Accuracy update — reviewed August 7, 2026. Mandamus is not a demand that automatically compels a ruling. It is a discretionary, extraordinary remedy requiring a precise showing under the correct statute and court rules.
Different mandamus authorities
28 U.S.C. § 1361 gives federal district courts jurisdiction over actions seeking to compel a federal officer or employee to perform a duty owed to the plaintiff. It does not authorize a federal district court to direct state judges or state officers.
28 U.S.C. § 1651, the All Writs Act, allows federal courts to issue writs in aid of their existing jurisdiction. A petition asking a federal court of appeals to direct a district court is governed procedurally by Federal Rule of Appellate Procedure 21.
The demanding standard
Cheney v. U.S. District Court, 542 U.S. 367 (2004), describes three central requirements: no other adequate means to obtain relief, a clear and indisputable right, and a conclusion that the writ is appropriate under the circumstances. Mandamus is not a substitute for appeal or a device for controlling a judge’s discretionary decision.
Delay petitions
Appellate courts can act when delay becomes extreme, but there is no universal number of days that compels mandamus. The court may consider how long a matter has been fully submitted, complexity, docket activity, responsibility for delay, urgency, prejudice, and whether reasonable status requests were made.
28 U.S.C. § 1657 provides priority for certain federal actions and for good cause. It does not itself guarantee a decision by a particular date or eliminate the mandamus standard.
Build the petition from the docket
- Identify the exact nondiscretionary duty or pending matter.
- Provide a dated chronology with docket citations.
- Explain why ordinary motions or appeal are inadequate.
- Describe concrete prejudice caused by delay.
- Request the narrowest relief necessary—often a ruling, not a particular outcome.
- Follow formatting, service, appendix, and filing requirements.
