483 US. 825 (1987)
James and Marilyn Nollan leased with an option to purchase a small bungalow situated on a beachfront lot in Ventura County, California. Their option to buy was conditioned on their promise to demolish the bungalow, which had fallen into disrepair, and replace it with a new structure. In order to do so, they had to obtain a development permit from the California Coastal Commission. The Commission informed the Nollans that it would grant the permit only on the condition that they grant an easement allowing for public access to the beach across their property. The Nollans filed sit it in the superior court, which invalidated the easement condition and ordered that it be stricken from the permit. The California Coastal Commission appealed to the California Court of Appeals, which reversed the superior court. The Nollans appealed to the US. Supreme Court.
Justice Scalia delivered the Opinion of the Court.
... Had California simply required the Nollans to make an easement across their beachfront available to the public on a permanent basis in order to increase public access to the beach, rather than conditioning their permit to rebuild their house on their agreeing to do so, we have no doubt there would have been a taking. To say that the appropriation of a public easement across a landowner's premises does constitute a taking of a property interest but rather (as Justice Brennan contends) "a mere restriction on its use," *** is to use words in a manner that deprives them of all their ordinary meaning. Indeed, one of the principal uses of the eminent domain power is to assure that government be able to require conveyance of such interests, so long as it pays for them. *** Perhaps because the point is so obvious, we have never been confronted with a controversy that required us to rule upon it, but our cases' analysis of the effects of other governmental action lead us to the same conclusion....
Given, then, that requiring uncompensated conveyance of the easement outright would violate the Fourteenth Amendment, the question becomes whether requiring it to be conveyed as a condition for issuing a land-use permit alters the outcome. We have long recognized that land use regulation does not effect a taking if it "substantially advance[s] legitimate state interests" and does not Aden[y] an owner economically viable use of his land." *** Our cases have not elaborated on the standards for determining what constitutes a "legitimate state interest" or what type of connection between the regulation and the state interest satisfies the requirement that the former "substantially advance" the latter. They have made clear, however, that a broad range of governmental purposes and regulations satisfies these requirements. *** The Commission argues that among these permissible purposes are protecting the public's ability to see the beach, assisting the public in overcoming the "psychological barrier" to using the beach created by a developed shorefront, and preventing congestion on the public beaches. We assume, without deciding, that this is so - in which case the Commission unquestionably would be able to deny the Nollans their permit outright if their new house (alone, or by reason of the cumulative impact produced in conjunction with other construction) would substantially impede these purposes, unless the denial would interfere so drastically with the Nollans use of their property as to constitute a taking. ***
The Commission argues that a permit condition that serves the same legitimate police-power purpose as a refusal to issue the permit should not be found to be a taking if the refusal to issue the permit would not constitute a taking. We agree.... Although such a requirement, constituting a permanent grant of continuous access to the property, would have to be considered a taking if it were not attached to a development permit, the Commission's assumed power to forbid construction of the house in order to protect the public's view of the beach must surely include the power to condition construction upon some concession by the owner, even a concession of property rights, that serves the same end. If a prohibition designed to accomplish that purpose would be a legitimate exercise of the police power rather than a taking, it would be strange to conclude that providing the owner an alternative to that prohibition which accomplishes the same purpose is not.
The evident constitutional propriety disappears, however, if the condition substituted for the prohibition utterly fails to further the end advanced as the justification for the prohibition. When that essential nexus is eliminated, the situation becomes the same as if California law forbade shouting fire in a crowded theater, but granted dispensations to those willing to contribute $100 to the state treasury. While a ban on shouting fire can be a core exercise of the State's police power to protect the public safety, and can thus meet even our stringent standards for regulation of speech, adding the unrelated condition alters the purpose to one which, while it may be legitimate, is inadequate to sustain the ban. Therefore, even though, in a sense, requiring a $100 tax contribution in order to shout fire is a lesser restriction on speech than an outright ban, it would not pass constitutional muster. Similarly here, the lack of nexus between the condition and the and the original purpose of the building restriction converts that purpose to something other than what it was. The purpose then becomes, quite simply, the obtaining of an easement to serve some valid governmental purpose, but without payment of compensation. Whatever may be the outer limits of "legitimate state interests" in the takings and land use context, this is not one of them. In short, unless the permit condition serves the same governmental purpose as the development ban, the building restriction is not a valid regulation of land use but "out-and-out plan of extortion." ***
... It is quite impossible to understand how a requirement that people already on the public beaches be able to walk across the Nollans' property reduces any obstacles to viewing the beach created by the new house. It is also impossible to understand how it lowers any "psychological barrier" to using the public beaches, or how it helps to remedy any additional congestion on them caused by the construction of the Nollans' new house. We therefore find that the Commission's imposition of the permit condition cannot be treated as an exercise of its land use power for any of these purposes. Our conclusion on this point is consistent with the approach of every other court that has considered the question, with the exception of the California state courts. ***
Justice Brennan argues that imposition of the access requirement is not irrational. In his version of the Commission's argument, the reason for the requirement is that in its absence, a person looking toward the beach from the road will see a street of residential structures including the Nollans' new home and conclude that there is no public beach nearby. If, however, that person sees people passing and repassing along the dry sand behind the Nollans' home, he will realize that there is a public beach somewhere in the vicinity. The Commission's action, however, was based on the opposite factual finding that the wall of houses completely blocked the view of the beach and that a person looking from the road would not be able to see it at all....
