(2)Order X, Rule 2, empowered the Court at the first or any subsequent hearing to examine any party appearing in person or present in Court, or any person by whom the party or his pleader is accompanied and who is able to answer material questions. This does not include a pleader but does include a person having knowledge of material facts who accompanies the pleader. This power (under Order X, Rule 2) is intended to be used by the Judge only when he finds it necessary to obtain from such party information on any material question. It is not intended as a substitute for pleadings or as a substitute for trial.
