Read the decisionOriginal on CourtListener
2,917 written decisions from 2,664 cases in the whole mandamus and agency-delay group, the group's newest decided October 30, 2026. Updated November 3, 2026 at 7:07 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.
These are counts of past written decisions and dockets, not predictions of how any case will be decided. A distribution appears only when at least 5 decisions (or 5 dockets) are behind it; smaller groups are listed, not summarized. How it's counted.

Supreme Court and First 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Supreme Court decisions and the circuit's published decisions listed here bind this court; a circuit disposition marked nonprecedential was not published as precedent and is persuasive only.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

Towns of Wellesley, Concord & Norwood v. FERC, 829 F.2d 275
First Circuit, September 25, 1987. The First Circuit applies the TRAC factors when asked to compel agency action that has been unreasonably delayed.
ImmCite: treatment available, history exists, not clearance

Patel v. Jaddou, 118 F.4th 475
First Circuit, October 16, 2024. Assuming statutory jurisdiction, § 1255(a) does not forbid USCIS from holding adjustment applications until a visa number is immediately available, so no § 706(1) claim lies against the abeyance policy; the Fourth Circuit rejects deciding the merits before the § 1252(a)(2)(B) question.
ImmCite: caution, adverse or limiting treatment found. Reasoning rejected in the Fourth Circuit by Lolakshi Kale v. Angelica Alfonso-Royals, 139 F.4th 329 (2025).
