A civil dispute in federal court in Mississippi over allegedly unpaid legal fees, brought by attorney Tom Withers of Aberdeen, Mississippi, became a case about AI-assisted legal research. Lawyers for both parties said they had used AI-assisted research and filed documents containing false information. Withers's two lawyers acknowledged they submitted AI-generated material before verifying it, and Aberdeen's lawyers had done the same. Senior U.S. District Judge Sharion Aycock responded with sanctions, pausing the case, removing all four lawyers from the matter and imposing fines, and barring one lawyer from each side from appearing before the court for two years. A law researcher's tracker, cited by press, counts 1,598 matters involving AI-made citations in legal filings.

Notes on gaps

No remediation by the parties is reported; the sanctions are court actions, not remediations. The 1,598-matter count refers to other cases tracked by a researcher, not this incident, and was not used as impact data. Control I7 is marked missing from the lawyers' acknowledged failure to verify before filing; no other controls are stated.
