Introduction: Why Section 17 BNS Matters
Imagine you are walking home late at night through a dark alley. Suddenly, you see a shadowy figure lunging toward you with what looks like a knife. In sheer terror, you grab a nearby stick and strike the person with all your strength. The figure falls. Moments later, you realize with horror that it was your neighbour's teenage son playing a prank with a toy gun. He is seriously injured. Should you be sent to prison for causing grievous hurt? Should you be charged with attempt to murder? The law says NO — if you genuinely believed, in good faith, that you were defending yourself against a deadly attack. This is the essence of Section 17 of the Bharatiya Nyaya Sanhita (BNS), 2023.
Section 17 is one of the most important general exceptions in India's new criminal law. It protects people who commit acts that would otherwise be crimes, but who do so either because the law actually justifies their action, or because they genuinely believe — due to a mistake of fact — that the law justifies their action. It is a shield for the honest, the mistaken, and the well-intentioned. Without this provision, every honest mistake that causes harm could become a criminal offence, and the criminal justice system would be flooded with cases of people who never meant to do anything wrong.
This provision replaced the old Section 79 of the Indian Penal Code (IPC), 1860, which had served India for over 160 years. The BNS, which came into force on 1st July 2024, retained the substance of Section 79 but gave it a new number and placed it within a modernized framework. Understanding Section 17 is essential not just for law students and lawyers, but for every citizen who wants to know when the law will forgive an honest mistake and when it will not.
In this article, we will explore every aspect of Section 17 BNS in plain, simple language. We will look at its legal text, break down its essential elements, examine landmark judgments that have shaped its interpretation, compare it with the old IPC provision, and provide a practical guide for anyone who needs to use this defence in court. Whether you are preparing for judiciary exams, handling a criminal case, or simply curious about how Indian law treats honest mistakes, this guide is for you.
What Exactly is Section 17 BNS?
Section 17 of the Bharatiya Nyaya Sanhita, 2023 falls under Chapter III — General Exceptions. General exceptions are provisions that excuse certain acts from being treated as crimes, even though those acts would normally satisfy all the ingredients of a criminal offence. They are based on the fundamental principle of criminal law that "actus non facit reum nisi mens sit rea" — an act does not make a person guilty unless their mind is also guilty.
Section 17 specifically deals with two situations:
- Acts Actually Justified by Law: When a person does something that the law explicitly permits or commands. For example, a police officer arresting a suspect under a valid warrant, or a citizen apprehending a thief under the power given by law.
- Acts Believed to be Justified by Law Due to Mistake of Fact: When a person does something believing, in good faith and due to a mistake of fact (not law), that the law justifies their action. For example, a person who shoots at what they honestly believe is a dangerous animal attacking their cattle, but which turns out to be a human being.
The key philosophy behind this section is that criminal liability requires both a guilty act (actus reus) and a guilty mind (mens rea). If a person lacks the guilty mind because they genuinely believed their act was lawful, the law should not punish them. This is not a loophole for criminals. It is a safeguard for honest people who find themselves in difficult situations where they must make split-second decisions based on limited information.
Section 17 is closely related to other general exceptions in the BNS, particularly Section 14 (act done by a person bound by law), Section 15 (act of a judge acting judicially), and Section 16 (act done pursuant to a court order). Together, these sections ensure that people acting under lawful authority or honest belief are not unjustly prosecuted.
The Complete Legal Text of Section 17 BNS
Let us look at the exact words of the law. The text of Section 17 BNS is short but packed with legal meaning. Here is the complete provision as it appears in the Bharatiya Nyaya Sanhita, 2023:
Nothing is an offence which is done by any person who is justified by law, 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 justified by law, in doing it.
Illustration:
A sees Z commit what appears to A to be a murder. A, in the exercise, to the best of his judgment exerted in good faith, of the power which the law gives to all persons of apprehending murderers in the fact, seizes Z, in order to bring Z before the proper authorities. A has committed no offence, though it may turn out that Z was acting in self-defence.
This text may look simple, but every word has been carefully chosen and intensely debated in courts for over a century. Let us now unpack each part in detail.
Key Features and Essential Elements Explained
Section 17 BNS is built around several key elements that must all be satisfied for the defence to succeed. Here is a breakdown of the most important features you need to understand:
- The Act Must Be Done by a Person: The protection applies to any person — public officer or private individual. There is no restriction based on status, profession, or position.
