Negligence – Causation. The claimant suffered a brain tumour which was removed in due course. He brought a case in negligence against the relevant professionals who had first seen him in the Accident and Emergency Department as no one assessed him as warranting an immediate CT scan until mid August 2010, some seven months after he first presented. The Queen's Bench Division failed to find a breach of duty of care in regard to any of the medical professionals in charge of the claimant bearing in mind the pressures and manner of working of an A & E department.
