HFH, LTD., Petitioner, v. THE SUPERIOR COURT OF LOS ANGELES COUNTY, Respondent; CITY OF CERRITOS et al., Real Parties in Interest; VON'S GROCERY COMPANY, Petitioner, v. THE SUPERIOR COURT OF LOS ANGELES COUNTY, Respondent; CITY OF CERRITOS et al., Real Parties in Interest, 15 Cal. 3d 508

Opinion TOBRINER, J. We face in these mandate proceedings the narrow issue of whether a complaint alleging that a zoning action taken by a city council reduced the market value of petitioners’ (hereafter plaintiffs) land states a cause of action in inverse condemnation; we conclude that it does not. We also face numerous amici, some of whom urge on us significant changes in the law of liability, and compensation in public land use regulation; we have concluded that neither the state and federal Constitutions nor public policy compel or counsel these changes.

We take the facts in this case from the allegations of the complaints, assuming as we must the truth of any properly pleaded factual allegations. (E.g., Serrano v. Priest (1971) 5 Cal.3d 584, 591 [96 Cal.Rptr. 601, 487 P.2d 1241, 41 A.L.R.3d 1187].) Plaintiffs, a limited partnership (HFH) and a Delaware corporation (Von’s), contracted to purchase the parcel in question from a common grantor. At the time the plaintiffs entered this contract with their grantor, the land in question lay in an agricultural zone and possessed no improvements of any kind.

Plaintiffs conditioned the sale upon the grantor’s ability to procure commercial zoning for the 5.87-acre tract; the City of Cerritos (the real party in interest) “in the latter part of the year 1965 or the early part of 1966” did classify the property as commercial, and in 1966 the plaintiffs became the owners of the parcel, according to the allegations of the complaint. Plaintiffs thereafter submitted, and the city approved, a parcel map on which the plaintiffs subdivided the property in a manner appropriate for commercial uses.

Subsequently, however, a period of some five years elapsed; during that time plaintiffs do not claim any development or establishment of a more intensive use of the land. In July 1971, with the land still in this undeveloped state, according to the allegations before us, the city placed a moratorium upon more intensive uses of the property by temporarily zoning it as agricultural, the classification it had borne before plaintiffs acquired it. Plaintiffs do not allege that this moratorium interfered with any use of the land which they then planned nor do they allege that they then challenged this reclassification.

In October 1971, the city adopted a general plan indicating that some land in the area of plaintiffs’ properties was appropriate for “neighborhood commercial uses,” but did not alter the agricultural classification of plaintiffs’ tracts. The 1971 general plan designated the bulk of the land in the area of plaintiffs’ properties for “low density residential” uses. (City of Cerritos October 1971 General Plan Map; Evid.

Code, § 452, subd. (b).) Having apparently concluded that their interests would best be served by selling rather than developing the land, plaintiffs in early 1972 entered into a $400,000 contract of sale with Diversified Associates, Inc. (not party to this action) conditioned upon the reclassification of the tract as commercial. In an attempt to bring about the condition which would enable them profitably to sell their land, plaintiffs applied to the planning commission for commercial zoning of the tract.

Both the commission and the city council, to which plaintiffs took an appeal, rejected this application, and instead zoned the property as single family residential. Concurrently with taking this action, the city zoned as commercial other properties on different corners of an intersection on which plaintiffs’ land abuts. Plaintiffs, of course, had hoped to secure for their land a commercial classification in order to effectuate the conveyance of the land under the conditions of the contract of sale with Diversified Associates, Inc.

Plaintiffs allege that the situation of their properties rendered them “useless” for single family residential purposes; they do not, however, allege that the properties are useless for other purposes consonant with the zoning categoiy in which they now lie. As a consequence, according to plaintiffs, their land, which they purchased for some $388,000 and hoped to sell for $400,000, suffered a decline in market value to $75,000. The trial court sustained a demurrer without leave to amend to plaintiffs’ cause of action in inverse condemnation and plaintiffs sought review. 1.

Inverse condemnation does not lie in zoning actions in which the complaint alleges mere reduction of market value. The courts of this state have recognized the constitutional values served by actions in inverse condemnation and have not hesitated to validate complaints appropriately employing this theory of recovery. At the same time, we have recognized mandamus as the proper remedy for allegedly arbitrary or discriminatory zoning, and have in appropriate cases struck down land use restrictions which suffered from procedural or substantive deficiencies.

