No person shall be discharged from an order of commitment issued by any judicial or peace officer for want of bail, or in cases not bailable, on account of any defect in the charge or process, or for alleged want of probable cause; but in all such cases, the court or judge shall summon the prosecuting witnesses, investigate the criminal charge, and discharge, let to bail or recommit the prisoner, as may be just and legal, and recognize witnesses when proper.
R.L. 1910, § 4894.
