This appeal arises from a dispute between Plaintiffs Henry Torromeo and MDR Corporation and Defendant Town of Fremont, New Hampshire over the Town’s delay in issuing certain building permits for property owned by Plaintiffs. Plaintiffs sued in federal court under 42 U.S.C. § 1983, claiming that the Town’s delay constituted both a violation of the Takings Clause of the Fifth Amendment and a breach of the due process and equal protection guarantees of the Fourteenth Amendment. 1 The district court granted the Town’s motion to dismiss under Fed. R.Civ.P. 12(b)(6) because the complaint was barred by the Rooker-Feldman doctrine and res judicata. We affirm.
The case has a somewhat involved factual and procedural history. In the late 1990s, Plaintiffs received approval from the Fremont Planning Board for planned housing subdivisions. Subsequently, however, the Town enacted a growth control ordinance empowering the Board to limit the number of building permits that it would issue for new residential housing. The Board thereafter implemented such a limitation, which resulted in Plaintiffs being denied the needed permits.
Displeased, Plaintiffs sued in New Hampshire Superior Court, challenging the validity of the growth control ordinance and seeking an injunction compelling the Town to issue the building permits. The court granted the injunction because the Town had failed to satisfy a statutory prerequisite before adopting the ordinance. After the New Hampshire Supreme Court affirmed that ruling, the Town issued the permits.
Plaintiffs then filed additional separate suits in the New Hampshire Superior Court, seeking compensation for the temporary taking of their property during the .period in which they were wrongfully denied the permits. Their complaints referenced both the Takings Clause of the Fifth Amendment to the United States Constitu *115 tion and the analogous provision of the New Hampshire Constitution, Part 1, Article 12. In addition, the complaints cited United States Supreme Court authority interpreting the federal Takings Clause. The cases were consolidated.
The superior court ruled that Plaintiffs were entitled to compensation to offset the losses from the wrongly-denied permits. After a trial on damages, the court awarded MDR $71,600 and Torromeo $23,800. The Town appealed to the New Hampshire Supreme Court which reversed.
See Torromeo v. Fremont,
After the state-court judgment became final, Plaintiffs filed the present action. Their complaint claimed that the Town failure to compensate them justly for a taking violated the Fifth Amendment. They also alleged a violation of their substantive due process rights on the ground that the Town’s denial of the building permits was “arbitrary and capricious,” and a violation of their equal protection rights because the Town treated them differently from “other similarly situated property owners.”
The district court dismissed the complaint on two grounds. It first concluded that the complaint had to be dismissed under the
Rooker-Feldman
doctrine because the Plaintiffs’ “federal lawsuit [was] little more than a thinly disguised effort to reverse the New Hampshire Supreme Court’s decision rejecting their claimed entitlement, under the Fifth Amendment, to the damages for the temporary ‘taking’ of their real property.”
Torromeo v. Fremont,
No. 03-481,
We review the district court’s dismissal order de novo.
See Roth v. United States,
After the district court dismissed Plaintiffs’ complaint, the Supreme Court decided
Exxon Mobil Corp. v. Saudi Basic Indus. Corp.,
Under federal law, “a federal court must give to a state-court judgment the same preclusive effect as would be given that judgment under the law of the state in
*116
which the judgment was entered.”
Migra v. Warren City Sch. Dist. Bd. of Ed.,
In New Hampshire, “the essence of the doctrine of res judicata is that a final judgment by a court of competent jurisdiction is conclusive upon the parties in a subsequent litigation involving the same cause of action.”
In re Juvenile,
At first blush, this case appears to fall squarely within New Hampshire’s res judi-cata rules. The parties to the federal action and the state actions were identical. The same cause of action was before the federal court as was before the state court because both suits sought compensation for harm caused by the Town’s wrongful denial of the permits. And the New Hampshire court entered final judgments on the merits of Plaintiffs’ state-court actions.
There is, however, a complication. In 1985, the United States Supreme Court held that a takings claim under the Fifth Amendment is not ripe until the plaintiff has sought compensation through available state procedures.
