Sh.Malkeet Singh, learned counsel for the plaintiff- appellant has vehemently contended that the appellant had admittedly purchased land out of Khasra No.26 and rect. No. 64 to the extent of 8 marlas and the land comprised in Khasra No.26 is recorded as Gair Mumkin Ahata Chah. A wrong inference has been drawn by the Courts below that Mohinder Kaur, mother of Sukhwant Singh, vendor of property, sold to defendant had become co-sharer. As a matter of fact, respondent No.1 had purchased land out of rect. No.63 whereas the land in dispute is in rect. No.64 as such respondent No.1 cannot become co-sharer with the appellant. He placed reliance on judgment of Inder Singh Vs. Om Parkash , 1990 (1) RRR 32. In the said judgment, a co-sharer had filed a suit for possession by preemption when the agriculture land had been sold in specific killa numbers and rect. numbers. It was held that when a co-sharer sells share out of defined part of joint land but not out of whole of their land, the sale will not be of a share out of joint land under Section 15 (1) (b)of the Punjab Preemption Act. The law laid down regarding rights of co-sharers in Bhartu Vs. Ram Saroop , 1981 PLJ 204 had been distinguished to be not applicable in the said case.
