4. Both, vendor Babu Ram and the subsequent vendees from him, came up in the first Appeal. The First Appellate Court found that both, plaintiff and defendant No.1, are the real brothers and co-owners in joint holding and the agreement (exhibit P-1) was found to have been executed by defendant No.1. However, on the issue of bonafide purchaser pertaining to defendants No.2 and 3, the First Appellate Court has found that once Sube Singh, transferee (DW3) has stated that he had no notice of any such agreement to Sell between Babu Ram and the plaintiff, it was for the plaintiff to prove by producing evidence that he had the knowledge. It was also observed that the time gap between the two transactions was too short that there was no chance for the vendees for gaining knowledge of the earlier agreement. On the basis of these findings, defendants No.2 and 3 were held to be bonafide purchasers. However, the First Appellate Court had found that both the plaintiff and defendant No.1 were co-owners to the extent of land measuring 186 kanals 13 ma
