Introduction
The Bharatiya Sakshya Adhiniyam (BSA), 2023 modernizes India’s law of evidence and replaces the Indian Evidence Act, 1872. Among its important provisions is Bharatiya Sakshya Adhiniyam (BSA) Section 5 deals with the relevancy of facts that are connected with the occasion, cause, or effect of facts in issue or relevant facts. In legal proceedings, an incident rarely happens alone. Every event has a background, reason, surrounding circumstances, and consequences.
The court does not only examine the main disputed fact but also looks at connected facts that help explain how and why an event occurred. These surrounding circumstances may reveal the opportunity, reason, or impact of an incident.
Bharatiya Sakshya Adhiniyam, 2023 places Section 5 under the chapter dealing with the relevancy of facts.
For law students, advocates, judicial aspirants, and legal professionals, understanding BSA Section 5 is important because it explains when surrounding facts become admissible evidence.
What Is BSA Section 5?
BSA Section 5: Facts which are the occasion, cause, or effect of an incident
Those facts are considered legally necessary (relevant) which are the direct cause or effect of a main incident or facts connected to it. In addition, the circumstances under which that incident took place, or which provided an opportunity for that incident to occur, are also considered necessary.
This section is one of the easiest and most important parts of the law of evidence, which is based on the following principles:
This section considers those facts to be relevant which are the:
- Occasion: The background in which the incident occurred.
- Cause: The reason due to which the incident took place.
- Effect: The immediate or later visible impact or consequence of the incident.
- Opportunity: The chance obtained to commit/execute the incident.
- State of Things: The circumstances or conditions under which that incident occurred.
This broader approach allows courts to understand the complete context surrounding a case.

Understanding Occasion, Cause, and Effect Under Section 5
What Is an Occasion?
An occasion refers to a circumstance that creates an opportunity for a fact in issue to occur.It does not directly cause the event but provides the setting in which the event becomes possible.
Example of Occasion:Suppose a company office remains open after working hours because of a technical issue.A theft later occurs during that period.The office remaining open may be considered the occasion that enabled the incident.A cause refers to the factor that directly produces or contributes to a particular event.Courts frequently examine causal relationships to determine responsibility and liability.
What Is a Cause?
Example of Cause : A driver operates a vehicle while intoxicated.The vehicle collides with another car.The intoxication may be considered a cause of the accident.
Why Cause Matters
Establishing causation can help courts:
- Determine negligence.
- Establish criminal liability.
- Identify responsibility.
- Assess compensation claims.
What Is an Effect?
An effect refers to the consequence or result arising from a disputed event.Evidence of consequences often helps establish that an event actually occurred.
Example of Effect: A person allegedly commits fraud.Following the transaction, the victim suffers substantial financial losses.Those losses may be relevant because they demonstrate the effect of the alleged conduct.
Common Types of Effects
- Physical injuries
- Property damage
- Financial loss
- Emotional trauma
- Business disruption
How Courts Apply Section 5 in Practice
Courts apply Section 5 by identifying whether a fact helps explain the background, origin, or consequence of a disputed matter.Judges examine the logical relationship between the proposed evidence and the fact in issue.
Establishing a Logical Connection:The evidence must not be remote or speculative.Instead, it should have a direct and meaningful relationship with the disputed event.
Example
If an employee is accused of embezzlement, records showing unusual financial transactions shortly before the alleged offense may become relevant.These transactions may explain the circumstances leading to the misconduct.
Determining Relevance
Courts often ask:
- Does the fact explain why the event occurred?
- Does it reveal the circumstances surrounding the incident?
- Does it show a consequence of the disputed act?
- Is there a reasonable connection between the facts?
If the answer is yes, the evidence may be admitted under Section 5.
Why Is BSA Section 5 Important in Evidence Law?
Section 5 is important because it helps courts reconstruct the full story behind a disputed event.
Without contextual evidence, judges may only see fragments of an occurrence. The law therefore permits evidence that explains the circumstances leading to or resulting from an event.
For example, if a person is accused of theft, evidence showing how the accused gained access to the property may become relevant because it explains the occasion for the alleged offense.
Similarly, evidence showing financial loss after fraud may be relevant because it demonstrates the effect of the alleged act.
Key Benefits of BSA Section 5
- Provides complete factual background.
- Assists courts in determining truth.
- Establishes logical connections between events.
- Prevents important evidence from being excluded.
- Supports fair and informed judicial decisions.

Difference Between Section 4 and Section 5 of BSA
Many students confuse Section 4 and Section 5 because both deal with relevancy.
However, they serve different purposes.
| Basis | Section 4 | Section 5 |
| Main Concept | Same Transaction | Occasion, Cause, or Effect |
| Focus | Connected Events | Contextual Circumstances |
| Legal Principle | Res Gestae | Causal Relationship |
| Purpose | Complete Event Narrative | Explain Background and Consequences |
| Example | Victim’s Immediate Statement | Circumstances Leading to Incident |
Practical Difference
Section 4 focuses on events forming part of a single occurrence.
Section 5 focuses on circumstances that explain why something happened or what happened afterward.
Illustrations of BSA Section 5
Illustration 1: Theft Case
An employee possesses duplicate keys to a warehouse.A theft occurs during the night.The employee’s access to the keys may be relevant because it provided the occasion for the offense.
Illustration 2: Road Accident
A driver ignores traffic signals and exceeds the speed limit.An accident follows shortly afterward.The traffic violations may be relevant because they contributed to the cause of the collision.
Illustration 3: Fraud Investigation
A person transfers money to multiple bank accounts before a suspected fraud.The transactions may explain the planning and circumstances surrounding the alleged misconduct.
Illustration 4: Assault Matter
A victim suffers serious injuries after an altercation.Medical reports documenting those injuries may become relevant because they show the effect of the alleged attack.
Landmark Judicial Decisions Related to Section 5 Principles

- Sharad Birdhichand Sarda v. State of Maharashtra
- Hanumant Govind Nargundkar v. State of Madhya Pradesh
These judgments continue to influence the interpretation of evidence under the modern framework.