We have never, however, suggested that inverse condemnation lay to challenge a zoning action whose only alleged effect was a diminution in the market value of the property in question. (E.g., Morse v. County of San Luis Obispo (1967) 247 Cal.App.2d 600 [55 Cal.Rptr. 710].) While this state of the law is sufficiently clear to admit of little doubt, we shall briefly review its development and basis. Zoning developed slowly in the latter part of the 19th century.

In its early stages it was frequently indistinguishable from the power to abate public nuisances, but the first decades of this century saw the enactment of more comprehensive zoning laws and the development of the concept of city planning. Shortly after these changes began to take effect, challenges in both state and federal courts raised the question of the constitutionality of these restrictions of the individual’s previous ability to do with his land what he chose, bounded only by the laws of public and private nuisance.

While the legal context in which this question arose differed from case to case, the courts of this state and the United States Supreme Court firmly rejected the notion that the diminution of the value of previously unrestricted land by the imposition of zoning could constitute a taking impermissible in the absence of compensation. We have long adhered to that position. To demonstrate the settled nature of the issue before us we point out that the United States Supreme Court faced the same question in the first major constitutional challenge to modern zoning to come before it. (Euclid v.

Ambler Realty Co. (1926) 272 U.S. 365 [71 L.Ed. 303, 47 S.Ct. 114, 54 A.L.R. 1016].) Tendering allegations almost identical to those urged here, the appellee in Euclid claimed that “the tract of land in question is vacant and has been held for years for the purpose of selling and developing it for industrial uses, for which it is especially adapted, being immediately in the path of progressive industrial development; that for such uses it has a market value of about $10,000 per acre, but if the use be limited to residential purposes the market value is not in excess of $2,500 per acre. . . .” (Id. at p. 384 [71 L.Ed. at p. 309].) The court upheld the zoning against the claim that it constituted a taking of the property in question, settling some half century ago the question in the instant case.

The record of this court stands equally clear. In one of the seminal zoning cases coming before us, in considering and rejecting a contention that a zoning ordinance forbidding the establishment of a nonconforming use in a residential area unconstitutionally deprived the landowners of their property, we quoted with approval the following language of the Wisconsin Supreme Court: “ ‘It is thoroughly established in this country that the rights preserved to the individual by these constitutional provisions are held in subordination to the rights of society.

Although one owns property, he may not do with it as he pleases any more than he may act in accordance with his personal desires. . . . [incidental damages to property resulting from governmental activities, or laws passed in the promotion of the public welfare are not considered a taking of the property for which compensation must be made.’ (Carter v. Harper [1923] 182 Wis. 148 [, 153]. . . .)” (Miller v.

Board of Public Works, supra, 195 Cal. 477, 488.) In an attempt to escape the clear import of such rulings plaintiffs emphasize that their complaint sounds in inverse condemnation, and that they therefore need only show some diminution in value rather than the arbitrary or confiscatory action imposed by the line of cases they seek to avoid. Several appellate courts in California have considered and rejected precisely this contention. The Court of Appeal in Morse v.

County of San Luis Obispo, supra, 247 Cal.App.2d 600, spoke as follows in affirming a judgment of dismissal following the sustaining of a demurrer to a complaint seeking damages in inverse condemnation for the down-zoning of property: “Plaintiffs are apparently attempting to recover profits they might have earned if they had been successful in getting their land rezoned to permit subdivision into small residential lots, but landowners have no vested right in existing or anticipated zoning ordinances. (Anderson v.

City Council [1964] 229 Cal.App.2d 79, 88-90 [40 Cal.Rptr. 41].) A purchaser of land merely acquires a right to continue a use instituted before the enactment of a more restrictive' zoning.[] Public entities are not bound to reimburse individuals for losses due to changes in zoning, for within the limits of the police power ‘some uncompensated hardships must be borne by individuals as the price of living in a modern enlightened and progressive community.’ (Metro Realty v.

County of El Dorado [1963] 222 Cal.App.2d 508....)” (247 Cal.App.2d at pp. 602-603; italics added.) We have only recently reaffirmed this principle in Selby Realty Co. v. City of San Buenaventura, supra, 10 Cal.3d 110; we held in that case that a landowner could not employ inverse condemnation to challenge a zoning ordinance which required him to dedicate part of his land to the city as a condition of receiving a building permit; “The sixth cause of action sounds in inverse condemnation and alleges that the city has ‘taken’ plaintiff’s property without compensation.

