About this topic
Every criminal case asks two questions: what did the accused do, and what was going on in the accused's mind when doing it? The doing is called actus reus (the guilty act). The thinking is called mens rea (the guilty mind).
These notes cover both elements under the B.N.S. (2023): what counts as an act and an illegal omission, the different kinds of guilty mind, how the B.N.S. writes the mental element into its definitions, the difference between intention and motive, strict liability in criminal law, and liability without fault in the civil law of torts.
Three problems to keep in mind
The following three problems are decided at the end of these notes, once the principles below are in place.
The pool: A child is drowning in a hotel swimming pool. Two people see it happen. One is Prince, the lifeguard the hotel has hired to watch that pool. The other is Neha, a guest resting on a deckchair. Neither of them moves, and the child dies. Has either of them committed an offence?
The plane: A foreign traveller is flying across the world. His plane touches down briefly in India, and he never steps off it. Three days before his journey began, India added a new condition about what transit passengers must declare. He had no idea. Can he be punished for breaking a rule he had never heard of?
The bank: Zoya, a bank clerk, quietly moves money out of a wealthy customer's dormant account to pay for a poor child's heart surgery. She keeps nothing for herself. Her heart is pure. Is she a criminal?
The two elements of a crime
The act and the mind meet in an old maxim: actus non facit reum nisi mens sit rea.
Actus non facit reum nisi mens sit rea: an act does not make a person guilty unless his mind is also guilty. Actus reus = the guilty act. Mens rea = the guilty mind.
The two-key locker. Think of a bank locker that opens only when two keys are turned together. One key is the act; the other key is the mind. In the ordinary case, the door to punishment opens only when both keys turn at the same moment. A few special lockers are built to open with a single key (offences where the legislature has done without the guilty mind; see strict liability below).
The main statute for this topic is the B.N.S. (2023).
Actus reus: the guilty act
Actus reus is the outward, physical side of an offence. It is the conduct that the law forbids, together with any circumstances and consequences that the definition of the offence requires.
- Murder: the actus reus is conduct that causes the death of a human being.
- Theft: the actus reus is moving someone's movable property out of his possession without his consent.
The conduct must come from the person's own will
The law does not blame a person for a movement that his will did not direct at all.
Renu is standing in a packed metro coach. She suddenly faints, and as she falls, her elbow smashes another passenger's spectacles and cuts his face. Her body caused the injury, but nothing travelled from her will to her arm. She is not blamed for the movement.
An act includes a series of acts: Section 2(1)
An act is not always a single movement. Section 2(1) of the B.N.S. says:
"'act' denotes as well a series of acts as a single act"
Farhan, a cashier, slips a 200-rupee note out of the cash drawer every evening for a whole year. Any one evening looks small. The definition lets the law see the whole chain of conduct as one act.
Actus reus can be a failure to act: omissions
Actus reus includes an omission (a failure to act). This point is often missed in answers.
- Section 2(25): "'omission' denotes as well as a series of omissions as a single omission" (this is the wording exactly as printed in the official text).
- Section 3(4): "In every Part of this Sanhita, except where a contrary intention appears from the context, words which refer to acts done extend also to illegal omissions."
Only an illegal omission counts: Section 2(15)
The word illegal matters: not every failure to act counts. Section 2(15) explains:
"The word 'illegal' is applicable to everything which is an offence or which is prohibited by law, or which furnishes ground for a civil action; and a person is said to be 'legally bound to do' whatever it is illegal in him to omit"
A failure to act becomes an illegal omission when the person was under a legal duty to act. The duty may come from:
- a statute; or
- a legally binding relationship, such as a contract of employment, because breaking that duty furnishes ground for a civil action.
A failure to act without such a legal duty is not an illegal omission.
Mens rea: the guilty mind
Mens rea is not one single state of mind. It is a family of mental states, and each offence chooses the member it wants.
Four minds, one flowerpot
The whole family can be seen through one object and four different minds. The object is a heavy clay flowerpot on a fourth-floor balcony. The man on the balcony is Aadil.
