Assessing mental capacity: tensions, values and duties

This is a commentary on two articles on assessing mental capacity in everyday practice and in the case of the suicidal patient. It explores some of the conceptual problems with capacity, including the lack of a ‘right’ answer and the value-laden nature of capacity assessments in suicidal patients. In England and Wales, in addition to the Mental Capacity Act 2005 clinicians must also consider their duty of care as part of the European Convention on Human Rights as enacted in the Human Rights Act 1998.
