Clause 186

Witnesses for the prosecution and the defence whose attendance before the High Court is necessary and who have appeared before the examining Magistrate pursuant to section 179(3) or whose written statements have been admitted by the examining Magistrate under that section shall execute bonds binding themselves to be in attendance when called upon at the High Court to give evidence.

If any witness refuses to execute such bond, the examining Magistrate may commit him to prison until the trial or until he gives satisfactory security that he will give evidence at the trial.