1. Intention
The result is the person's purpose.
Aadil hates his landlord, Prince. He waits until Prince walks below, takes aim, and drops the pot on his head. He wants Prince hurt or dead. That is intention.
2. Knowledge
The person foresees the result as likely, even though it is not his goal.
Aadil is furious with his whole housing society. During a crowded festival procession, he hurls pots onto the packed street below. He is not aiming at anyone, but he knows that, in such a crowd, someone is almost certain to be struck. That is knowledge.
An illustration to Section 101 of the B.N.S. shows this very mind: a person who, without any excuse, fires a loaded cannon into a crowd and kills one of them is guilty of murder, though he may have had no premeditated design to kill any particular individual.
3. Recklessness (rashness)
The person saw the risk and chose to run it. The statutes usually describe recklessness with the word rash.
A storm is coming. The neighbours shout at Aadil to bring the pots in from the narrow parapet. He knows the wind could knock one down, but he shrugs and goes back to his television. A pot falls and hits a delivery boy. That is recklessness.
4. Negligence
A failure to take the care a reasonable person would take. The thought of danger never enters the person's head.
On a calm morning, Aadil waters his plants and leaves a pot on the very edge of the railing. The thought of danger never enters his head, though any careful person would have pushed it back. A passing cat brushes it off, and it hits a woman below. That is negligence.
The ladder of blameworthiness
| Mental state | Person's relation to the harm | Blameworthiness |
|---|---|---|
| Intention | The result is his purpose; he chose the harm | Most blameworthy |
| Knowledge | Foresees the result as likely, though it is not his goal | Lower |
| Recklessness (rashness) | Saw the risk and chose to run it | Lower still |
| Negligence | Simply failed to think; did not take the care a reasonable person would take | Least blameworthy |
Moving down from intention to negligence, the person's connection with the harm grows weaker. The one who chose the harm is the most blameworthy; the one who simply failed to think is the least.
"Voluntarily": Section 2(33)
The B.N.S. has one word that gathers the top of this ladder together. Section 2(33) says:
"A person is said to cause an effect 'voluntarily' when he causes it by means whereby he intended to cause it, or by means which, at the time of employing those means, he knew or had reason to believe to be likely to cause it."
Reason to believe, Section 2(29): "A person is said to have 'reason to believe' a thing, if he has sufficient cause to believe that thing but not otherwise".
In the B.N.S., voluntarily covers intention, knowledge and reason to believe.
The illustration under Section 2(33): a man sets fire to an inhabited house at night to make a robbery easier. Even if he never intended a death, if he knew death was likely, he caused it voluntarily.
How the ladder decides an offence when someone dies
Section 100 (culpable homicide):
"Whoever causes death by doing an act with the intention of causing death, or with the intention of causing such bodily injury as is likely to cause death, or with the knowledge that he is likely by such act to cause death, commits the offence of culpable homicide."
Only the top two rungs, intention and knowledge, appear in Section 100.
- Section 101 tells when culpable homicide becomes murder. Each of its four clauses again rests on intention or knowledge.
- Section 103(1): "Whoever commits murder shall be punished with death or imprisonment for life, and shall also be liable to fine."
The bottom two rungs are handled elsewhere. Section 106(1):
"Whoever causes death of any person by doing any rash or negligent act not amounting to culpable homicide, shall be punished with imprisonment of either description for a term which may extend to five years, and shall also be liable to fine; and if such act is done by a registered medical practitioner while performing medical procedure, he shall be punished with imprisonment of either description for a term which may extend to two years, and shall also be liable to fine."
| Mental state | Provision | Punishment |
|---|---|---|
| Intention or knowledge | Culpable homicide (Section 100); murder where a clause of Section 101 applies | Murder: death or imprisonment for life, and fine (Section 103(1)) |
| Rashness or negligence | Causing death by a rash or negligent act not amounting to culpable homicide (Section 106(1)) | Up to 5 years and fine; up to 2 years and fine if done by a registered medical practitioner while performing a medical procedure |
The same flowerpot and the same death can lead either to murder or to an offence carrying at most five years. Only the mind of the person changed.
