§3143 Release or detention of a defendant pending sentence or appeal

Title 18 › Part PART II— - CRIMINAL PROCEDURE › Chapter CHAPTER 207— - RELEASE AND DETENTION PENDING JUDICIAL PROCEEDINGS › § 3143

Last updated Apr 6, 2026|Official source

Summary

A judge must keep a person in custody after a guilty verdict while the judge waits to give or carry out a sentence. The judge can only let the person go if the judge finds, by strong proof, that the person is not likely to run away or hurt anyone if released under section 3142(b) or (c). If the sentencing rules do not call for prison, this custody rule does not apply. For certain serious crimes listed in 3142(f)(1)(A)–(C), the judge must keep the person detained unless two things happen: there is a good chance a new trial or acquittal will be granted or the government asks for no prison, and the judge also finds by strong proof the person is not likely to flee or be dangerous. If a person is already sentenced to prison and appeals, the judge must detain them unless the judge finds they are not likely to flee or be dangerous and the appeal raises a serious question likely to change the result. If the United States appeals under 3731 or 3742, the law gives special rules that the judge must follow.

(a)(1)Except as provided in paragraph (2), the judicial officer shall order that a person who has been found guilty of an offense and who is awaiting imposition or execution of sentence, other than a person for whom the applicable guideline promulgated pursuant to 28 U.S.C. 994 does not recommend a term of imprisonment, be detained, unless the judicial officer finds by clear and convincing evidence that the person is not likely to flee or pose a danger to the safety of any other person or the community if released under section 3142(b) or (c). If the judicial officer makes such a finding, such judicial officer shall order the release of the person in accordance with section 3142(b) or (c).

(B)that the appeal is not for the purpose of delay and raises a substantial question of law or fact likely to result in—
(i)reversal,
(ii)an order for a new trial,
(iii)a sentence that does not include a term of imprisonment, or
(iv)a reduced sentence to a term of imprisonment less than the total of the time already served plus the expected duration of the appeal process.

(1)if the person has been sentenced to a term of imprisonment, order that person detained; and
(2)in any other circumstance, release or detain the person under section 3142.
