Definitions and criteria: The 2007 amendments to the Mental Health Act 1983

Abstract

This article deals with the provisions for the lawful detention and compulsory treatment of patients in England and Wales. The 2007 amendments to the Mental Health Act 1983 redefine 'mental disorder' and 'medical treatment' and remove the classifications required for longer-term detention, abolishing the so-called 'treatability test' and introducing a new appropriate-treatment test. 'Learning disability' is brought within the definition of mental disorder but only if 'associated with abnormally aggressive or seriously irresponsible conduct'. The exclusion for promiscuity, other immoral conduct or sexual deviancy is repealed; the exclusion for dependence on alcohol and drugs is retained. The revised definition of 'medical treatment' includes psychological treatment and removes the requirement that treatment is under medical supervision. The basic structure of the 1983 Act is retained. Use of the powers is discretionary. The principles of the Mental Capacity Act 2005 are imported into the decision-making framework through the wording of the Mental Health Act Code of Practice.
