In August 2000, the Judicial Conference’s Committee on Rules of Practice and Procedure published—for public comment—proposed amendments to the entire set of Federal Rules of Criminal Procedure. The proposals mark the culmination of a two-year project to “restyle” the rules—to modernize and reorganize and to make them internally consistent in format and style. Not since the rules were first promulgated in 1946 has there been such a significant change in the structure, format, and substance. This article first addresses the rule-making process for the Federal Rules of Criminal Procedure, and then examines the restyling process. Finally, it notes several of the amendments that could result in significant changes to the practice of criminal law.
