(b) A conditional judgment must, on motion of such party, be entered against such witness and a notice issued to him that such judgment will be made absolute unless he appears within 30 days from the date of the service of such notice and renders a good excuse for his default; and, if he fails to appear and render a satisfactory excuse for his default, such judgment may be made absolute or reduced, as the court may direct.
