4. In the instant case, admittedly, the trial of the suit commenced and posted for the evidence of defendants. Therefore, the prohibition contained in the first part of the proviso to Rule 17 of Order VI got attracted. The petitioners were under obligation to plead the reasons to satisfy the Court as to what prevented them from seeking amendment before the commencement of the trial. The affidavit filed by the petitioners in support of the I.A. is silent, in this regard. Further, in the written statement filed by the deceased defendant No.1, it is mentioned therein the year 1988 and as such, the trial Court held that there cannot be any typographical mistake and the said proposed amendment is only an after-thought and dismissed the I.A. by the order impugned. Therefore, I am of the view that there is no illegality or irregularity in the order impugned warranting interference by this Court.
