Opinion
RYLAARSDAM, J.
Proposition 13 amended the California Constitution by prohibiting the imposition of ad valorem property taxes in excess of 1 percent of the cash value of property. It contains an exception allowing excess taxes or special assessments “to pay the interest and redemption charges on any ... [1] (1) [indebtedness approved by the voters prior to July 1, 1978.” (Cal. Const., art. XIII A, § 1, subd. (b)(1).) The issue in this case is whether passage of a new city charter by the voters of real party in interest City of Huntington Beach (City) in July 1978 constitutes prior voter approval of excess taxation for retirement benefits added after 1978. That charter (1) mandates City’s participation in “a retirement system”; (2) gives the city council discretion to “establish such reasonable compensation and fringe benefits as are appropriate [for City employees] by ordinance or resolution”; and (3) expressly provides for an excess tax “sufficient to meet all obligations of the City for the retirement system in which the City participates.” We agree with the trial court that excess taxation for the added retirement benefits violates Proposition 13 and affirm the judgment.
FACTS
The parties stipulated to the facts. The voters of the City approved a charter in 1966. Section 1100 of that charter, entitled “RETIREMENT,” [1378]*1378provides: “Authority and power are hereby vested in the City, its City Council and its several officers, agents, and employees to do and perform any act, and to exercise any authority granted, permitted, or required under the provisions of the State Employees’ Retirement Act, as it now exists or hereafter may be amended, to enable the City to continue as a contracting City under the State Employees’ Retirement System. The City Council may terminate any contract with ... the State Employees’ Retirement System only under authority granted by ordinance adopted by a majority vote of the electors of the City ...”
Section 1207 of the former charter stated: “(a) The City Council shall not levy a property tax for municipal purposes in excess of One Dollar annually on each One Hundred Dollars of the assessed value of taxable property in the City, except as otherwise provided in this Section .... [][] (b) There shall be levied and collected at the same time and in the same manner as other property taxes for municipal purposes are levied and collected, as additional taxes not subject to the above limitation, if no other provision for payment thereof is made: [j[] ... [j[] 2. A tax sufficient to meet all obligations of the City under the State Employees’ Retirement System, the Federal Insurance Contributions Act, or other plan, for the retirement of City Employees, due and unpaid or to become due during the ensuing fiscal year.”
In 1976, City’s voters approved amendments to the charter prohibiting the city council from taking any action which had “the effect of increasing the amount of tax payable” unless approved by a vote of at least three-fourths of the council. The amendments expressly excluded from this supermajority vote requirement increases in the retirement tax.
In June 1978, City’s voters approved a new charter. Some of the provisions which the city council considered “controversial” were presented to the voters as distinct propositions. The remaining provisions of the proposed charter, including those relating to the retirement system and its funding, were combined in “Proposition D.” The “City Attorney’s Impartial Analysis” described Proposition D as follows: “The existing City Charter contains a number of ‘housekeeping’ provisions which will be streamlined by approval of Proposition ‘D.’ The controversial measures, Proposition ‘E,’ ‘F,’ ‘G,’ ‘H,’ and ‘J,’ are in no way affected by the vote on Proposition ‘D.’ There is insufficient space in this analysis to describe in detail each provision of the existing Charter which will be amended by the adoption of Proposition ‘D’ and therefore, a close reading of the text of the proposed amendments is recommended.”
The 1978 charter changed the prior charter by no longer mandating participation in the State Employees’ Retirement System, now the Public [1379]*1379Employees’ Retirement System (PERS). Instead, the new charter merely provides: “The City shall participate in a retirement system.” Additionally, the new charter requires that the council “establish such reasonable compensation and fringe benefits as are appropriate by ordinance or resolution for ... offices, officials and employees except as herein provided.” Consistent with the 1966 charter, the new charter specifies that City may impose excess taxes sufficient to meet all its obligations “for the retirement system in which the City participates, due and unpaid or to become due during the ensuing fiscal year.” As did the earlier one, the new charter imposes a general requirement that increases in taxes must be approved by 75 percent of the council, but again excludes the retirement tax from the supermajority vote.