- Justified by Law OR Believed to Be Justified: The section covers two distinct scenarios. First, where the act is actually justified by law (e.g., a police officer making a lawful arrest). Second, where the person believes the act is justified, even if it turns out not to be.
- Mistake of Fact, Not Mistake of Law: This is the most critical element. The mistake must relate to facts (e.g., misidentifying a person, misjudging a situation), not to law (e.g., wrongly believing that assault is legal). The legal maxim "ignorantia juris non excusat" (ignorance of law is no excuse) applies here.
- Good Faith Requirement: The belief must be held in good faith. This means the person must have acted with due care and attention, not recklessly or negligently. Good faith requires both an honest belief and reasonable grounds for that belief.
- Belief Must Be About Justification by Law: The person must believe that the law justifies their act. A belief that the act is morally right or socially acceptable is not enough. The justification must be legal, not merely ethical.
- No Offence is Committed: If all the above conditions are met, the act is completely excused from criminal liability. It is not merely a mitigating factor — it is a complete defence that leads to acquittal.
Mistake of Fact vs Mistake of Law: The Critical Difference
The single most important distinction in understanding Section 17 BNS is the difference between mistake of fact and mistake of law. This distinction has been the subject of countless court cases and legal debates. Getting it wrong can mean the difference between walking free and facing years in prison.
What is Mistake of Fact?
A mistake of fact occurs when a person misunderstands the factual circumstances of a situation. It is an error about what actually exists or happened, not about what the law says. For example:
- Believing a person is a thief when they are actually an innocent passerby
- Thinking an object is a dangerous weapon when it is actually a toy
- Mistaking your own property for someone else's stolen property
- Believing a person is attacking you when they are actually trying to help you
What is Mistake of Law?
A mistake of law occurs when a person is ignorant of or misunderstands the law itself. For example:
- Believing that it is legal to carry a knife in public
- Thinking that verbal abuse is not a crime
- Assuming that you can use force to recover your debt
- Believing that ignorance of a new law is a valid defence
Why the Law Makes This Distinction
The legal maxim "ignorantia juris non excusat" (ignorance of the law is no excuse) is one of the oldest and most fundamental principles of criminal law. It means that every person is presumed to know the law of the land, and cannot escape liability by claiming they did not know their act was illegal. If this were allowed, every criminal could simply claim ignorance and walk free.
On the other hand, "ignorantia facti excusat" (ignorance of fact is an excuse) recognizes that people cannot be expected to know every factual detail of every situation. If an honest and reasonable mistake about facts leads a person to believe their act is lawful, the law forgives them. This balance ensures that the law is neither too harsh nor too lenient.
Good Faith: The Heart of Section 17 BNS
The concept of good faith is the beating heart of Section 17 BNS. Without good faith, the defence collapses. But what exactly does "good faith" mean in law? It is not merely being nice or well-intentioned. It has a specific legal meaning that has been refined by decades of judicial interpretation.
Under Section 14(3) of the BNS, "nothing is said to be done or believed in good faith which is done or believed without due care and attention." This means good faith has two components:
- Subjective Honesty: The person must genuinely and honestly believe in the facts as they perceive them. There must be no deceit, no pretence, and no hidden motive.
- Objective Reasonableness: The belief must be based on reasonable grounds. A completely baseless, fanciful, or absurd belief does not qualify as good faith, even if honestly held. The person must have exercised due care and attention before acting.
The Supreme Court, in the landmark case of State of Orissa v. Bhagaban Barik, laid down the test for good faith under Section 17 BNS (then Section 79 IPC). The Court held that good faith requires "not logical infallibility but due care and attention." This means a person does not need to be absolutely correct in their assessment. They only need to have acted with the care and attention that a reasonable person would exercise in the same circumstances.
For example, if a person sees someone breaking into their neighbour's house at night and apprehends them, believing them to be a thief, their belief is reasonable even if it later turns out that the person was the neighbour's estranged son who had lost his keys. The apprehender acted with due care based on the visible facts. But if the same person attacks a delivery person in broad daylight without any reason to suspect theft, their belief would not be reasonable, and good faith would not be established.
