16.—(1) Where the representatives of an assisted person consider that, owing to the circumstances of the case, if it proceeds to trial that trial would be likely to exceed 25 days, the solicitor (on behalf of himself and the advocate) may apply to the Commission for a Very High Cost Case Certificate and the Commission may, in its discretion, grant such application in accordance with paragraph (3).
(2) An application under paragraph (1) shall be made as soon as is practicable after the assisted person has been committed for trial (and, in any event, as soon as the representatives become aware that the trial is likely to exceed 25 days), and shall be submitted to the Commission in such form and manner as it may, in consultation with the taxing master, direct.
(3) When considering an application under paragraph (1) the Commission shall have regard, among the matters which are relevant, to such particulars, information and documents (including any Trial Status Report form) as the solicitor may have submitted.
(4) Where the Commission certifies a case as being a Very High Cost Case, it shall require the solicitor to provide periodic reports and projections as to the future costs of the case in such a form as the Commission shall direct.
(5) If a solicitor fails to comply with paragraph (4) without good reason, the Commission may revoke the Certificate, provided that the Certificate shall not be revoked unless the representatives have been permitted a reasonable opportunity to show cause orally or in writing why the Certificate should not be revoked.
(6) Where a Very High Cost Case Certificate has been revoked under paragraph (5), the representatives' fees shall be determined under rule 8 and rule 11, as appropriate, as if the Certificate had never been granted unless the actual duration of the trial exceeded 25 days.
(7) A solicitor (on behalf of himself and the advocate) may appeal to the taxing master against a decision made under this rule by the Commission and, subject to rule 19, such an appeal shall be instituted within 21 days of receiving notification of the decision by giving notice in writing to the taxing master.
(8) The provisions of rule 14(3), (4), (5), (10) and (13) shall apply with the necessary modifications to an appeal brought under paragraph (7).
(9) The decision of the taxing master on an appeal under paragraph (7) shall be final.
