CPS Prosecutor Cites AI-Hallucinated Case to High Court in Alleged Child Rape Proceeding
A senior Crown Prosecution Service prosecutor cited a nonexistent legal precedent before the High Court in a case involving an alleged child rape, after the case was generated by an AI search tool. The phantom authority adds to a growing list of AI hallucination errors recorded in English court proceedings. The incident has prompted fresh concern about prosecutors and litigants relying on AI-generated research without adequate verification before citing authorities to the court.
Why this matters
A Crown prosecutor citing a fabricated authority to the High Court in criminal proceedings is a significant professional conduct event, not merely a technology mishap. It signals that AI hallucination risk has reached the most serious tier of English litigation. The episode intensifies pressure on the CPS and the Bar to implement mandatory verification protocols before AI-sourced authorities are placed before a court. Coming alongside dozens of similar reported errors, it is likely to accelerate judicial and regulatory scrutiny of AI use in legal practice.
On the Ground
Professional discipline and regulatory work is immediately activated: Bar Standards Board and SRA investigations into individual conduct, and potential CPS internal review. Criminal defence teams may seek to challenge proceedings where AI-generated errors infected prosecution submissions. Trainees should expect to draft verification checklists and research notes on existing court guidance on AI use, and to track any formal judicial reaction in this and related cases.
