(2) If the Secretary of State is satisfied that the review can properly be made without a formal hearing, he shall inform the person making the request of its refusal and of the reason for that refusal and may proceed to review the determination without such a hearing, but he shall not proceed to make his review of the determination until he has allowed the person making the request at least 21 days to make any written submissions in connection with the review.
(3) If, in accordance with the provisions of paragraph (1), a request for a formal hearing has been granted, or if no request has been made but the Secretary of State is otherwise satisfied that a formal hearing is desirable, reasonable notice (being at least 21 days or such lesser period as the Secretary of State, with the agreement of all persons to whom notice of the hearing has been given, may think fit) of the time and place of the hearing shall be given to every person to whom notice of the application has been given under paragraph (4) of regulation 3.
(4) In any case in which a formal hearing of a review is held such hearing shall be in public except where the Secretary of State is satisfied that, by reason of the confidential or sensitive nature of matters raised, it is just and reasonable for the hearing or any part of it to be in private.
