Mens rea: intention, motive, malice, negligence and recklessness

1. Mens rea

Actus non facit reum nisi mens sit rea: an act does not make a man guilty unless his mind is guilty. Mens rea is the mental element required for liability. Salmond says it takes one of two forms, intention or negligence, and that a person is responsible for his wrongful act only if he did it wilfully or carelessly.

The Indian penal code contains no general clause requiring mens rea; each offence states its own mental element by words such as “intentionally”, “voluntarily”, “knowingly”, “dishonestly”, “fraudulently” or “with reason to believe”. Section 2(33) of the Bharatiya Nyaya Sanhita, 2023 defines “voluntarily”: a person causes an effect voluntarily when he causes it by means whereby he intended to cause it, or by means which he knew or had reason to believe to be likely to cause it. The general exceptions in sections 14 to 44 (mistake of fact, accident, infancy, unsoundness of mind, involuntary intoxication) operate as denials of mens rea.

2. Intention

Salmond: intention is “the purpose or design with which an act is done. It is the foreknowledge of the act, coupled with the desire of it, such foreknowledge and desire being the cause of the act.” An intended consequence is one that the doer both foresees and desires.

• Intention and foresight. A consequence that is foreseen as certain or virtually certain is treated as intended, even if not desired for its own sake. A man who blows up an aircraft to collect insurance on the cargo intends the death of the crew.
• Intention and expectation. A consequence may be intended though not expected, as when a man shoots at a distant target hoping, without much expectation, to hit it.
• Immediate and ulterior intent. The immediate intent relates to the act itself (to take the money); the ulterior intent to the purpose beyond (to buy food). The ulterior intent is the motive.
• Transferred intention. Where A intends to kill B but kills C by mistake, the intention is transferred (section 102 of the Bharatiya Nyaya Sanhita, 2023, formerly section 301 IPC).
• Constructive intention. In some cases the law imputes intention to a person who did not in fact have it, as in the rule that a person intends the natural consequences of his acts.

3. Motive and malice

Motive is the ulterior intent: the reason why a person intended the act. The general rule is that motive is irrelevant to liability. A bad motive does not make a lawful act unlawful (Bradford Corporation v. Pickles, 1895), and a good motive does not make an unlawful act lawful (a person who steals to feed the poor commits theft). Motive is relevant in evidence, in sentencing, and in a few wrongs where the law makes it an element: malicious prosecution, conspiracy to injure, and defamation where qualified privilege is pleaded.

Malice has two meanings:

• malice in law: a wrongful act done intentionally without just cause or excuse, which is simply intention;
• malice in fact: an improper motive, spite or ill will. Only in the wrongs listed above does malice in fact matter.

4. Negligence

There are two views.

• Subjective theory (Salmond, Austin): negligence is a state of mind, “culpable carelessness”, an attitude of indifference to the consequences of one’s conduct. It is the second form of mens rea. Salmond: negligence is the state of mind of a person who does not desire the consequence but is indifferent to it.
• Objective theory (Pollock, Clerk and Lindsell, modern law): negligence is conduct, not a state of mind. It is the failure to take the care that a reasonable person would take in the circumstances, judged by an external standard, regardless of what the defendant thought. This is the view of the law of tort: Blyth v. Birmingham Waterworks Co. (1856).

In tort, negligence is also an independent wrong with three elements: duty, breach and damage (Donoghue v. Stevenson, 1932). In criminal law it must be of a higher degree. In Jacob Mathew v. State of Punjab, 2005 INSC 334, (2005) 6 SCC 1, the Supreme Court held that for criminal liability the negligence must be gross or reckless, a higher degree than suffices in civil cases. Causing death by a rash or negligent act is an offence under section 106 of the Bharatiya Nyaya Sanhita, 2023 (formerly section 304A IPC).

5. Recklessness

Recklessness lies between intention and negligence. The reckless person foresees the consequence as possible, does not desire it, and goes ahead regardless, taking an unjustified risk. The negligent person, on the subjective view, does not even consider the risk. Indian criminal law uses the word “rash” for this state: a rash act is done with awareness of the risk and indifference to it; a negligent act is done without the care that ought to have been taken. Both are covered by section 106.

6. When mens rea is excluded

A statute may create an offence of strict liability, either expressly or by necessary implication from its object. The presumption is that mens rea is required, but it is displaced in regulatory and public welfare offences: food adulteration, weights and measures, revenue and foreign exchange law. In State of Maharashtra v. Mayer Hans George, 1964 INSC 176, AIR 1965 SC 722, a German passenger who carried gold through India in transit, in breach of a notification he did not know of, was held guilty; the object of the foreign exchange law required that mens rea be excluded. Strict liability is taken up in the next note.

How this is examined

As short notes: “Mens rea” and “Intention” (June 2025, Q.5(b)); “Negligence” (January 2026, Q.9(b), 10 marks; February 2025, Q.5(b)). For mens rea, give the maxim, Salmond’s two forms, the Indian method of stating the mental element in each offence, and the exclusion in Mayer Hans George. For negligence, give the two theories, the tort elements, and Jacob Mathew on criminal negligence.
