Where a party adduces evidence—
(a) that contradicts evidence already given in examination-in-chief by a witness called by some other party; or
(b) about a matter as to which a witness who has already been called by some other party was able to give evidence in examination-in-chief,
and the evidence adduced has been admitted, the court may, if the first mentioned party did not cross-examine the witness about the matter to which the evidence relates, give leave to the party who called the witness to recall the witness to be questioned about the matter.
