18 U.S.C. § 3731 (CRIMES AND CRIMINAL PROCEDURE)
§ 3731. Appeal by United States
In a criminal case an appeal by the United States shall lie to a court of appeals from a decision, judgment, or order of a district court dismissing an indictment or information or granting a new trial after verdict or judgment, as to any one or more counts, or any part thereof, except that no appeal shall lie where the double jeopardy clause of the United States Constitution prohibits further prosecution.
An appeal by the United States shall lie to a court of appeals from a decision or order of a district court suppressing or excluding evidence or requiring the return of seized property in a criminal proceeding, not made after the defendant has been put in jeopardy and before the verdict or finding on an indictment or information, if the United States attorney certifies to the district court that the appeal is not taken for purpose of delay and that the evidence is a substantial proof of a fact material in the proceeding.
An appeal by the United States shall lie to a court of appeals from a decision or order, entered by a district court of the United States, granting the release of a person charged with or convicted of an offense, or denying a motion for revocation of, or modification of the conditions of, a decision or order granting release.
The appeal in all such cases shall be taken within thirty days after the decision, judgment or order has been rendered and shall be diligently prosecuted.
The provisions of this section shall be liberally construed to effectuate its purposes.

text: Based on title 18, U.S.C., 1940 ed., § 682 (Mar. 2, 1907, ch. 2564, 34 Stat. 1246; Mar. 3, 1911, ch. 231, § 291, 36 Stat. 1167; Jan. 31, 1928, ch. 14, § 1, 45 Stat. 54; May 9, 1942, ch. 295, § 1, 56 Stat. 271).
The word “dismissing” was substituted for “sustaining a motion to dismiss” in two places for conciseness and clarity, there being no difference in effect of a decision of dismissal whether made on motion or by the court sua sponte.
Minor changes were made to conform to Rule 12 of the Federal Rules of Criminal Procedure. The final sentence authorizing promulgation of rules is omitted as redundant.

Such first and second pars. superseded former first eight pars. Pars. one through four had provided for appeal from district courts to Supreme Court from decision or judgment setting aside, or dismissing any indictment or information, or any count thereof and from decision arresting judgment of conviction for insufficiency of indictment or information, where such decision or judgment was based upon invalidity or construction of the statute upon which the indictment or information was founded and for an appeal from decision or judgment sustaining a motion in bar, where defendant had not been put in jeopardy. Pars. five through eight provided for appeal from district courts to a court of appeals where there were no provisions for direct appeal to Supreme Court from decision or judgment setting aside, or dismissing any indictment or information, or any count thereof and from decision arresting a judgment of conviction, and from an order, granting a motion for return of seized property or a motion to suppress evidence, made before trial of a person charged with violation of a Federal law, if the United States attorney certified to the judge who granted the motion that the appeal was not taken for purpose of delay and that the evidence was a substantial proof of the charge pending against the defendant.
