IMPORTANT CASE LAWS
1. Objective of Section 91 of the Act:
Roop Kumar vs Mohan Thedani, AIR 2003 SC 2418 : “……Section 91 relates to evidence of terms of contract, grants and other disposition of properties reduced to form of document. This section merely forbids proving the contents of a writing otherwise than by writing itself; it is covered by the ordinary rule of law of evidence, applicable not merely to solemn writings of the sort named but to others known some times as the “best evidence rule”. It is in reality declaring a doctrine of the substantive law, namely, in the case of a written contract, that of all proceedings and contemporaneous oral expressions of the thing are merged in the writing or displaced by it……….”
2. Section 91 and 92 of the Act:
R. Janakiraman v. State, (2006) 1 SCC 697 : “….Section 92 is supplementary to Section 91 and corollary to the rule contained in Section 91………The rule contained in Section 92 will apply only to the parties to the instrument or their successors-in-interest. Strangers to the contract (which would include the prosecution in a criminal proceeding) are not barred from establishing a contemporaneous oral agreement contradicting or varying the terms of the instrument. On the other hand, Section 91 may apply to strangers also…..”