Some of City’s employees have been members of PERS since 1945; all of them have been members since 1966. Benefits under the plan are funded by a combination of contributions from the public agency employers, contributions from employee members, and earnings from investments made by PERS. The employee contribution rates are set by the Legislature as a percentage of the employee’s salary, while the employer contribution rates are set annually, as determined by actuarial valuations based on the employer’s retirement formula, the makeup of employee groups, and PERS’s earnings on investments.
Since the early 1970’s, virtually all City employees have been represented by employee associations; the associations and City have entered into collective bargaining agreements, known as memoranda of understanding (MOU’s), which establish employee wages, hours, and working conditions, including retirement benefits.
Between 1970 and the adoption of the 1978 charter, City made several changes liberalizing benefits under the PERS contract. It added survivor’s benefits for the families of employees who died prior to retirement, provided for up to four years of military service to count toward PERS benefits, and allowed certain employees’ PERS benefits to be based on the employee’s single highest year of compensation, rather than an average of the employee’s highest three years.
City continued to change its retirement package even after the adoption of its 1978 charter and the passage of Proposition 13. The first of the post-charter changes became effective the same date as Proposition 13. On July 1, 1978, pursuant to previously negotiated MOU’s, City began paying part of its employees’ portion of retirement contributions. During the ensuing years, as part of new MOU’s, City gradually increased the percentage of the employee’s portion of contributions it paid until the point where it now pays the employees’ full PERS contribution.
[1380]*1380In 1987, City also added two new benefits: A “Self-Funded Supplemental Retirement Benefit,” initially provided for all employees, now applies only to employees hired before July 1998. A “Medical Insurance Retirement Fund” permits an employee to continue participating in City’s health insurance program after retirement, with a portion of the premiums subsidized by City.
In 1999, PERS notified City that its retirement plan was “super-funded,” meaning “the actuarial value of assets exceeds the present value of benefits.” As a consequence, PERS substantially reduced City’s employer contribution for fiscal year 1999-2000. Subsequently, PERS advised City that its employer contribution for fiscal years 2000-2001 and 2001-2002 would be zero. But City remained obligated for the other provisions of its negotiated retirement packages, and it continued to fund at least a portion of those other benefits through the retirement tax override contained in the 1978 charter.
Plaintiffs Howard Jarvis Taxpayers Association and one of its members, Charles Scheid, filed this suit. Scheid is a Huntington Beach resident who paid the property tax override under protest. The complaint seeks a refund of that portion of Scheid’s fiscal year 1999-2000 tax override payment that is attributable to retirement benefits, and a declaration prohibiting Huntington Beach from levying a tax override for retirement benefits not already being provided to employees in June 1978.
After trial, the court ruled in plaintiffs’ favor, concluding that the voters of Huntington Beach did not intend their approval of the retirement provisions of the 1978 charter “to commit the City to an indebtedness for future enhancements in the type or level of city employee retirement benefits beyond those to which city employees were entitled at the time of the election.” (Italics added.) The court explained that “[t]he indebtedness approved by Huntington Beach voters prior to July 1, 1978, when they adopted Measure D, was an indebtedness to continue providing all retired, current, and future city employees with the retirement benefits to which city employees were entitled at the time of the election, either through PERS or some other singular retirement system, subject of course to any requirements imposed from time to time by the State Legislature. At the time of the election, the City was providing a PERS pension to all its employees and a PERS survivors’ benefit to its firefighters.” Consequently, in the absence of what it viewed as voter approval for the subsequently added retirement enhancements, the court concluded that allowing City to levy an excess tax to fund those enhancements violated Proposition 13.
