What the court wrote
Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.
In reviewing the Plaintiff's filings, the Court identified four citations offered by Plaintiff in its Reply that do not exist. At the hearing on the Motion, the Court asked Mr. Charnley about the nonexistent citations and whether he or anyone at his firm used generative AI to assist with drafting its papers. Mr. Charnley stated that he wrote the brief, that he did not use generative AI in preparing the brief, and that he was not aware that anyone in his firm used such technology. ... The hallucinated citations wasted the Court's limited resources.
