PART IV – PROVISIONS RELATING TO ALL CRIMINAL INVESTIGATIONS
EXAMINATION OF WITNESSES
150. Power to summon witnesses, or examine person present
A court may, at any stage of a trial or other proceeding under this Code, summon or call any person as a witness, or examine any person in attendance though not summoned as a witness, or recall and re-examine a person already examined, and the court shall summon and examine or recall and re-examine any such person if his evidence appears to it essential to the just decision of the case :
Provided that the prosecutor or the advocate for the prosecution or the defendant or his advocate shall have the right to cross-examine any such person, and the court shall adjourn the case for such time (if any) as it thinks necessary to enable the cross-examination to be adequately prepared if, in its opinion, either party may be prejudiced by the calling of that person as a witness.
151. Evidence to be given on oath
Every witness in a criminal cause or matter shall be examined upon oath, and the court before which any witness shall appear shall have full power and authority to administer the usual oath.
152. Refractory witnesses
(1) Whenever a person, appearing either in obedience to a summons or by virtue of a warrant, or being present in court and being verbally required by the court to give evidence—
(a) refuses to be sworn ; or
(b) having been sworn, refuses to answer any question put to him ; or
(c) refuses or neglects to produce any document or thing which he is required to produce ; or
(d) refuses to sign his deposition,
without offering sufficient excuse for his refusal or neglect, the court may adjourn the case for any period not exceeding eight days, and may in the meantime commit that person to prison, unless he sooner consents to do what is required of him.
(2) If the person, upon being brought before the court at or before the adjourned hearing, again refuses to do what is required of him, the court may again adjourn the case and commit him for the same period, and so again from time to time until the person consents to do what is so required of him.
(3) Nothing contained in this section shall affect the liability of any such person to any other punishment or proceeding for refusing or neglecting to do what is so required of him, or shall prevent the court from disposing of the case in the meantime according to any other sufficient evidence taken before it.
