Why this matter is tracked
In a personal injury action, the Superior Court of California issued a trial order noting that the Plaintiff's opposition papers contained unverified citations to non-existent case law, specifically 'Fairchild v. Park County' and 'Corgain v. Kmart Corp.' The court explicitly stated in an editor's note that these citations were likely generated by AI tools used by counsel and were not attributable to the court. While the court denied the defendants' motion for summary judgment on substantive grounds regarding premises liability and negligence, it included a formal warning regarding the submission of these fabricated authorities. The court preserved the unverified citations in the official record but noted their lack of validity.
