“You are not required to leave the United Kingdom as a result of this decision. You still have leave to enter or remain where your current conditions continue to apply under25th November 2014 . Please ensure that you understand the conditions of your stay … Although you are not required to leave the United Kingdom at this time your leave to enter or remain in the United Kingdom is due to expire on25th November 2014 . You need to make arrangements to plan your departure before your leave expires. If you intend to remain in the United Kingdom after this time you should make a further application for leave before your current leave expires.”
“A person’s leave to enter or remain in the United Kingdom shall lapse on his going to a country or territory outside the Common Travel Area (whether or not he lands there), unless within the period for which he had leave he returns to the United Kingdom in circumstances in which he is not required to obtain leave to enter; but, if he does so return, his previous leave (and any limitation on it or conditions attached to it) shall continue to apply.”
“20A. Leave to enter or remain in the United Kingdom will usually lapse on the holder going to a country or territory outside the Common Travel Area. However, under Article 13 of theImmigration (Leave to Enter and Remain) Order 2000 such leave will not lapse where it was given for a period exceeding six months or where it was conferred by means of an entry clearance (other than a visit visa)”
“If you are curtailing leave so that some leave remains, you must also include the following line: “If you leave the UK your leave to enter or remain will lapse under Article 13(3) of theImmigration (Leave to Enter and Remain) Order 2000 and you may require a visa to enter the UK”
“Until the amendments brought about by theImmigration and Asylum Act 1999 , a person’s leave to enter or remain in the UK lapsed on his or her leaving the Common Travel Area. This meant that many persons with limited leave (as students, for example) who left the UK for a short holiday were refused leave to enter on their return, because they did not have an entry clearance or visa. The provisions of theImmigration (Leave to Enter and Remain) Order 2000 has put an end to this anomaly. Leave to enter or remain does not lapse when the holder goes abroad, if it was conferred by an entry clearance (other than a visit visa) or by an Immigration Officer or the Secretary of State for more than six months. There appear to be two exceptions. First,Section 3C of the Immigration Act 1971 … Secondly, that where leave has already been varied by the Secretary of State and, following the variation, there is less than six months left, it will lapse on leaving the UK.” Mr Blundell relies upon the emphasised passage.