How Section 17 BNS Differs from Old Section 79 IPC
To truly appreciate Section 17 BNS, we must compare it with its predecessor, Section 79 of the IPC, 1860. The IPC provision had served India for over 160 years and was one of the most frequently cited general exceptions in criminal trials. The BNS retained the substance of Section 79 but made important changes in presentation and context.
- Section Number Change: Section 79 IPC became Section 17 BNS. This renumbering is part of the BNS's overall restructuring, which reduced 511 IPC sections to 358 BNS sections.
- Chapter Placement: Section 79 IPC was in Chapter IV (General Exceptions). Section 17 BNS is in Chapter III (General Exceptions). The content and structure remain the same.
- Modernized Language: The BNS uses clearer, more contemporary language while retaining the legal meaning. The phrase "believes himself to be justified by law" remains unchanged because it has been judicially interpreted for over a century.
- No Substantive Change: Importantly, there is NO change in the substantive law. All judicial precedents developed under Section 79 IPC remain fully applicable and persuasive under Section 17 BNS. Courts continue to rely on old IPC cases to interpret the new provision.
- Illustration Retained: The famous illustration about A seeing Z commit what appears to be murder and apprehending him — which was part of Section 79 IPC — has been retained in Section 17 BNS. This ensures continuity in legal education and practice.
The retention of judicial precedents is particularly important. Since the BNS came into force only on 1st July 2024, there are very few BNS-specific judgments so far. Lawyers and courts must therefore rely heavily on IPC precedents to interpret Section 17 BNS. This is explicitly recognized in the BNS's repealing and savings clause, which preserves the applicability of past judicial interpretations.
Landmark Supreme Court and High Court Judgments
The interpretation of Section 17 BNS (and its predecessor Section 79 IPC) has been shaped by some of the most fascinating and consequential cases in Indian criminal law. These cases illustrate how courts apply the principles of mistake of fact and good faith in real-life situations. Let us examine the most important ones.
Chirangi v. State: The Tiger That Changed Criminal Law
Perhaps no case better illustrates the power of Section 17 BNS (then Section 79 IPC) than Chirangi v. State of Madhya Pradesh (1952). This case is legendary in Indian legal circles and is taught in virtually every law school in the country.
The Facts
Chirangi Lohar was a 45-year-old widower living in Bastar district with his unmarried daughter, his 12-year-old son Ghudsai, and his nephew Khotla. Their relations were cordial. Chirangi had an abscess in his leg and suffered from bilateral cataract, which affected his vision. One afternoon, Chirangi took an axe and went with his son Ghudsai to a nearby hillock called Budra Meta to gather 'siadi' leaves. In the evening, Ghudsai was nowhere to be found. Chirangi was found asleep with a blood-stained axe beside him. When questioned, he said: "I had become insane. I have killed my son in Budra Meta. It occurred to me that a tiger had come to me. I then dealt blows with the axe."
The body of Ghudsai was found on the hillock. The autopsy showed incised wounds on the right temple, neck, and left humerus, with a comminuted fracture of the right temporal bone. Chirangi also had injuries, which he explained by saying he had fallen on a stone and that because of madness he did not know what had happened.
The Trial and Appeal
The trial court convicted Chirangi under Section 302 IPC (murder) and sentenced him to transportation for life. The court held that there was no mistake of fact and that even if there was, it was not in good faith. Chirangi appealed to the Bombay High Court.
The High Court invited Dr. K.C. Dube, a psychiatrist from Nagpur, to examine the medical evidence. Dr. Dube testified that:
- Chirangi's bilateral cataract made it possible for him to genuinely mistake his son for a tiger
- The abscess in his leg would have produced a fever that could cause temporary delirium
- He probably suffered from cardiovascular disease that could cause temporary confusion
- The injury to his eyebrow could have caused a state of concussion
The four assessors were unanimously of the opinion that Chirangi had actually mistaken his son for a tiger and acted under a bona fide mistake of fact in a fit of temporary insanity.
The High Court's Decision
The Bombay High Court set aside the conviction and acquitted Chirangi. The Court held that Chirangi, by reason of mistake of fact, believed himself to be justified in destroying what he thought was a dangerous animal, not a human being. Since he genuinely believed the object of his attack was a tiger and not his son, he lacked the mens rea (criminal intent) necessary for murder. The Court applied Section 79 IPC (now Section 17 BNS) and held that the act was protected.
