BSA Section 7: Facts Necessary to Explain or Introduce a Fact in Issue or a Relevant Fact (Evidence Act 9 Mapping) (2026)
What Section 7 of the Bharatiya Sakshya Adhiniyam (BSA) really does: it makes relevant the facts needed to explain or introduce a fact in issue or relevant fact, support or rebut an inference, fix identity, time or place, or show a relationship, and how it maps to the old Section 9 of the Indian Evidence Act.

Section 7 of the Bharatiya Sakshya Adhiniyam (BSA), the new evidence law in force since 1 July 2024, makes relevant the facts that are needed to explain or introduce a fact in issue or a relevant fact. It replaced Section 9 of the Indian Evidence Act, 1872. Watch the numbers: the old "Section 9 IEA" is now BSA Section 7, and the old Section 7 IEA (occasion, cause and effect) has moved to BSA Section 5. This explainer sets out what Section 7 really covers and how it maps to the old law. Last verified October 2026.
- New section: facts necessary to explain or introduce is Section 7 of the BSA, in force since 1 July 2024.
- Old section: it replaced Section 9 of the Indian Evidence Act, 1872.
- Watch the shift: the old Section 7 IEA (occasion, cause and effect) is now Section 5 of the BSA.
- Purposes: explain or introduce, support or rebut an inference, fix identity, time or place, or show a relationship, only so far as necessary.
01Clearing up the section number
The BSA renumbered the relevancy sections, and this is a common trap. The old Section 9 of the Indian Evidence Act, facts necessary to explain or introduce, is now Section 7 of the BSA. The old Section 7 of the Evidence Act, occasion, cause and effect, has moved to Section 5 of the BSA.
So if you carry the old numbers across, you land on the wrong rule. This page is about BSA Section 7, which is the explain or introduce rule.
02What Section 7 covers
Section 7 lets a party prove the facts that make the main evidence intelligible or complete. A fact is relevant so far as it is necessary to do any of the following:
- Explain or introduce a fact in issue or a relevant fact;
- support or rebut an inference suggested by a fact in issue or relevant fact;
- establish the identity of a thing or a person whose identity is relevant;
- fix the time or place at which a fact in issue or relevant fact happened; or
- show the relationship of the parties by whom any such fact was transacted.
Only so far as necessary
The section carries its own limit. These facts are relevant only to the extent that they are needed for one of the listed purposes. A party cannot use it to drag in unrelated matter under the guise of explanation.
03How it works, with examples
The illustrations show the range of the section:
- Identity: evidence that fixes the identity of a thing or a person, such as test identification, fits here where identity is relevant.
- Explaining conduct: where an accused sudden departure from home is in issue, proof that he had urgent business elsewhere can explain the conduct. The details of that business stay out unless needed to show the urgency.
- Relationship (libel): in a suit over a libel, the position and relationship of the parties when the libel was published can be introductory to the facts in issue.
- Will dispute: where the question is whether a document is a will, the state of the maker property and family on the relevant date can be relevant.
Each example is tied to necessity: the fact comes in because it is needed to explain, introduce, identify, locate in time or place, or show a relationship.
04Old to new: IEA 9 to BSA 7
Section 9 of the Indian Evidence Act is now Section 7 of the BSA. The surrounding relevancy sections shifted down by two, so it helps to see the group together.
| Rule | Old law (Evidence Act) | New law (BSA) |
|---|---|---|
| Evidence of facts in issue and relevant facts | Section 5 | Section 3 |
| Occasion, cause or effect | Section 7 | Section 5 |
| Motive, preparation and conduct | Section 8 | Section 6 |
| Facts necessary to explain or introduce | Section 9 | Section 7 |
The occasion, cause and effect rule that sits just before it is now Section 5 of the BSA.
05Is it an offence? Classification
Section 7 does not create an offence, so there is no cognizable, bailable or triable label to apply to it, and it carries no punishment. It is a rule of relevancy in the law of evidence.
Relevancy rules decide what may be proved in a trial, civil or criminal. The cognizable or bailable question belongs to the offence being tried, not to a section of the evidence law.
06What changed from the old law
For this rule, the main change is the number. The text follows Section 9 of the Indian Evidence Act, with the heading now adding the words "fact in issue or", so the body of case law on explaining and introducing facts, and on identity evidence, still guides how Section 7 of the BSA is read.
The practical lesson is to re-learn the numbers. Read Section 7 with the general relevancy rule in Section 3 and with Section 5 of the BSA on occasion, cause and effect.

09Frequently asked questions
What does Section 7 of the BSA cover?
Section 7 of the Bharatiya Sakshya Adhiniyam, 2023 makes relevant the facts needed to explain or introduce a fact in issue or relevant fact, to support or rebut an inference, to establish identity, to fix the time or place, or to show the relationship of the parties, so far as necessary. It replaced Section 9 of the Indian Evidence Act, 1872.
Is BSA Section 7 the same as the old Section 7 of the Evidence Act?
No. The old Section 7 of the Evidence Act, occasion, cause and effect, is now Section 5 of the BSA. The old Section 9, facts necessary to explain or introduce, is what became Section 7 of the BSA.
Does Section 7 cover identification evidence?
Yes. Section 7 makes relevant facts that establish the identity of a thing or a person whose identity is relevant, which is the basis on which identity evidence, including a test identification, is admitted so far as necessary.
Does old case law on Section 9 of the Evidence Act still apply?
In large part, yes. Because the text is carried over, with the heading adding the words "fact in issue or", judgments on Section 9 of the Indian Evidence Act still guide how Section 7 of the BSA is read.
Is BSA Section 7 an offence section?
No. Section 7 is a rule of evidence and creates no offence. It carries no punishment, so cognizable or bailable labels do not apply to it. It only decides what facts may be proved in a trial.
Can I research how courts apply Section 7 in Claw?
Yes. Claw lets you search more than 30 crore judgments on Section 7 or the old Section 9, by provision, party or advocate, with results in under 5 seconds, and track orders and hearings across 9,102 courts, benches and forums. It researches and tracks the matter but does not give legal advice.
