18 U.S. Code § 3231 - District courts
The district courts of the United States shall have original jurisdiction, exclusive of the courts of the States, of all offenses against the laws of the United States.
Nothing in this title shall be held to take away or impair the jurisdiction of the courts of the several States under the laws thereof.
Based on section 588d of title 12, U.S.C., 1940 ed., Banks and Banking; title 18, U.S.C., 1940 ed., §§ 546, 547 (Mar. 4, 1909, ch. 321, §§ 326, 340, 35 Stat. 1151, 1153; Mar. 3, 1911, ch. 231, § 291, 36 Stat. 1167; May 18, 1934, ch. 304, § 4, 48 Stat. 783).
The language of said section 588d of title 12, U.S.C., 1940 ed., which related to bank robbery, or killing or kidnapping as an incident thereto (see section 2113, of this title), and which read “Jurisdiction over any offense defined by sections 588b and 588c of this title shall not be reserved exclusively to courts of the United States” was omitted as adequately covered by this section.
The text of this section was changed by Senate amendment. See Senate Report No. 1620, amendment No. 10, 80th Cong.
