United States v. Morrison, 529 U.S. 598 (2000), is a U.S. Supreme Court decision that held that parts of the Violence Against Women Act of 1994 were unconstitutional because they exceeded the powers granted to the US Congress under the Commerce Clause and the Fourteenth Amendment's Equal Protection Clause. Along with United States v. Lopez (1995), it was part of a series of Rehnquist Court cases that limited Congress's powers under the Commerce Clause.
