Their members are appointed by the Lord Chancellor and include a doctor, a lawyer and a lay person (i.e. neither a doctor nor a lawyer). Detained persons have the right to be represented at MHRTs by a solicitor. Discharge from hospital as a result of an MHRT hearing is the exception to the rule, occurring in around 5% of cases, when the Tribunal judges that the conditions for detention are not met. Part II of the Act applies to any mentally disordered person who is not subject to the Criminal Justice System. The vast majority of people detained in psychiatric hospitals in England and Wales are detained under one of the civil sections of the Act. These sections are implemented following an assessment of the person suspected to be suffering from a mental disorder. These assessments can be performed by various professional groups, depending upon the particular section of the Act being considered. These professional groups include AMHPs, Section 12 approved doctors, other doctors, registered mental health nurses (RMNs) and police officers. Section 2 is an assessment order and lasts up to 28 days; it cannot be renewed. It can be instituted following an assessment under the Act by two doctors and an AMHP. At least one of these doctors must be a Section 12 approved doctor. The other must either have had previous acquaintance with the person under assessment, or also be a Section 12 approved doctor. This latter rule can be broken in an emergency where the person is not known to any available doctors and two Section 12 approved doctors cannot be found. In any case, the two doctors must not be employed in the same service, to ensure independence (this 'rule' was removed in the 2007 MHA amendment). Commonly, in order to satisfy this requirement, a psychiatrist will perform a joint assessment with a general practitioner (GP). A Mental Health Act assessment can take place anywhere, but commonly occurs in a hospital, at a police station, or in a person's home. If the two doctors agree that the person is suffering from a mental disorder, and that this is of a nature or to a degree that, despite his refusal to go to hospital, he ought to be detained in hospital in the interest of his own health, his safety, or for the protection of others, they complete a medical recommendation form and give this to the AMHP. If the AMHP agrees that there is no viable alternative to detaining the person in hospital, they will complete an application form requesting that the hospital managers detain the person. They will then be transported to hospital and the period of assessment begins.
