Historical and Revision Notes

Based on title 18, U.S.C., 1940 ed., §§ 452, 454, 567 (Mar. 4, 1909, ch. 321, §§ 273, 275, 330, 35 Stat. 1143, 1152). Section consolidates the punishment provision of section 454 and 567 of title 18, U.S.C., 1940 ed., with section 452 of title 18, U.S.C., 1940 ed. The provision of said section 454 for the death penalty for first degree murder was consolidated with section 567 of said title 18, by adding the words “unless the jury qualifies its verdict by adding thereto ‘without capital punishment’ in which event he shall be sentenced to imprisonment for life”. The punishment for second degree murder was changed and the phrase “for any term of years or for life” was substituted for the words “not less than ten years and may be imprisoned for life”. This change conforms to a uniform policy of omitting the minimum punishment. Said section 567 was not included in section 2031 of this title since the rewritten punishment provision for rape removes the necessity for a qualified verdict. The special maritime and territorial jurisdiction provision was added in view of definitive section 7 of this title.