The Court also referred to two earlier cases with similar facts — Waryam Singh v. Emperor (1926), where the accused killed a man believing him to be a ghost, and Bonda Kui v. Emperor (1943), where the accused killed someone believing them to be a man-eating demon. In both cases, the courts had held that the absence of mens rea due to a genuine mistake of fact justified acquittal under Section 79 IPC.
State of Orissa v. Bhagaban Barik: When Good Faith is Missing
While Chirangi shows when Section 17 BNS applies, State of Orissa v. Bhagaban Barik (AIR 1987 SC 1265) shows when it does NOT apply. This Supreme Court judgment is equally important for understanding the limits of the defence.
The Facts
Bhagaban Barik and the deceased had strained relations over grazing of cattle. One evening, the deceased had gone to a neighbour's house for a religious recital (Bhagbat). Several villagers, including Bhagaban, were also present. At about 10 p.m., the recital ended and the deceased returned home. Shortly after, a hue and cry was raised near Bhagaban's house. Villagers ran to the spot and found the deceased lying on the ground in a pool of blood with a severe head injury. Bhagaban, along with his mother and wife, was tending to the deceased.
The deceased, while still conscious, told villagers that Bhagaban had assaulted him. Bhagaban's defence was that during the day, his bell-metal utensils had been stolen, and he was keeping watch for the thief. He claimed he saw a person near his premises, asked who it was, received no response, and believing the person to be a thief, dealt a lathi blow. He later discovered it was the deceased.
The Trial and High Court
The Sessions Judge convicted Bhagaban under Section 304 Part II IPC (culpable homicide not amounting to murder) and sentenced him to rigorous imprisonment. However, the Orissa High Court acquitted him, holding that he was protected under Section 79 IPC (now Section 17 BNS) because he had acted under a mistake of fact in good faith.
The Supreme Court's Reversal
The State of Orissa appealed to the Supreme Court. A bench of Justices A.P. Sen and V. Balakrishna Eradi allowed the appeal, set aside the acquittal, and convicted Bhagaban. The Court held that the High Court's judgment was "apparently erroneous and has caused manifest miscarriage of justice."
The Supreme Court explained the law on Section 17 BNS (then Section 79 IPC) in detail:
- Good Faith Requires Due Care: "Nothing is said to be done or believed in good faith which is done or believed without due care and attention." The question of good faith must be considered with reference to the position of the accused and the circumstances under which he acted.
- Mistake Must Be Reasonable: The Court held that the alleged offender is deemed to have acted under that state of things which he in good faith and on reasonable grounds believed to exist. But the belief must be reasonable, not fanciful.
- Complete Absence of Good Faith: In Bhagaban's case, there was complete absence of good faith. The deceased and Bhagaban had strained relations. The deceased had not entered Bhagaban's house or even come near it. He was simply returning from a religious function. Bhagaban had stealthily followed him and struck him with great force on the head — a vulnerable part of the body. There was no suggestion that he acted in self-defence.
- Conviction Restored: The Supreme Court convicted Bhagaban under Section 304 Part II IPC and sentenced him to three years of rigorous imprisonment.
Raj Kapoor v. Laxman: Censorship and Justified Acts
Not all Section 17 BNS cases involve violence or death. The defence also applies in civil and regulatory contexts. A famous example is Raj Kapoor v. Laxman (1980), which involved the film industry and the Cinematograph Act.
Raj Kapoor, the legendary film producer, was accused under Section 292 IPC (obscenity) for showing allegedly obscene content in his film "Satyam Shivam Sundaram." The film had received an 'A' (Adults Only) certificate from the Central Board of Film Censors under Section 5(A) of the Cinematograph Act, 1952.
Raj Kapoor claimed protection under Section 79 IPC (now Section 17 BNS). He argued that he believed in good faith that his act was justified by law because the film had been lawfully certified by a competent statutory authority after due scrutiny. The Supreme Court agreed. It held that since the film had been certified by the Board of Censors — a body established by law with the specific power to approve films — Raj Kapoor's belief that his act was lawful was reasonable and justified. The Court quashed the proceedings against him.
This case established an important principle: when a statutory authority lawfully approves an act, the person relying on that approval is protected under Section 17 BNS, even if the approval is later found to be questionable. The certification under a special law (Cinematograph Act) overrides general criminal provisions (IPC obscenity law).