[1381]*1381DISCUSSION
Interpretation of Charter
City challenges what it calls the trial court’s “cramped interpretation” of the charter language in its finding that the voters “did not intend their approval of [the new charter] to commit the City to an indebtedness for future enhancements in the type or level of city employee retirement benefits beyond those to which city employees were entitled at the time of the election.” It contends that this conclusion is supported by neither the text of the charter nor its legislative history. Rather, it argues, charter language stating it may impose excess taxes to satisfy its obligations “for the retirement system” clearly shows the voters empowered City to levy an excess tax to pay for any retirement benefit. City’s position does not persuade.
We review measures adopted by the voters in the same manner as we interpret statutes (see Hermosa Beach Stop Oil Coalition v. City of Hermosa Beach (2001) 86 Cal.App.4th 534, 548-549 [103 Cal.Rptr.2d 447]), using a de novo standard (Be v. Western Truck Exchange (1997) 55 Cal.App.4th 1139, 1143 [64 Cal.Rptr.2d 527]). When statutory language is clear and unambiguous, we need not construe its meaning. (Downen’s, Inc. v. City of Hawaiian Gardens Redevelopment Agency (2001) 86 Cal.App.4th 856, 860 [103 Cal.Rptr.2d 644].) Although we regard the language plainly not to support City’s position, its interpretation is plausible if looking at the language in a vacuum. Therefore, because the provisions of the charter arguably are ambiguous, we will engage in statutory construction. (Ibid.)
In interpreting the charter, our charge is “to give effect to the intent of the voters adopting it.” (Diamond International Corp. v. Boas (1979) 92 Cal.App.3d 1015, 1033-1034 [155 Cal.Rptr. 616].) To do so, we must read the language to harmonize with the object and purpose of the new charter. (Id. at p. 1034.) We construe the words from the perspective of the voters, attributing the usual, ordinary, and commonsense meaning to them; we do not interpret them in a technical sense or as terms of art. (Ibid.)
City’s construction of the charter violates these principles in several respects. Throughout its brief it emphasizes the language that provides for an excess tax sufficient to pay for “a// obligations of the retirement system ....” City then strains the language well beyond its plain meaning by concluding that “obligations” are the exact equivalent of “benefits,” stating, “Approval to pay ‘all’ obligations obviously reflects the fact that retirement ‘obligations’— i.e., benefits—may change over time.” (Italics omitted.) A more accurate reading is “all obligations,” “obligations” being the operative word. (Italics added.) City’s obligations do not include benefits added after Proposition 13.
[1382]*1382City of Watsonville v. Merrill (1982) 137 Cal.App.3d 185 [186 Cal.Rptr. 857] (Watsonville) is illustrative. Contrary to City’s claim, Watsonville did not approve an excess tax “to pay for benefits increased after the effective date of Proposition 13.” The case did mention that the city’s contracts with PERS had been amended several times, the last after Proposition 13. But, as plaintiffs correctly point out, there are many reasons PERS contracts are amended other than an increase in benefits. Moreover, Watsonville found “the additional tax in dispute was necessary to discharge the City’s obligation to PERS.” (Id. at p. 194, italics added.) Nothing was said about added benefits.
City relies on Carman v. Alvord (1982) 31 Cal.3d 318 [182 Cal.Rptr. 506, 644 P.2d 192] (Carman) to support its interpretation. However, it is not persuasive when considered in the factual context of our case. There, in 1948 the voters approved a measure for the city to “fully participate” in the state sponsored retirement system, mating the city’s employees “members” of the system. (Id. at p. 322, fn. 2.) The city was empowered to “ ‘levy and collect annually, as contemplated in [the statewide statute], a special tax sufficient to raise the amount estimated by [the City] Council to be required to meet ...’ ” the city’s obligations to the retirement system. (Id. at p. 322, fn. omitted.) After Proposition 13 was passed, the plaintiff challenged the levy of a tax in excess of the 1 percent maximum to fund the amount due PERS. On appeal, the court found the tax was permissible because it was an “[indebtedness approved by the voters prior to July 1, 1978.” (Cal. Const., art. XIII A, § 1, subd. (b) (subdivision (b).)
