A judge cannot listen to gossip, unrelated stories, or random complaints. There must be a strict rule to decide exactly what information is allowed into a trial and what must be kept out. It dictates that in any suit or proceeding, evidence may only be given concerning the facts in issue and relevant facts.
In the Indian court system, that rule is Section 3 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA). This section replaces the old rules of the 151-year-old Indian Evidence Act. It sets a simple, golden rule: You can only bring evidence to prove the main argument (facts in issue) or deeply connected details (relevant facts). You cannot bring anything else.
Whether a case is about a physical fight or a modern digital crime like leaked data, Section 3 sets the boundaries for what a lawyer can say and what a judge can look at.

1. What is Section 3 of the BSA?
Section 3 of the BSA acts as the ultimate gatekeeper for trials, ensuring legal proceedings remain focused, fast, and fair. The law explicitly states that evidence may be given in any suit or proceeding of the existence or non-existence of two specific categories—Facts in Issue and Relevant Facts—and of no others
The law says you can only give evidence about the existence or non-existence of two things:
- Facts in issue: The core things that one side claims happened and the other side denies.
- Relevant facts: Surrounding details that are logically connected to the core things.
- And of no others: This means if a piece of information is not a core issue and not connected, it is completely banned.
The Civil Case Exception: Section 3 states that you cannot use this law to bring in evidence if the standard rules of civil court have already banned you from using it. For example, if you forget to bring a contract to your first court hearing, you cannot use Section 3 as a trick to force the judge to look at it later.
Core Concepts: Breaking Down the Statutory Definitions
To fully understand how Section 3 functions, it is essential to decode the legal terminology into clear, accessible concepts.
A. What Qualifies as a “Fact”?
Under the law, a fact is not just a tangible object you can hold. It is divided into two distinct groups:
- Physical Facts: Anything capable of being perceived by the human senses. This includes things you can see, hear, taste, touch, or smell (e.g., a weapon found at a scene or a loud scream).
- Mental Facts: Any psychological or emotional condition that a person is conscious of. The law treats subjective states—such as a person’s intention, good faith, fraudulent mind, or a specific opinion—as verifiable facts.
B. What is a “Fact in Issue”?
This is the core engine of any legal battle. A fact in issue is the exact point of dispute that directly establishes, denies, or outlines the extent of a legal right, liability, or disability. When a judge formally records the precise points of disagreement between the prosecution and the defense, those points are the facts in issue.
C. What is a “Relevant Fact”?
A fact is considered relevant when it is logically and causally connected to a fact in issue, following the rules of relevancy laid down in the Act. While a relevant fact is not the primary point of dispute, it helps prove or disprove the core argument by providing context, motive, or preparation.
D. The Two Forms of “Evidence”
Section 3 recognizes two methods of presenting proof to establish these facts:
- Oral Evidence: All statements that the court permits or requires to be made before it by witnesses.
- Documentary Evidence: All documents, including electronic or digital records, produced for the inspection of the court.

Real-World Examples
To understand how Section 3 works, let’s look at two basic examples.
Example 1: A Murder Trial
Imagine Person A is accused of killing Person B by hitting him with a wooden stick on purpose.
At the trial, Section 3 says the lawyers can only talk about the specific questions in dispute:
If the prosecutor tries to bring in a witness to say that A’s cousin is a bad car driver, the judge will stop them. Why? Because that has nothing to do with the main questions, so it is blocked by Section 3.
Case Study 2: Proving a Digital State of Mind
- Proving an invisible mental state like “knowledge” or “intent” can be difficult. However, Section 3 shows how physical actions reveal mental facts.
- If Person A claims they had no idea a digital file in their possession was stolen, their state of mind is a fact in issue. If the prosecution introduces Person A’s phone browsing history, showing they searched “how to delete stolen files permanently” right before their arrest, that digital search is a physical fact. It directly proves a mental fact: Person A knew the file was stolen.
4. BSA vs. The Old Law
The BSA keeps the main ideas of the old Indian Evidence Act of 1872, but it makes the structure cleaner and ready for the modern world.
| Concept | The Old 1872 Law | The New BSA Law | Why It Matters |
| Rules for Relevance | Split up across different parts of the book. | Put together in Section 3. | It makes the law easier to read without jumping between pages |
| Digital Proof | Added digital records later as an afterthought. | Puts digital and electronic records right in the main definitions. | It treats WhatsApp texts, emails, and phone videos as normal evidence from day one. |
| “May Presume” | Written in a separate section later on. | Brought directly into Section 3(h). | Keeps all basic definitions and judge instructions in one single place. |
BSA Section 3 works like a filter for the truth. It makes sure that trials stay focused, fast, and fair. By setting a strict boundary line, it allows only the main arguments and closely connected details into the courtroom, while blocking out useless gossip and extra noise.
In today’s world, where cases involve thousands of text messages, emails, and digital files, this section is more important than ever. It gives judges and lawyers a clear rule book to find the truth efficiently, ensuring that Indian courts focus only on the facts that actually matter to the case.

Q: Can I bring any information I want to court to help my case?
A: No. Section 3 stops you from doing this. You can only bring proof that directly answers the main dispute or is clearly connected to it. Random background stories are not allowed.
Q: What is the difference between a physical fact and a mental fact?
A: A physical fact is something you can perceive with your senses, like a stick used in a fight or a loud scream. A mental fact is something inside the mind, like a bad intention, an opinion, or a feeling of anger. Both can be brought up in court under Section 3.
Q: What exactly is a “fact in issue”?
A: A “fact in issue” is the core point of dispute in a case. It represents any fact that directly establishes, denies, or outlines the extent of a legal right, liability, or disability being argued in court. In simple terms, when a judge states the formal point of disagreement between two sides, those points are the facts in issue
