Section 33 IPC: Act and Omission
Section 33 of the Indian Penal Code, 1860 explained the meaning of the expressions "act" and "omission". It made clear that either expression could refer to one occurrence or to a series of occurrences.
Text of Section 33 IPC
The word "act" denotes as well a series of acts as a single act: the word "omission" denotes as well a series of omissions as a single omission.
Meaning of "act" under Section 33 IPC
For the purposes of the IPC, an "act" was not confined to one isolated physical act. Section 33 expressly provided that the word could denote either a single act or a series of acts. The provision therefore allowed other IPC sections using the word "act" to be read according to the context without artificially limiting the expression to one individual step.
Meaning of "omission" under Section 33 IPC
Likewise, an "omission" could mean a single omission or a series of omissions. Section 33 itself did not make every failure to act criminal. Criminal liability for an omission depended on the particular penal provision and, where relevant, the existence of a legal duty to act.
Why Section 33 was important
- It was a general definition provision in Chapter II of the IPC.
- It clarified that references to an act could include connected conduct consisting of several acts.
- It similarly clarified that an omission could consist of repeated or continuing failures rather than only one failure.
- It had to be read with the substantive IPC provision that created the offence or imposed liability.
Section 32 and Section 33 IPC read together
Section 32 IPC provided that, unless a contrary intention appeared from the context, words referring to acts done also extended to illegal omissions. Section 33 complemented that rule by explaining that an "act" or "omission" could be singular or consist of a series.
Related provisions
The concept also connects with Section 36 IPC, which dealt with an effect caused partly by an act and partly by an omission, and Section 43 IPC, which defined "illegal" and "legally bound to do".
Position after commencement of the BNS
The Bharatiya Nyaya Sanhita, 2023 came into force on 1 July 2024, subject to the notified exception concerning Section 106(2). Under the BNS definitions provision, "act" and "omission" continue to be defined so that each may include a series as well as a single act or omission. For conduct and proceedings governed by the post-commencement regime, consult the applicable BNS provisions and relevant saving or transitional rules rather than relying only on the former IPC section.
Frequently asked questions
Did Section 33 IPC create a separate offence?
No. Section 33 was a definition provision. It explained the scope of the words "act" and "omission" when those expressions were used in the IPC.
Could an "act" mean several acts?
Yes. Section 33 expressly stated that "act" included a series of acts as well as a single act.
Could an "omission" mean repeated failures to act?
Yes. The definition included a series of omissions as well as a single omission. Whether a particular omission attracted criminal liability depended on the substantive law applicable to the facts.