City stresses the finding in Carman that by approving the city’s participation in PERS and by authorizing a special tax to fund contributions, the voters “[n]ecessarily ... approved all indebtedness to employees, current and future, that would be incurred.” (Carman, supra, 31 Cal.3d at p. 326.) Under the facts in Carman, that was a logical determination. But the conclusion City draws from that holding is not.
It contends the Huntington Beach voters “ ‘obviously understood’ in 1978 that City’s retirement benefits would not remain static ...” and asserts that the rationale in Carman as to new employees “applies with equal force to benefits added [thereafter].” However, nothing in Carman authorizes an excess levy for new benefits extended after the passage of Proposition 13, even for employees hired before that date. In fact, it supports the opposite conclusion.
The Carman court determined that subdivision (b) did not “exempt only traditional, fixed, long-term debt for borrowed funds” as the plaintiff had asserted. (Carman, supra, 31 Cal.3d at pp. 325, 327.) Nor was it restricted to “indebtedness which was fixed and certain when approved.” (Id. at p. 326, [1383]*1383fn. 6.) Instead, the court noted, subdivision (b) “speaks only of the time of approval, not the time an indebtedness is incurred or accrues.” (Ibid.) However, when the “voters empowered [the city] to offer the pension plan provided by PERS[,] they authorized the special tax set by statute insofar as necessary to fund the obligations. [Citation.]” (Id. at pp. 325-326, italics added.)
City seeks to avoid Proposition 13 by entering into contracts with added benefits funded through or in connection with a “retirement system,” classify them as previously approved obligations, and then levy an excess tax to pay for them. Carman cautioned against this, prohibiting “open-ended voter approval, given before Proposition 13, to incur any government expense deemed desirable from year to year and to tax accordingly.” (Carman, supra, 31 Cal.3d at p. 326, fn. 6.) It explained that subdivision (b)’s phrase “ ‘interest and redemption charges’ denotes no more or less than the sums from time to time necessary to avoid default on obligations to pay money, including those for pensions.” (Carman, supra, 31 Cal.3d at p. 328, fn. omitted.) The purpose of subdivision (b) is “to prevent the impairment of contracts approved by the voters in reliance upon the power of the district to levy the tax necessary to fulfill that contract. [Citation.]” (County of Shasta v. County of Trinity (1980) 106 Cal.App.3d 30, 40 [65 Cal.Rptr. 18], italics added.) Thus, Carman upheld only “a levy for a narrowly defined purpose that necessarily would give rise to payment obligations in the future.” (Carman, supra, 31 Cal.3d at p. 326, fn. 6.)
Here, City’s position is a far cry from “narrowly defined.” In the trial court, City asserted that the new charter language gives it the right to levy an excess tax for virtually anything, including “giv[ing] a house ... to every employee as they retire ... [][] ... as long as it’s a retirement related purpose.” City’s construction of the exception created by subdivision (b) eviscerates Proposition 13. As one court explained in another context, “If we were to accept the City’s interpretation ..., we would be turning [Proposition 13] on its head, by narrowly construing the ... requirements and broadly construing the statutory exceptions to it. [Citation.]” (Shapiro v. San Diego City Council (2002) 96 Cal.App.4th 904, 924 [117 Cal.Rptr.2d 631].)
City’s obligation as authorized by the voters at the time Proposition 13 became effective was to participate in a retirement system. It was not to provide every benefit requested by city employees or advocated by the city council. Assume that the obligation was to provide a transportation system for employees, and Toyotas or Buicks were offered at the time Proposition 13 was enacted. No one could reasonably say City was later authorized to levy an excess tax to provide Ferraris. Yet that philosophy is what City would have us validate.
[1384]*1384Under City’s interpretation, it would have virtually unfettered power to spend whatever sum of money and levy excess taxes to obtain the revenue, as long as the expenditure was designated “retirement.” This was one of the very things Proposition 13 was enacted to combat. And the voters of Huntington Beach obviously favored fetters on City’s taxing power. Simultaneously with approving the new charter, 70 percent of them voted in favor of Proposition 13.
