(2)If the convening officer so directs, counsel may appear on behalf of the prosecutor, but in that case, unless the notice under sub-rule (1) has been given by the accused, notice of the direction for counsel to appear shall be given to the accused at such time (not in any case less than seven days) before the trial, as would, in the opinion of the Court, have enabled the accused to obtain counsel to assist him at the trial.
