Why this matter is tracked

In a service-and-default dispute, the District of Utah denied without prejudice a defendant's motion to strike the pro se plaintiff's opposition, which the defendant alleged was generated by AI and contained hallucinated case quotations. The court held that Federal Rule of Civil Procedure 12(f) does not authorize motions to strike motions or memoranda. While the court denied the motion to strike, it issued an express warning to the plaintiff regarding the alleged use of AI-hallucinated quotations and cautioned the plaintiff to refrain from improper AI use. The court noted that any potential sanctions for this conduct could be addressed through a separate Rule 11 motion for sanctions previously served by the defendant.