Act and mind must coincide
Both keys must turn together: the guilty mind must exist at the time of the guilty act.
Farhan is secretly planning to kill his business partner next week. Tonight, by pure accident, and without even recognising him in the dark, Farhan reverses his car into that partner, who dies. Next week's plan does not turn tonight's accident into murder, because that intention was not steering the car. Whether tonight's driving was rash or negligent is a separate question.
Where mens rea sits in the B.N.S.
The B.N.S. usually writes the mental element into the definition of the offence itself.
Mental words written into definitions
Theft, Section 303(1):
"Whoever, intending to take dishonestly any movable property out of the possession of any person without that person's consent, moves that property in order to such taking, is said to commit theft."
The mind sits in the words "intending to take dishonestly".
- Dishonestly, Section 2(7): "'dishonestly' means doing anything with the intention of causing wrongful gain to one person or wrongful loss to another person".
- Wrongful gain, Section 2(36): "'wrongful gain' means gain by unlawful means of property to which the person gaining is not legally entitled".
- Wrongful loss, Section 2(37): "'wrongful loss' means the loss by unlawful means of property to which the person losing it is legally entitled".
Cheating, Section 318, uses the words "fraudulently or dishonestly". Fraudulently, Section 2(9): "doing anything with the intention to defraud but not otherwise".
Other offences use the words voluntarily, intentionally or knowingly.
Because each definition carries its own mental element, the general doctrine of mens rea rarely needs to be imported from outside for offences under the B.N.S.
K.A. Mathai v. Kora Bibbikutty (1996), Supreme Court, decided under the old Indian Penal Code.
Facts: One of the accused bought a bus with a financier's help under a hire-purchase agreement (the buyer uses the vehicle and pays in instalments, while the financier keeps important rights until the last instalment is paid). He later sold the bus to the complainant, expressly subject to that agreement. The complainant stopped paying the instalments. On 11 November 1986, the financier took the bus back. Both accused were present, and one of them drove it away. The complainant called it theft.
Proceedings: The trial court convicted both accused of theft (then punishable under Section 379 of the Indian Penal Code) and sentenced them to one year of rigorous imprisonment and a fine. The Sessions Court acquitted them. The High Court restored the conviction. Before the Supreme Court, the accused argued that they had only exercised a right the agreements gave them.
Held: The Court agreed with the accused. A seller cannot pass on a better right than he holds, so the financier's right to resume possession had to be read into the later sale. Since the accused were asserting genuine contractual rights, there was no dishonest intention, and without it there was no theft. Both were acquitted.
Principle: Without a dishonest intention there is no theft. Today the same reasoning runs through Section 303(1) read with Section 2(7) of the B.N.S.
Definitions with no mental word: kidnapping from lawful guardianship
Some definitions contain no mental word. Students are sometimes wrongly told that whole groups of offences need no guilty mind at all.
Section 137(1)(b):
"whoever takes or entices any child or any person of unsound mind, out of the keeping of the lawful guardian of such child or person of unsound mind, without the consent of such guardian, is said to kidnap such child or person from lawful guardianship."
- Explanation: "The words 'lawful guardian' in this clause include any person lawfully entrusted with the care or custody of such child or other person."
- Child, Section 2(3): "'child' means any person below the age of eighteen years".
- No word like "dishonestly" appears.
- The child's own consent does not help the accused, because the clause asks only about the guardian's consent.
Yet the legislature did not forget the mind. It wrote its own Exception:
"This clause does not extend to the act of any person who in good faith believes himself to be the father of an illegitimate child, or who in good faith believes himself to be entitled to the lawful custody of such child, unless such act is committed for an immoral or unlawful purpose."
In kidnapping from lawful guardianship, the B.N.S. itself decides which honest beliefs count, through the Exception to Section 137(1)(b).