We must understand Proposition 13 to be able to properly construe the charter. The Proposition 13 ballot pamphlet stated the measure was “directed against ‘spendthrift politicians’ and as ‘[r]estor[ing] government of, for and by the people.’ [Citation.]” (Kennedy Wholesale, Inc. v. State Bd. of Equalization (1991) 53 Cal.3d 245, 250 [279 Cal.Rptr. 325, 806 P.2d 1360].) Further, its purpose “was to achieve statewide control over escalating local property tax rates.” (City of Rancho Cucamonga v. Mackzum (1991) 228 Cal.App.3d 929, 945 [46 Cal.Rptr.2d 448, 279 Cal.Rptr. 220].) Its raison d’etre was to limit municipalities’ taxing power.
Subdivision (b), which allows for an excess tax necessary to pay for “[indebtedness approved by the voters prior to July 1, 1978,” is an exception to the stringent restrictions of Proposition 13. “An exception to the main premise of a statute is to be strictly construed. [Citation.]” (People v. Superior Court (2002) 97 Cal.App.4th 1222, 1228 [119 Cal.Rptr.2d 170].) Thus, City’s right to tax is subject to the statewide prohibition on excess taxes. (Centex Real Estate Corp. v. City of Vallejo (1993) 19 Cal.App.4th 1358, 1362 [24 Cal.Rptr.2d 48].)
City misses the mark when it asserts there is no evidence to support the trial court’s finding the voters “intended to freeze the status quo when they adopted” the new charter. First, we do not read the trial court’s ruling the way City presents it. More importantly, the argument begs the question. The issue is not whether the voters expressly intended to maintain the status quo or limit retirement benefits to those in existence at the time the new charter was enacted. The voters did not have to specifically intend to limit the benefits; Proposition 13 did that. For any obligations not approved prior to Proposition 13, the tax is automatically capped, regardless of the charter or the voters’ intent. Instead, the voters must intend to authorize a tax in excess of the 1 percent limit for a specific obligation. (Subd. (b).) Preexisting obligations are the exception to Proposition 13; therefore, they must be specific, real, and existing. If they are not, the tax is barred.
Likewise, Proposition 13 prohibits a finding that the voters intended to authorize City to levy a retirement tax in an amount equal to that in effect in June 1978, as City suggests. The voters never approved the amount of the tax. And subdivision (b) speaks of approval of the indebtedness, not the tax.
[1385]*1385City maintains the electorate would not have given it discretion to provide “new” retirement benefits, while at the same time denying it the right to levy an excess tax to pay for them. After all, it continues, the voters knew they would have to pay for those benefits somehow. If their intent was to limit taxing authority, the voters would have specified that limit.
But the voters had no opportunity to set a limit. They did not write the language, nor were they given a choice between provisions with or without limitations. And, as we have noted, the voters did not have to intend to or specifically limit the tax; it was limited by Proposition 13.
Moreover, the words of the charter suggest the voters did intend to limit the authority to tax; the operative language is in a section of the charter entitled “TAX LIMITS.” “[I]t is well established that ' “chapter and section headings [of an act] may properly be considered in determining legislative intent” [citation], and are entitled to considerable weight. [Citation.]’ [Citations.]” (People v. Hull (1991) 1 Cal.4th 266, 272 [2 Cal.Rptr.2d 526, 820 P.2d 1036].) It is consistent with the remaining provisions of the charter to interpret this section title to mean the voters did not intend to give City carte blanche to levy a property tax in excess of 1 percent to pay for all new retirement benefits.
City also argues the voters must have intended the tax to pay for retirement obligations to also fund the “reasonable compensation and fringe benefits” authorized by the new charter. We disagree. Yes, the charter gives City the right to provide fringe benefits and compensation; but it does not obligate it to provide additional retirement benefits. City may provide these benefits; it just cannot fund them using an excess levy. Rather, “the employer can provide for the indebtedness in varying ways.” (Carman, supra, 3 Cal.3d at p. 325.)
