How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.
(a) Writs of habeas corpus may be granted by the Supreme Court, any justice thereof, the district courts and any circuit judge within their respective jurisdictions. The order of a circuit judge shall be entered in the records of the district court of the district wherein the restraint complained of is had.
(b) The Supreme Court, any justice thereof, and any circuit judge may decline to entertain an application for a writ of habeas corpus and may transfer the application for hearing and determination to the district court having jurisdiction to entertain it.

(5) It is necessary to bring him into court to testify or for trial.

Historical and Revision Notes
1948 Act
Based on title 28, U.S.C., 1940 ed., §§451, 452, 453 (R.S. §§751, 752, 753; Mar. 3, 1911, ch. 231, §291, 36 Stat. 1167; Feb. 13, 1925, ch. 229, §6, 43 Stat. 940).
Section consolidates sections 451, 452 and 453 of title 28, U.S.C., 1940 ed., with changes in phraseology necessary to effect the consolidation.
Words “for the purpose of an inquiry into the cause of restraint of liberty” in section 452 of title 28, U.S.C., 1940 ed., were omitted as merely descriptive of the writ.
Subsection (b) was added to give statutory sanction to orderly and appropriate procedure. A circuit judge who unnecessarily entertains applications which should be addressed to the district court, thereby disqualifies himself to hear such matters on appeal and to that extent limits his usefulness as a judge of the court of appeals. The Supreme Court and Supreme Court Justices should not be burdened with applications for writs cognizable in the district courts.
1949 Act
This section inserts commas in certain parts of the text of subsection (b) of section 2241 of title 28, U.S.C., for the purpose of proper punctuation.
