a Court to call for any evidence deemed essential for the just and appropriate decision of the case, has not been debarred. The rules are hand-maidens of administration of justice. Making a reference to the issues framed in the present case, whether the defendant executed an agreement to sell in favour of plaintiff on 30.05.1995, is to be proved by the plaintiff. In order to rebut the same the defendant has placed on record, the report of an expert. In view of the said circumstances, the plaintiff-respondent will have to establish that the thumb impression existing on the agreements belong to defendantpetitioner. The trial Court in order to ascertain the truth and to arrive at just conclusion pertaining to the agreements, in the exercise of jurisdiction vested in it, has directed the defendant to furnish thumb impressions of her fingers which exercise seems to be in consonance with the fair rules of administration of justice. Besides this, no prejudice will be caused to the petitioner, rather it will support her pleadings in case the the pleadings regarding non-existence of her thumb impressions on the agreement is true.
