Extensions of time limits
7.—(1) The relevant police authority may extend the period referred to in rule 5(1) or (2) or 6(3) in any case where the authority is satisfied, on the application of the appellant, that by reason of the special circumstances of the case it is just to do so; and in such a case rules 5 and 6 shall have effect as if for that period there were substituted such extended period as the authority may specify.
(2) Where the relevant police authority refuses an application by the appellant under paragraph (1), it shall give the appellant notice in writing of the reasons for the decision and of the right of appeal conferred by paragraph (3).
(3) An appellant whose application under paragraph (1) is refused may, not later than 14 days after receiving notice under paragraph (2), appeal in writing to the chairman of the tribunal against the decision of the relevant police authority.
(4) The chairman may, on such an appeal, make any decision which the relevant police authority had power to make under paragraph (1); and, where he extends the period referred to in rule 5(1) or (2) or 6(3), rules 5 and 6 shall have effect as if for that period there were substituted such extended period as the chairman may specify.
