What Is a Cognizable and Non-Cognizable Offence Under BNSS — First Schedule Explained

When a crime happens, the first question in every police station is simple. Can the police register a case and act on their own, or do they need permission from a Magistrate first. This one question decides whether an offence is cognizable or non cognizable.

In simple words, a cognizable offence is one where the police can register an FIR, start investigation and arrest the accused without a warrant. A non cognizable offence is one where the police cannot arrest without a warrant and cannot even start investigation without the order of a Magistrate.

This classification is not found in the Bharatiya Nyaya Sanhita, 2023, which only tells us what an offence is. The classification is found in the Bharatiya Nagarik Suraksha Sanhita, 2023, popularly called BNSS, through its First Schedule. This topic is a regular favourite in the Judiciary Exam because it forms the base of the entire criminal procedure. Prelims papers test the definitions directly, Mains papers expect a proper explanation with the First Schedule and case law, and Interview panels often ask practical questions about FIR registration.

Students preparing under Nitesh Choubey Sir at Aashayein Judiciary are advised to be very clear on this topic, since almost every question on FIR, arrest and bail in the Judiciary Exam is connected to it.

What Is a Cognizable Offence

Section 2(1)(g) of the BNSS, 2023 defines a cognizable offence as an offence for which a police officer may, in accordance with the First Schedule or any other law in force, arrest a person without a warrant.

This means that the moment the police receive information about such an offence, they do not need to wait for anyone's permission. They can straightaway register an FIR under Section 173 of the BNSS, begin investigation under Section 175, and arrest the accused if required.

Suppose a person is robbed at knife point on a public road and a passerby informs the nearest police station. Since robbery is a cognizable offence, the police can register the FIR immediately and start searching for the accused without going to a Magistrate first.

Cognizable offences are generally the serious ones. Murder, rape, kidnapping, dacoity and robbery are common examples. Since these offences pose immediate danger to life, property or public order, the law gives the police the power to act fast.

What Is a Non Cognizable Offence

Section 2(1)(o) of the BNSS, 2023 defines a non cognizable offence as an offence for which a police officer has no authority to arrest without a warrant.

In such cases, the police cannot register a regular FIR on their own. They record the complaint in the Non Cognizable Register, commonly called the NC Register, and direct the complainant to approach a Magistrate. Section 174 of the BNSS deals with how the police must handle such information.

Suppose two neighbours have a quarrel over a common wall and one of them pushes the other, causing simple hurt without any weapon. This kind of minor hurt is usually treated as non cognizable. The police will note the complaint but cannot start investigation unless the Magistrate passes an order under Section 174 of the BNSS directing them to do so.

Non cognizable offences are generally less serious in nature. Simple hurt, defamation and public nuisance are common examples. Since these offences mostly arise out of private disputes, the law wants a judicial mind to look at the matter before the police use their powers of arrest and investigation.

Role of the First Schedule of the BNSS

The First Schedule to the BNSS, 2023 is a table that lists offences under the Bharatiya Nyaya Sanhita section by section. Against every section, the Schedule tells us three things.

●       Whether the offence is cognizable or non cognizable

●       Whether the offence is bailable or non bailable

●       Which court or Magistrate can try the offence

In simple words, whenever a student is confused about whether a particular offence under the BNS is cognizable or not, the First Schedule of the BNSS is the place to check, and not the punishment clause of the BNS itself. This is a common mistake many aspirants make while answering PYQ based questions.

As a general pattern, offences punishable with three years or more of imprisonment are usually cognizable and non bailable, while offences with lesser punishment are usually non cognizable and bailable. This is only a general trend and the exact position must always be checked from the Schedule, since there are exceptions.

Key Differences Between Cognizable and Non Cognizable Offences

●       Cognizable offences allow arrest without a warrant, while non cognizable offences require a warrant for arrest

●       Police can start investigation on their own in cognizable offences, but need a Magistrate's order under Section 174 of the BNSS in non cognizable offences

●       Cognizable offences are usually non bailable, while non cognizable offences are usually bailable

●       Cognizable offences are generally serious in nature, while non cognizable offences are generally minor or private in nature

●       In cognizable cases the police register a regular FIR under Section 173 of the BNSS, while in non cognizable cases the matter is entered in the NC Register

Procedure Once an Offence Is Classified

If the Offence Is Cognizable

The police must register the FIR, since the Lalita Kumari judgment discussed below makes registration mandatory once the information discloses a cognizable offence. After registration, investigation begins under Section 175 of the BNSS, and the accused may be arrested, produced before a Magistrate within twenty four hours, and the case may finally go for trial depending on the seriousness of the charge.

If the Offence Is Non Cognizable

The police simply note the complaint in the NC Register and inform the complainant that they must approach a Magistrate. If the Magistrate is satisfied, an order can be passed under Section 174 of the BNSS directing the police to investigate. Once such an order is passed, the police can proceed almost the same way as they would in a cognizable case.

If a person feels that the police are wrongly refusing to register an FIR even though the offence is cognizable, Section 173(4) of the BNSS allows the person to first approach the Superintendent of Police, and if that also fails, a complaint can be made before the Magistrate under Section 175 of the BNSS.

