The Federal Rules of Civil Procedure (FRCP) are rules governing civil procedure in United States district (federal) courts, that is, court procedures for civil suits. The FRCP are promulgated by the United States Supreme Court pursuant to the Rules Enabling Act, and then approved by the United States Congress. The Court's modifications to the rules are usually based on recommendations from the Judicial Conference of the United States, the federal judiciary's internal policy-making body. Although federal courts are required to apply the substantive law of the states as rules of decision in cases where state law is in question, the federal courts almost always use the FRCP as their rules of procedure.
(States determine their own rules, which apply in state courts, though most states have adopted rules that are based on the FRCP.)