A presumed mind: counterfeiting, Section 2(4)
Under Section 2(4), a person is said to counterfeit "who causes one thing to resemble another thing, intending by means of that resemblance to practise deception, or knowing it to be likely that deception will thereby be practised."
- Explanation 1: the imitation need not be exact.
- Explanation 2 presumes the mind: "When a person causes one thing to resemble another thing, and the resemblance is such that a person might be deceived thereby, it shall be presumed, until the contrary is proved, that the person so causing the one thing to resemble the other thing intended by means of that resemblance to practise deception or knew it to be likely that deception would thereby be practised".
In counterfeiting, the mind remains an ingredient. The law presumes it and lets the accused prove otherwise.
Harm to the public: public nuisance, Sections 270 and 292
Public nuisance shows a third pattern: a definition that looks at harm to the public rather than at the offender's mind. Section 270:
"A person is guilty of a public nuisance who does any act or is guilty of an illegal omission which causes any common injury, danger or annoyance to the public or to the people in general who dwell or occupy property in the vicinity, or which must necessarily cause injury, obstruction, danger or annoyance to persons who may have occasion to use any public right but a common nuisance is not excused on the ground that it causes some convenience or advantage."
Prince, a hardware dealer, stacks iron rods across the public footpath every day, pushing pedestrians into traffic, and says it helps his customers. The last words of Section 270 answer him: a common nuisance is not excused on the ground that it causes some convenience or advantage.
Section 292 (where no other provision applies): "Whoever commits a public nuisance in any case not otherwise punishable by this Sanhita shall be punished with fine which may extend to one thousand rupees."
Summary: how the B.N.S. handles the mental element
| Technique | Provision | How the mind is handled |
|---|---|---|
| Mental word in the definition | Theft, Section 303(1); cheating, Section 318 | "Intending to take dishonestly"; "fraudulently or dishonestly" (also voluntarily, intentionally, knowingly in other offences) |
| No mental word, but a statutory Exception | Kidnapping from lawful guardianship, Section 137(1)(b) | The Exception protects specified good-faith beliefs, unless the act is for an immoral or unlawful purpose |
| Mind presumed | Counterfeiting, Section 2(4), Explanation 2 | Intention or knowledge presumed where the resemblance might deceive, until the contrary is proved |
| Focus on harm to the public | Public nuisance, Section 270 (punishment, Section 292) | Looks at common injury, danger or annoyance to the public rather than at the offender's mind |
Intention and motive
Intention is the immediate aim of an act. Motive is the deeper reason for wanting that aim. When deciding guilt, the law asks about intention, not motive.
Zoya, the bank clerk, intended to take money that was not hers to give. Her motive was to save a child. A noble motive cannot cancel a dishonest intention, though it may matter at sentencing.
The reverse is also true. A man who hates his neighbour and wishes every day that he would die has an ugly motive, but no act matches it, so there is no offence. The law does not punish wishes.
| Point | Intention | Motive |
|---|---|---|
| Meaning | The immediate aim of an act | The deeper reason for wanting that aim |
| Deciding guilt | The law asks about it | The law does not ask about it; a noble motive cannot cancel a dishonest intention, and a bad motive with no matching act is no offence |
| Other relevance | - | May matter at sentencing; relevant in proof (Section 6(1), B.S.A.) |
Motive in proof: Section 6(1), B.S.A.
Motive truly earns its place in proof. Section 6(1) of the B.S.A. (2023) says:
"Any fact is relevant which shows or constitutes a motive or preparation for any fact in issue or relevant fact."
An old man is found poisoned in his locked house, with no eyewitness. His nephew Aadil was about to be cut out of the will, and Aadil bought rat poison two days earlier. The first fact shows motive; the second shows preparation. Both are relevant.
In a case built on circumstantial evidence (a chain of surrounding facts), motive can be a strong link. With a reliable eyewitness, a case can stand even if the motive is never found.
