Property owners sometimes allege that a local government has violated the Fifth Amendment’s takings clause, which prohibits the taking of private property “for public use, without just compensation.” But where can plaintiffs bring those claims? In Wednesday’s argument in Knick v. Township of Scott, the Supreme Court revisited a 1985 case that has made it difficult to bring certain takings claims in federal court. In that case, Williamson County Regional Planning Commission v. Hamilton Bank, the court ruled that “if a state provides an adequate procedure for seeking just compensation, the property owner cannot claim a violation of the Just Compensation Clause until it has used the procedure and been denied just compensation.”
