These instructions were prepared initially by a Federal Judicial Center committee in 1982 and revised in 1987 by the former Subcommittee on Pattern Jury Instructions of the former Judicial Conference Committee on the Operation of the Jury System. Many courts have since drafted instructions based on the pattern jury instructions.  The Center has neither maintained nor updated these instructions since 1987 and we retain them in our collection for historical interest. They do not necessarily reflect the current state of the law.
