Mental capacity and decision-making

This chapter takes the reader through the elements that make up mental capacity and underpin, therefore, decision-making. The provisions of the Mental Capacity Act 2005 (MCA) are considered in some detail, but the laws governing other jurisdictions in the UK are mentioned. It discusses the legal consequences of incapacity, both for the older person concerned and others, are considered and broader principles (e.g. to do with best interests) governing the use of restraint, deprivation of liberty, and support for decision making. Finally, we turn our attention to how international human rights legislation, and the international disability rights movement generally, increasingly shape the legal approach to capacity and decision making in the UK. The chapter ends, therefore, by considering the UN Convention on the Rights of Persons with Disabilities and the compatibility of the MCA with its provisions.
