The Court overruled the rule that forced property owners to seek compensation in state court before bringing federal takings claims. A takings plaintiff may go to federal court once the government takes property without paying just compensation.
Scott Township adopted an ordinance requiring cemeteries to be open to the public during daylight hours. Knick challenged the ordinance, but lower federal courts dismissed her takings claim under Williamson County because she had not first pursued compensation in state court.
Must a property owner seek just compensation in state court before bringing a federal Takings Clause claim under Section 1983?
A property owner has a Fifth Amendment takings claim under 42 U.S.C. 1983 when the government takes property without paying just compensation, and may bring that federal claim in federal court at that time. The Court overruled Williamson County's state-litigation requirement.
How the justices lined up in this decision.
Knick opened federal court doors for many property owners bringing Takings Clause claims against state and local governments. It did not decide whether Scott Township's ordinance actually took Knick's property; it decided when and where a federal takings claim may be filed.
Chief Justice Roberts wrote for a five-justice majority joined by Justices Thomas, Alito, Gorsuch, and Kavanaugh. Justice Thomas concurred. Justice Kagan dissented, joined by Justices Ginsburg, Breyer, and Sotomayor.