Zero FIR Meaning refers to an FIR that can be registered at any police station, regardless of where the offence occurred. Understanding Zero FIR Meaning is essential for Judiciary aspirants and anyone learning criminal procedure under BNSS. 

Case Law Section

Case Name: Lalita Kumari v. Government of Uttar Pradesh and Others

Citation: (2014) 2 SCC 1, decided by a Constitution Bench of the Supreme Court of India

Facts

The father of a minor girl approached the police to report that his daughter had been kidnapped. The police did not register an FIR immediately and instead carried out a preliminary inquiry, which delayed action on the complaint. The matter reached the Supreme Court through a writ petition, and because different Benches of the Court had earlier taken conflicting views on this point, the question was finally referred to a Constitution Bench.

Issue Before the Court

Whether a police officer is bound to register an FIR the moment information disclosing a cognizable offence is received, or whether the officer has the discretion to conduct a preliminary inquiry before deciding whether to register the FIR.

Court's Decision

The Constitution Bench held that registration of an FIR is mandatory if the information discloses the commission of a cognizable offence, and no preliminary inquiry is permitted in such a situation. The Court explained that the provision uses the word shall, which leaves no room for discretion once a cognizable offence is disclosed. At the same time, the Court carved out a narrow set of situations, such as matrimonial disputes, commercial offences, medical negligence cases and cases involving abnormal delay, where a limited preliminary inquiry may be conducted only to check whether a cognizable offence is made out at all, and such inquiry must be completed within seven days.

Important Observations

The Court observed that the credibility of the information is not a ground to refuse registration, since that evaluation belongs to the stage of investigation and not to the stage of registration. The Court also directed that reasons for not registering an FIR must be recorded in writing and reflected in the police diary, so that police discretion does not become police escape from duty.

Why the Case Is Important

As explained by Nitesh Choubey Sir during Judiciary Preparation sessions at Aashayein Judiciary, this judgment is the foundation of the entire law on FIR registration and continues to guide the working of Section 173 of the BNSS even after the change from the CrPC. Judiciary aspirants must remember this case whenever a question is framed on refusal to register an FIR in a cognizable offence.

Exam Relevance

Prelims POV

●       Definitions under Section 2(1)(g) and Section 2(1)(o) of the BNSS are frequently asked in objective papers

●       Role of the First Schedule of the BNSS in classifying offences as cognizable or non cognizable, bailable or non bailable

●       Sections 173, 174 and 175 of the BNSS dealing with FIR, non cognizable complaints and Magistrate's power

●       PYQ style fact based questions asking whether a given situation is cognizable or non cognizable

●       The ratio of Lalita Kumari v. Government of Uttar Pradesh on mandatory FIR registration

Mains POV

For Mains answer writing, begin with the statutory definitions under Section 2(1)(g) and Section 2(1)(o) of the BNSS, then explain the role of the First Schedule, and finally support the answer with the Lalita Kumari judgment while discussing the limited exceptions for preliminary inquiry. This structure shows both statutory knowledge and case law application, which examiners reward well.

Interview POV

Interview panels often ask a simple question such as, should the police be allowed to refuse an FIR if they think the complaint is false. A balanced answer explains that credibility of the complaint is not a ground for refusal at the registration stage, since that would give police an unchecked judicial function, but safeguards like preliminary inquiry in narrow categories and judicial review protect against misuse. This shows the candidate understands both police accountability and citizen rights.

Frequently Asked Questions

1. What is the main difference between a cognizable and a non cognizable offence?

A cognizable offence allows the police to arrest without a warrant and investigate on their own, while a non cognizable offence requires a warrant for arrest and a Magistrate's order before investigation can begin.

2. Where is the classification of cognizable and non cognizable offences found?

The classification is found in the First Schedule of the BNSS, 2023, and not in the Bharatiya Nyaya Sanhita itself.

3. Can the police refuse to register an FIR for a cognizable offence?

No. As held in Lalita Kumari v. Government of Uttar Pradesh, registration of an FIR is mandatory once the information discloses a cognizable offence, subject to a few narrow exceptions.

4. What can a person do if the police refuse to register an FIR?

The person can approach the Superintendent of Police under Section 173(4) of the BNSS, and if that fails, file a complaint before the Magistrate under Section 175 of the BNSS.

5. Are all cognizable offences non bailable?

Not always. Most cognizable offences are non bailable, but the exact position for every offence must be checked from the First Schedule of the BNSS, since some cognizable offences are bailable.

Conclusion

The distinction between cognizable and non cognizable offences decides how fast the police can act and how much judicial oversight is needed before that action. In simple words, the First Schedule of the BNSS is the map that every judiciary aspirant must know by heart, and the Lalita Kumari judgment is the compass that explains how the police must use their power to register an FIR.

Aashayein Judiciary continues to provide updated Judiciary Notes and Judiciary Study Material on such foundational topics to help aspirants build a strong base for the Civil Judge Exam and the PCS J Exam. According to the teaching approach followed at Aashayein Judiciary, mastering such basic classifications early makes it far easier to answer complex procedural questions later in both Judiciary Mains and Judiciary Interview rounds.
