(a) A is tried for the murder of B. The facts that A murdered C, that B knew that A had murdered C, and that B had tried to extort money from A by threatening to make his knowledge public, are relevant.
(b) A sues B upon a bond for the payment of money. B denies the making of the bond. The fact that, at the time when the bond was alleged to be made, B required money for a particular purpose, is relevant.
(c) A is tried for the murder of B by poison. The fact that, before the death of B, A procured poison similar to that which was administered to B, is relevant.
(d) The question is, whether a certain document is the will of A. The facts that, not long before, the date of the alleged will, A made inquiry into matters to which the provisions of the alleged will relate; that he consulted advocates in reference to making the will, and that he caused drafts of other wills to be prepared, of which he did not approve, are relevant.
(e) A is accused of a crime. The facts that, either before, or at the time of, or after the alleged crime, A provided evidence which would tend to give to the facts of the case an appearance favourable to himself, or that he destroyed or concealed evidence, or prevented the presence or procured the absence of persons who might have been witnesses, or suborned persons to give false evidence respecting it, are relevant.
(f) The question is, whether A robbed B. The facts that, after B was robbed, C said in A's presence—"the police are coming to look for the person who robbed B", and that immediately afterwards A ran away, are relevant.
(g) The question is, whether A owes B ten thousand rupees. The facts that A asked C to lend him money, and that D said to C in A's presence and hearing—"I advise you not to trust A, for he owes B ten thousand rupees", and that A went away without making any answer, are relevant facts.
(h) The question is, whether A committed a crime. The fact that A absconded, after receiving a letter, warning A that inquiry was being made for the criminal, and the contents of the letter, are relevant.
(i) A is accused of a crime. The facts that, after the commission of the alleged crime, A absconded, or was in possession of property or the proceeds of property acquired by the crime, or attempted to conceal things which were or might have been used in committing it, are relevant.
(j) The question is, whether A was raped. The fact that, shortly after the alleged rape, A made a complaint relating to the crime, the circumstances under which, and the terms in which, the complaint was made, are relevant. The fact that, without making a complaint, A said that A had been raped is not relevant as conduct under this section, though it may be relevant as a dying declaration under clause (a) of section 26, or as corroborative evidence under section 160.
(k) The question is, whether A was robbed. The fact that, soon after the alleged robbery, A made a complaint relating to the offence, the circumstances under which, and the terms in which, the complaint was made, are relevant. The fact that A said he had been robbed, without making any complaint, is not relevant, as conduct under this section, though it may be relevant as a dying declaration under clause (a) of section 26, or as corroborative evidence under section 160.
Legal Commentary & Landmark Judgments: Section 6
Section 6 establishes the relevancy of facts showing motive, preparation, and previous or subsequent conduct of any party or their agent in relation to facts in issue.
Explanation 1 clarifies that the word 'conduct' does not include mere statements unless those statements accompany and explain acts other than statements. Explanation 2 clarifies that statements made in the presence and hearing of a person whose conduct is in question are relevant if they affected such conduct.
Section 6 links psychological motivation to physical reality. Motive supplies the missing link in circumstantial chains, while preparation (purchasing poison, scouting terrain) and subsequent conduct (fleeing the jurisdiction or displaying abnormal panic) provide corroboration of guilt.
