Discharge of prosecutor or witness on own recognizance in cases not capital; costs

When any prosecutor or witness in criminal cases less than capital is committed to jail for inability to give surety on his recognizance to prosecute or testify, the clerk of court of general sessions in which the case is pending may, in his discretion, discharge such prosecutor or witness on his own recognizance. Clerk's costs, not to exceed one dollar, may be charged for each such recognizance taken.