Again, insofar as this cause of action is based upon the adoption of the general plan, there is no ‘taking’ of the property....” (10 Cal.3d at pp. 127-128.) Plaintiffs’ amici curiae, however, strenuously argue that California Constitution,

article I,

section 19 [former

article I,

section 14], which provides that “[p]rivate property may be taken or damaged for public use only when just compensation . . . has first been paid. . . .” (italics added) requires a ruling in their favor. Emphasizing the italicized words, plaintiffs contend first, that the California Constitution provides wider protection than the federal, and second, that the city in enacting the challenged zoning ordinances “damaged” their property and must therefore pay compensation. Only the first of these contentions is accurate.

This court has recognized the broader protections granted landowners by the addition of “or damaged” to the language of our state’s compensation clause. (Albers v. County of Los Angeles (1965) 62 Cal.2d 250 [42 Cal.Rptr. 89, 398 P.2d 129]; Reardon v. San Francisco (1879) 66 Cal. 492 [6 P. 317]; cf. County of San Diego v. Miller (1975) 13 Cal.3d 684 [119 Cal.Rptr. 491, 532 P.2d 139].) Yet in arguing that the additional phrase covers this case, plaintiffs mistake its meaning.

Intended to reach situations in which government activity damaged land without taking it, the provision in question does not apply to this case, in which undamaged land has allegedly suffered only a diminution of market value due to zoning action. Plaintiffs fail to distinguish between the “damaged” property which is a requisite for a finding of compensability and the “damages” by which courts measure the compensation due.

Reasoning backwards, plaintiffs erroneously contend that since they can calculate damages (by measuring decline in market value), they must have been “damaged” within the meaning of the state Constitution. Because a zoning action which merely decreases the market value of property does not violate the constitutional provisions forbidding uncompensated taking or damaging, the trial court correctly sustained without leave to amend the demurrer to the cause of action in inverse condemnation. (Cal. Const., art. I, § 19 [former art. I, § 14].) 2. Plaintiffs may not seek damages in their pending mandate action.

Plaintiffs also urge, alternatively to the proposition that inverse condemnation lies for any reduction in market value induced by zoning, the desirability of interim damages incident to the mandate action for which the trial court granted leave to amend. They argue that even if they ultimately succeed in their efforts to obtain a court decision invalidating the challenged zohing ordinance, they will still suffer an uncompensated loss of use of the property in question during the period between the enactment of the challenged ordinance and its demise.

Arguing by implicit analogy to tort law, they urge that invalidation of the offending zoning ordinance will not suffice to compensate them for the damage they suffered by reason of its existence. In so arguing, however, they overlook the distinction between a tort suit and a mandate action: the former enables the wronged plaintiff to recover compensatory damages; the latter permits a party suffering from improper governmental action to correct administrative abuse. The cases have long acknowledged this distinction, one deeply rooted in the theory of our polity.

Courts have thus recognized that “[o]f course, it is not a tort for Government to govern. . . .” (Dalehite v. United States (1952) 346 U.S. 15, 57 [97 L.Ed. 1427, 1452, 73 S.Ct. 956] (Jackson, J., dissenting); Muskopf v.

Corning Hospital Dist. (1961) 55 Cal.2d 211, 220 [11 Cal.Rptr. 89, 359 P.2d 457].) Justice Jackson’s mot expresses both a principle of law and a necessity of rational government; both constitutional and institutional understandings require that legislative acts, even if improper, find their judicial remedy in the undoing of the wrongful legislation, not in money damages awarded against the state. (Cf. City & County of San Francisco v. Cooper (1975) 13 Cal.3d 898 [120 Cal.Rptr. 707, 534 P.2d 403]; Fletcher v.

Peck (1810) 10 U.S. (6 Cranch) 87 [3 L.Ed. 162].) Thus acts within the area of legislative or administrative discretion have long enjoyed the shelter of immunity from tort liability; mere ministerial and “operational” acts, but not “basic policy decisions,” have led to governmental tort liability. (Johnson v.

