(a) treat the applicant as fulfilling the requirement specified in paragraph 1(2)(a) or paragraph 1(2)(b), or both, although the number of days on which he was absent from the United Kingdom in the period there mentioned exceeds the number there mentioned ;

(b) treat the applicant as having been in the United Kingdom for the whole or any part of any period during which he would otherwise fall to be treated under paragraph 9(1) as having been absent;

(c) disregard any such restriction as is mentioned in paragraph 1(2)(c), not being a restriction to which the applicant was subject on the date of the application ;

(d) treat the applicant as fulfilling the requirement specified in paragraph 1(2)(d) although he was in the United Kingdom in breach of the immigration laws in the period there mentioned;

(e) waive the need to fulfil the requirement specified in paragraph 1(1)(c) if he considers that because of the applicant's age or physical or mental condition it would be unreasonable to expect him to fulfil it.
