In England and Wales, the term Claimant replaced Plaintiff after the Civil Procedure Rules 1998 came into force on 26 April 1999. In Scottish law a plaintiff is referred to as a pursuer and a defendant as a defender. Complainant may also denote the complaining witness in a criminal proceeding. In Hong Kong, Canada and the United States, as well as in both Northern Ireland and the Republic of Ireland, the legal term plaintiff is still in use.