See Williamson County Reg’l Planning Comm’n v. Hamilton Bank,
Invoking
Blue Jay Realty,
Plaintiffs argue that res judicata does not bar their federal-court action because (1) their federal claims were not litigated in the state-court action and (2) they were not required to raise these claims in the state-court action because they were not ripe.
See In re Iannochino,
But Plaintiffs’ argument fails because the federal takings claim
was
actually litigated to a final judgment on the merits in the state court. As noted above, Plaintiffs’ state-court complaints identified the Takings Clause of the Fifth Amendment to the United States Constitution as a basis for the cause of action. The complaints also cited
First English Evangelical Lutheran Church v. Los Angeles County,
We turn now to the Plaintiffs substantive due process and equal protection claims. Whether res judicata bars these claims presents a somewhat closer question. These additional federal-law theories were not litigated in the state-court action, and there is a plausible argument that they are not res judicata because they could not have been litigated in that action under
Blue Jay Realty. See Restatement of Judgments (Second), supra.
On the other hand because, as just explained,
*118
Plaintiffs ignored the
Blue Jay Realty
rule by litigating their takings claim in the state-court action, one could argue that the due process and equal protection claims should have been raised along with the takings claim. In any event, we need not decide how New Hampshire’s res judicata law would apply to this unique situation because the due process and equal protection claims fail as a matter of law.
See Carroll v. Xerox Corp.,
We begin with the substantive due process claim. We recently explained the limits on substantive due process claims arising from land-use disputes:
This Court has repeatedly held that rejections of development projects and refusals to issue building permits do not ordinarily implicate substantive due process. Even where state officials have allegedly violated state law or administrative procedures, such violations do not ordinarily rise to the level of a constitutional deprivation. The doctrine of substantive due process does not protect individuals from all governmental actions that infringe liberty or injure property in violation of some law. Rather, substantive due process prevents governmental power from being used for purposes of oppression, or abuse of government power that shocks the conscience, or action that is legally irrational in that it is not sufficiently keyed to any legitimate state interest. Although we have the left door slightly ajar for federal relief in truly horrendous situations, the threshold for establishing the requisite abuse of government power is a high one indeed.
SFW Arecibo Ltd. v. Rodríguez,
In
Arecibo,
real estate developers sued after a state planning board incorrectly determined that their building permit had expired.
Id.
at 137. When suit was filed, the state court had already determined that the permit had been wrongly revoked.
Id.
at 138. We affirmed the dismissal of the substantive due process claim because the complaint stated “[i]n its strongest form ... that the [planning board made an erroneous decision in violation of state law,” which is insufficient to establish a substantive due process violation.
Id.
at 141. So too here. Plaintiffs allege that the Town violated substantive due process by enacting the growth control ordinance without following the procedures mandated by New Hampshire law. But, as in
Arecibo,
the claim is only that the Town’s violation of state law caused Plaintiffs harm. This is not enough.
See id.
at 141;
see also Licari v. Ferruzzi,
The equal protection claim fares no better. Plaintiffs contend that they stated a viable equal protection claim by pleading that, in denying the permits, the Town treated them differently from other “similarly situated property owners.” But only in “extreme circumstances” will a land-use dispute give rise to an equal protection claim.
Arecibo,
Affirmed.
Notes
. The Takings Clause of the Fifth Amendment applies to the states through the Fourteenth Amendment.
See Dolan v. Tigard,
. Last term, the Supreme Court decided
San Remo Hotel, L.P. v. San Francisco,
— U.S. -,
. Plaintiffs point to the fact that the New Hampshire Supreme Court cited only cases interpreting the New Hampshire Constitution as evidence that the litigation did not involve a federal takings claim.
See
Torromeo,
. Plaintiffs also assert that, even if the elements of res judicata are satisfied, we should permit the Fifth Amendment claim to proceed because New Hampshire law imbues courts with discretion to decline to apply res judica-ta. We have not found New Hampshire authority to this effect. The most that can be said is that New Hampshire applies res judi-cata on a "case-by-case basis."