State of California (1968) 69 Cal.2d 782, 793 [73 Cal.Rptr. 240, 447 P.2d 352].) This distinction finds expression directly relevant to the instant case in the California Tort Claims Act, which provides that “[a] public entity is not liable for an injury caused by adopting or failing to adopt an enactment. . . .” (Gov. Code, § 818.2.) The zoning ordinance of which plaintiffs complain is, of course, an “enactment” within the meaning of

section 818.2. (Gov. Code, § 810.6.) We have recently held that an analogous tort immunity for the denial of a building permit (Gov. Code, § 818.4) constituted specific legislation qualifying the general rule that one may append a damage claim to a mandate action (Code Civ. Proc., § 1095). (State of California v. Superior Court (Veta Co.), supra, 12 Cal.3d 237, 244-247.) Plaintiffs suggest no distinction between Government Code

section 818.2, which confers immunity for legislation, and Government Code

section 818.4, which protects building permit decisions; thus Veto’s holding applies equally to this case. Nor may plaintiffs avoid the clear meaning of Government Code

section 818.2 and Veta by arguing that the damage claim sounds in inverse condemnation rather than in tort. The fallacy in the argument inheres in its failure to recognize that inverse condemnation lies only for a taking or damaging, while improper zoning actions may generally be attacked only by mandate. As we have shown above, plaintiffs have not alleged facts showing a taking or damaging; plaintiffs therefore may not add a damage claim to their pending mandate action. 3.

Although amici argue that “fairness” requires that inverse condemnation lie to challenge zoning actions, both considerations of policy and the limitations of judicial institutions lead to a contrary conclusion. Numerous amici who have entered this case on behalf of the plaintiffs urge that the constitutional values of “fairness” protected by the compensation clauses of the state and federal Constitutions require us to hold that inverse condemnation lies for any zoning action which substantially reduces the market value of any tract of land.

Without attempting a detailed discussion of the many points raised by amici or a review of the still more voluminous secondary literature on the taking issue, we shall briefly indicate the grounds for our declining to do so. In this case, as in most instances, zoning is not an arbitrary action depriving someone of property for the purpose of its use by the public or transfer to another; rather it involves reciprocal benefits and burdens which the circumstances of this case well illustrate.

The shopping center which plaintiffs seem at various times to have contemplated erecting, would derive its value from the existence of residential housing in the surrounding area. That residential character of the neighborhood, we may assume, results in part from the residential zoning of the area around the tract in question.

Plaintiffs in this case therefore find themselves in a somewhat uncomfortable position: they wish to reap the benefit in the form of higher market values of their land, of the restrictive zoning on other properties,. but do not wish to bear the reciprocal burden of such zoning when it applies to'their property. They thus would avoid the enforcement of residential zoning on their property while benefiting from its enforceability as to other property.

The long settled state of zoning law renders the possibility of change in zoning clearly foreseeable to land speculators and other purchasers of property, who discount their estimate of its value by the probability of such change. The real possibility of zoning changes for the tract in question finds ample demonstration in plaintiffs’ insistence that their grantor procure such a change before conveying the land to them. Having obtained the benefits of such rezoning, but having failed to take advantage of it by building, they now assert that the termination of such rezoning rendered the city liable in damages.

A distinguished commentator has thus described plaintiffs’ situation: “[They] bought land which [they] knew might be subjected to restrictions; and the price [they] paid should have been discounted by the possibility that restrictions would be imposed.

Since [they] got exactly what [they] meant to buy, it can perhaps be said that society has effected no redistribution so far as [they are] concerned, any more than it does when it refuses to refund the price of [their] losing sweepstakes ticket.” (Michelman, Property, Utility, and Fairness: Comments on the Ethical Foundations of “Just Compensation” Law (1967) 80 Harv.L.Rev. 1165, 1238; see also Berger, A Policy Analysis of the Taking Problem (1974) 49 N.Y.U.L.Rev. 165, 195-196.) We are urged in this case to redefine the state and federal constitutional requirements of just compensation and to require payment for any zoning action which results in the substantial diminution of market value.

That we do not do so reflects less our belief that no problems exist with the present law in this area than our conviction that legislative rather than judicial action holds the key to. any useful reform. The welter of proposals for action to remedy the inequities in the scheme of land use regulation which fall short of invoking constitutional protection bear ample witness to the ferment in this area. Without passing on the desirability or legality of any of the proposed plans, we note that almost without exception they require legislative action for their implementation.

