned that the sick-leave payout benefit
    is "a form of deferred compensation that is earned as the work
    20
    No.   2012AP2466
    is performed.        The benefit can be changed, but only as it is
    related to work not yet performed."

       In   Pasko v. Milwaukee County, 
    2013 WI App 91
    , 
    349 Wis. 2d 444
    , 
    836 N.W.2d 461
    , two Milwaukee County retirees sued
    the County for paying them the cash value of approximately 400
    hours of unused sick leave upon retirement.               The two plaintiffs
    had been union members while Milwaukee County employees, and
    their union contracts provided that upon retirement they would
    receive a cash payout of all of their unused sick leave.                   Pasko,
    
    349 Wis. 2d 444
    ,      ¶6.      Before    retiring,   the    plaintiffs    were
    promoted to non-union managerial positions, thus subjecting them
    to    the    Milwaukee   County    ordinance    adopted   in    February    2002,
    which limited the sick-leave payout upon retirement for non-
    13
    Stoker argues that Champine is distinguishable because
    the court of appeals stated that "in the absence of a collective
    bargaining agreement or employment contract, [Milwaukee County]
    should not be bound to continue providing a benefit it now
    regrets offering." Champine v. Milwaukee Cnty., 
    2005 WI App 75
    ,
    ¶19, 
    280 Wis. 2d 603
    , 
    696 N.W.2d 245
    .     Stoker interprets this
    language to mean that Champine involved neither a collective
    bargaining agreement nor a contract, unlike the present case.
    To the contrary, the court of appeals explained that the 2000
    ordinance, which provided a right to a payout of all unused sick
    leave upon retirement, was a contract while it was in effect.
    
    Id., ¶14. This
    quoted language simply meant that the 2000
    ordinance did not provide a vested right to the sick-leave
    payout with respect to future service.      In any event, in a
    nearly identical case that involved union contracts with
    Milwaukee County, the court of appeals reached the same
    conclusion as it did in Champine. See Pasko v. Milwaukee Cnty.,
    
    2013 WI App 91
    , ¶¶9-14, 
    349 Wis. 2d 444
    , 
    836 N.W.2d 461
    . Thus,
    the fact that Champine did not involve union contracts or
    collective   bargaining   agreements   is    not  a    meaningful
    distinction.

    No.     2012AP2466
    union employees to approximately 400 hours of unused sick leave.
    
    Id., ¶¶3-6. This
    ordinance was at issue in Champine.                        
    Id., ¶5. Because
    the plaintiffs retired as non-union employees, Milwaukee
    County argued that, under the 2002 ordinance, they were entitled
    to   a    payout     of    only    approximately      400     hours    of    unused       sick
    leave.      
    Id., ¶¶6, 9.
    ¶35   The court of appeals held that the plaintiffs were
    entitled to a payout upon retirement of all of the unused sick
    leave     that      they    accrued    while      they     were     covered       by    union
    contracts with Milwaukee County.                     
    Id., ¶13. Under
    the union
    contracts,       the      sick-leave    hours       that    the     plaintiffs         accrued
    while they were union members "vested as they were earned."
    
