“Before you use your document you should read the notes in your travel document.” 10. Note 4 in the HOTD said: “4. If the holder obtains a national passport from their own Government, this travel document will no longer be valid and should be returned to the Travel Document Section immediately.”
“Illegal entrant” means a person - (a) unlawfully entering or seeking to enter in breach of a deportation order or of the immigration laws, or (b) entering or seeking to enter by means which include deception by another person, and includes also a person who has entered as mentioned in paragraph (a) or (b) above.”
“7.- (1) An Immigration Officer, whether or not in the United Kingdom, may give or refuse a person leave to enter the United Kingdom at any time before his departure for, or in the course of his journey to, the United Kingdom. (2) In order to determine whether or not to give leave to enter under this article (and, if so, for what period and subject to what conditions), an immigration officer may seek such information, and the production of such documents or copy documents, as an immigration officer would be entitled to obtain in an examination under paragraph 2 or 2A of Schedule 2 to the [Immigration Act 1971 ]. 13.- (1) In this article and article 13A ‘leave’ means - (a) leave to enter the United Kingdom (including leave to enter conferred by means of an entry clearance under article 2); and (b) leave to remain in the United Kingdom. (2) Subject to paragraph (3), where a person has leave which is in force and which was: (a) conferred by means of an entry clearance (other than a visit visa) under article 2; or (b) given by an immigration officer or the Secretary of State for a period exceeding six months, such leave shall not lapse on his going to a country or territory outside the common travel area.” … (4) Leave which does not lapse under paragraph (2) shall remain in force either indefinitely (if it is unlimited) or until the date on which it would otherwise have expired (if limited), but - (a) where the holder has stayed outside the United Kingdom for a continuous period of more than two years, the leave (where the leave is unlimited) or any leave then remaining (where the leave is limited) shall thereupon lapse; and …” (2) In order to determine whether or not to give leave to enter under this article (and, if so, for what period and subject to what conditions), an immigration officer may seek such information, and the production of such documents or copy documents, as an immigration officer would be entitled to obtain in an examination under paragraph 2 or 2A of Schedule 2 to the [Immigration Act 1971 ]. (a) leave to enter the United Kingdom (including leave to enter conferred by means of an entry clearance under article 2); and (b) leave to remain in the United Kingdom. (2) Subject to paragraph (3), where a person has leave which is in force and which was: (a) conferred by means of an entry clearance (other than a visit visa) under article 2; or (b) given by an immigration officer or the Secretary of State for a period exceeding six months, such leave shall not lapse on his going to a country or territory outside the common travel area.” … (4) Leave which does not lapse under paragraph (2) shall remain in force either indefinitely (if it is unlimited) or until the date on which it would otherwise have expired (if limited), but - (a) where the holder has stayed outside the United Kingdom for a continuous period of more than two years, the leave (where the leave is unlimited) or any leave then remaining (where the leave is limited) shall thereupon lapse; and …”
“18. A person seeking leave to enter the United Kingdom as a returning resident may be admitted for settlement provided the Immigration Officer is satisfied that the person concerned: (i) had indefinite leave to enter or remain in the United Kingdom when he last left; and (ii) has not been away from the United Kingdom for more than 2 years; and (iii) did not receive assistance from public funds towards the cost of leaving the United Kingdom; and (iv) now seeks admission for the purpose of settlement. 19. A person who does not benefit from the preceding paragraph by reason only of having been away from the United Kingdom too long may nevertheless be admitted as a returning resident if, for example, he has lived here for most of his life. … 20. The leave of a person whose stay in the United Kingdom is subject to a time limit lapses on his going to a country or territory outside the common travel area if the leave was given for a period of six months or less or conferred by a visit visa. In other cases, leave lapses on the holder remaining outside the United Kingdom for a continuous period of more than two years. A person whose leave has lapsed and who returns after a temporary absence abroad within the period of this earlier leave has no claim to admission as a returning resident. His application to re-enter the United Kingdom should be considered in the light of all the relevant circumstances. The same time limit and any conditions attached will normally be reimposed if he meets the requirements of these Rules, unless he is seeking admission in a different capacity from the one in which he was last given leave to enter or remain.”
“it was common ground, throughout that the applicant did not put a foot wrong. He did not produce any other documents, nor did the immigration officer ask for any others. The applicant said that the Immigration Officer did not ask any questions but simply stamped the passport ‘Immigration Officer Gatwick’ and the date” (Peter Pain J).”
“clearly contemplate the possibility that there is a new and further principle here, namely that if the immigration officer had no authority to grant the particular permission which was granted that vitiates the permission and renders the leave void.”
“A duty is cast on all persons who are examined by immigration officers (either on arrival or departure) to answer any questions put to them, say what documents they may be carrying and to produce their passport or other identity document … There is no duty to volunteer unsolicited information, and a person will not be an illegal entrant if they accidentally and without intention to mislead offer incorrect information, and silence accompanied by conduct can in some circumstances amount to a false representation … See Khawaja v Secretary of State for the Home Department[1984] 1 AC 74 …”
