Background : Britain's existing mental health legislation was introduced over 15 years ago. Since then, there has been considerable reorganisation of mental health care services but little research into the use of the Act in routine practice. Modernising Mental Health Services (1998) asserts that mental health legislation will be revised. Aim : The study investigates opinions about the strengths and weaknesses of Parts II and X of the Mental Health Act (1983) of those affected by it.