Section 17 BNS and Private Defence
One of the most common situations where Section 17 BNS applies is in cases involving the right of private defence. The BNS devotes an entire sub-chapter (Sections 34 to 44) to the right of private defence of body and property. Section 17 BNS often works alongside these provisions.
The right of private defence allows a person to use reasonable force to protect themselves, others, or their property from unlawful aggression. However, this right is limited by several conditions:
- Reasonable Apprehension: The person must have a reasonable apprehension of danger, not a vague or imaginary fear.
- Proportionate Force: The force used must be proportionate to the threat. You cannot shoot someone for slapping you.
- No Time for Public Help: The right exists only when there is no time to seek help from public authorities like the police.
- Not Against Public Servants: The right generally does not extend to acts done by public servants in good faith under colour of their office.
Section 17 BNS becomes relevant when a person mistakenly believes they are exercising their right of private defence. For example:
- A person sees someone approaching them at night with a stick and believes they are about to be assaulted. They strike back and seriously injure the person, who turns out to be a night watchman making rounds. If the belief was honest and based on reasonable grounds (darkness, isolated area, aggressive posture), Section 17 BNS may protect them.
- A farmer sees an animal attacking his cattle in the dark and shoots it. It turns out to be a person wearing an animal costume for a festival. If the farmer genuinely believed it was a dangerous animal and had no reason to think otherwise, Section 17 BNS applies.
However, if the mistake is unreasonable — for example, shooting at a clearly identifiable person in broad daylight — the defence will fail. The courts apply a dual test: the belief must be both subjectively genuine and objectively reasonable.
Protection for Public Officers Under Section 17 BNS
Section 17 BNS provides important protection for public officers who act under statutory authority. Police officers, magistrates, revenue officials, and other government servants often have to take actions that would otherwise be crimes — making arrests, conducting searches, seizing property, using force to disperse unlawful assemblies. Section 17 BNS ensures that these officers are protected when they act within their lawful authority.
In State of West Bengal v. Shew Mangal Singh (1982), the Supreme Court upheld that an officer acting under a lawful order, even if that order results in harm, is not committing an offence. The Court emphasized that compliance with lawful authority is a defence against liability.
However, the protection is not absolute. Public officers must act:
- Within their legal authority: An officer cannot exceed the powers granted by law and then claim protection.
- In good faith: The officer must genuinely believe they are acting lawfully and must exercise due care.
- Without malice: The act must not be motivated by personal vendetta, corruption, or ulterior motives.
In State of Orissa v. Bhagaban Barik, the Supreme Court clarified that even public officers cannot claim protection if they act without good faith. The fact that a person holds a position of authority does not automatically entitle them to the benefit of Section 17 BNS. The court will examine the circumstances objectively.
Practical Guide for Lawyers and Accused Persons
If you are a lawyer defending a client under Section 17 BNS, or an accused person seeking to avail this defence, here is a practical step-by-step guide:
Step 1: Establish the Factual Mistake
- Identify the specific factual error that led to the accused's action. Was it misidentification of a person? Misjudgment of a situation? Misunderstanding of an object's nature?
- Gather evidence supporting the mistake — medical reports (vision problems, mental state), witness testimony about lighting and visibility, expert opinions on perception.
- Show that the mistake was about facts, not law. The accused must have been wrong about what existed or happened, not about what the law permits.
Step 2: Prove Good Faith
- Demonstrate that the accused honestly believed in the mistaken facts. This can be shown through their immediate statements after the incident, their conduct, and their relationship with the victim.
- Show that the belief was reasonable under the circumstances. What would an ordinary, prudent person have believed in the same situation?
- Highlight any physical or mental conditions that affected the accused's perception — poor eyesight, fever, concussion, darkness, noise, sudden shock.
Step 3: Distinguish from Mistake of Law
- Ensure the defence is NOT based on ignorance of law. If the accused claims they did not know assault was illegal, the defence will fail immediately.
- Frame the defence around factual circumstances — what the accused saw, heard, or perceived — not around legal knowledge.
Step 4: Address the Burden of Proof
- Under Indian criminal law, the burden of proving a general exception lies on the accused. However, the accused only needs to establish their defence on a preponderance of probabilities (more likely than not), not beyond reasonable doubt.
