Section 37 IPC - Cooperation by Doing One of Several Acts Constituting an Offence

Section 37 of the Indian Penal Code, 1860 dealt with an offence committed through several acts. A person who intentionally cooperated in committing that offence by doing any one of those acts, either alone or jointly with another person, committed the offence.

Legal position covered: This article explains Section 37 IPC under the law applicable immediately before the Bharatiya Nyaya Sanhita, 2023 came into force on 1 July 2024. For earlier conduct and proceedings, the applicable law and relevant savings provisions must be considered according to the facts and date of the alleged offence.

Section 37 of the Indian Penal Code 1860

Section 37 - Cooperation by doing one of several acts constituting an offence.

When an offence is committed by means of several acts, whoever intentionally co-operates in the commission of that offence by doing any one of those acts, either singly or jointly with any other person, commits that offence.

Illustrations to Section 37 IPC

Illustration (a): A and B agree to murder Z by severally and at different times giving him small doses of poison. A and B administer the poison according to the agreement with intent to murder Z. Z dies from the effects of the several doses of poison so administered to him. Here A and B intentionally cooperate in the commission of murder and, as each of them does an act by which the death is caused, they are both guilty of the offence though their acts are separate.

Illustration (b): A and B are joint jailors and, as such, have charge of Z, a prisoner, alternatively for six hours at a time. A and B, intending to cause Z's death, knowingly cooperate in causing that effect by illegally omitting, each during the time of his attendance, to furnish Z with food supplied to them for that purpose. Z dies of hunger. Both A and B are guilty of the murder of Z.

Illustration (c): A, a jailor, has charge of Z, a prisoner. A, intending to cause Z's death, illegally omits to supply Z with food; in consequence of which Z is much reduced in strength, but the starvation is not sufficient to cause his death. A is dismissed from his office, and B succeeds him. B, without collusion or cooperation with A, illegally omits to supply Z with food, knowing that he is likely thereby to cause Z's death. Z dies of hunger. B is guilty of murder, but, as A did not cooperate with B, A is guilty only of an attempt to commit murder.

Meaning and Scope of Section 37 IPC

Section 37 applied where the commission of one offence consisted of several acts and different persons intentionally cooperated by performing one or more of those constituent acts. A participant did not have to perform every act making up the offence. The statutory requirement was intentional cooperation in the commission of the offence by doing one of the acts through which it was committed.

The provision therefore connected an individual's intentional contribution with the complete offence produced through several acts. The words "intentionally co-operates" were important: Section 37 did not state that accidental, independent or unconnected conduct was sufficient.

Essential Ingredients of Section 37 IPC

An offence must be committed by means of several acts.
The person concerned must cooperate in the commission of that offence.
The cooperation must be intentional.
The person must do at least one of the several acts through which the offence is committed.
The relevant act may be done singly or jointly with another person.
When the statutory conditions are fulfilled, the cooperating person commits the offence.

Why Intentional Cooperation Matters

The three statutory illustrations show the importance of intentional cooperation. Illustration (a) concerns separate positive acts performed under an agreement. Illustration (b) concerns coordinated illegal omissions. Illustration (c), by contrast, expressly removes collusion or cooperation between the two jailors and therefore reaches a different result for the first jailor.

Section 37 consequently required the connection between the participant's act and the cooperative commission of the offence to be established; it was not merely a rule that everyone whose conduct happened to form part of a sequence was automatically guilty of the completed offence.

Section 37 and Illegal Omissions

Illustration (b) confirms that the several acts contemplated by Section 37 could operate together with legally relevant omissions. Section 32 IPC provided that, unless a contrary intention appeared from the context, words referring to acts done extended also to illegal omissions. Section 33 IPC further explained the expressions "act" and "omission."

Section 36 IPC separately dealt with an effect caused partly by an act and partly by an omission. These provisions formed part of the IPC's general framework for determining criminal responsibility where conduct involved multiple acts or omissions.

Section 37 Compared with Sections 34, 35 and 38 IPC

Provision	Principal subject
Section 34 IPC	Criminal act done by several persons in furtherance of the common intention of all.
Section 35 IPC	An act criminal by reason of criminal knowledge or intention and done by several persons.
Section 37 IPC	Intentional cooperation by doing one of several acts through which an offence is committed.
Section 38 IPC	Persons concerned in a criminal act may be guilty of different offences.

Separate Acts Can Form One Offence

Illustration (a) demonstrates that the constituent acts need not occur at exactly the same time. A and B administer separate doses of poison at different times pursuant to their agreement. Their acts are separate, but each intentionally cooperates in the murder by performing an act contributing to the death.

The legal focus under Section 37 was therefore not simply whether each participant personally performed the entire physical sequence. The question was whether the offence was committed through several acts and whether the person intentionally cooperated by doing one of them.

Absence of Cooperation

Illustration (c) is equally significant because it describes B as acting "without collusion or co-operation with A." The illustration distinguishes independent conduct from intentional cooperation. It shows why the existence of a sequence of acts or omissions by different people did not, by itself, satisfy Section 37.

Practical Application

Application of Section 37 required consideration of the ingredients of the substantive offence, the several acts or legally relevant omissions through which it was committed, the role of each participant and the evidence of intentional cooperation. The provision supplied a general rule of criminal responsibility; proof of the particular offence and the required mental element remained necessary.

Position Before the Bharatiya Nyaya Sanhita 2023

The Indian Penal Code, 1860 governed substantive criminal law before the Bharatiya Nyaya Sanhita, 2023 came into force on 1 July 2024. This article intentionally presents Section 37 in its pre-BNS setting. The law applicable to a particular incident depends on the date and circumstances of the alleged offence and the relevant transitional and savings provisions.
