AI-related case

Carey v. Breakell et al.

U.S. District Court for the District of Utah · Utah · Jul 30, 2026

The district court found multiple case citations in Plaintiff’s counsel’s Opposition could not be located on Westlaw and appeared to be fake (suggesting improper use of AI). The court explained that citation to non-existent opinions undermines filings and may violate Rule 11, but because it was transferring the case to Arizona it left investigation or sanctioning to the receiving judge rather than imposing relief itself.
