Informed consent and the law--an English legal perspective.

'Informed consent' is a widely used term, but its application in a legal perspective can be varied. American and Commonwealth jurisdictions have developed a 'patient-based' true informed consent approach, whereas in the English legal system a 'doctor-based' approach has traditionally been applied in relation to disclosure of risk. This article will seek to compare these approaches and give a brief overview of some of the key legal rulings which have shaped the requirement of consent. The decision in the English case of Chester vs. Afshar is considered as showing the significance the court attached to the principle of autonomy and using ethical and policy considerations to depart from established principles of English law relating to consent to treatment and disclosure of risk. This review is intended as general information and not as legal advice which should be sought from defence organisation and specialist health care lawyers.
