2.The first respondent has filed the suit in O.S.No.182 of 2013 for declaration and permanent injunction. The suit property originally belonged to the first revision petitioner / 1st defendant and he alienated the suit property by way of a registered sale deed dated 06.06.1983 in favour of one Natarajan, who in turn sold the same in favour of the first respondent / plaintiff by way of a registered sale deed dated 09.12.1983. According to the first revision petitioner / 1st defendant, out of 22 cents of land in S.No.199/9, he had sold only two cents of land in favour of the said Natarajan for discharge of his liability to repay the hand loan and the revision petitioner / 1st defendant has been in possession and enjoyment of the remaining land. According to the first respondent / plaintiff, though his predecessor in title viz., Natarajan has purchased 22 cents by way of registered sale deed dated 06.06.1983 and he has alienated the same in his favour by way of registered sale deed, dated 09.12.1983, in both the said sale deeds, the description of the property has been wrongly mentioned as 2 cents out of 22 cents in S.No.199/9 and 24 cents in S.No.199/5, instead of 22 cents in S.No.199/9. But, the four boundaries are correctly mentioned in the said sale deeds. While so, the first respondent / plaintiff has filed I.A.No.554 of 2013 seeking appointment of an Advocate Commissioner to measure the suit property by correlating the title document and parent document of the 1st respondent / plaintiff viz., sale deeds dated 06.06.1983 and 09.12.1983. The Court below has ordered the said application and appointed an Advocate Commissioner holding that it will be helpful for the Court to decide the dispute. Aggrieved by that order, the respondents 1 to 3 / defendants have filed this civil revision petition.
