Krishnan Samban and thereafter, on his death, his three sons viz., Munian, Dhasan and Perumal had partitioned the property and the suit property, was allotted to the share of Munian. Munian died intestate leaving behind his only son namely Sellappan. Sellappan sold an extent of 1.23 cents of land to one Thilagam under registered Sale Deed dated 12.07.1974 and retained for himself an extent of 31 cents. The plaintiffs are the children of the Sellappan. It is their case that the property which was sold by the said Sellappan was exchanged by the said Thilagam with one Vivekanandham and on the death of Vivekanandham, his wife Dr.V.Manonmani, the first defendant and son, the second defendant succeeded to the estate. The plaintiff case was that the defendants had encroached into an entire extent of 1.53 cents over and above the extent sold to them. Therefore, pending suit, the petitioners have taken out the interlocutory application seeking the permission for appointment of an Advocate Commissioner to inspect the suit property and measure the same and file the report with plan in respect of the extent of lands admeasuring 1.23 acres and 31 cents respectively. The petition was opposed by the respondents and ultimately, it was dismissed by the learned Judge stating that this is a fact that can be proved by documents, challenging which order the above Civil Revision Petition has been filed.
