“Authority to prosecute: I confirm that I neither received the consent of, nor authorisation from the Secretary of State to commence these proceedings. This is because by virtue of the Carltona principle, derived from Carltona Ltd v Commissioner of Works[1943] 2 All ER 560 , I am the Secretary of State for these purposes.”
“… acts done in exercise of those functions are equally acts of the minister, whether they are done by him personally, or through his departmental officials, as in practice, except in matters of the very first importance, they almost invariably would be done.”
“It is also possible that the performance of statutory ministerial functions by officials, or by particular officials, may be inconsistent with the intention of Parliament as evinced by the relevant provisions. In such circumstances, the operation of the Carltona principle will be impliedly excluded or limited.”
