“The power under this Act to give or refuse leave to enter the United Kingdom shall be exercised by immigration officers, and the power to give leave to remain in the United Kingdom, or to vary any leave under section 3(3)(a) (whether as regards duration or conditions), shall be exercised by the Secretary of State; and, unless otherwise allowed by or underthis Act, those powers shall be exercised by notice in writing given to the person affected, except that the powers under section 3(3)(a) may be exercised generally in respect of any class of persons by order made by statutory instrument.”
“Notice of immigration decision (1) The Secretary of State may make regulations requiring a person to be given written notice where an immigration decision is taken in respect of him. (2) The regulations may, in particular, provide that a notice under subsection (1) of a decision against which the person is entitled to appeal under section 82(1) must state— (a) that there is a right of appeal under that section, and (b) how and when that right may be exercised. (3)The regulations may make provision (which may include presumptions) about service.”
“Notice of decisions 4.—(1) Subject to regulation 6, the decision-maker must give written notice to a person of any immigration decision or EEA decision taken in respect of him which is appealable. (2) The decision-maker must give written notice to a person of the relevant grant of leave to enter or remain if, as a result of that grant, a right of appeal arises under section 83(2) of the 2002 Act. (3) If the notice is given to the representative of the person, it is to be taken to have been given to the person.”
“For the purpose ofsection 3C of the Immigration Act 1971 an application for variation of leave is decided— (a) when notice of the decision has been given in accordance with regulations made undersection 105 of the Nationality, Immigration and Asylum Act 2002 (1); or where no such notice is required, (b) when notice of the decision has been given in accordance withsection 4(1) of the Immigration Act 1971 .”
“Notice of liability (section 10) The IS151A Part 1 (Notice that a person is to be treated as an illegal entrant/a person liable to administrative removal undersection 10 of the Immigration & Asylum Act 1999 ) can be served on those liable to administrative removal (as outlined in the first five bullet points above). The Notice of Liability is not an appealable immigration decision. It informs the individual they are an illegal entrant/immigration offender and they are liable to detention and removal. It also allows reporting restrictions to be placed on the individual. See Section 51.5 below. Statement of reasons To comply with the requirement set out in regulation 5(1)(a) of theImmigration (Notices) Regulations 2003 , the IS.151A Part 1 must contain a statement of reason(s). A non-exhaustive list of paragraphs that could be copied and pasted into the IS151A Part 1 are listed below. The wording should then be amended to fit the individual circumstances of the case: … … Service The Notice of Liability can be served in person or by post. However, in deception an interview under caution by an immigration officer may be required first. See Chapter 37 for further details on enforcement interviews ...”
“… the clerk of the peace…shall in due course give notice to the appellant, to the other party to the appeal, and to the clerk to the court of summary jurisdiction as to the date, time and place fixed for the hearing of the appeal. A notice required by this sub-section to be given to any person may be sent by post in a registered letter addressed to him at his last or usual place of abode.”
“It is argued that it is sufficient to comply with s 3(1) if he send a registered letter to the respondent, even though it is not received by him, and known not to be received. I do not think that is correct. When construing this section, it is to be remembered that it is a fundamental principle of our law that no one is to be found guilty or made liable by an order of any tribunal unless he has been given fair notice of the proceedings so as to enable him to appear and defend them. … This could be done by proof that a notice had been sent to him in good time by post in a registered letter which had not been returned, for it could then be assumed that it had been delivered inthe ordinary course of post: see the Interpretation Act, 1889, s 26.”
“Under Section 3(3) of the 1971 Act a limited leave to enter or remain in the United Kingdom may be varied by extending or restricting its duration, by adding, varying or revoking conditions or by removing the time limit (where upon any condition attached to the leave ceases to apply). When leave to enter or remain is varied an entry is to be made in the applicant's passport or travel document (and his registration certificate where appropriate) or the decision may be made known in writing in some other appropriate way.”
“References to service by post. E+W+S+N.I. Where an Act authorises or requires any document to be served by post (whether the expression “serve” or the expression “give” or “send” or any other expression is used) then, unless the contrary intention appears, the service is deemed to be effected by properly addressing, pre-paying and posting a letter containing the document and, unless the contrary is proved, to have been effected at the time at which the letter would be delivered in the ordinary course of post.”
"Section 26 of the Interpretation Act, 1889, throws no light upon the matter. It has no application where the statute to be interpreted says nothing about service by post."
