Court of Appeal of the State of California, First Appellate District, Division Two
The Rule of Quinteros v. Harbor Distributing is that attorneys bear ultimate responsibility for the accuracy and reliability of briefs they file with the court and cannot avoid sanctions by delegating work to contract attorneys who use fabricated AI-generated citations and false quotations, under circumstances where the opposition contained non-existent case citations, fabricated quotations, and blatant misrepresentations of controlling authority.
