San Remo Hotel, L. P. v. City and County of San Francisco, California

Summary

The Court affirmed the Ninth Circuit, holding that federal courts must apply 28 U.S.C. §1738 and give full faith and credit to state court judgments, so they cannot create an exception for takings claims even when the claim is not ripe under Williamson County. The decision notes that such an exception would require clear congressional intent, which is absent. Justice Rehnquist’s concurring opinion agrees with the judgment but questions the Williamson County state‑litigation requirement.
