Opinion
Evidеnce Code section 669.5 requires that in any action challenging the validity of certain growth control ordinances, the city or county enacting the ordinance must bear the burden of proof that the ordinance is “necessary for the protection of thе public health, safety, or welfare” of its population. 1 The question in this appeal is whether section 669.5 is applicable in an action attacking a city charter amendment adopted by initiative and an ordinance implementing the amendment, both еnacted before the effective date of the statute. We conclude that the statute applies, reverse the judgment, and remand for trial.
Factual and Procedural Background
In March 1973 the voters of the City of Alameda (the City) amended its charter with a policy declaration that no multiple dwelling units should be built in the City, except for the replacement of certain existing low-cost *910 housing units and a proposed senior citizens low-cost housing complex. (Alameda City Charter, art. XXVI, §§ 26-1, 26-2.) The City Council implemented the charter amendment, which was commonly known as Measure A, by adding to the Municipal Code chapter 4 of title 11 (the ordinance). The ordinance defines the prohibited multiple dwelling unit as a residential building to be used by three or more families or living groups, living independently of each other. (Alameda Mun. Code, tit. XI, ch. 4, § 11-421(b).)
In 1987 plaintiffs Edward J. Murphy, Madlyn K. Murphy, and Elisabeth Lillie filed an amended complaint for declaratory and injunctive relief against the City and others; their first two counts attacked Measure A and the ordinance as unconstitutional.
Plaintiffs moved for summary adjudication of issues, seeking а determination that section 669.5, which became effective in January 1981, applied to those counts. The trial court found no indication that the Legislature intended the statute to be retroactive and concluded it did not apply. Thereafter, the parties stipulated to entry of judgment in favor of defendants to permit an appeal by plaintiffs; the parties agreed that should the trial court’s ruling on section 669.5 be reversed, a trial on the merits would be required. Judgment pursuant to the stipulation was entered in favor of defendants. The foregoing procedure to facilitate plaintiffs’ appeal was patterned after that approved by the Supreme Court in

Discussion
A. The Scope of Section 669.5
Under the traditional rule, a party challenging the constitutionality of an ordinance has the burden to present еvidence and documentation that the legislation is not reasonably related to the public welfare of those whom it significantly affects. (See, e.g.,
Associated Home Builders etc., Inc.
v.
City of Livermore
(1976)
*911 Section 669.5 provides in relevant part: “(a) Any ordinance. . . which (1) directly limits, by number, the building permits that may be issued for residential construction or the buildable lots which may be developed for residential purposes ... is presumed to have an impact on the suрply of residential units available in an area which includes territory outside the jurisdiction of the city . ... [IQ (b) With respect to any action which challenges the validity of an ordinance specified in subdivision (a) the city . . . enacting the ordinance shall bear the burden of рroof that the ordinance is necessary for the protection of the public health, safety, or welfare of the population of the city . . . .” (Italics added.)
Defendants insist that section 669.5 is inapplicable on its face to Measure A and the ordinance because they do not impose any numerical limits on permits or lots, but simply regulate the type of units which may be constructed. Little need be said about this argument. When the Legislature enacted section 669.5, it was concerned with local government ordinanсes which severely restrict the number of available housing units. (Stats. 1980, ch. 1144, § 1, p. 3703.) It is the practical effect of such ordinances, not their literal terms, which dictates whether the statute applies. (See
Camarillo, supra,
B. Prospective or Retroactive Application
Underlying the trial court’s ruling is its assumption that application of section 669.5 in this сase would give the statute retroactive effect. Plaintiffs disagree, arguing that the statute concerns rules of evidence at future trials and is therefore prospective.
Courts have consistently recognized the principle that a new statute addressing the conduct of trials may actually be prospective in nature when applied to a trial occurring after its effective date, even though the trial deals with facts existing prior to that date.
(Tapia
v.