The complexity of the schemes proposed and the administrative machinery required for their effectuation obviously exceed anything readily feasible as a judicial remedy. Thus even if we were wholeheartedly to concede the wisdom of these plans, they would lie beyond our remedial powers.

Finally, we note that our conclusion in no sense turns on the verbal distinction between “taking” and “police power.” While these terms have a venerable history in discussions of this question, at best they have served as a shorthand method of indicating the result; neither hard nor easy cases are decided by such merely verbal lines. Rather, the far more basic considerations of reciprocity discussed above have shaped the decisions in this area, decisions which reconcile property rights and social needs.

Plaintiffs in this case desire a change in long standing principles of the law of just compensation; they ask that we hold municipal zoning bodies liable for full compensation for any fall in market price due to zoning actions. Yet plaintiffs can cite no case and little by way of other considerations to support their claim of entitlement to compensation by reason of a change in zoning. Hoping to build a shopping center, they purchased a tract previously zoned as agricultural land.

For reasons which do not appear in the record, they did not build for five years, although no zoning impediments are alleged to have existed. Now they desire to sell that land at a profit to yet another developer and complain that the city has in the meantime concluded that its interests would best be served by residential rather than commercial development of the tract in question. Unable to make the desired profit from the sale of their land, they now seek to recoup it from the city; in so doing they mistake the law.

Zoning and other land use regulation, long an established feature of our lives, expresses both a concern for our present quality of life and our collective fiduciary responsibility to the future; that it bears this weight and expresses this concern does not mean that; it may fall short of constitutional standards. These considerations do, however, caution us not capriciously to discard established constitutional boundaries in this area. The alternative writs are discharged, and the peremptory writs denied. Wright, C. J., McComb, J., Mosk, J., Sullivan, J., and Richardson, J., concurred.

The two cases before us originated in separate lawsuits concerning the same parcel of land. All parties agree that they present identical legal issues; they were consolidated in the Court of Appeal for this reason, and we shall hereafter refer to them as a single proceeding. Plaintiffs also complain of the deprivation “of any reasonably beneficial use of . . . said properties commensurate with its value.” In the same

section of their complaints, however, they allege a remaining fair market value of $75,000. The substantial value of their land rebuts the allegation that they cannot enjoy any reasonably beneficial use of it. As to use “commensurate with value,” we note the tautological quality of this statement: “Value” is of course not an objective quality, but a social attribute of legal rights.

Only if we concluded that plaintiffs enjoyed a vested right in a previous zoning classification would the city’s action have deprived them of a use commensurate with value; our courts have, however, clearly and frequently rejected the position that landowners enjoyed a vested right in a zoning classification. (E.g., Morse v. San Luis Obispo County (1967) 247 Cal.App.2d 600 [55 Cal.Rptr. 710].) The trial court also sustained demurrers to other counts, granting leave to amend for purposes of adding a cause of action in mandate.

These counts are not before us, for plaintiffs seek review only of the order sustaining the demurrer to the inverse condemnation count and pray for a writ of mandate directing the trial court to overrule that demurrer. At oral argument plaintiffs and their amici curiae stressed the trial court’s failure to allow amendment of their pleading. We recognize, of course, the requirement of liberality in permitting amendment of pleadings “in furtherance of justice.” (Code Civ. Proc., § 473; e.g., Klopstock v.

Superior Court (1941) 17 Cal.2d 13, 19-20 [108 Cal.Rptr. 906, 135 A.L.R. 318].) Nothing in this policy of liberal allowance, however, requires an appellate court to hold that the trial judge has abused his discretion if on appeal the plaintiffs can suggest no legal theory or state of facts which they wish to add by way of amendment.

Speaking to circumstances like those of the instant case, we have said: “[T]he burden is on the plaintiff to demonstrate that the trial court abused its discretion. [Citations omitted.] Plaintiff must show in what manner he can amend his complaint and how that amendment will change the legal effect of his pleading.” (Cooper v. Leslie Salt Co. (1969) 70 Cal.2d 627, 636 [75 Cal.Rptr. 766, 451 P.2d 406]; Filice v.

Boccardo (1962) 210 Cal.App.2d 843, 847 [26 Cal.Rptr. 789].) Thus plaintiffs, while implying that they might in an unspecified manner amend their complaint to state a cause of action, fail to suggest any relevant facts with which they could supplement their pleading. We shall therefore determine this question below without reference to other possible facts which might enable them successfully to state a cause of action in inverse condemnation.

