“It is still open to the Secretary of State in her discretion to grant leave to enter or remain to an alien whose application does not meet the requirements of the Immigration Rules. It is for her to determine the practice to be followed in the administration of the Act. But the statutory context in which those powers are being exercised must be respected. As their source is the 1971 Act itself, it would not be open to her to exercise them in a way that was not in accordance with the rules that she has laid before Parliament.” and at para 33: “But the scope of that duty is now defined by the statute. The obligation under section 3(2) of the 1971 Act to lay statements of the rules, and any changes in the rules, cannot be modified or qualified in any way by reference to the common law prerogative. It excludes the possibility of exercising prerogative powers to restrict or control immigration in ways that are not disclosed by the rules.”
“they are not the product of active debate in Parliament, and non-nationals seeking leave to enter or remain are not in any event represented there”
“In the circumstances, Paragraph 320(7A)/(7B) of the Immigration Rules must be assessed on the footing that it is executive’s attempt (as opposed to Parliament’s attempt) to mandatorily exclude certain individuals from the United Kingdom. ”
“…in this instance Parliament has deliberately, by section 7, conferred a rule making power on the Authority. It is for the Authority to draw up what it believes are the appropriate criteria for the grant of licences for door supervisors. The criteria are challengeable only on the grounds of ultra vires, Wednesbury irrationality or lack of proportionality.”
“This argument not only infringes the prescription of the “no fetter” principle itself (as he reads it), which assumes that there is an exception to every case, but, more importantly, it is not, in my view, supported by authority or legal policy. Lord Reid was careful, in the passage cited from British Oxygen, to refer to “the general rule.”
“The purpose and scope of the scheme is to be gleaned from its language rather than statements as to its broad objective. It has been carefully framed and its purpose is plainly not to compensate people like Mrs Elias who do not satisfy the birth link. ... I see no basis for saying that because the government agrees to make payments in a certain class of situations, that it is now obliged to consider applications from those who do not fall within the rules in a different way than it would otherwise have done. In my judgment it is not obliged in every case effectively to consider extending the scheme on a case by case basis beyond the scope which it has carefully delineated. The court's task is to give effect to the scheme established by the Crown in the same way as it would a scheme established by legislation. It is no more an unfair or unlawful exercise of power for the Crown, acting through the Minister, to refuse to consider exceptional cases under the common law scheme than it would have been under a statutory scheme”
