‘This decision is not an immigration decision under section 82. Section 82(2)(d) [of the 1999 Act] concerns ‘a refusal to vary a person’s leave to enter or remain in the United Kingdom if the result of the refusal is that the person has no leave to enter or remain’
“(1) person who is not a British citizen may be removed from the United Kingdom in accordance with directions given by an immigration officer, if (a) having only a limited leave to enter or remain, he does not observe a condition attached to the leave or remains beyond the time limited by the leave; (b) he uses deception in seeking (whether successfully or not) leave to remain; … (8) When a person is notified that a decision has been made to remove him in accordance with this section, the notification invalidates any leave to enter or remain in the United Kingdom previously given to him …”
“(1) A person may not appeal under section 82(1) while he is in the United Kingdom unless his appeal is of a kind to which this section applies.
“… Khawaja establishes that the non-existence of a precedent fact relating to immigration status can deprive the decision-maker of power to decide and render any purported decision void …”
“The only coherent solution, it seems to me, is to continue to regard every question arising under section 10 as in principle both appealable and reviewable ...but to calibrate the use of judicial review, through the exercise of judicial discretion, to the nature of the issue or issues. In this way – and in so far as I can see, in no other way – the High Court can remain loyal to what was decided in Khawaja by consistently retaining jurisdiction to determine the existence of preconditions of liability to removal, as well as other questions of law apt for the High Court’s determination, but can also respect the policy of section 82 by declining to entertain challenges on issues more apt for the appeal mechanism, whatever its hardships.”
“there is no challenge …to the fact that the decision to remove was made under section 10”
