BSA Section 4: Facts Forming Part of the Same Transaction, Res Gestae (Evidence Act 6 Mapping) (2026)

Explainer · Evidence Law · BSA

Updated for 2026 · Claw Editorial

Section 4 of the Bharatiya Sakshya Adhiniyam (BSA), the new evidence law in force since 1 July 2024, makes facts that form part of the same transaction relevant. This is the rule lawyers know as res gestae. If you still look up "Section 6 of the Evidence Act", this is the provision you now need. It lets a court receive the words, acts and events that surround the main fact, because they explain it. This explainer sets out what Section 4 covers, how it maps to the old law, and what changed. Last verified October 2026.

01A common mix-up on the number

Many notes online still tie "Section 4" of evidence law to the terms "may presume", "shall presume" and "conclusive proof". That mapping belonged to the old Indian Evidence Act, 1872. The BSA has renumbered the code, so the same-numbered section no longer means the same thing.

Under the BSA, those three presumption terms are now defined in the interpretation clause, Section 2(1). Section 4 of the BSA instead carries the res gestae rule that used to sit in Section 6 of the old Act. So if you are reading a post-1 July 2024 matter, Section 4 is about facts forming part of the same transaction, not about presumptions.

02What Section 4 says

Section 4 of the BSA makes a fact relevant when it is so connected with a fact in issue or a relevant fact that the two form part of the same transaction. The fact becomes relevant whether it happened at the same time and place, or at different times and places.

The section keeps the old illustrations. For example, where a person is beaten to death, the things said or done by the attackers, the victim and the bystanders at or near the beating are part of the same transaction and are relevant. In a case about successive deliveries of goods, each delivery is a relevant fact that forms part of the one transaction.

03What "same transaction" means

A "transaction" is a group of acts so connected together as to be regarded as one single event. Courts look for closeness in time, place, cause and continuity of action. The classic test for a spoken statement is whether it was made at the moment of the event, or so soon after that there was no real chance to make it up.

This is why a spontaneous cry during an attack can come in as res gestae, while a calm account given hours later, after time to think, usually cannot. The link to the main fact must be natural and unbroken.

04Old to new: Evidence Act 6 to BSA 4

Section 6 of the Indian Evidence Act, 1872 is now Section 4 of the BSA. The wording and the illustrations are carried over almost unchanged, so the doctrine is the same.

So the relevancy sections moved back by two numbers. The old Section 6 became Section 4, the old Section 8 became Section 6 of the BSA, and the old Section 10 became Section 8 of the BSA.

05How it is used in practice

Section 4 helps both sides. The prosecution uses it to bring in the natural noise around a crime: a shout, a struggle, a victim naming the attacker in the heat of the moment. The defence uses it to show the full sequence, which may support self-defence or a sudden fight.

Because the wording is carried over, the large body of case law built under Section 6 of the old Act still guides how Section 4 is read. Counsel quote the same leading judgments on spontaneity and continuity, now under the new number.

06What changed

The substance did not change. The change is the section number and some modern, plain language. The same transaction test, the same illustrations, and the same limits on delayed statements all carry over.

The practical point is simple. In a matter on or after 1 July 2024, cite Section 4 of the BSA. In an older matter, the citation stays as Section 6 of the Evidence Act, because the law that applies is the law on the date of the proceeding. For how presumptions now work, that content sits in the definitions in Section 2(1), not in Section 4.

07Where Claw fits

Claw is an all-in-one legaltech platform for Indian advocates, law firms, and corporate legal teams, combining AI-based case search, an AI legal assistant (Legal GPT), case management, and compliance automation across all Indian courts and tribunals.

Res gestae is raised in trial courts across India every day, from assault to road accident to commercial disputes, and the same transaction test is applied differently from bench to bench. Claw carries more than 30 crore judgments, with Supreme Court rulings from 1950 and High Court rulings from 1990, and returns results in under 5 seconds. It tracks cases, orders and hearings across 9,102 courts, benches and forums, so you can see how Section 4, or the old Section 6, has read spontaneity and continuity and follow a live matter by party or advocate name.
