Best interests and treatment for mental disorder.

This paper considers the role of the concept of best interests in the treatment of mental disorder. It considers the Mental Capacity Act 2005 where treatment of an incapacitated person's mental disorder is authorized if treatment is in the patient's own best interests. It also examines the Mental Health Act 1983 as amended by the Mental Health Act 2007 where treatment without consent of a detained patient is allowed where necessary for the patient's health or safety or for the protection of others. Under both statutory regimes treatment must be in the best interests of the patient. This paper argues that 'best interests' is open to interpretation to include treatment interventions carried out primarily to protect other people.
