Why this matter warrants attention
Fabricated: Case Law | Mis-citation/misrepresentation of Page v. Parsons: GBI cited a federal reporter that does not correspond to that Oregon appellate decision and relied on it for a proposition the real Oregon decision does not support. Outcome: Show Cause Order. Lawyer later explained that he had "used Microsoft’s Copilot for its editing functions in an effort to review and improve the draft document by fixing grammar, spelling, and improving badly phrased sentences" - not for legal research.On November 12, 2025, the court resolved the Show Cause proceedings without formal sanctions.
Fabricated: Case Law | Mis-citation/misrepresentation of Page v. Parsons: GBI cited a federal reporter that does not correspond to that Oregon appellate decision and relied on it for a proposition the real Oregon decision does not support. || Fabricated: Case Law | Entirely fabricated opinion and citation attributed to 'Stell v. Cardenas' (case and reporter do not exist; real Case No. 3:21-cv-413 is a different matter). Court found no such opinion at the cited Westlaw number or parties.
Using Copilot for grammar edits still introduces hallucinated citations; ban AI touching any text containing case cites.
