was examined being the registered document to say that Amirsai had not executed the sale deed and it was got executed fraudulently by defendants No.1 & 2. Heavy burden lies on the plaintiff in the light of Section 101 of the Indian Evidence Act, 1872 to prove the fact of execution of sale deed by third person in the name of Amirsai which the plaintiff has miserably failed to prove. Non-production of document which the plaintiff claimed to be the inoperative document and that too by serious allegation of impersonation is fatal to the plaintiff and the plaintiff was duty bound to produce, mark and exhibit it to prove the fact of non-execution of the same by Amirsai which the plaintiff failed to do. On the other hand, Lalobai – plaintiff No.1, wife of Amirsai examined as PW-2, has clearly admitted the execution of sale deed by her husband Amirsai in favour of defendants No.1 & 2 and relying upon the said admission, the trial Court dismissed the suit in favour of the defendants. But the first appellate Court made out a new ground to interfere with the said finding that the plaintiffs are aboriginals by caste and the present plaintiffs No.2 to 7 had also share in the suit property, therefore, Amirsai had no right to alienate the suit property in favour of defendants No.1 & 2 which is not the case brought before the Court by the plaintiffs in the plaint to be adjudicated upon.
