2,914 written decisions from 2,661 cases in the whole mandamus and agency-delay group, the group's newest decided October 30, 2026. Updated November 3, 2026 at 1:24 a.m. CT; the Passim connector counts the live collection, which can differ by the day's additions and retirements (which total to quote). Coverage: of the 1,606 public decisions since January 1, 2025 that a CourtListener and GovInfo search for mandamus and agency delay finds, Passim holds 1,371 (85%), measured November 3, 2026. Some of what that search finds are not mandamus decisions. Tell us about a decision we're missing.

Supreme Court and D.C. Circuit authority
District decisions bind no one. On the questions this decision raises, the Supreme Court decisions and the circuit's published decisions listed here bind this court; a circuit disposition marked nonprecedential was not published as precedent and is persuasive only.

Norton v. Southern Utah Wilderness Alliance, 542 U.S. 55
Supreme Court, June 14, 2004. Section 706(1) and mandamus reach only a discrete agency action that the agency is legally required to take, so a court cannot compel programmatic improvements or action the law leaves to agency discretion.
ImmCite: treatment available, history exists, not clearance
-
Telecommunications Research & Action Center v. FCC, 750 F.2d 70
D.C. Circuit, October 24, 1984. Whether agency delay is unreasonable turns on six factors: a rule of reason, any statutory timetable, the human welfare interests at stake, the effect of expediting on competing priorities, the interests prejudiced by delay, and no need to find impropriety.
ImmCite: treatment available, history exists, not clearance
-
Mashpee Wampanoag Tribal Council, Inc. v. Norton, 336 F.3d 1094
D.C. Circuit, August 8, 2003. A claim that an agency has unreasonably delayed a matter arises under the APA and § 1331, and the TRAC factors decide whether the delay is unreasonable.
ImmCite: treatment available, history exists, not clearance
-
In re Core Communications, Inc., 531 F.3d 849
D.C. Circuit, July 8, 2008. Mandamus to compel unreasonably delayed agency action is an extraordinary remedy guided by the TRAC factors, granted here after years of unexplained delay.
ImmCite: treatment available, history exists, not clearance
-
Da Costa v. Immigration Investor Program Office, 80 F.4th 330
D.C. Circuit, August 18, 2023. EB-5 petition delays of roughly four years were not unreasonable under TRAC where USCIS adjudicates in a rule-of-reason order and expediting the plaintiffs would only move them ahead of others in the queue.
ImmCite: treatment available, history exists, not clearance
-
American Hospital Ass'n v. Burwell, 812 F.3d 183
D.C. Circuit, February 9, 2016. A delay claim under the Mandamus Act requires a clear duty, a clear right and no adequate alternative remedy, and the TRAC factors then decide whether the delay warrants relief, with a statutory deadline weighing heavily.
ImmCite: treatment available, history exists, not clearance
-
Afghan and Iraqi Allies v. Blinken, 103 F.4th 807
D.C. Circuit, June 7, 2024. TRAC governs visa-processing delay claims in district court, a court that finds unreasonable delay may set adjudication deadlines, and expediting a whole class in queue order is not line-jumping.
ImmCite: unchecked, treatment not confirmed yet, not evidence either way. ImmCite has found no published decision citing this case as of 2026-10-28; it checks for new citing decisions daily. That is not a determination that the case is good law. The citation index lists 49 other decisions citing it, none a Supreme Court, BIA or Attorney General precedent or a published circuit opinion; ImmCite's status does not review them.