    Id., ¶¶9-13. Thus,
    the "vesting trigger" of sick leave was the
    "day-by-day accrual" of sick leave.                   
    Id., ¶12. The
    court noted
    that     Milwaukee        County    could    have    used,    but     did     not      use,    a
    different      vesting       trigger    in    its     union       contracts       so    as    to
    preserve its ability to retroactively reduce the amount it was
    required to pay retirees for sick leave already accrued.                               
    Id. ¶36 In
       Valeo    v.     J. I.   Case     Co.,     
    18 Wis. 2d 578
    ,           
    119 N.W.2d 384
    (1963), a collective bargaining agreement provided
    that employees were eligible for a certain amount of vacation
    pay annually and that the right to vacation pay began accruing
    each year on June 1.                
    Valeo, 18 Wis. 2d at 579
    .                The employer
    terminated the collective bargaining agreement on February 29,
    1960, three months before June 1.                      
    Id. A strike
    ensued and
    lasted until a new collective bargaining agreement was signed on
    September 19, 1960.                
    Id. at 579-80.
             The employer denied its
    22
    No.    2012AP2466
    employees      any       vacation      pay   for      the    period     of     June    1,     1959,
    through February 29, 1960, arguing that the right to vacation
    pay did not vest until June 1 and that the collective bargaining
    agreement         was     terminated      before       June      1.     
    Id. at 580.
          An
    employee sued the employer, arguing that he was entitled to
    vacation pay that accrued during the nine months from June 1,
    1959, through February 29, 1960.                       
    Id. at 580,
    583.               This court
    held that the employee had a vested right to the vacation pay
    that   "accrued           as   services      were      performed"        for    the     employer
    during these nine months.                 
    Id. at 585.
               The court reasoned that
    "the     nature         of     vacation      pay      [is]       compensation         for      work
    performed,"         and      the   collective         bargaining        agreement       did    not
    provide that the right to vacation pay vested based on something
    besides service rendered.               
    Id. ¶37 Champine,
    Pasko, and Valeo show that certain employee
    benefits, by their nature, accrue as service is rendered unless
    a contract or law states otherwise. In the present case, "the
    nature"      of     the      pension   multiplier           is   "compensation         for     work
    performed."             See 
    id. As we
    already explained, the relevant
    Milwaukee          County      ordinances        and     the      collective          bargaining
    agreement expressly state that the multiplier accrues as service
    is rendered.            See M.C.G.O. §§ 201.24(5.15) (2000), App. B. 301
    (1980), 201.24(5.1)(2)(f) (2011).                      If Milwaukee County wanted to
    make   the        2%    multiplier      vest       immediately          when    enacted        with
    respect to all future service, it could have used a "vesting
    trigger" besides "day-by-day accrual," but "[i]t did not."                                      See
    Pasko,       
    349 Wis. 2d 444
    ,       ¶12.         Thus,      the    language        of     the
    23
    No.     2012AP2466
    ordinances and collective bargaining agreement and the nature of
    the multiplier show that the multiplier, like vacation pay and
    sick leave, accrues over time as service is rendered.
    ¶38    Because       the    multiplier             is   "a    form     of      deferred
    compensation that is earned as the work is performed," it "can
    be    changed,   but       only    as    it        is    related    to     work     not   yet
    performed."          See   Champine,          
    280 Wis. 2d 603
    ,       ¶16.     See   also

    627 N.W.2d 807
          (holding      that      statute
    governing      Wisconsin         Retirement         System,        which     stated       that
    benefits accrued as service is rendered, allows reduction of
    benefits      with     respect          to     service        performed           after   the
    reduction).14

    The statute in Lightbourn provided in relevant part:
    Rights exercised and benefits accrued to an
    employee under this chapter for service rendered shall
    be due as a contractual right and shall not be
    abrogated by any subsequent legislative act.       The
    right of the state to amend or repeal, by enactment of
    statutory changes, all or any part of this chapter at
    any time, however, is reserved by the state and there
    shall be no right to further accrual of benefits nor
    to future exercise of rights for service rendered
    after the effective date of any amendment or repeal
    deleting the statutory authorization for the benefits
    or rights.

    ¶39    Loth, Champine, Pasko, and Valeo show that Stoker's
    reliance on ch. 138 of the Laws of 1945, ch. 326 of the Laws of
    1957, and ch. 405 of the Laws of 1965 is misplaced.                     These
    chapters state that MCERS members shall have a benefits contract
    that protects their vested rights, but these chapters do not
    explain whether the 2% multiplier is a vested right with respect
    to future service.       Indeed, these chapters do not mention this
    multiplier at all.15       As we explained, the relevant Milwaukee
    County   ordinances,     the   collective    bargaining      agreement,    and
    Loth, Champine, Pasko, and Valeo show that Stoker did not have a
    vested right to have the 2% multiplier apply to her post-2011
    service.
    ¶40    We note that our conclusion that Milwaukee County may
    prospectively   modify    benefits   before    they   vest    is    consistent
    with the anti-cutback rule of the Employee Retirement Income
    Security Act ("ERISA") of 1974.16           The anti-cutback rule allows
    Wis. Stat. § 40.19(1) (1997-98). Stoker argues that Lightbourn
    is not helpful in the present case because, unlike Wis. Stat.
    § 40.19(1), the session laws governing MCERS do not state that
    benefits accrue as service is rendered or allow prospective
    reductions of benefits. However, the relevant Milwaukee County
    ordinances and collective bargaining agreement state that the
    pension multiplier accrues as service is rendered, and ch. 405
    of the Laws of 1965 allows prospective reduction of unvested
    benefits.    Thus, we find helpful the Lightbourn court's
    conclusion that a benefit that accrues as service is rendered
    may be prospectively reduced.
    15
    Section 1 of ch. 326, Laws of 1957 mentions a multiplier,
    but Stoker does not argue that this multiplier is relevant in
    the present case.

