3. The original plaintiff namely Kaushali instituted Title Suit No. 132 of 2000 for redemption of mortgage deed dated 10.09.1984 executed by Late Kapildev Sharma. The original plaintiff Kaushali executed sale deed on 10.09.1984 in favour of Kapil Dev Sharma and on the same day Kapil Dev Sharma executed mortgage deed in favour of Kaushali stating therein that if the entire amount of consideration is returned within 7 years, the land shall be return back to Kaushali. The plaintiff did not pay the amount within the period prescribed but on request, Kapil Dev Sharma executed one Sada Agreement dated 03.03.1992 wherein the period stated in agreement dated 10.09.1984 was extended for another 7 years. After demise of Kapil Dev Sharma and after completion of period prescribed, the plaintiff approached the defendants and requested them to return back the documents which the defendant declined. Hence, the aforesaid suit filed for redemption of agreements dated 10.09.1984 and 03.03.1992 and thereafter for recovery of possession. The defendants in their written statement denied the existence of any Sada Agreement dated 03.03.1992.

The expert took photograph of all signatures mentioned in the all four deeds and submitted his report in the Court and thereafter expert was examined and cross-examined by the parties. The report of expert and photographs were made exhibits.

Further, he has submitted that the petitioner has a legal right to get report from the expert and the learned trial Court failed to exercise its jurisdiction.

6. On the other hand, learned counsel for the respondents has submitted that the petitioner at subsequent stage sought for relief to get compare signature of Kapil Dev Sharma only on two document which can not be allowed in the facts and circumstances of the case.

Only if the Court considers it necessary or expedient in the interest of justice to do so, it would issue a commission to such person as it think fit, directing him to inquire into such question and report thereon to the Court.