Nor is City correct in its assertion that the voters “are presumed to have known” that the PERS contracts had frequently been amended before 1978. The presumption that when voters approve initiatives they are “aware of existing laws and judicial construction thereof’ (In re Lance W. (1985) 37 Cal.3d 873, 890, fn. 11 [210 Cal.Rptr. 631, 694 P.2d 744]) does not extend to factual information such as amendments to contracts.
Additionally, the language of the charter does not lend itself to City’s construction. “As a rule, courts should not presume an intent to legislate by implication. [Citation.]” (Lubner v. City of Los Angeles (1996) 45 Cal.App.4th 525, 529 [53 Cal.Rptr.2d 24].) “ ‘[F]or a consequence to be implied from a statute there must be greater justification for its inclusion than a consistency or compatibility with the act from which it is implied. “A [1386]*1386necessary implication within the meaning of the law is one that is so strong in its probability that the contrary thereof cannot reasonably be supposed.” ’ ” (Woodland Joint Unified School Dist. v. Commission on Professional Competence (1992) 2 Cal.App.4th 1429, 1451 [4 Cal.Rptr.2d 227], italics omitted.) That condition is absent here. Likewise, we reject as pure speculation City’s claim that if the voters had intended to limit the taxing power, someone, i.e., the employee association, would have objected.
The distinction City draws between payments “to” a retirement system and “for” a retirement system is of no consequence. Contrary to its argument, paying “for” a retirement system is not the equivalent of approval to tax for benefits offered after June 1978. So, too, City’s interpretation of the charter term “retirement system” as something “constantly changing” does not translate to voter authorization of a tax to pay for later-added benefits.
City challenges what it describes as “[t]he only factual support” for the decision, i.e., that the proposals relating to retirement were grouped together as part of Proposition D, described in the voter pamphlet as “noncontroversial” “housekeeping” provisions. It complains the trial court’s “unstated premise” is that a provision authorizing an excess tax to pay for future retirement benefits “would have been sufficiently controversial to warrant separate submission to the voters.” That is not how we see it.
Rather, for us to find the voters intended to provide unrestricted power to tax for anything classified as a “retirement benefit,” the ballot measure or the voter pamphlet had to make such an explanation. Courts may assume the ballot materials reflected the voters’ intent in passing the new charter. (Trader Sports, Inc. v. City of San Leandro (2001) 93 Cal.App.4th 37, 49 [112 Cal.Rptr.2d 677].) Here, nothing in Proposition D or the voter information package addressed open-ended tax authority. “Absent some indication that the voters were aware of and intended that result, we cannot adopt a construction that would require that result.” (Woo v. Superior Court (2000) 83 Cal.App.4th 967, 977 [100 Cal.Rptr.2d 156].) City devotes several pages to a discussion of the intent of the charter revision commission and the city council in drafting the new charter language. It stresses, for example, the change from the draft that it would participate in PERS or several different systems, to the final rendition presented to the voters authorizing City to “participate in a retirement system.” It interprets this language to mean the voters gave it authority to select the type of plan and how to fund it, including the excess tax. But, “except in certain ‘rare circumstances’ [citation], ‘the validity of legislative acts must be measured by the terms of the legislation itself, and not by the motives of, or influences upon, the legislators who enacted the measure.’ [Citations.]” (Neecke v. City of Mill Valley (1995) 39 Cal.App.4th 946, 958 [46 Cal.Rptr.2d 266].) Nothing in the record shows the issue of [1387]*1387“flexibility” was presented to the voters, either in the voter material or in Proposition D itself. And we cannot consider something not before the voters. (See Carman, supra, 31 Cal.3d at p. 331, fn. 10 [drafter’s “after-the-fact” explanation of intent does not govern our determination of how the voters understood the provision].)