Strict liability in criminal law
Some offences are special lockers that open with a single key: the legislature has chosen to do without a guilty mind. Two Supreme Court decisions, seven months apart, show when a court will and will not find this.
The foreign traveller's case
State of Maharashtra v. Mayer Hans George (1964), Supreme Court, decided on 24 August 1964. The law in question was the Foreign Exchange Regulation Act, 1947, along with the Sea Customs Act.
Facts: George, a German national, left Zurich on 27 November 1962, bound for Manila. Early next morning his plane landed at Santacruz airport in Bombay (today's Mumbai). He stayed on board. Customs officers, acting on prior information, found him wearing a jacket with 28 compartments, 19 of them holding gold slabs weighing about 34 kilograms.
The rule: Since 1948, the Reserve Bank of India had allowed gold passing through India in transit under a general permission. A new notification dated 8 November 1962, published in the Gazette of India on 24 November 1962, added a condition: such gold had to be declared in the manifest (the official list of goods an aircraft carries). George's gold was not declared.
Proceedings: The Presidency Magistrate sentenced him to one year of rigorous imprisonment. The Bombay High Court acquitted him.
Arguments: George argued that mens rea is essential, that the condition was published only three days before he left Zurich, and that the prosecution itself accepted he did not know of it. The State replied that the law protected the country's foreign exchange and fought smuggling, and would collapse if ignorance became a defence.
Held: By a majority (Justice N. Rajagopala Ayyangar, with Justice J.R. Mudholkar agreeing), the Supreme Court sided with the State. On the language of the foreign exchange law, there was no room to add any mental element beyond the voluntary act of bringing the gold into India. Publication in the Gazette in India was enough, and a foreigner's ignorance was irrelevant. The conviction was restored, though the sentence was reduced to the period already undergone.
Dissent: Justice K. Subba Rao dissented, holding that the presumption of mens rea had not been displaced.
Principle: Where the statute's language and purpose exclude mens rea, ignorance of a properly published rule is no defence.
Ignorance of the law is no excuse
Ignorantia juris non excusat: ignorance of the law is no excuse.
The B.N.S. builds this maxim into the General Exceptions:
- Section 14: "Nothing is an offence which is done by a person who is, or who by reason of a mistake of fact and not by reason of a mistake of law in good faith believes himself to be, bound by law to do it."
- Section 17 uses the same formula for a person who believes himself to be "justified by law".
- Good faith, Section 2(11): "Nothing is said to be done or believed in 'good faith' which is done or believed without due care and attention". Good faith is therefore demanding.
An honest mistake of fact can protect the accused. A mistake of law cannot.
The foodgrain dealer's case
Nathulal v. State of Madhya Pradesh (1965), Supreme Court, decided on 22 March 1965, seven months after Mayer Hans George, going the other way.
Facts: Nathulal dealt in foodgrains at Dhar, in Madhya Pradesh. A licensing order under the Essential Commodities Act, 1955 required a licence to deal in 100 maunds or more. On 30 September 1960, he applied and deposited the fee. He kept sending fortnightly returns of his purchases and sales, and no one objected. He said an Inspector assured him the licence would be sent to his home. In fact the application had been rejected, but no one told him. When about 885 maunds of wheat were found in his godown, he was prosecuted under Section 7 of the Act.
Proceedings: The trial court acquitted him. The High Court convicted him, with one year of rigorous imprisonment and a fine of 2,000 rupees.
Arguments: The State argued that a law controlling essential goods should punish the bare breach.
Held: The Supreme Court, by majority, disagreed with the State. Justice K. Subba Rao wrote: "Mens rea is an essential ingredient of a criminal offence." A statute may exclude it, but only "expressly or by necessary implication". The welfare object of a statute "is by itself not decisive", and mens rea may be excluded by necessary implication "only where it is absolutely clear that the implementation of the object of the statute would otherwise be defeated." Requiring an intentional breach would not defeat this Act. Nathulal had stored the grain under a bona fide (honest) belief that his licence had been issued, so he was acquitted.
