Is your case or statute still good law?
  • Has a Ninth Circuit case been reversed by the U.S. Supreme Court?
  • Has a law from the Revised Code of Washington been declared unconstitutional by the Washington Supreme Court? 
  • Has a Washington Supreme Court case been overruled in a later decision?
  • Have later cases modified or limited the precedential value of a case on which you are relying?


    Use KeyCite to determine the history and status of U.S. and state court cases and statutes.

KeyCite is an online citator, similar to Shepard's. Type in a legal citation (such as 120 S.Ct. 2054; 87 Wash.App. 131; or 42 U.S.C. 1983) and KeyCite will display a history of the case and later cases and other sources that cite to that case.

KeyCite searches citations only. You cannot search by case name, popular names of acts, subjects, or keywords.


KeyCite is available to Westlaw subscribers. For information about access to Westlaw and other online legal research services, see Access to Bloomberg Law, Lexis & Westlaw.
