The AI Sanctions Case Tracker

Every U.S. case we've verified where a court sanctioned, disciplined, or called to account a lawyer over AI use, written from the court record: what happened, what it cost, and how it could have been avoided. Search by case, attorney, court, or sanction.

What this tracker can and can't show. This page lists the U.S. AI-sanctions cases we've documented from court orders and public records. We find them through court-document services, news coverage, legal writing, social media, and tips from readers, so the list carries a reporting bias: it holds the cases that surfaced. It's a documented floor, not a census. Cases resolved without a public order, under seal, handled quietly, or in courts whose decisions never reach public databases won't appear here, and no public list, ours included, can count them. If you know of a case we're missing, send it through the tip form. It's one way to help close the gap, and every addition is verified against the court record before it's posted.

175 cases tracked · 112 in federal courts · 63 in state courts, agencies, and boards · 18 graded for how the lawyer responded · 20 entries involve a verified repeat offender
