This article seeks to discuss informed consent in English law. The attitudes on informed consent have shifted to a more patient-centred approach following Montgomery v Lanarkshire Health Board [2015] UKSC 11, [2015] AC 1430, as opposed to the long-standing Bolam decision where clinical judgment was more widely accepted. Thus, following on from the decision in Montgomery a patient is required to know about material risks regarding the proposed treatment and not what the doctor thinks would be the best practice as has been the long-standing consensus since Bolam was decided back in 1957 with subsequent cases following suit. The Montgomery principle has allowed more transparency in the patient-doctor relationship, allowing for a discussion between the doctor and the patient to be the central focus. The outcome of Montgomery was a much needed change in healthcare because prior to this it could be seen that patients were having decisions made on their behalf, and if they had been informed accordingly regarding the risks involved may have decided not to go ahead with the procedure. In the case of Diamond v Royal Devon & Exeter NHS Foundation Trust [2019] EWCA Civ 585 the case highlights the issue of causation in medical negligence action if a doctor does not warn of risks and advise treatment alternatives this would not result in a claim for damages because the patient in this case as was held would have gone ahead with the mesh repair in any case, and thus failing to establish causation could result in no remedy as it did in Diamond. Furthermore, the recent case of McCulloch and others v Forth Valley Health Board [2023] UKSC 26 adds a bit of salt to the wounds of those who had thought or believed that Montgomery had already clarified the position regarding disclosure of alternative treatments to a patient, and to our dismay to learn of that once again English courts have ruled in favour of 'Bolam'.
