produce a document after commencement of hearing of the suit. Though the statutory provision is not hedged in by any conditions for granting such leave, by judicial pronouncements, it is settled that a party has to satisfy the Court that in spite of due diligence, it could not produce the document along with the plaint. Undoubtedly, the petitioners failed to give reason for the belated production of the document which was admittedly in existence when the suit was filed. However, unless the Court feels that the party is guilty of gross negligence, ordinarily the request for production of additional evidence during the trial shall not be refused, for, the said additional evidence may help the Court to adjudicate the dispute in a proper and effectual manner. Though the petitioners ought to have given reasons for not filing the document along with the plaint, having regard to the fact that the evidence on the part of the petitioners is still not closed, the belated filing of the document cannot be viewed as constituting sole ground for its rejection.
