In Understanding Treatment Without Consent, key contributors examine the work of the UK Mental Health Act Commission (MHAC), which was established to ensure the care and rights of people subjected to the various sections of the 1983 Mental Health Act. Based on a research project funded by the Department of Health, the book also offers a broader exploration of mental health provision in both historical and contemporary contexts, discussing whether mental health reforms have learned the lessons of history. The book builds on earlier work on treatment without consent by providing a more policy-oriented account of mental health law and regulation in the context of health service modernization, discussing contemporary issues facing the MHAC and looking at its future role.
