Plaut v. Spendthrift Farm, Inc., 514 U.S. 211 (1995), was a case in which the Supreme Court of the United States held that Congress may not retroactively require federal courts to reopen final judgments.Writing for the Court, Justice Scalia asserted that such action amounted to an unauthorized encroachment by Congress upon the powers of the judiciary and therefore violated the constitutional principle of separation of powers.
