That section places a duty on PCTs (in England), Local Health Boards (in Wales) and local social services authorities (in both England and Wales) to provide after-care for people who have been detained in hospital for treatment for mental disorder under the Act. They must provide such after-care, in co-operation with relevant voluntary agencies, until such time as they are satisfied that the person is no longer in need of such services, or (where applicable) for at least as long as the person remains on supervised community treatment under the Act. 447 Section 117 is a free-standing duty. Case-law has established that after-care services required by this duty are provided under section 117 itself, not under the legislation under which most social services and NHS services are provided. Case-law has also established that, in most cases, the duty falls on the local social services authority and PCT (or Local Health Board) for the area in which the person was resident before being detained (whether or not that body is responsible for other aspects of the person’s health or social care.). If there is no such area, the duty falls on the authorities for the area to which the person is sent on leaving hospital. 448 The main effect of this section is to transfer the duty on PCTs under section 117 to CCGs. As now, the duty will fall in the first place on the CCG for the area in which the person was resident before being detained. However, the new section 117(2E) inserted into the 1983 Act by this section would allow the Secretary of State to make regulations conferring the duty instead on another CCG or on the NHS Commissioning Board. 449 These regulations could, for example, be used to ensure that the CCG responsible for section 117 after-care for a patient was the same CCG that was responsible for commissioning other health services for the person in question under the NHS Act. (At present, the PCT responsible for section 117 after-care is not always the same as the PCT responsible for other aspects of a patient’s health care, especially where the patient moves while already in receipt of after-care). These regulations could also be used to deal with cases where a person’s after-care needs included services of the type that the NHS Commissioning Board, rather than CCGs, was responsible for commissioning under provisions earlier in this Act. In those cases, the regulations could say that it was the Board, rather than any individual CCG, which was responsible for commissioning such services as part of the person’s after-care under section 117. 450 The effect of new subsection (2D) is to make clear that the duty on a CCG (or the NHS Commissioning Board) is to commission, rather than provide, after-care. 451 The section also includes a number of technical changes to other provisions. 10 R. v Manchester City Council Ex p.Stennett [2002] UKHL 34; [2002] 4 All ER 124 11 R. v Mental Health Tribunal, Ex p.
