"It is the Secretary of State's duty to provide throughout England and Wales, to such extent as he considers necessary to meet all reasonable requirements-- (a) hospital accommodation... (c) medical [and] nursing... services... (f) such other services as are required for the diagnosis and treatment of illness."
"(1) The Secretary of State may, where he considers it appropriate, arrange with any person or body (including a voluntary organisation) for that person or body to provide, or assist in providing, any service under this Act." "(3) The powers conferred by this section may be exercised on such terms as may be agreed, including terms as to the making of payments by or to the Secretary of State..."
"The person registered shall, having regard to the size of the home and the number, age, sex and condition of the patients therein-- (a) provide adequate professional... staff... (d) provide... adequate treatment facilities..."
"public bodies which are obviously public authorities (and which might be described as standard public authorities); public authorities defined as such under the Human Rights Act by virtue of carrying out some public functions (which might be described as functional public authorities); and courts and tribunals"
"The more closely the acts that could be of a private nature are enmeshed in the activities of a public body, the more likely they are to be public."
"not all the activities of private bodies (such as private companies) are subject only to private law. For example, the activities of a private body (such as a recently privatised company) may be governed by the standards of public law when its decisions are subject to duties conferred by statute or when, by virtue of the function it is performing, or possibly its dominant position in the market, it is under an implied duty to act in the public interest. A private company selected to run a prison, for example, although motivated by considerations of commercial profit, should be regarded, at least in relation to some of its activities, as subject to public law because of the nature of the function it is performing. This is because the prisoners, for whose custody and care it is responsible, are in the prison in consequence of an order of the court, and the purpose and nature of their detention is a matter of public concern and interest."
