What this means for you
If you put a model anywhere near a legal, medical or financial workflow, this is the failure to design against: a citation that reads correctly and points at nothing. The report names no tool, no cause and no CPS response, so there is nothing to migrate or avoid today.
A legal precedent that does not exist was cited in a high court case, according to court documents reported by the Guardian, which links the citation to an AI search. The reference came from Ravinder Dhillon, a senior crown prosecutor acting for the Crown Prosecution Service, during a dispute over whether a child should be prosecuted for the rape of his younger sister. The Guardian calls the episode a serious failure and says it adds to dozens of AI-related errors in court proceedings. No CPS response is recorded.
