Section 99 in Indian Evidence Act 1872
Title: Who may give evidence of agreement varying terms of document
Persons who are not parties to a document, or their representatives in interest, may give evidence of anyfacts tending to show a contemporaneous agreement varying the terms of the document.
A and B make a contract in writing that B shall sell A certain cotton, to be paid for on delivery. At the same time they make an oral agreement that three months credit shall be given to A. This could not be shown as between A and B, but it might be shown by C, if it affected his interests.
Title: Saving of provisions of Indian Succession Act relating to wills
Nothing in this Chapter contained shall be taken to affect any of the provisions of the Indian Succession Act, 1865 1(10 of 1865) as to the construction of wills.
1. See now the Indian Succession Act, 1925 (39 of 1925), Pt. VI, Ch. VI.
Title: Burden of proof
Whoever desires any Court to give judgment as to any legal right or liability dependent on the existence of facts which he asserts, must prove that those facts exist. When a person is bound to prove the existence of any fact, it is said that the burden of proof lies on that person.
(a) A desires a Court to give judgment that B shall be punished for a crime which A says B has committed. A must prove that B has committed the crime.
(b) A desires a Court to give judgment that he is entitled to certain land in the possession of B, by reason of facts which he asserts, and which B denies, to be true. A must prove the existence of those facts.
Title: On whom burden of proof lies
The burden of proof in a suit or proceeding lies on that person who would fail if no evidence at all were given on either side.
(a) A sues B for land of which B is in possession, and which, as A asserts, was left to A by the will of C, B's father.
If no evidence were given on either side, B would be entitled to retain his possession.
Therefore the burden of proof is on A.
(b) A sues B for money due on a bond.
The execution of the bond is admitted, but B says that it was obtained by fraud, which A denies.
If no evidence were given on either side, A would succeed, as the bond is not disputed and the fraud is not proved.
Therefore the burden of proof is on B.
Title: Burden of proof as to particular fact
The burden of proof as to any particular fact lies on that person who wishes the Court to believe in its existence, unless it is provided by any law that the proof of that fact shall lie on any particular person.
1[(a)] A prosecutes B for theft, and wishes the Court to believe that B admitted the theft to C. A must prove the admission.
(b) B wishes the Court to believe that, at the time in question, he was elsewhere. He must prove it.
1. Sic, in the Act as published in Gazette of India, 1872, Pt. IV, p. 1 there is no illustration (b).
