Two important exceptions to exclusionary rules under the federal constitution were adopted by the United States Supreme Court within a month of each other in 1984: (1) the inevitable discovery exception in Nix v. Williams, 467 U.S. 431 (1984), and (2) the independent source exception in Segura v. United States, 468 U.S. 796 (1984); see also the later case of Murray v. United States, 487 U.S. 533 (1988). These two exceptions continue to be litigated. This post will discuss the inevitable discovery exception, and my next post will discuss the independent source exception.
