The Arrest That Can Happen Without a Magistrate's Word
The Statutory Definitions: Section 2(c) and Section 2(l) CrPC
Judicial Interpretation: How Courts Have Shaped These Powers
A murder suspect is arrested at midnight without the police approaching any Magistrate. A neighbour who causes a minor nuisance cannot be hauled in by the police on their own authority. Both situations flow from a single definitional divide in the Code of Criminal Procedure, 1973 — whether the offence in question is cognizable or non-cognizable.
That divide, established at the threshold by Section 2(c) CrPC, and operationalised through Schedule I of the Code, is arguably the most consequential classification in Indian criminal procedure. It governs not merely the mechanics of arrest but the entire arc of police power from the moment an offence is reported to the filing of the charge-sheet.
The Statutory Definitions: Section 2(c) and Section 2(l) CrPC
Section 2(c) — Cognizable Offence and Cognizable Case
Section 2(c) of the Code of Criminal Procedure, 1973 provides that a "cognizable offence" means an offence for which, and a "cognizable case" means a case in which, a police officer may, in accordance with the First Schedule or under any other law for the time being in force, arrest without warrant.
The definition is deceptively simple. Its operative content lies not in the section itself but in the reference it makes — to Schedule I and to any other law that confers the power of warrantless arrest.
The phrase "in accordance with the First Schedule or under any other law for the time being in force" creates two separate tracks through which an offence acquires the character of cognizability.
The Code classifies offences against the Indian Penal Code (now the Bharatiya Nyaya Sanhita, 2023) directly through Schedule I. For offences under special and local laws, the residual provision of Schedule I applies unless the special statute itself speaks to the question.
Section 2(l) — Non-Cognizable Offence and Non-Cognizable Case
By contrast, a "non-cognizable offence" under Section 2(l) CrPC is an offence for which, and a "non-cognizable case" is a case in which, a police officer has no authority to arrest without warrant.
The definition operates purely as a negative — an offence is non-cognizable simply because it falls outside the scope of Section 2(c). There is no distinct set of characteristics that stamp an offence as non-cognizable; the absence of the power to arrest without warrant is itself the defining trait.
Case and Offence: Not the Same Thing
One distinction that the courts have consistently drawn is between a case and an offence. The two terms are not synonymous, though an offence always leads to a case. As judicially clarified in Vijayaraghavan v. C.B.I. (1984 CrLJ 1277), a case may involve the commission of more than one offence, and the classification of the case as cognizable or non-cognizable turns on the nature of those offences taken together.
When a police officer receives information about the commission of a cognizable offence and records the same, he is said to register a case — and the power of the police under Chapter XII of the Code flows from that registration.
Schedule I: The Mechanism That Classifies Every Offence
Column 3 and What It Actually Does
Schedule I of the Code of Criminal Procedure, 1973, is the operational heart of the cognizability framework. It is divided into two parts — Part I, which classifies offences under the Indian Penal Code, and Part II, which deals with offences under other laws. The Schedule presents a table of offences, and it is Column 3 of that table that determines whether the police may arrest without warrant.
Broadly speaking, Column 3 designates as cognizable those offences which call for a speedy investigation — offences such as murder, kidnapping, robbery, and dacoity. The rationale is practical: these are offences where delay in action may mean escape of the accused, destruction of evidence, or further harm to the public.
For the more minor offences, where the need for immediate police action is not as pressing, the column designates the offence non-cognizable, requiring the police to obtain a Magistrate's warrant before effecting an arrest.
Offences Under Special and Local Laws
The last item of Schedule I addresses offences against laws other than the IPC. Here, the classification follows a general rule tied to the gravity of punishment. Offences under other laws that are punishable with imprisonment for three years and upwards are ordinarily treated as cognizable.
Those carrying lesser punishment are non-cognizable. The Delhi Public Gambling Act, 1955 (Sections 3-4) and the Essential Commodities Act, 1955 (by virtue of Section 10A, inserted by Act 36 of 1967) are illustrations of statutes whose offences acquire cognizability through this route.
Where a special law creates an offence but does not specify whether it is cognizable or non-cognizable, the matter is determined with reference to Part II of Schedule I, as settled in Avinash v. State of Maharashtra (1983 CrLJ 1833).
If, however, the special Act designates a particular officer to make arrests, only that officer — and no other — is competent to arrest without a warrant, as was laid down in Delhi Administration v. Prakash (AIR 1967 Del 15).