    Cent. Laborers' Pension Fund v. Heinz, 
    541 U.S. 739
    , 747 (2004).
    The anti-cutback rule prohibits employers subject to ERISA from
    adding new conditions to benefits that have accrued for service
    rendered.     
    Id. Stoker argues
          that   Milwaukee         County    may     go
    beyond the protections under the anti-cutback rule by providing
    benefits that vest before service is rendered.                          However, as we
    have   explained,        the      relevant    Milwaukee     County      ordinances           and
    collective bargaining agreement show that the multiplier is a
    benefit that accrues for service rendered.
    ¶41   Similarly,           Stoker's    reliance      on    Welter       v.    City     of
    Milwaukee, 
    214 Wis. 2d 485
    , 
    571 N.W.2d 459
    (Ct. App. 1997), and
    Rehrauer v. City of Milwaukee, 
    2001 WI App 151
    , 
    246 Wis. 2d 863
    ,
    
    631 N.W.2d 644
    ,       is    also      misplaced.       In     Welter      the     City     of
    Milwaukee    provided         a   duty    disability      retirement         allowance        to
    police officers who became disabled due to injuries suffered in
    the course of their employment.                    
    Welter, 214 Wis. 2d at 487-88
    .
    At a certain age, known as the conversion age, an officer who
    was    receiving     a    duty      disability       retirement        allowance           began
    receiving a less-generous service retirement allowance instead.
    
    Id. at 488.
           The City of Milwaukee lowered the conversion age
    while the plaintiffs were employed as police officers.                               
    Id. The plaintiffs
       became          disabled       and    received      a    duty        disability
    retirement allowance that was converted to a service retirement
    allowance when they reached this lower conversion age.                               
    Id. The plaintiffs
    sued the city, arguing that they had a vested right
    26
    No.    2012AP2466
    to the higher conversion age that was in effect when they began
    employment     with    the    City   of    Milwaukee.       
    Id. The court
      of
    appeals agreed with the plaintiffs.                
    Id. The court
    of appeals
    reasoned that an officer's right to a disability pension vests
    when the officer begins employment with the City of Milwaukee,
    rather than when the officer becomes disabled.                     
    Id. at 494-95.
    The   court    held    that    two   session     laws    governing    the   City    of
    Milwaukee's retirement system dictated this result.                   
    Id. ¶42 Welter
      is     inapposite    in   the     present   case.      Welter
    involved a right that vested when a person began employment.                        In
    the present case, we already determined that Stoker accrues a
    right to the pension multiplier as she renders county service.
    Further, the multiplier in effect when Stoker began employment
    with Milwaukee County was 1.5%, and the multiplier has not been
    reduced below that level with respect to any of Stoker's past or
    future service.17       Although the court of appeals in Welter relied
    solely on two session laws to conclude that a disability pension
    vested when employment began, we think the better approach in
    the present case is to interpret the relevant ordinances to
    determine the extent to which the multiplier was a "vested"
    right within the meaning of the session laws governing MCERS.

    This fact also provides a basis for distinguishing ch.

    because this chapter applies only to benefits in existence when

    City of Milwaukee provided limited-term duty disability benefits
    to    its     firefighters        who     became       disabled        due     to    an    injury
    suffered during the course of employment.

          After September 30, 1977, the City of Milwaukee again

    ¶44    The    court      of   appeals       agreed    with    the   firefighters.
    