Separate view: Justice J.C. Shah agreed that a guilty mind was required, but felt the dealer knew he held no licence. Given the officials' own negligence, he would have imposed only a 50-rupee fine.
Principle: Mens rea is presumed to be required. It is excluded only expressly or by necessary implication, and the welfare object of a statute is not by itself decisive.
The two cases side by side
| Point | State of Maharashtra v. Mayer Hans George (1964) | Nathulal v. State of Madhya Pradesh (1965) |
|---|---|---|
| Statute | Foreign Exchange Regulation Act, 1947, with the Sea Customs Act | Licensing order under the Essential Commodities Act, 1955 |
| Accused's mind | Did not know of the newly published condition | Honest belief that his licence had been issued |
| Mens rea | The statute's language and purpose shut the door on mens rea | Nothing shut that door, so the presumption of mens rea survived |
| Result | Conviction restored; sentence reduced to the period already undergone | Acquitted |
| Bench | Majority: Justice N. Rajagopala Ayyangar with Justice J.R. Mudholkar; Justice K. Subba Rao dissented | Majority opinion by Justice K. Subba Rao; Justice J.C. Shah took a separate view |
The starting point is always that a guilty mind is required. Strict liability is the exception, and a court must find it in the statute's words or unavoidable logic.
Liability without fault in civil law
Liability without fault grew up mainly in the civil law of torts, where the question is compensation, not punishment. The following two cases belong in their own box, separate from criminal liability.
Rylands v. Fletcher (English case; Justice Blackburn, 1866; affirmed by the House of Lords, 1868).
Facts: Rylands, a mill owner, had contractors build a reservoir on his land. They came across old, disused mine shafts beneath the site and did not seal them. When the reservoir was filled, water rushed down the shafts and flooded Fletcher's neighbouring coal mine. Rylands knew nothing of the shafts and argued that the fault was not his.
Held: Rylands was held liable anyway. Justice Blackburn, in 1866, explained that a person who, for his own purposes, brings onto his land and keeps there anything likely to do mischief if it escapes keeps it at his own peril, and is prima facie (at first sight) answerable for the damage that naturally follows its escape. When the House of Lords affirmed this in 1868, Lord Cairns tied the rule to a non-natural use of land.
Exceptions the rule gathered over time: an act of God; the act of a stranger; the injured person's own default; his consent; and statutory authority.
Principle: Strict liability in tort for the escape of a dangerous thing brought onto land, subject to exceptions.
M.C. Mehta v. Union of India (1986), decided on 20 December 1986 by five judges led by Chief Justice P.N. Bhagwati.
Facts: M.C. Mehta's writ petition under Article 32 sought the closure of hazardous units of Shriram Foods and Fertiliser Industries in Delhi. While it was pending, oleum gas escaped from one unit on 4 and 6 December 1985, and the Delhi Legal Aid and Advice Board and the Delhi Bar Association sought compensation for those harmed.
Issue: Was the old rule in Rylands v. Fletcher, with its exceptions, good enough for a modern hazardous industry?
Held: No. An enterprise in a hazardous or inherently dangerous activity, when harm results, is "strictly and absolutely liable to compensate all those who are affected by the accident and such liability is not subject to any of the exceptions which operate vis-a-vis the tortious principle of strict liability" under the rule in Rylands v. Fletcher. Compensation must match the "magnitude and capacity" of the enterprise, so that it deters: "The larger and more prosperous the enterprise, the greater must be the amount of compensation payable by it".
Principle: Absolute liability is strict liability with the exceptions removed.
| Point | Strict liability (Rylands v. Fletcher) | Absolute liability (M.C. Mehta v. Union of India) |
|---|---|---|
| Who is liable | A person who, for his own purposes, brings onto his land and keeps there anything likely to do mischief if it escapes (tied by Lord Cairns to a non-natural use of land) | An enterprise engaged in a hazardous or inherently dangerous activity, when harm results |
| Exceptions | Act of God, act of a stranger, the injured person's own default, his consent, statutory authority | Not subject to any of the exceptions |
| Compensation | Damage that naturally follows the escape | Must match the "magnitude and capacity" of the enterprise, so that it deters |
These tort cases share a policy with strict criminal liability: whoever creates a serious risk for others must bear the cost when it comes true, even without proof of a guilty mind.
