Section 138 Order of examinations.
Witnesses shall be first examined-in-chief, then (if the adverse party so desires) cross-examined, then (if the party calling him so desires) re-examined.
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 examination-in-chief.
Direction of re-examination.
The re-examination shall 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.
Cross-examination of plaintiff without conducting examination-in-chief of plaintiff is not permissible. Under section 138, cross-examination follows chief-examination, but not without chief-examination; Smt. Shardamma v. Kenchamma, AIR 2007 Kant 17.
