The law relating to the mental health care of children and young people aged under 18 (‘adolescents’) is renowned for its complexity. This is unsurprising given that in relation to admission to hospital and treatment for mental disorder, it raises issues of uncertainty such as the limits of the decision-making powers as between parents and their children and the developing law on deprivation of liberty. More widely, the provision of mental health services for this age group involves a range of differing agencies and engages a raft of legislation, case-law, regulations, codes of practice and policy guidance across the differing fields of law: mental health, mental capacity, community care, family and children’s rights. This book seeks to demystify this area of law.
