Definition and Nature of Crime – AIBE Notes

Crime, in its essence, is an act or omission that violates a law enacted to protect public welfare, carrying punishment prescribed by the State. Blackstone’s definition—“an act committed or omitted in violation of a public law either forbidding or commanding it”—remains influential in Indian law. The Bharatiya Nyaya Sanhita (BNS) 2023, India’s newly codified criminal statute, upholds these fundamentals, stating every person shall be liable to punishment for acts or omissions contrary to its provisions.

The concept of crime is rooted in two core elements:

Actus Reus (Guilty Act): The physical component—an act or omission forbidden by law.
Mens Rea (Guilty Mind): The mental element—an intention or knowledge to perform the forbidden act.

Together, these are summarized by the legal maxim: actus non facit reum nisi mens sit rea (“the act does not make one guilty unless the mind is guilty”).

Crimes can be classified by their impact:

Against person or body: Murder, assault, kidnapping
Property-related: Theft, robbery, fraud
Social order: Riots, public nuisance
Economic, cyber, or regulatory offences

Under BNS, ‘person’ covers both individuals and legal entities (companies, firms), enabling criminal liability to apply widely.

General Conditions Creating Criminal Liability

Criminal liability refers to an individual’s responsibility for a wrongful act, attracting punishment and societal discipline. The BNS and earlier the IPC define four main requirements:

A Human Being or Legal Person: Liability accrues to a ‘person’—natural or artificial (company, association).
Actus Reus: There must be an act or omission.
Mens Rea: Mental state such as intention, knowledge, recklessness, or even negligence, defined under various sections of BNS.
- Intention: Deliberate action to cause a result
- Knowledge: Awareness of probable harmful consequences
- Recklessness: Conscious disregard of a substantial risk
- Negligence: Failure to exercise reasonable care resulting in harm
Injury or Harm: The act must cause injury, whether physical, financial, reputational, or psychological, to another or society.

Recent BNS case laws (e.g., Section 101 – Murder, Section 106 – Death by Negligence) demonstrate how specific mental states lead to varying levels of liability.

Exceptional Conditions

General exceptions in BNS (Chapter 3) outline situations where liability is denied, typically due to absence of mens rea. E.g.:

Mistake of fact
Child under seven years
Unsound mind
These protect individuals who lack the required mental state.

Strict Liability under BNS: Meaning and Applications

Strict liability is a legal doctrine by which criminal responsibility is imposed regardless of the presence of mens rea in certain statutory offences. Its primary purpose is to protect public welfare in areas like public health, safety, or consumer protection.

Under the BNS, strict liability features prominently:

Section 106: Causing death by negligence—liability attaches for a negligent act leading to death even if there was no intent. The focus is on the negligent behaviour, not mental state.
Sections 137, 147, 152A: Cover regulatory offences and public safety concerns—liability is attached to the act itself.
Section 138: Offences related to negotiable instruments—punishment for wrongful acts (like cheque bounce) even without intent to defraud is possible.
Railways Act (Section 124-A) and Motor Vehicles Act (Sections 140, 163-A): Strict liability for railway and road accident compensation.

Rationale

Strict liability forfeits the need for mens rea in select cases because public interest, safety, and regulatory effectiveness are paramount. The classic case Sherras v De Rutzen (1895) established that such liability applies for public welfare offences.

Exceptions

The BNS also provides exceptions, often through general exceptions (e.g., infancy, insanity, necessity), safeguarding against unjust punishment where there truly was no fault.

Conclusion

The definition and nature of crime under India’s new criminal laws continue to follow time-tested principles—an act or omission coupled with a guilty mind causing harm. The BNS clarifies these components, distinguishing offences by mental state, and, in line with modern regulatory needs, establishes strict liability for certain offences to enhance public safety. Founders, employees, and the public at large must be aware that while most crimes require proof of intent or knowledge, some—by design—attach liability for mere wrongful conduct, even without intent to harm.