    Id. The court
    concluded that "the firefighters gained vested
    rights in the highest level of duty disability benefits that
    came   to    be     contractually          established      during       their    years   of
    active duty."            
    Id., ¶20. The
    court reasoned that, "[u]nder
    § 36-13-2-c of the Milwaukee City Charter, [the plaintiffs] have
    a 'vested right in the . . . benefits in the amounts and on the
    terms and conditions and in all other respects as provided in
    the law . . . in effect at the date of commencement of his [or
    her]    membership        and     as    subsequently         amended.'"           
    Id., ¶16 (emphasis
    added by court of appeals).
    ¶45    Rehrauer       is      inapposite      in     the     present      case.    In
    Rehrauer      the    court      of     appeals     relied    on     an   ordinance       that
    expressly provided a vested right to an increase in benefits,
    and it also relied on the holding in Welter that disability
    benefits vest immediately rather than when an employee becomes
    disabled.         
    Id., ¶¶13-14, 16.
         In    contrast,      the     ordinances
    relevant in the present case do not state that MCERS members
    have a vested right to have an increased multiplier apply in
    perpetuity.         To the contrary, these ordinances provide that the
    multiplier accrues over time as service is rendered.                             It is true
    that the ordinance relied upon in Rehrauer is similar to ch. 326
    of the Laws of 1957, which provides each MCERS member with a
    "vested      right . . . to          all    increases       in    benefits     covered     by
    amendments subsequent to the date his membership is effective."
    However, as we already discussed, ch. 326 does not explain the
    precise nature of the "vested right" it mentions.                              Because the
    29
    No.     2012AP2466
    multiplier vests over time as service is rendered, the "vested
    right" to which ch. 326 refers does not include a vested right
    to have the 2% multiplier apply in perpetuity.                          Rather, the
    "vested right" to which ch. 326 refers includes the right to
    have the 2% multiplier apply to all service that is rendered
    while the 2% multiplier is in effect.
    ¶46    Accordingly, we are not persuaded by Stoker's argument
    that Welter and Rehrauer apply in the present case because they
    involved session laws similar to the session laws that govern
    MCERS.      Disability benefits, unlike the pension multiplier, are
    a promise by an employer that is not conditioned on subsequent
    action by an employee, such as rendering service.                          Instead,
    disability benefits are a promise to receive coverage for an
    unforeseen event that happens at some point in the future.                        As
    we    explained,    we   rely     on     the     relevant     Milwaukee      County
    ordinances and the collective bargaining agreement to determine
    the extent to which the 2% multiplier is a vested right within
    the meaning of the session laws.               In light of these ordinances
    and the collective bargaining agreement, we conclude that Stoker
    does not have a vested right to have the 2% multiplier apply to
    her    post-2011    service,      which       she    rendered     after     the   2%
    multiplier was reduced to 1.6%.               Because Stoker did not have a
    vested right to have the 2% multiplier apply to her post-2011
    service,     Milwaukee   County    was    free      to   reduce   the    multiplier
    below 2% for her post-2011 service.                 See Loth,

    V.       CONCLUSION
    30
    No.     2012AP2466
    ¶47    We conclude that Milwaukee County did not breach the
    contract with Stoker when it amended the pension multiplier from
    2% to 1.6%.          The amendment did not breach Stoker's contractual
    right to retirement system benefits earned and vested because it
    had prospective-only application to future service credits not
    yet earned, specifically, on and after January 1, 2012.                              We
    conclude      that    the    legislature      preserved   Stoker's      rights      and
    benefits already accrued but also gave Milwaukee County home
    rule authority with the flexibility to enact such prospective-
    only changes.          We conclude that Stoker does not have a vested
    right to have the 2% multiplier apply to her then-unearned post-
    2011 service.         In other words, Milwaukee County could so amend
    the formula and apply it prospectively because that prospective
    application does not "diminish or impair" benefits accrued from
    service      credits    already     earned.         Because   we   conclude      that
    Milwaukee County did have the ability to make these prospective-
    only   reductions       of   the    multiplier      without   Stoker's      personal
    consent, we need not address whether the Federation lawfully
    consented, on Stoker's behalf, to the reduction.
    By    the   Court.—The      decision    of   the   court    of     appeals   is
    reversed and remanded.

