Only a doctor registered with the GMC can prescribe medication. A doctor may do so within the NHS, or when practising privately. A private hospital does not ordinarily provide a public service under the control of the State, and therefore would not be an emanation of the State as that term is understood in EU law. A private hospital may however provide such a service when it is contracted by an NHS body to provide a service which would otherwise be provided by the NHS.
In addition, a private mental hospital which detains people under sections 2 or 3 of the Mental Health Act 1983 would be in that respect a public body for the purposes of judicial review and human rights law.
