Section 4 of the Indian Evidence Act: May Presume, Shall Presume and Conclusive Proof
Section 4 of the Indian Evidence Act, 1872 established three important rules about legal presumptions. These rules determine whether a court has discretion to infer a fact, must presume a fact subject to rebuttal, or must treat a fact as conclusively proved.
Meaning of the three presumptions
1. May presume: discretionary and rebuttable
Under former Section 4, when the Act stated that a court may presume a fact, the court could treat the fact as proved unless disproved, or require proof of it. This is a discretionary presumption.
Current provision: BSA Section 2(1)(h). A court assesses whether the circumstances justify drawing the inference.
2. Shall presume: mandatory but rebuttable
Under former Section 4, when the Act directed that a court shall presume a fact, it had to regard that fact as proved unless and until it was disproved. The opposing party may still offer evidence to rebut the presumption.
Current provision: BSA Section 2(1)(l). The obligation to presume arises only when the statutory conditions are met.
3. Conclusive proof: no rebuttal of the declared consequence
Under former Section 4, where the Act declared one fact to be conclusive proof of another, proof of the first required the court to regard the second as proved, without allowing evidence solely to disprove that second fact.
Current provision: BSA Section 2(1)(b). Whether the foundational fact is established, and whether a statutory exception applies, remain important questions.
Difference between may presume, shall presume and conclusive proof
| Expression | Court's duty | Can it be rebutted? |
|---|---|---|
| May presume | May infer the fact or require proof | Yes |
| Shall presume | Must presume when legal conditions are met | Yes |
| Conclusive proof | Must accept the declared consequence once the foundational fact is proved | Not by evidence aimed at disproving that consequence, subject to the statute |
Practical illustrations under Indian evidence law
Discretionary presumption: Under BSA Section 119, a court may presume facts likely to have happened in the ordinary course of natural events, human conduct, or business, having regard to the circumstances of the case.
Mandatory rebuttable presumption: Under BSA Section 118, where the statutory ingredients concerning dowry death are established, the court shall presume that the accused caused the dowry death. The presumption remains rebuttable.
Conclusive proof: BSA Section 116 deals with legitimacy of a child born during a valid marriage or within the prescribed period after its dissolution, subject to the statutory no-access exception. The exact conditions of that section must be considered.
Text of Section 4 of the Indian Evidence Act, 1872
The former provision used the following three definitions:
"May presume". Whenever it is provided by this Act that the Court may presume a fact, it may either regard such fact as proved, unless and until it is disproved, or may call for proof of it.
"Shall presume". Whenever it is directed by this Act that the Court shall presume a fact, it shall regard such fact as proved, unless and until it is disproved.
"Conclusive proof". When one fact is declared by this Act to be conclusive proof of another, the Court shall, on proof of the one fact, regard the other as proved, and shall not allow evidence to be given for the purpose of disproving it.
Which evidence law applies after 1 July 2024?
Section 170(1) of the BSA repeals the Indian Evidence Act, 1872. Section 170(2) saves applications, trials, inquiries, investigations, proceedings and appeals pending immediately before 1 July 2024, directing that they be dealt with under the former Act as then in force. For other matters, the BSA is the operative central evidence legislation, subject to applicable law and judicial interpretation.
