 In such a situation, it is important, for the trial judge, the magistrate, the prosecution or defence counsel, to ensure that a statement is extracted from such a witness, which indicates that he agreed to tell the truth in his testimony.If this is not done, the testimony of such a witness may not furnish enough ground to prosecute him/her for perjury or for giving false evidence.Therefore, where a witness who refused to testify on oath or by affirmation, did not undertake to speak the truth, the entire process in such a proceeding may be described as a drama without any intent of it being basis for a criminal prosecution.
