Section 128 BNS: Force

Section 128 of the Bharatiya Nyaya Sanhita, 2023 (BNS) defines when a person is said to use "force" to another person. It is a foundational definition for the provisions that follow on criminal force and assault.

Current law: The Bharatiya Nyaya Sanhita, 2023 is Act No. 45 of 2023. Its provisions, except Section 106(2), came into force on 1 July 2024.

What Section 128 BNS Means

A person is said to use force to another when the person causes motion, change of motion, or cessation of motion to that other person.

Force also includes causing motion, change of motion, or cessation of motion to a substance in such a way that the substance comes into contact with any part of the other person's body, anything that person is wearing or carrying, or anything so situated that the contact affects that person's sense of feeling.

The Three Statutory Ways Force May Be Caused

Section 128 recognizes three ways in which the required motion, change of motion, or cessation of motion may be produced:

Section 128(a) By the person's own bodily power.
Section 128(b) By arranging or disposing a substance so that the motion, change of motion, or cessation of motion occurs without any further act by that person or any other person.
Section 128(c) By inducing an animal to move, change its motion, or cease to move.

Essential Elements of "Force" under Section 128

Important: Section 128 is a definition provision. It defines "force" but does not by itself prescribe a punishment. Whether use of force becomes criminal depends on the requirements of the applicable substantive provision, including Section 129 BNS on criminal force.

Force through Bodily Power

Clause (a) covers force created by a person's own physical action. A direct push, pull, stop, or movement may fall within this category where the statutory definition is otherwise satisfied.

Force through a Substance

Clause (b) covers situations in which a person arranges or disposes a substance in such a way that motion, change of motion, or cessation of motion occurs without any further act by that person or by anyone else. This shows that physical contact by the accused's own body is not essential to the definition of force.

Force through an Animal

Clause (c) covers force caused by inducing an animal to move, change its motion, or stop moving. The statutory definition therefore extends beyond direct human physical contact.

Force and Criminal Force: Section 128 vs Section 129

Section 128 supplies the basic legal definition of force. Section 129 BNS then defines when intentional use of force without consent amounts to criminal force, including where it is used to commit an offence or with the required intention or knowledge concerning injury, fear, or annoyance.
