CPS Prosecutor Cites Fake 2024 Case in Child Rape Dispute, Lifting UK AI Error Tally to 101
1 articles · Updated · The Guardian · Nov 3
Summary
Ravinder Dhillon, a senior CPS prosecutor, relied on a nonexistent case in High Court arguments backing the prosecution of an 11-year-old boy accused of raping his seven-year-old sister.
Court documents show the false citation came from an AI-generated internet search summary; Dhillon admitted the error in October after citing a fabricated 2024 authority instead of a real ruling from 15 years earlier.
Two senior judges called her explanation unsatisfactory, while legal academic Brian Flanagan said using a made-up authority for a state prosecution was a serious failure that undermines trust in legal sources.
The High Court said the fictitious case did not affect the outcome of the boy's challenge, and his youth court trial is due later this week.
The incident is only the second known CPS case involving likely AI-fuelled false authorities and takes a UK tracker of confirmed, suspected and disputed AI-related legal errors to 101.
Will UK prosecutors face contempt charges after repeatedly submitting fake AI-generated court rulings in highly sensitive trials?
Could a prosecutor's reliance on a hallucinated AI legal case derail justice for an 11-year-old boy facing serious charges?
If advanced AI models still fail to detect fabricated legal citations, should courts ban AI research tools entirely?
The November 2026 CPS Fake Precedent Incident: AI Hallucinations, Legal Ethics, and 101 UK Court Errors
Overview
In November 2026, a senior CPS prosecutor submitted a fake legal precedent to the High Court while prosecuting an 11-year-old boy, after AI-generated research from a web search produced a non-existent case. CPS safeguards failed to catch the error, and judges criticized the explanation as unsatisfactory. Although the High Court found the mistake did not affect the case outcome, the incident triggered an urgent CPS review and new rules requiring citations only from trusted sources. This event followed earlier AI-related citation errors and highlighted growing risks as both legal professionals and unrepresented litigants increasingly rely on generative AI, prompting calls for stricter oversight and reforms.
