Illinois v. Gates

Case Date: 05/06/1983

Illinois v. Gates, 462 U.S. 213 (1983), is a Fourth Amendment case. Gates overruled Aguilar v. Texas, 378 U.S. 108 (1964) and Spinelli v. United States, 393 U.S. 410 (1969), thereby replacing the Aguilar–Spinelli test for probable cause with the "totality of the circumstances" test.
