What the cross examination is
Cross examination is the examination of a witness in a legal proceeding by the adverse party.
It takes place after examination-in-chief: the examination of a witness by the party who calls him. Cross examination is followed by re-examination: the examination of the witness subsequent to the cross examination by the party who called him. The section 137 of the Indian Evidence Act, 1872 (IEA) defines these terms.
The Chapter X (Section 135 to 166) of the IEA deals with legal provisions relating to examination of witnesses. But the examination of witness is much more than what the law speaks of, in terms of skills needed, quality ensured and the outcome it brings out in the process. This write up is exclusively on cross examination.
Don’t confuse cross examination with a deposition of witness. Deposition is to find out information but cross examination is to ascertain the truth of the facts in question.
