At that enquiry, evidence shall be heard as to such of the allegations as are not admitted, and the person charged shall be entitled to cross-examine the witnesses, to give evidence in person and to have such witnesses called as he may wish, provided that the officer conducting the enquiry may, for special and sufficient reasons to be recorded in writing, refuse to call a witness. Except in very special circumstances, no pleader or agent should be allowed to appear either on behalf of the Government or the accused either before the officer who conducts the enquiry or any, officer to whom appeal may be made.”
