The Nebraska Supreme Court temporarily suspended Omaha attorney Greg Lake after he submitted a brief in a divorce appeal in which 57 of 63 case references were defective — including fictitious cases and misquoted rulings — generated by an AI tool he initially denied using. Lake later admitted the AI use in an affidavit filed two days before the court ruled, calling it a "grave error of judgment," but the court had already recommended discipline after he misled the justices during oral arguments. The suspension remains in effect until further notice, with a full disciplinary hearing and referee recommendation pending. The case adds to a growing record of courts imposing sanctions on attorneys for undisclosed AI use in filings.