- The accused can establish the defence either by adducing independent evidence or by cross-examining prosecution witnesses to create reasonable doubt.
Step 5: Cite Relevant Precedents
- Use Chirangi v. State for cases involving misidentification or delusion.
- Use State of Orissa v. Bhagaban Barik to show the limits of the defence — when good faith is absent.
- Use Raj Kapoor v. Laxman for cases involving statutory authorisation or certification.
Limitations and Grey Areas of Section 17 BNS
Despite its importance, Section 17 BNS has several limitations and grey areas that lawyers and courts continue to grapple with:
- The "Reasonable Belief" Standard: What constitutes a "reasonable" belief is inherently subjective. Different judges may have different views on what an ordinary person would have believed in the same circumstances. This leads to inconsistent outcomes.
- Mistake vs. Negligence: The line between an honest mistake and negligence is thin. If a person could have avoided the mistake by exercising more care, should they still be protected? Courts have struggled with this question.
- Medical and Psychiatric Evidence: In cases like Chirangi, the defence depends heavily on medical evidence about the accused's mental state. Poor defendants often cannot afford expert psychiatric testimony, putting them at a disadvantage.
- Cultural and Superstitious Beliefs: In Chirangi and Waryam Singh, the accused believed in ghosts and tigers. Should superstitious beliefs be treated as reasonable? The courts have generally been lenient in rural contexts but stricter in urban settings.
- Excessive Force: Even if the initial mistake is genuine, if the accused uses disproportionate force, the defence may fail. For example, shooting someone who is merely trespassing would likely not be protected.
These grey areas mean that Section 17 BNS defences are highly fact-specific. No two cases are exactly alike, and the outcome depends heavily on the judge's assessment of credibility, reasonableness, and good faith.
Section 17 BNS for Judiciary and Competitive Exams
For students preparing for judiciary exams, AIBE, state public service commissions, and other competitive examinations, Section 17 BNS is a high-yield topic. Here is what you need to focus on:
- Exact Wording: Memorize the section verbatim. Examiners often ask for the exact language of general exceptions.
- Difference from Section 14 BNS: Section 14 deals with acts done by a person bound by law. Section 17 deals with acts justified by law. The difference is subtle but important — "bound" means legally compelled, while "justified" means legally permitted.
- Landmark Cases: Know Chirangi, Bhagaban Barik, and Raj Kapoor inside out. Be ready to distinguish them based on facts and principles.
- Mistake of Fact vs. Mistake of Law: This is the most frequently tested aspect. Be prepared to apply it to hypothetical situations.
- Good Faith Definition: Remember Section 14(3) BNS — "nothing is said to be done or believed in good faith which is done or believed without due care and attention."
- Illustration: The illustration to Section 17 BNS (A sees Z commit what appears to be murder) is often directly asked in exams.
Conclusion: Justice for the Honest Mistake
Section 17 of the Bharatiya Nyaya Sanhita, 2023 is a testament to the wisdom of Indian criminal law. It recognizes that human beings are fallible, that perception can be flawed, and that honest mistakes should not be punished as crimes. In a world where the criminal justice system is often criticized for being harsh and unforgiving, Section 17 stands as a reminder that justice must be tempered with mercy and reason.
The section protects the police officer who makes a lawful arrest, the citizen who apprehends a criminal in the act, the farmer who defends his cattle from what he believes is a wild animal, and the filmmaker who relies on lawful certification. But it also draws a clear line. It does not protect those who act out of malice, who use excessive force, or who recklessly disregard the safety of others. The requirement of good faith ensures that the defence is available only to the truly innocent, not to those seeking to escape accountability.
As India's criminal law evolves under the BNS, Section 17 remains one of the most important tools for ensuring that justice is done — not just to victims of crime, but also to those who, through no fault of their own, find themselves on the wrong side of the law due to an honest mistake. For lawyers, students, and citizens alike, understanding this provision is not just an academic exercise. It is an essential part of understanding what justice truly means in a free and fair society.
The message of Section 17 BNS is simple yet profound: The law forgives an honest mistake, but it does not forgive carelessness, malice, or wilful blindness. In every case where this defence is raised, the court must ask not just what the accused believed, but whether a reasonable person in their position would have believed the same. That is the essence of justice under Section 17 BNS.
