In a California housing dispute against Cushman & Wakefield, plaintiffs submitted a video exhibit purporting to show witness testimony that a judge determined was an AI-generated deepfake, noting the subject’s disjointed voice and fuzzy, emotionless face. Alameda County Superior Court Judge Victoria Kolakowski dismissed the case with prejudice as a terminating sanction after finding the plaintiffs had knowingly submitted fabricated evidence, and later denied a motion for reconsideration. The case is among the first documented instances of a fabricated AI video being presented as authentic evidence in a U.S. courtroom.
