Background

Robert K. Decker, proceeding pro se, petitioned the Fourth Circuit for a writ of mandamus against the United States District Court for the District of Maryland. Decker alleged that the district court had unduly delayed in ruling on his 28 U.S.C. § 2241 habeas petition, which was pending in the underlying action 1:25-cv-04014-PX. Decker sought an order directing the district court to act on his petition.

The Court’s Holding

A three-judge panel of the Fourth Circuit denied the mandamus petition in an unpublished per curiam opinion. The court found that the record did not reveal undue delay on the part of the district court. Because the mandamus petition lacked an adequate factual foundation—specifically, evidence of the requisite undue delay—the court had no basis to compel district court action.

The panel dispensed with oral argument, concluding that the facts and legal contentions were adequately presented in the written materials and that oral argument would not aid the decisional process.

Key Takeaways

  • A mandamus petition requires a showing that the lower court has unduly delayed action, not merely that a petition remains pending.
  • Petitioners must establish actual, unreasonable delay supported by the record to obtain mandamus relief.
  • Unpublished opinions in the Fourth Circuit are not binding precedent.

Why It Matters

This decision illustrates the Fourth Circuit’s high bar for mandamus review. Mandamus is an extraordinary remedy, and courts will not grant it based solely on the passage of time or a petitioner’s subjective view that action is overdue. The opinion reinforces that district courts retain considerable discretion in managing their dockets, and appellate courts will not interfere absent clear evidence of abuse or unjustifiable delay.
