Castle Rock v. Gonzales, 545 U.S. 748 (2005), is a United States Supreme Court case in which the Court ruled, 7–2, that a town and its police department could not be sued under 42 U.S.C. § 1983 for failing to enforce a restraining order, which had led to the murders of a woman's three children by her estranged husband. The decision has since become infamous and condemned by several human rights groups.