Plaintiffs have failed to allege any existing use that was in nonconformity with the residential zoning classification now in effect; as far as the allegations of their complaint disclose, the'land remains in the same state as the day the plaintiffs acquired it.

Thus we need not here consider the question of a nonconforming use which the zoning authority seeks to terminate or remove; for plaintiffs have alleged that they enjoy a vested right, not in an existing use, but in a mere zoning classification on vacant land. This case therefore raises no issue of the constitutionality of a zoning regulation which requires the termination of an existing use. (Cf. Livingston Rock etc. Co. v.

County of Los Angeles (1954) 43 Cal.2d 121, 127 [272 P.2d 4].) Plaintiffs argue that Selby is distinguishable because that case involved a uniform zoning classification while in the instant case plaintiffs have tendered allegations of discriminatory zoning classification.' The asserted distinction lacks substance. Plaintiffs have a remedy in a mandate action against discriminatory zoning. (Code Civ. Proc., § 1085.) Both their complaint and their briefs in this case, however, urge that the injury constituting the taking was the reduction .in market value of the land.

If such a reduction constituted an injury, it would occur regardless of the legality of the zoning action occasioning it; indeed we have held that the wrongfulness of the state’s action is irrelevant in an inverse condemnation case. (E.g., Holtz v. Superior Court (1970) 3 Cal.3d 296. 302 [90 Cal.Rptr. 345, 475 P.2d 441].) Thus, if plaintiffs have suffered an injury cognizable under California Constitution,

article I,

section 19, they stand entitled to compensation regardless of the public agency’s wrongfulness in causing the injury. If, on the other hand, the city has acted arbitrarily or discriminatorily in passing the zoning ordinance of which they complain, plaintiffs stand entitled to relief by administrative mandate. Since governmental fault is irrelevant in an inverse condemnation action. Selby's discussion of the impropriety of inverse condemnation as a remedy for allegedly improper zoning is apposite to the instant case.

Neither Selby nor this case presents the distinct problems arising from inequitable zoning actions undertaken by a public agency as a prelude to public acquisition (Klopping v. City of Whittier (1972) 8 Cal.3d 39 [104 Cal.Rptr. 1, 500 P.2d 1345]; Peacock v. County of Sacramento (1969) 271 Cal.App.2d 845 [77 Cal.Rptr. 391]); or from zoning classifications invoked in order to evade the requirement that land used by the public must be acquired in eminent domain proceedings (Sneed v. County of Riverside (1963) 218 Cal.App.2d 205 [32 Cal.Rptr. 318]).

Thus in Klopping the city in question made public announcements that it intended to acquire the plaintiff’s land, then unreasonably delayed commencement of eminent domain proceedings, with the predictable result that the property became commercially useless and suffered a decline in market value. We held only that the plaintiff should be able to include in his eminent domain damages the decline in value attributable to this unreasonable precondemnation action by the city.

The case thus in no way resembles the instant one, in which plaintiffs make no allegations that the city intends to condemn the tract in question. Similarly in Peacock the county had refused to permit any development of the land in question (barring even the growth of most vegetation), while assuring the owner that the restrictions were of no consequence because the county intended to acquire the land for an airport.

When, after denying the owner any use of his property for five years, the county renounced its intent to acquire the land, the Court of Appeal affirmed a trial court finding that “ ‘ [t]he exceptional and extraordinary circumstances heretofore enumerated . . . constituted a take [s/c] of the subject property by inverse condemnation.’ ” (271 Cal.App.2d at p. 854.) Again one sees that the down-zoning rises to a taking only in connection with inequitable precondemnation actions by the public agency.

Finally, the cases hold that a public agency may not use a zoning ordinance to the requirement that the state acquire property which it uses for public purposes. Thus in Sneed, the county, rather than acquiring land for an air navigation easement, simply enacted a zoning ordinance forbidding any structure or vegetation more than three inches high and proceeded to operate flights over the area thus restricted. The Court of Appeal held that the plaintiff had stated a cause of action in inverse condemnation. Unlike the instant case, Sneed involved a zoning ordinance creating an actual public use of the property.

