They also contended that based on the partition dated 20.03.1993, revenue records were brought out in the name of defendant No.1. They also claimed that the plaintiffs were signatories to the palupatti dated 20.03.1993. Though this document was marked as Ex.D66 subject to objection, this document could still be looked into for collateral purposes namely that plaintiffs and defendant No.1 had severed the status of joint family. If that be so, the defendant Nos.6 to 8 were bound to prove execution of the palupatti dated 20.03.1993. No doubt, the defendants Nos.6 to 8 could have availed the opportunity of leading evidence of a witness to Ex.D66 at the earliest point in time. They could not have laid low from the stage of the evidence of the defendants till the arguments in the suit was addressed by the plaintiffs and defendant Nos.4 and 5. However, since this was a crucial fact that defendant Nos.6 to 8 had to prove to establish that the sale in their favour is just and lawful, an opportunity deserves to be granted to the defendant Nos.6 to 8, but however on terms.