In sum, subdivision (b) is a safety net; it is not an open checkbook. City’s expansive interpretation cannot be reconciled with Proposition 13, which “change[d] the previous system of real property taxation and tax procedure by imposing important limitations upon the assessment and taxing-powers of state and local government.” (Amador Valley Joint Union High Sch. Dist. v. State Bd. of Equalization (1978) 22 Cal.3d 208, 218 [149 Cal.Rptr. 239, 583 P.2d 1281].) Nor does authorization to participate in a retirement system constitute a prior obligation. “ ‘The term “indebtedness” has no rigid or fixed meaning, but rather must be construed in every case in accord with its context.’ [Citations.]” (Carman, supra, 31 Cal.3d at p. 326.) In this case, “indebtedness” does not encompass benefits City added after the passage of Proposition 13.
Motion for New Trial
City contends the judgment must be reversed, because it requires an impossibility, i.e., PERS’s calculation of the pre- and post-July 1978 benefits. In the alternative, it suggests a new trial on that issue alone. (We deny plaintiffs’ motion to strike the parts of City’s brief dealing with this issue.)
In support of its motion for new trial, City submitted two declarations of Ronald L. Seeling, the Chief Actuary of PERS. He opined that there would be “no practical means to calculate what the City’s PERS employer contribution rate would have been during FY 1999-00 had the City provided only those benefits in existence prior to July 1, 1978.” He further stated that even determining what portion of the employer contributions is attributable to benefits existing at July 1, 1978 “would impose an exceedingly onerous burden on PERS.” He advised the calculations would have to be done “by hand” because the necessary information was not in the database.
However, the amended judgment does not require City to make those calculations for any years before 2000-2001. Therefore, any calculations needed to limit the tax to existing benefits are prospective only.
In denying the motion for new trial, the court discounted this contention, stating: “The court heard the evidence. The court feels that the City has acted improperly .... [T]he argument that this is an impossible situation for PERS or the City to resolve, the court really isn’t buying it. [f] ... [I]t would be [1388]*1388improper not to give the relief requested because the City or PERS is going to have some difficulty in trying to mathematically go back and do what ... the order [requires.]”
The trial court has broad discretion in ruling on a motion for new trial, and we will not reverse absent an abuse of discretion. (Sherman v. Kinetic Concepts, Inc. (1998) 67 Cal.App.4th 1152, 1160 [79 Cal.Rptr.2d 641].) Our review of the record persuades us the court properly exercised its discretion.
Statute of Limitations
City contends the declaratory relief claim is barred by the 30-day statute of limitations set out in Revenue and Taxation Code section 4808. That section provides that a taxpayer may file a declaratory relief action where an illegal or unconstitutional tax directly results from a change in the statute or administrative regulations enacted no more than 12 months before the date the complaint is filed. Thus, City argues, plaintiffs’ action filed in December 1999 was more than 20 years’ overdue.
Plaintiffs counter that the change in the law triggering the illegal tax was the ordinance City passed in August 1999 levying the retirement tax override at issue. We agree. A city ordinance “ ‘is the equivalent of a municipal statute....’ [Citation.]” (California Aviation Council v. City of Ceres (1992) 9 Cal.App.4th 1384, 1391 [2 Cal.Rptr.2d 163].) The action was filed within six months of enactment of the ordinance and is timely.
Modification of Judgment
In an action seeking refund of taxes levied by a city and collected by the county on the city’s behalf, “any judgment rendered for an assessee shall be entered exclusively against the county ...” (Rev. & Tax. Code, § 5146.) Taxes were collected by defendant County of Orange, and it must refund the overpayment.
DISPOSITION
The judgment is modified to direct entry of judgment for refund of the overpayment of tax to Charles Scheid against the County of Orange pursuant to Revenue and Taxation Code section 5146, and, as so modified, the judgment is affirmed. Respondents are awarded their costs on appeal.
Sills, P. J., concurred.
