A reasonable time shall be given to the defendant and prosecutor for the preparation of the case. In no event shall the defendant be forced to attend the hearing without the aid of counsel if there is a reasonable probability of his securing counsel without too great delay. Where the hearing is postponed to a future day at the instance of either party or the court, it shall not be necessary to commit the defendant to jail pending the hearing; but he shall have the right to give bail for appearance at the hearing before the court of inquiry if the offense is bailable under the authority of the court.
