Government counsel / Tenth Circuit

District of New Mexico

The attorneys who appeared for the government in this court's agency-delay suits, read from each suit's attorneys of record. It is a record of who has appeared, not the office's staff list.

Read from the attorneys of record of 45 of the 118 agency-delay suits in the docket record for this court; 13 of them name government counsel. Only the 45 suits with a public docket on CourtListener can be read, and a suit names no government counsel until an attorney appears and that public copy is refreshed afterwards, so older suits, recent suits and quiet districts are thin. Updated November 14, 2026 at 1:17 a.m. CT. How this list is made.

Suits counts the agency-delay suits in the docket record in which the attorney is counsel of record; the past-year count runs back one year from the newest suit in the record. Some dockets name an office in an attorney's place, usually before a suit is assigned ("AUSA - Chicago"); those are listed last, marked as office entries, with the office's own mailbox. Telephone numbers and email addresses are the ones printed on the public docket of the attorney's latest suit; confirm them on that docket before relying on them. An attorney who has moved on stays listed, and the date of the latest suit shows how current an entry is. Nothing here says how any attorney's suits ended. Tell us about a correction.