    ¶48   ANN WALSH BRADLEY, J.              (dissenting).     Rather          than
    addressing the session laws which provide a clear answer to our
    inquiry and dictate protection of the employees' benefits, the
    majority shifts the focus of its analysis to language in the
    Milwaukee County General Ordinance.                  It is only by repeatedly
    ignoring the language of the governing session laws that the
    majority is able to conclude that the County may reduce the
    pension multiplier, thereby dealing a blow to the rights of the
    employees.
    ¶49   I   conclude       instead,    as    did   a    unanimous    court    of
    appeals, that the session laws mean what they say: employees
    have    a    vested     right     to    their     benefits    when     they   accept
    employment with the County and the County is not permitted to
    diminish or impair those benefits.                   As such, the County was
    without authority to pass an ordinance reducing Stoker's pension
    multiplier.        Accordingly, I respectfully dissent.
    I
    ¶50   The      Milwaukee        County    Employee     Retirement      System
    [MCERS] was created by the legislature in chapter 138 of the
    Laws of 1945.          That session law provided that employees shall
    have a benefit contract and vested rights to their benefits at
    the time each employee commences membership:
    Every future entrant who shall become a member of
    [MCERS] after the effective date of this act shall
    have a similar benefit contract and vested right in
    the annuities and all other benefits in the amounts
    and on the terms and conditions and in all other
    respects as provided in the law under which the
    retirement system was established as such law shall
    have been amended and be in effect at the date of
    commencement of his membership.

    Laws of 1945, Ch. 138 (emphasis added).                    The legislature did not
    refer       to    an   employee     earning        or   accruing    benefits     through
    services rendered.              Rather, the legislature provided that rights
    to   benefits          "vested"    at    the   "date      of   commencement      of   [an
    employee's] membership."1               It is hard to imagine how much clearer
    the legislature could have been.
    ¶51       Not     surprisingly,       Wisconsin     courts    have    previously
    concluded that language similar to that used in chapter 138 of
    the Laws of 1945 created a vested right to benefits at the time
    of hire.          In Welter v. City of Milwaukee, 
    214 Wis. 2d 485
    , 
    571 N.W.2d 459
    (Ct. App. 1997), the court considered substantially
    similar laws relating to police officers' retirement benefits.
    The session law at issue provided that:
    Every such member . . . shall thereby have a benefit
    contract in said retirement system of which he is such
    member or beneficiary as of the effective date of this
    act . . . . [E]ach member and beneficiary having such
    a [retirement system] benefit contract shall have a
    vested right to such annuities and other benefits and
    they shall not be diminished or impaired by subsequent
    legislation or by any other means without [the
    officer's] consent. . . . Every future entrant who
    shall become a member of this retirement system after
    the effective date of this act shall have a similar
    benefit contract and vested right in the annuities and
    all other benefits . . . .
    Laws       of    1947,    ch.    441,    §   30(2).        After    considering       this
    language, the court determined that the retirement benefits at
    issue vested at the time officers became employees.

    Welter,

    officer becomes a member of the retirement system are vested as
    to that officer unless the officer agrees to a change."                                        
    Id. The court
    rejected the city's argument that the rights vested at
    some later date, stating that "[t]his argument, however, ignores
    the legislative command that the critical date is not that of
    the duty-related disability but the date the officer becomes a
    member of the retirement system——the date he or she was first
    employed by the City as a police officer."

    , 
    631 N.W.2d 644

    that the officers' benefits vested at the date of hire).
    ¶53      The majority attempts to avoid the plain language of
    the session laws and the cases interpreting similar language by
    shifting    its   focus       to     the     language     of     the       Milwaukee      County
    General Ordinance.         Majority op., ¶30.                 It asserts that this is
    the proper approach because the session laws do not "explain
    whether the 2% multiplier is a vested right with respect to
    future     service"      and       thus,       the     majority          implies       that   the
    Ordinance     does.        
    Id., ¶39. Pointing
           to     the    Ordinance's
    statement    that      0.5%     of      the    multiplier        applies          to    "service
    rendered,"       the     majority          concludes          that        this    means       "the
    3
    No.     2012AP2466.awb
    multiplier accrues over time."                     
    Id., ¶30.2 It
    then states that
    Welter is inapposite because it relied on the language of the
    session laws and not an ordinance.                   
    Id., ¶42. ¶54
       Contrary to the majority's implications, the Ordinance
    does not directly address whether the multiplier creates vested
    rights with respect to future service.                      The majority's strained
    reasoning on this point conflicts with the common definition of
    the   word    "accrue."          The     word       "accrue"    generally         means    "to
    accumulate over time."             The American Heritage Dictionary of the
    English      Language      12    (3d     ed.       1992);   see    also        Black's     Law
    Dictionary        21    (7th     ed.     1999)       (defining         accrue     as     "[t]o
    accumulate periodically").
    ¶55    Nothing in the Ordinance indicates that the multiplier
    grows     over    time.         Under    the       Ordinance,     an    employee        "shall
    receive an amount equal to one and one-half (1½) percent of his
    final average salary multiplied by the number of his years of
    service rendered."         MCGO § 201.24(5.1)(1).
    ¶56    The       Ordinance       further       provides     that        "all     pension
    service credit earned on and after January 1, 2001, shall be
    credited in an amount equal to an additional one-half (0.5)
    percent      of    the     member's        final        average        salary."           MCGO
    § 201.24(5.15).          As indicated by the language of the Ordinance,
    the multiplier does not grow or accumulate in proportion to the
    2
    It is unclear why the majority focuses on the language in
    the Ordinance creating the additional 0.5% multiplier and not
    the   language   regarding  the   base  1.5%   multiplier,  MCGO
    § 201.24(5.1)(1). The two provisions have different language.

