Most involuntary mental health admissions are under the Mental Health Act 1983. Importantly, this Act codified the professional roles of those with the power to apply for the detainment of a patient, specifically those powers held by an Approved Social Worker (ASW), and stipulated specific staff training for any individuals administering the act (Rapaport and Manthorpe, 2009). The Mental Health Act 1995 then gave authorities new powers over those discharged from hospital.
