Historical Note

The Supreme Court prescribes rules of criminal procedure for the district courts pursuant to section 2072 of Title 28, United States Code, as enacted by Title IV “Rules Enabling Act” of Pub. L. 100–702 (approved November 19, 1988, 102 Stat. 4648), effective December 1, 1988. Pursuant to section 2074 of Title 28, the Supreme Court transmits to Congress (not later than May 1 of the year in which a rule prescribed under section 2072 is to become effective) a copy of the proposed rule. The rule takes effect no earlier than December 1 of the year in which the rule is transmitted unless otherwise provided by law.

Prior to enactment of Pub. L. 100–702, the Supreme Court promulgated rules of criminal procedure for the district courts pursuant to two sections of Title 18, United States Code. Section 3771 authorized the Court to prescribe rules for all criminal proceedings prior to and including verdict, or finding of guilty or not guilty by the court, or plea of guilty. Section 3772 empowered the Court to prescribe rules with respect to all proceedings after verdict or finding of guilty by the court, or plea of guilty.

By act of June 29, 1940, ch. 445, 54 Stat. 688 (subsequently 18 United States Code, § 3771), the Supreme Court was authorized to prescribe general rules of criminal procedure prior to and including verdict, finding of guilty or not guilty by the court, or plea of guilty, in criminal proceedings. The rules, and subsequent amendments, were not to take effect until (1) they had been first reported to Congress by the Attorney General at the beginning of a regular session and (2) after the close of that session.

Under a 1949 amendment to 18 U.S.C., § 3771, the Chief Justice of the United States, instead of the Attorney General, reported the rules to Congress. In 1950, section 3771 was further amended so that amendments to the rules could be reported to Congress not later than May 1 each year and become effective 90 days after being reported. Effective December 1, 1988, section 3771 was repealed and supplanted by new sections 2072 and 2074 of Title 28, United States Code, see first paragraph of Historical Note above. The original rules pursuant to act of June 30, 1940, were adopted by order of the Court on December 26, 1944, transmitted to Congress by the Attorney General on January 3, 1945, and became effective March 21, 1946 (327 U.S. 821; Cong.

Rec., vol. 119, pt. 3, p. 3247, Exec. Comm. 359; H. Doc. 93–46). Although these amendments were to have become effective July 1, 1973, Public Law 93–12 (approved March 30, 1973, 87 Stat. 9) provided that the proposed amendments “shall have no force or effect except to the extent, and with such amendments, as they may be expressly approved by Act of Congress.” Section 3 of Public Law 93–595 (approved January 2, 1975, 88 Stat. 1949) approved the amendments proposed by the Court, to be effective July 1, 1975. The amendments affected Rules 26, 26.1, and 28.

In its order dated April 22, 1974, the Court proposed additional amendments which were transmitted to Congress by the Chief Justice on the same day.

Section 404(a) of Public Law 98–473 (98 Stat. 2067) amended Rule 12.2(a). Section 404(b) to (d) of Public Law 98–473 would have amended Rule 12.2(b) to (d), but the amendments by section 404(b) and (d) were repealed by section 11(b) of Public Law 98–596 (approved October 30, 1984, 98 Stat. 3138) and the amendment by section 404(c) of Public Law 98–473 could not be executed because it directed the deletion of language not found in the text of the Rule [that defect being cured by section 11(a) of Public Law 98–596, which amended Rule 12.2(c) and (d)].
