2,996 written decisions from 2,731 cases in the whole mandamus and agency-delay group, the group's newest decided November 12, 2026. Updated November 14, 2026 at 1:17 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 1,617 public decisions since January 1, 2025 that a CourtListener and GovInfo search for mandamus and agency delay finds, Passim holds 1,406 (87%), 1,039 of them in this group, measured November 14, 2026. Some of what that search finds are not mandamus decisions. Tell us about a decision we're missing.

Supreme Court and Second 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Supreme Court decisions and the circuit's published decisions listed here bind this court; a circuit disposition marked nonprecedential was not published as precedent and is persuasive only.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
-
Ajlani v. Chertoff, 545 F.3d 229
Second Circuit, October 7, 2008. A district court may not grant naturalization under § 1447(b) while removal proceedings are pending against the applicant, because § 1429 gives removal priority.
ImmCite: caution, adverse or limiting treatment found. Rejected in the Third Circuit by Gonzalez v. Secretary of Department of HomeLand Security, 678 F.3d 254 (2012).
-
Bustamante v. Napolitano, 582 F.3d 403
Second Circuit, September 28, 2009. Once an applicant files under § 1447(b), the district court has exclusive jurisdiction over the naturalization application until it decides the matter or remands, and USCIS may not act on it meanwhile.
ImmCite: treatment available, history exists, not clearance. ImmCite has read all 7 published decisions citing this case, as of 2026-11-13; none treats it adversely. That describes those decisions; it is not a determination that the case is good law.