We are left, then, with the Commission's justification for the access requirement unrelated to land use regulation:
"Finally, the Commission notes that there are several existing provisions of pass and repass lateral access benefits already given by past Faria Beach Tract applicants as a result of prior coastal permit decisions. The access required as a condition of this permit is part of a comprehensive program to provide continuous public access along Faria Beach as the lots undergo development or redevelopment." ***
That is simply an expression of the Commission's belief that the public interest will be served by a continuous strip of publicly accessible beach along the coast. The Commission may well be right that it is a good idea, but that does not establish that the Nollans (and other coastal residents) alone can be compelled to contribute to its realization. Rather, California is free to advance its "comprehensive program," if it wishes, by using its power of eminent domain for the "public purpose," see U.S. Const., Amdt. V; but if it wants an easement across the Nollans' property, it must pay for it.
Reversed.
Justice Brennan, with whom Justice Marshall joins, dissenting.
.. .The Court's conclusion that the permit rendition imposed on appellants is unreasonable cannot withstand analysis. First, the Court demands a degree of exactitude that is inconsistent with our standard for reviewing the rationality of a state's exercise of its police power for the welfare of its citizens. Second, even if the nature of the public access condition imposed must be identical to the precise burden on access created by appellants, this requirement is plainly satisfied....
Imposition of the permit condition in this case represents the State's reasonable exercise of its police power. The Coastal Commission has drawn on its expertise to preserve the balance between private development and public access, by requiring that any project that intensifies development on the increasingly crowded California coast must be offset by gains in public access. Under the normal standard for review of the police power, this provision is eminently reasonable. Even accepting the Court's novel insistence on a precise quid pro quo of burdens and benefits, there is a reasonable relationship between the public benefit and the burden created by appellants' development. The movement of development closer to the ocean creates the prospect of encroachment on public tidelands, because of fluctuation in the mean high tide line. The deed restriction ensures that disputes about the boundary between private and public property will not deter the public from exercising its right to have access to the sea.
Furthermore, consideration of the Commission's action under traditional takings analysis underscores the absence of any viable takings claim. The deed restriction permits the public only to pass and repass along a narrow strip of beach, a few feet closer to a seawall at the periphery of appellants' property. Appellants almost surely have enjoyed in increase in the value of their property even with the restriction, because they have been allowed to build a significantly larger new home with garage on their lot...
... State agencies ... require considerable flexibility in responding to private desires for development in a way that guarantees public access to the coast. They should be encouraged to regulate development in the context of the overall balance of competing uses of the shoreline. The Court today precisely the opposite, overruling an eminently reasonable exercise of an expert state agency's judgment, substituting its own narrow view of how this balance should be struck. Its reasoning is hardly suited to the complex reality of natural resource protection in the 20th century. I can only hope that today's decision is an aberration, and that a broader vision ultimately prevails.
I dissent.
Justice Blackmun, dissenting.
... I disagree with the Court's rigid interpretation of the necessary correlation between a burden created by development and a condition imposed pursuant to the State's police power to mitigate that burden. The land-use problems this country faces require creative solutions. These are not advanced by an "eye for an eye" mentality. The close nexus between benefits and burdens that the Court now imposes on permit conditions creates an anomaly in the ordinary requirement that a State's exercise of its police power need be no more than rationally based. In my view, the easement exacted from appellants and the problems their development created are adequately related to the governmental interest in providing public access to the beach. Coastal development by its very nature makes public access to the shore generally more difficult. Appellants' structure is part of that general development and, in particular, it diminishes the public's visual access to the ocean and decreases the public's sense that it may have physical access to the beach. These losses in access can be counteracted, at least in part, by the condition on appellants' construction permitting public passage that ensures access along the beach.
Traditional takings analysis compels the conclusion that there is no taking here. The governmental action is a valid exercise of the police power, and, so far as the record reveals, has a nonexistent economic effect on the value of appellants' property. No investment-backed expectations were diminished. It is significant that the Nollans had notice of the easement before they purchased the property and that public use of the beach had been permitted for decades.
For these reasons, I respectfully, dissent.