    years of service rendered.            It is the number of pension service
    credits   that   increases         over    time,       not   the   multiplier.           The
    multiplier itself does not "accrue."
    ¶57     The majority's refusal to acknowledge the words of the
    governing session laws is evident in its reliance on Champine,
    Pasko, and Valeo to support its conclusion that the multiplier
    accrues as service is rendered.                 I recognize that each of those
    cases determined that under the governing law or contract being
    interpreted,     the     benefit      at    issue        vested     as        service    was
    rendered.     However, each of those cases also acknowledged that
    legislation    or   a   contract      could          include   a   different         vesting
    trigger, such as the commencement of employment.                              See Champine
    v. Milwaukee County, 
    2005 WI App 75
    , ¶19,

    , 584, 
    119 N.W.2d 384
    (1963).
    ¶58     In this case, clear language in a governing session
    law creates a vesting trigger different from the trigger found
    in those cases.         Chapter 138 of the Laws of 1945 states that
    employees   "shall      have   a    similar          benefit   contract        and    vested
    right in the annuities and all other benefits in the amounts and
    on the terms and conditions . . . at the date of commencement of
    his membership."        In other words, upon acceptance of employment,
    employees   gain    a   vested      right       to    benefits     on    the    terms   and
    5
    No.   2012AP2466.awb
    conditions   of   the    contract.3        Because   one    of    the    terms   and
    conditions   of    the    pension     benefit    was       that    it    would    be
    calculated using a 2% multiplier, there is a vested right to
    that multiplier.
    ¶59   The majority further attempts to distance this case
    from the governing session laws by asserting that chapter 138 of
    the Laws of 1945 does not apply because that chapter applies
    only to benefits in existence when a person's county employment
    began and that the multiplier when Stoker began employment was
    1.5%, lower than the 1.6% at issue here.                    Majority op., ¶42
    n.17.   Again, the majority's narrow focus has led it astray.
    ¶60   Although chapter 138 of the Laws of 1945 could have
    initially been read as the majority posits, a 1957 amendment to
    that chapter clarifies that an employee has vested rights to
    increases in benefits, not just the benefits available at the
    start of employment.        Specifically, Chapter 326 of the Laws of
    1957 amended the language to read:

    , the majority alludes to the argument that
    the session law was a unilateral contract offer that the county
    could modify until an employee became entitled to the benefits
    by accepting the offer.       Majority op., ¶¶29, 46.      It is
    understandable that the majority does not attempt to directly
    embrace the unilateral contract argument.    Neither the session
    law nor the Ordinance creates eligibility requirements that
    employees need to meet before being entitled to the multiplier.
    As illustrated above, to the extent the session law can be
    viewed as a unilateral contract offer, the only action an
    employee need take to accept the offer, and thereby create a
    binding contract, is to accept employment. Similarly, under the
    Ordinance, an employee is entitled to the multiplier regardless
    of how many years of service the employee has rendered.

    [E]ach member and beneficiary having such a benefit

    stated by the act at the time his membership is

    Ch. 326, Laws 1957, § 6 (emphasis added).
    ¶61     Nearly identical language was interpreted in Rehrauer,
    
    246 Wis. 2d 863
    .            In that case the ordinance at issue provided
    that firefighters have a "vested right in the . . . benefits in
    the amounts and on the terms and conditions and in all other
    respects as provided in the law . . . in effect at the date of
    commencement       of    his     membership         and    as   subsequently         amended."
    
