The defendant brought a claim for negligence, alleging that he had been rendered effectively blind as a result of negligent treatment received at the defendant NHS Trust's eye centre. The Queen's Bench Division ruled that the claim could not succeed where, notwithstanding that another expert might have taken a different course, the course adopted by defendant Trust's staff had been one which would have been taken by a responsible body of ophthalmological opinion.