Superior Court
(1991)
This principle does not include statutes which do not simply аddress the conduct of trials, but which change the legal consequences of the parties’ past conduct, as by imposing new and different liabilities based on that conduct. Although courts at times use the terms “substantive” and “procedural” to determine whether a statutе alters the legal consequences of past events, what is important is the law’s effect, not its label or form.
(Tapia
v.
Superior Court, supra,
53 Cal.3d at pp. 288-291.) A statute which takes a seemingly procedural form and uses evidentiary language concerning burdens of proof may in effect alter or destroy a preexisting substantive right by imposing an evidentiary requirement with which it is impossible to comply. (See, e.g.,
In re Marriage of Buol
(1985)
Defendants argue that apрlication of section 669.5 to this action would change the legal consequences of past events because the City would have to prove that regional housing needs were balanced against the City’s need for Measure A and the ordinance when they were enacted in 1973. Meeting that burden would be impossible, defendants claim, because at that time cities were not obliged to consider regional housing needs in their local planning. (See generally, Gov. Code, § 65580 et seq.)
The most obvious flaw in defendants’ argument is its рremise that application of section 669.5 would require proof of circumstances in 1973. The statute directs that in any action challenging the validity of a growth control ordinance, the city or county shall bear the burden of proof that the ordinance “is” necessary, not that it was necessary at the time it was enacted. As applied in that manner, the statute does not invalidate previously enacted ordinances; instead, it simply subjects such ordinances to a presumption of impact on the housing supply аnd places on the local entity a new burden of proof. (See
Camarillo, supra,
Because section 669.5 addresses the conduct of trials and dоes not change the legal consequences of the parties’ past conduct, its operation is prospective; therefore, the trial court erred in concluding it was inapplicable in this action.
C. Legislative Intent
Plaintiffs argue in the alternative that even if application of section 669.5 in this action is retroactive in effect, the Legislature intended the statute to apply retroactively. We agree.
A statute is presumed to operate prospectively absent an express legislative declarаtion of retroactivity or some other clear indication that retroactive application was intended.
(Evangelatos
v.
Superior Court
(1988)
Although the initial clause of section 669.5, subdivision (b), does state that a city or county shall bear the burden of proof in “any action” challenging the validity of specified ordinances, that broad general language, standing alone, would not be sufficient to establish legislative intent for retroactivity.
(Evangelatos
v.
Superior Court, supra,
The purpose of subdivision (d) of section 669.5 was considered first in
Lee
v.
City of Monterey Park
(1985)
A similar statutory analysis is appropriate here. By expressly declaring that the section should not apply only to certain ordinances adopted by initiative or referendum adopted prior to its effective date, the Legislature impliedly indicated that it shоuld apply to all other ordinances, whether adopted by legislative bodies or by the voters, including all ordinances adopted by initiative prior to its effective date but not specifically exempted. Any other conclusion would render subsections (1) and (2) of section 669.5, subdivision (d) superfluous and meaningless. 2
We have not overlooked the statements in
Camarillo, supra,
D. Applicability of Section 669.5 to Ordinances Enacted to Implement Charter Provisions
Defendants’ final argument also merits little discussion. They argue that because the statute by its express terms refers only to “ordinances,” it is inapplicable to the City’s charter amendment; defendants then claim that the statute is necessarily inapplicable to its ordinance as well, because it was *915 enacted only to implement the charter amendment. Defendants cite no authority in support of this proposition, and nothing in the language of the statute or its legislative history suggests that the Legislature intended to exempt ordinances enacted by charter cities from the application of section 669.5.
Disposition
The judgment is reversed, and the matter remanded for a trial on the merits.
Newsom, J., and Dossee, J., concurred.
Respondents’ petition for review by the Supreme Court was denied March 11, 1993.
Notes
Unless otherwise indicated, all further stаtutory references are to the Evidence Code.
Our conclusion is based on the language of the statute. Therefore, we need not act on defendants’ motion to strike a legislator’s recently prepared declaration, which was submitted with plaintiffs’ reply brief.
