Abstract
Canada has recently published a new Clinical Practice Guideline on the diagnosis and management of brain death. It states that consent is not necessary to carry out the interventions required to make the diagnosis. A supporting article not only sets out the arguments for this but also contends that ‘UK laws similarly carve out an exception, excusing clinicians from a prima facie duty to get consent’. This is supplemented by the claim that recent court decisions in the UK similarly confirm that consent is not required, referencing two judgements in _Battersbee_. We disagree with the authors’ interpretation of the law on consent in the UK and argue that there is nothing in _Battersbee_ to support the conclusion that consent to testing is not necessary. Where there is a disagreement about testing for brain death in the UK, court authorisation is required.
