It may be observed that the section gives an option to the cross examiner. He may cross-examine the witness on the writing and if he is satisfied with the answer given by the witness or if he does not intend to pursue the matter further, he is not required to show the writing to the witness or to prove the writing. But if the cross-examiner intends to contradict the witness by the writing, then he must show the writing to the witness and call his attention to those parts of the writing which are to be used for the purpose of contradicting the witness. It is only after this condition has been complied with that the writing can be admitted in evidence. The cross-examination of the Respondent which Mr. Ajayi relied on as having complied with the provisions of the section may now he examined.
