PROOF OF A DOCUMENT MERE MARKING OF DOCUMENT IS NOT ENOUGH

In Narbada Devi Gupta Vs. Birendra Kumar Jaiswal (2003) 8 SCC 745, where Supreme Court observed as follows:- "The legal position is not in dispute that mere production and marking of a document as exhibit by the court cannot be held to be a due proof of its contents. Its execution has to be proved by admissible evidence, that is, by the "evidence of those persons who can vouchsafe for the truth of the facts in issue".
