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 filed in 2010. 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.
