s 140 Order of examinations and direction of re-examination
140.—(1) Witnesses are to be first examined‑in‑chief, then, if the adverse party so desires, cross‑examined, then, if the party calling them so desires, re‑examined. (2) The examination and cross-examination must relate to relevant facts, but the cross‑examination need not be confined to the facts to which the witness testified on his or her examination‑in‑chief. (3) The re-examination is to be directed to the explanation of matters referred to in cross-examination; and if new matter is, by permission of the court, introduced in re‑examination, the adverse party may further cross‑examine upon that matter. (4) The court may in all cases permit a witness to be recalled either for further examination-in-chief or for further cross‑examination, and if it does so, the parties have the right of further cross-examination and re‑examination respectively.
