Courts / Tenth Circuit
District of Colorado
Written decisions in the mandamus and agency-delay group from this court, and the agency-delay suits filed there.
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.

How agency-delay suits ended
Most suits end without a written decision: the agency acts and the parties dismiss. These counts come from the docket record (the federal courts' Integrated Database and CourtListener) and count every mandamus, APA and section 1447(b) suit against any immigration agency, whatever year it was filed. Check a delay counts fewer: a court's suits of the last three years against the form's agency.

How the ended suits ended
- Ended once the agency actedThe plaintiff dismissed, the parties stipulated to dismissal, or the court dismissed as moot: how suits end once the agency decides. The docket rarely says why, or whether the agency approved or denied.336
- Ended, outcome not recordedThe record shows the suit ended but not how.44
- Dismissed on jurisdiction or the meritsDismissed for want of jurisdiction or on the TRAC factors, or judgment for the government.20
- Dismissed, ground not recordedThe court dismissed and the record gives no ground: it can be a dismissal as moot after the agency acted, for want of prosecution, or a loss.11
- Remanded to the agencySent back to the agency, usually a naturalization case under section 1447(b).9
- TransferredMoved to another district court.4
The record gives no reason for 10% of the suits that ended.
