Power to direct attendance of party whose agent cannot answer material question

If the agent of either party is unable to answer any material question relating to the case, which the Deputy Commissioner is of opinion that the party whom he represents ought to answer and likely to be able to answer if interrogated in person, the Deputy Commissioner may postpone the hearing of the case to a future day, and may direct that such party shall attend in person on such day, and, if such party fails to appear in person on the day appointed, the Deputy Commissioner may decide the suit as in case of default, or make such other order as he may deem proper in the circumstances of the case.
