Following the Mental Capacity Act (MCA) becoming law in 2005, and prior to its coming into force in 2007, there was a sustained effort to train support staff in the many social care settings where this new law was applicable. This training drive was necessary because, prior to the MCA, mental capacity law had evolved in the courts through consideration of a small number of cases that concerned serious medical treatments. These included the withdrawal of artificial nutrition and hydration (Airedale NHS Trust v. Bland [1993]), blood transfusion (Re T [1993]), tissue donation (Re Y [1997]) and the provision of experimental medication for terminal illness (Simms v. Simms and another (2003)). In line with the Law Commission’s recommendations, the MCA extended the application of the law to ‘all acts in connection with care or treatment’ (MCA, Section 5), meaning that, overnight, social care settings and informal family care environments immediately fell within the scope of the legislation.