    Id., ¶16 (quoting
    Milwaukee City Charter § 36-13-2-c).                                      Based
    on the language of the ordinance and the governing statutes, the
    principles    set        forth    in    Welter,          and    the   importance          of   the
    attraction        and     retention       of        public      employees,          the     court
    concluded that "firefighters gained vested rights in the highest
    level of duty disability benefits that came to be contractually
    established       during       their    years       of    active      duty."        
    Id., ¶20. Given
    that the language in this case is nearly identical to that
    at   issue    in        Rehrauer,       there       is     little      justification           for
    interpreting it differently.
    II
    ¶62     In    contrast        to    the        majority's        interpretation,            I
    conclude that the language of the session law governs: employees
    "shall have a vested right to all benefits stated by the act at
    the time his membership is effective and to all increases in
    benefits     covered       by    amendments          subsequent        to     the    date      his
    7
    No.   2012AP2466.awb
    membership is effective."               Ch. 326, Laws of 1957, § 6.                     This
    language      is    unambiguous         and       is     not    open    to     alternative
    interpretations.           See Madison Teachers, Inc. v. Walker, 
    2014 WI 99
    ,   ¶145,    __     Wis. 2d     ___,    
    851 N.W.2d 337
       (concluding      that
    similar provisions in Milwaukee's Charter "unmistakably evince
    the clear intention of the Common Council to create a 'vested
    and contractual right to the [pension] benefits in the amount
    and on the terms and conditions' as provided in [the Charter]").
    ¶63     Here,    upon     accepting         employment     with    the    County    in
    1982, Stoker entered into a contract which provided her with a
    vested      right     to    a    1.5%     pension         multiplier.           See     MCGO
    § 201.24(5.1) (1981).             During her employment, that multiplier
    was increased to 2%.            See MCGO § 201.24(5.15)(1) (enacted 2000).
    Under chapter 326 of the Laws of 1957, Stoker had a vested right
    to the increase as well.
    ¶64     Once her rights to the multiplier vested, the County
    was unable to reduce it.            The legislature's restrictions on the
    County's home rule authority with respect to altering employee
    benefits are clear.             It instructed that "no such change shall
    operate to diminish or impair the annuities, benefits or other
    rights of any person who is a member of [MCERS] prior to the
    effective date of any such change."                        Ch. 405, Laws 1965.            An
    ordinance     that     conflicts     with         the    authority      granted    by    the
    session laws is void.              See State ex rel. Ziervogel v. Wash.
    Cnty. Bd. of Adjustment, 
    2004 WI 23
    , ¶38, 
    269 Wis. 2d 549
    , 
    676 N.W.2d 401
    .        Here, the County’s amendment to the Ordinance would
    operate to reduce Stoker's pension multiplier to 1.6%, thereby
    8
    No.      2012AP2466.awb
    conflicting with the Legislature’s mandate that employee rights
    and benefits not be diminished.                     Accordingly, the amendment to
    the Ordinance is void.
    ¶65       In sum, the majority's attempt to avoid the language
    of   the     governing       session      laws      and    shift    the     focus     to   the
    language in the Ordinance is unpersuasive.                         It turns a blind eye
    to the clear language of the session laws which must trump the
    amendment to the County Ordinance.
    ¶66       Although the County offered employment to individuals
    with the promise that a certain pension benefit formula would
    accompany such employment,                the majority erroneously concludes
    that       the    County    has    unfettered        discretion       to       prospectively
    reduce it.         As a result, an employee who accepted the offer has
    no   contractual          rights     to   enforce      that      formula.         Because    I
    conclude         that    employees    have      a   vested    right       to    the   formula
    containing         the    multiplier      and       that   the     County       was   without
    authority to pass an ordinance reducing that multiplier, I would
    affirm the unanimous court of appeals' decision.4
    4
    The same day the court heard argument on this case, we
    also heard argument on another case involving when Milwaukee
    County employees' benefits become vested. The decision in that
    case is still pending. Efforts should be made to make the two
    opinions consistent. The core function of courts is, of course,
    clear, consistent, and reliable application of the law.
    Because   of  the   court's   new   procedure   for  opinion
    preparation and mandate, I cannot comment on the other decision
    at this time given that I want this dissent to be mandated at
    the same time as the majority opinion.     See State v. Gonzalez,
    
    2014 WI 124

    C.J., concurring) (setting forth the new procedure).