Thus, while we have not hesitated to afford individuals the full measure of the protection indicated by the history of

article I,

section 19, no California case has ever interpreted the “or damaged” phrase of our state Constitution to cover mere diminution of market value of property due to zoning action. This case does not present, and we therefore do not decide, the question of entitlement to compensation in the event a zoning regulation forbade substantially atI use of the land in question. We leave the question for another day. Citing County of San Diego v.

Miller (1975) 13 Cal.3d 684 [119 Cal.Rptr. 491, 532 P.2d 139], plaintiffs and their amici argue that the only consideration in this case relates to the “fairness” of the principle for which they contend; to this somewhat broad argument two answers present themselves. First, plaintiffs ignore the context of San Diego; the issue in that case was the distribution of a condemnation award which all conceded to be appropriate, not whether otherwise lawful state action constituted a “taking." Second, on a more basic level, we are deeply mindful of the “basic equitable principles of fairness” (United States v.

Fuller (1973) 409 U.S. 488, 490 [35 L.Ed.2d 16, 20. 93 S.Ct. 801]) which shape this area of the law. We set forth below some of the considerations which cast doubt on plaintiffs’ claim even under this broad and only tenuously legal rubric of constitutional “fairness.” E.g., Berger, A Policy Analysis of the Taking Problem (1974) 49 N.Y.U.

L.Rev. 165; Bosselman et al., The Taking Issue (1973); Costonis, Development Rights Transfer: An Exploratory Essay (1973) 83 Yale L.J. 75; Costonis, The Chicago Plan: Incentive Zoning and the Preservation of Urban Landmarks (1972) 85 Harv.L.Rev. 574; Hagman, A New Deal: Trading Windfalls for Wipeouts (1974) 40 Planning 9; Michelman, Property, Utility, and Fairness: Comments on the Ethical Foundations of “Just Compensation” Law (1967) 80 Harv.L.Rev. 1165; Rose, A Proposal for the Separation and Marketability of Development Rights as a Technique to Preserve Open Space (1974) 2 Real Est.L.J. 635; Van Alstyne, Taking or Damaging by Police Power: The Search for Inverse Condemnation Criteria (1970) 44 So.Cal.L.Rev. 1.

As one of plaintiffs’ amici has written in another context, “[WJhile one can conceptually separate windfalls caused by government [e.g., by zoning actions] from those caused by the community, they are very hard to disentangle and measure.” (Hagman, A New Deal: Trading Windfalls for Wipeouts (1974) 40 Planning 9; see also Costonis, Development Rights Transfer: An Exploratory Essay, supra, 83 Yale L.J. 75: Rose, A Proposal for the Separation and Marketability of Development Rights as a Technique to Preserve Open Space, supra, 2 Real Est. L.J. 635.) See footnote 18, ante. E.g., Costonis.

L.J. 635; Berger, A Policy Analysis of the Taking Problem, supra, 49 N.Y.U.L.Rev. 165; Michelman, Property, Utility and Fairness: Comments on the Ethical Foundations of “Just Compensation” Law, supra, 80 Harv.L.Rev. 1165, 1252: “[T]he courts recognize that they cannot, through the enunciation of doctrine which decides cases, adequately stake out the limits of fair treatment; that if the quest for fairness is left to a series of occasional encounters between courts and public administrators it can but partially be fulfilled; and that the political branches, accordingly, labor under their own obligations to avoid unfairness regardless of what the courts may require.” Moreover, we do not accept the suggestion of some of plaintiffs’ amici that we recognize their cause of action as a way of goading the Legislature into actions felt to be desirable.

Professor Michelman has written: “We have, in effect, been searching for a useful and satisfying way to identify the ‘evil’ supposedly combatted by the constitutional just compensation provisions, and have now suggested equating it with a capacity of some collective actions to imply that someone may be subjected to immediately disadvantageous or painful treatment for no other apparent reason . . . than that someone else’s claim to satisfaction has been ranked as intrinsically superior to his own. . ..

We should, then, consider carefully the extent to which the ‘fairness’ or utility rationale is already reflected, even if inexplicitly, in the judicial doctrines which presently compose the main corpus of our just compensation lore. My conclusion is that these doctrines do significantly reflect the line of thought which has' been elaborated in these pages. . . .” Michelman, Property, Utility, and Fairness: Comments on the Ethical Foundations of “Just Compensation” Law, supra, 80 Harv.L.Rev. 1165, 1224-1226.
