Crime as a Legal Wrong: The Elements of an Offence

An omission counts only where the law imposes a duty to act. A stranger who watches a child drown commits no offence by walking away. A lifeguard employed to watch that pool does, because the employment creates the duty. This is why an omission case always begins by identifying the duty rather than the failure.

The act must also be voluntary. Conduct during a fit, a reflex, or while asleep is not the accused's act at all in the sense the law requires.

Element two: the guilty mind

Mens rea means the guilty mind. English law states it as a general requirement; Indian law does not, and this catches students out.

The Sanhita, like the Penal Code before it, writes the required mental state into each offence rather than laying down a general rule. So the words to look for are in the definition of the particular offence: "intentionally", "knowingly", "dishonestly", "fraudulently", "voluntarily", "rashly", "negligently", "with intent to", "having reason to believe". Each is a different mental state and each has been the subject of its own case law.

There are four broad levels, and they descend in gravity.

1. Intention. The accused meant to bring about the result. This is the highest and it is what the gravest offences require.
2. Knowledge. The accused did not necessarily want the result but knew it was likely to follow. Much of the law of homicide turns on the line between this and intention.
3. Recklessness or rashness. The accused took an unjustified risk, conscious that a risk existed.
4. Negligence. The accused fell below the standard of care a reasonable person would have observed, whether or not the accused adverted to the risk at all.

Strict liability offences require no mental element as to one or more parts of the actus reus. They are common in regulatory statutes: food adulteration, drugs, weights and measures, environmental discharge. They exist because proving the mental state of a company would otherwise make enforcement impossible, and they matter to this paper because they are the form in which the law usually reaches the powerful. Their price is that a person can be convicted without moral fault.

Element three: a person the law holds responsible

Not everyone who does the act with the mind is answerable, and the Sanhita says so in the general exceptions.

Section 20: nothing is an offence which is done by a child under seven years of age. This is absolute. It is called doli incapax, incapable of crime, and no evidence of understanding can displace it.

Section 21: nothing is an offence which is done by a child above seven and under twelve who has not attained sufficient maturity of understanding to judge of the nature and consequences of his conduct on that occasion. Here the incapacity is a presumption that can be rebutted, and note the words "on that occasion": maturity is judged act by act, not once and for all.

Section 22: nothing is an offence which is done by a person who at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law. The test is cognitive. A person who knows exactly what he is doing and knows it is wrong is not excused however disordered he is, which is a point of standing criticism dealt with later in this book.

Section 23: the same formula for involuntary intoxication, where the thing that intoxicated the accused was administered without his knowledge or against his will.

Element four: prohibition and punishment

The last element is the one that separates crime from every other kind of wrong. Somewhere there must be a provision of law that forbids the conduct and attaches a punishment to it, and the punishment must be one the State inflicts.

This is the element that makes the formal definition circular, and it is also the element that makes the criminal law an instrument of policy. Parliament decides what goes on the list. That decision is a criminological decision dressed as a legislative one.

A worked example

Sunita Kadam, aged eleven, takes a bottle of kerosene from a neighbour's kitchen and pours it on a stray dog, which is badly burned. Her uncle Dattatray, aged forty, watched her do it and said nothing.

Sunita's position. The act and the mental state are both present. But she is above seven and under twelve, so section 21 applies and the prosecution must prove that she had attained sufficient maturity of understanding to judge the nature and consequences of her conduct on that occasion. Evidence that she hid the bottle afterwards would tend to establish that maturity; evidence that she thought the kerosene was water would defeat it. If the presumption is not rebutted, there is no offence at all.

Dattatray's position. He did nothing. To convict him of an offence by omission there must be a legal duty to act, and no general duty to prevent cruelty by a bystander exists. If, however, he was the child's guardian at the time, the analysis changes, because the law recognises a duty in a person who has charge of a child. Notice that the argument turns entirely on the duty and not at all on whether we think he behaved badly.

And the criminological point. The harm is the same in both branches. Whether it becomes a crime depends on age, on maturity and on the existence of a duty, none of which has anything to do with the injury to the dog. That is the filter at work.

What beginners get wrong

Mens rea is not motive. Motive is the reason a person acted; intention is the aim with which the act was done. A man who steals bread to feed his child has an excellent motive and a complete intention to steal. Motive goes to sentence and to proof; it is not an element.

Mens rea is not a single thing. There is no general Indian requirement of "a guilty mind". There is the particular mental state named in the particular section, and an answer that says "mens rea was present" without naming which one has not done the work.

A general exception is not a defence in the loose sense. Section 20 does not mean the child is excused; it means no offence has been committed at all.

Quick revision

• Actus non facit reum nisi mens sit rea: an act does not make a person guilty unless the mind is guilty.
• Four elements: a human act or omission, the required mental state, a responsible person, and a law that prohibits and punishes.
• Actus reus covers conduct, circumstances and, where required, result. An omission counts only where there is a legal duty.
• Indian law puts mens rea in each section: intentionally, knowingly, dishonestly, fraudulently, voluntarily, rashly, negligently.
• Four levels: intention, knowledge, recklessness or rashness, negligence. Strict liability dispenses with the mental element and is the usual form of regulatory crime.
• Sanhita section 2(24): "offence" means a thing made punishable by this Sanhita.
• Sections 20 to 23: child under seven; child of seven to twelve without sufficient maturity on that occasion; unsoundness of mind making the accused incapable of knowing the nature of the act or that it is wrong or contrary to law; involuntary intoxication.

Test yourself

1. State the four elements of a crime. A human act or omission; the mental state the particular offence requires; a person whom the law holds capable of responsibility; and a legal provision prohibiting the conduct and prescribing a punishment inflicted by the State.

2. How does Indian law state the requirement of a guilty mind, and why does that matter? It does not state it generally. Each offence names its own mental element in its own words, so the correct question is never "was there mens rea" but "was there the intention, knowledge, dishonesty or rashness that this section requires". It matters because an answer pitched at the general level cannot resolve any real problem.

3. A twelve-year-old and a six-year-old together break a shop window. Discuss. The six-year-old commits no offence at all: section 20 of the Sanhita is absolute for a child under seven. The twelve-year-old is outside section 21 altogether, which covers only a child above seven and under twelve, so ordinary principles apply and the ordinary elements must be proved, subject to the separate scheme of the juvenile justice legislation governing how such a child is dealt with.

4. Why does strict liability matter to a criminology paper? Because it is the form in which the criminal law usually reaches corporate and regulatory wrongdoing. Where a mental element cannot be proved against an organisation, the legislature drops it. The gain is enforceability; the cost is conviction without moral fault, and the pattern of which harms get the strict liability treatment is itself a criminological question.
