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Court decisions and the circuit's published decisions listed here bind this court; a circuit disposition marked nonprecedential was not published as precedent and is persuasive only.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

Independence Mining Co. v. Babbitt, 105 F.3d 502
Ninth Circuit, January 23, 1997. Mandamus and APA § 706(1) claims to compel delayed agency action are analyzed alike under the TRAC factors.
ImmCite: treatment available, history exists, not clearance

Vaz v. Neal, 33 F.4th 1131
Ninth Circuit, May 9, 2022. Section 706(1) compels only a clear, mandatory and discrete duty that has been unreasonably delayed under TRAC, and the APA's prerequisites go to the merits while § 1331 supplies jurisdiction.
ImmCite: unchecked, treatment not confirmed yet, not evidence either way. ImmCite has found no published decision citing this case as of 2026-11-03; it checks for new citing decisions daily. That is not a determination that the case is good law. The citation index lists 144 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.
