“If an Expert, a lawyer, an accountant, an engineer, a doctor produce inaccurate or unreliable opinions or use hallucinatory references, they are likely to be liable in negligence, whether they’ve used AI or not.” Sir Geoffrey Vos KG, Master of the Rolls

The Claimant suffered serious injuries in a road traffic accident after the Defendant, who was driving out of a side road, collided with the Claimant’s motorbike. Despite being aware of surveillance evidence before preparing his last report, the Claimant’s orthopaedic expert did not reveal his true opinions on the Claimant’s malingering until cross-examination.
