Legal Principles
Informed consent; patient autonomy is paramount. Doctors must take reasonable care to ensure patients are aware of material risks and reasonable alternatives.
Montgomery v Lanarkshire [2015] UKSC 11
Negligence test for professionals (Bolam test): A professional is not negligent if acting in accordance with a practice accepted as proper by a responsible body of opinion, even if another body holds a contrary view.
Bolam v Friern Hospital Management Committee [1957] 1 W.L.R. 582
Causation ('but for' test): The fault is the cause of the damage only if the damage would not have happened but for that fault.
Barnett v Chelsea and Kensington Hospital Management Committee [1969] 1 QB 428
Thirteen axioms of fact-finding, including burden of proof, reliance on evidence, iterative analysis, limitations of memory, and assessment of credibility.
Various cases cited in section III.d
Outcomes
Claim dismissed.
The claimant failed to prove both that she would have chosen the alternative procedure if properly informed (Issue 6) and that the Staphylococcus epidermidis infection causing the amputation was present before the January 28 procedure (Issue 7). While the surgeon was found negligent in his informed consent process, this negligence did not cause the loss.
