2009
Written decisions in the mandamus and agency-delay group decided in 2009, and agency-delay suits filed in 2009.
2,948 written decisions from 2,691 cases in the whole mandamus and agency-delay group, the group's newest decided November 10, 2026. Updated November 11, 2026 at 1:21 p.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 1,632 public decisions since January 1, 2025 that a CourtListener and GovInfo search for mandamus and agency delay finds, Passim holds 1,398 (86%), measured November 11, 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.

Each case counts once in these outcome counts, by its latest decision here. A motion to dismiss denied and a later judgment for the government count as the judgment. How decisions are grouped into cases.
Disposition, by case
Months from the application to the suit
32.5 months at the median; half fall between 25.1 and 50.3. 14 cases state it.
7 of these are section 1447(b) naturalization suits, whose months run from the application; the statute's 120 days run from the interview, which these figures do not measure.
Months from the application to the court's decision, or to the agency's action where it acted first
36.4 months at the median; half fall between 12.8 and 62.8. 17 decisions state it.
In 7 of these the agency acted before the decision, so the months run to that action, where the delay ended.
Leaves out the 3 decisions holding that the agency had acted where no reading dates that action: their months to the decision are not a delay.

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 filed in 2009. Check a delay counts fewer: a court's suits of the last three years against the form's agency.
0 dockets: fewer than 5, so no distribution is shown.