The three problems decided
The pool
- Prince, the lifeguard, was hired to watch that pool. His failure breaks a duty that furnishes ground for a civil action, so it is an illegal omission under Section 2(15), and Section 3(4) makes it count as conduct. Which offence follows depends on his mind, from culpable homicide down to causing death by negligence.
- Neha, the guest, had no legal duty, so her silence, however troubling, is not an illegal omission.
The plane
The traveller is Mayer Hans George, and his conviction was restored. Ignorance of a properly published rule was no defence.
The bank
Zoya intended to cause wrongful loss to another person, which is exactly what dishonestly means, so offences built on dishonesty, such as criminal breach of trust, are in play. Her noble motive cannot wipe out that intention.
Quick revision
- Two elements: actus reus (the guilty act) and mens rea (the guilty mind). Actus non facit reum nisi mens sit rea: an act does not make a person guilty unless his mind is also guilty.
- Voluntary conduct: a movement that the person's will did not direct at all (for example, a fall while fainting) is not blamed.
- Act and omission: an act includes a series of acts (Section 2(1)); an omission includes a series of omissions (Section 2(25)); words referring to acts extend to illegal omissions (Section 3(4)).
- Illegal omission: only a failure to act where there was a legal duty, from a statute or a legally binding relationship such as a contract of employment (Section 2(15)).
- Ladder of minds: intention, knowledge, recklessness (rashness), negligence; blameworthiness falls as one moves down.
- "Voluntarily" (Section 2(33)): covers intention, knowledge and reason to believe ("reason to believe", Section 2(29)).
- Death cases: intention or knowledge leads to culpable homicide (Section 100) or murder (Sections 101 and 103(1)); rashness or negligence leads to Section 106(1), up to 5 years and fine (up to 2 years and fine for a registered medical practitioner performing a medical procedure).
- Coincidence: the guilty mind must exist at the time of the guilty act.
- Mind in the definition: theft (Section 303(1)) needs "intending to take dishonestly"; dishonestly (Section 2(7)) means intending wrongful gain or wrongful loss. K.A. Mathai v. Kora Bibbikutty (1996): genuine contractual rights, no dishonest intention, no theft.
- Other techniques: a statutory Exception for good-faith beliefs (kidnapping, Section 137(1)(b)); a presumed mind (counterfeiting, Section 2(4), Explanation 2); a focus on harm to the public (public nuisance, Sections 270 and 292).
- Intention v. motive: guilt turns on intention, not motive; a noble motive cannot cancel a dishonest intention, though it may matter at sentencing; the law does not punish wishes; motive and preparation are relevant facts (Section 6(1), B.S.A.).
- Strict liability in criminal law: mens rea is presumed to be required and is excluded only expressly or by necessary implication. Mayer Hans George (1964): excluded, conviction restored. Nathulal (1965): not excluded, acquitted.
- Ignorance of law: ignorantia juris non excusat; a mistake of fact in good faith can protect (Sections 14 and 17), a mistake of law cannot; good faith needs due care and attention (Section 2(11)).
- Civil law: strict liability, Rylands v. Fletcher (with exceptions); absolute liability, M.C. Mehta v. Union of India (1986) (no exceptions; compensation matched to the enterprise's magnitude and capacity).
- The three problems: the lifeguard's failure is an illegal omission and the guest's is not; the traveller's conviction was restored; the bank clerk acted dishonestly despite her noble motive.
- The two-key test for every offence in the B.N.S.:
- What act, or illegal omission, does the definition demand?
- What state of mind does it demand, or has the legislature clearly chosen to do without one?
