"Any case in which it appears to the immigration officer as a result of a claim or information given by the person seeking entry at a port that he might fall within the terms of this provision is to be referred to the Home Office for decision regardless of any grounds set out in any provision of these rules which may appear to justify refusal of leave to enter. Leave to enter will not be refused if removal would be contrary to the provisions of the Convention and Protocol relating to the Status of Refugees."
"In the exercise of their functions under this Act immigration officers shall act in accordance with such instructions (not inconsistent with the immigration rules) as may be given them by the Secretary of State ..."
"(1) • • • where a person examined by an immigration officer under paragraph 2 above is to be given a limited leave to enter the United Kingdom or is to be refused leave, the notice giving or refusing leave shall be given not later than twelve hours after the conclusion of his examination (including any further examination) in pursuance of that paragraph; and if notice giving or refusing leave is not given him before the end of those twelve hours, he shall ... be deemed to have been given indefinite leave to enter the United Kingdom and the immigration officer shall as soon as may be give him written notice of that leave."
"Very often an examination may have to be adjourned pending further inquiries, and then resumed after the replies are received. It is not 'concluded' until all information is to hand. In this case it was not concluded until the telex reply was received at 1.30 pm on September 15th."
"In three of the cases the Home Office letter specifically stated that it had reached a decision on asylum, and in all cases the attached sheet specifically stated that the asylum application was refused. In the letters, the attached sheets and the Home Office instructions, there is no word of the decisions being provisional or subject to further representations or further examination and, for my part, I am quite unable to regard the giving of an opportunity to make further representations as coming within any reasonable meaning of the words 'further examination'."
