§3144 Release or Detention of a Material Witness

Title 18 › PART II — CRIMINAL PROCEDURE › CHAPTER 207 — RELEASE AND DETENTION PENDING JUDICIAL PROCEEDINGS › § 3144

Last updated Aug 21, 2026|Official source

Summary

A judge may order the arrest of someone when an affidavit says their testimony is needed and it may be impractical to get them by subpoena. The judge then handles that person under section 3142. A witness cannot be kept just because they cannot meet release conditions if a deposition will secure the testimony and more detention is not needed. Release can be delayed for a reasonable time so the deposition can be taken under the Federal Rules of Criminal Procedure.

Title 18, §3144

Crimes and Criminal Procedure, Source: USLM XML via OLRC

If it appears from an affidavit filed by a party that the testimony of a person is material in a criminal proceeding, and if it is shown that it may become impracticable to secure the presence of the person by subpoena, a judicial officer may order the arrest of the person and treat the person in accordance with the provisions of section 3142 of this title. No material witness may be detained because of inability to comply with any condition of release if the testimony of such witness can adequately be secured by deposition, and if further detention is not necessary to prevent a failure of justice. Release of a material witness may be delayed for a reasonable period of time until the deposition of the witness can be taken pursuant to the Federal Rules of Criminal Procedure.
