Medical practitioner – Negligence. Judgment had been entered for the claimant against the defendant surgeon for damages for negligence on the part of the defendant in a surgical procedure performed by him upon the claimant's late wife, following which, she had suffered kidney failure. The Court of Appeal, Civil Division, in dismissing the defendant's appeal, held, inter alia, that the judge had been entitled to have fastened upon those aspects of the evidence which he had found to have been reliable pointers to what had actually occurred during the procedure, without trawling through every issue, side issue or speculation that arose on the evidence or in argument.