Section 41 CrPC: When the Police May Arrest Without Warrant
The 2009 Amendment and Conditions for Arrest
Section 41 of the Code of Criminal Procedure, 1973 is the centrepiece provision governing police arrests. It permits any police officer to arrest, without an order from a Magistrate and without a warrant, a person who commits a cognizable offence in the presence of the police officer, or against whom a reasonable complaint has been made, or credible information has been received, or a reasonable suspicion exists, that he has committed a cognizable offence.
The section as it stood post the 2009 amendment introduced a significant check on arbitrary arrests. Where the cognizable offence in question is punishable with imprisonment for a term which may be less than seven years, or which may extend to seven years (whether with or without fine), an arrest is not automatic.
The police officer must additionally be satisfied that the arrest is necessary for one of the specified purposes — to prevent further offence, for proper investigation, to prevent tampering with evidence, to prevent inducement or threat to witnesses, or to ensure the accused's presence before Court. The police officer is required to record the reasons for making — and equally, for not making — the arrest in writing.
It bears emphasis that the existence of the power to arrest is one thing; the justification for its exercise is quite another. The power of arrest is neither absolute nor to be exercised mechanically, as the Rajasthan High Court (Division Bench) reiterated in State of Rajasthan v. Bhera (1997 CrLJ, Raj DB).
No person can be arrested on a mere suspicion under Section 41 unless the suspicion is well-founded and supported by definite facts, as distinguished from vague surmise, as the courts have consistently held since Charuchandra in re. (1916) 44 Cal 86 (FB).
Section 42: Arrest for Non-Cognizable Offences on Refusal to Give Name
Where the offence committed is non-cognizable, the general rule is categorical: a police officer has no power to arrest without a warrant. The only exception carved out by the Code is under Section 42, which permits arrest where a person who commits a non-cognizable offence in the presence of the police officer refuses to give his name and address, or gives a name and residence which the officer has reason to believe is false.
Even in this exceptional case, the arrest is purely to ascertain the person's identity and the accused must be released as soon as the name and address are ascertained upon execution of a bond for appearance.
If even after the arrest the name and address cannot be ascertained, the person cannot be kept in police custody beyond 24 hours and must be produced before a Magistrate — as is clear from Gopal v. Emperor (1922) 46 Mad 605.
The rules of English common law, it was held in the same case, cannot be invoked outside Section 42 to justify a warrantless arrest in a non-cognizable case.
Investigation: The Sharper Practical Difference
Section 155(2): The Magistrate's Gate
If the arrest power is one practical consequence of the cognizable/non-cognizable divide, the power to investigate is perhaps a sharper one. Section 155(2) CrPC provides that no police officer shall investigate a non-cognizable case without the order of a Magistrate having jurisdiction over such case.
This is not merely a procedural formality. If the police officer does investigate a non-cognizable case without such an order, his investigation report does not become a police report for the purposes of Section 173; it is treated instead as a complaint under Section 2(d), as clarified by the Explanation to Section 2(d) of the Code.
The High Court, in such a situation, may quash proceedings and remand the case to the Magistrate to proceed afresh. However, where the trial is concluded, it cannot be set aside on this ground alone unless a failure of justice has been occasioned — the principle traceable to H.N. Rishbud v. State (AIR 1955 SC 196).
Section 155(4): Mixed Offences and the Legal Fiction
In practice, a single transaction often discloses both cognizable and non-cognizable offences. Section 155(4) CrPC addresses this directly through a legal fiction: where information discloses both types of offences, the police officer may treat the entire case as a cognizable case and investigate it without any Magistrate's order, sending up a single police report under Section 173 that may comprise non-cognizable offences as well.
This provision codified the Supreme Court's ruling in Pravin Chandra Mody v. State of A.P. (AIR 1965 SC 1185). The effect was elaborated further: since sub-section (4) creates a legal fiction that makes non-cognizable offences cognizable where they accompany cognizable offences, the police have no option but to investigate the whole case and submit a charge-sheet in respect of all the offences, provided they are prima facie made out.
To illustrate, the offence under Section 494 IPC (bigamy) is ordinarily non-cognizable; but where it was investigated along with Section 498A IPC and Section 4 of the Dowry Prohibition Act (both cognizable), the Investigating Officer was fully authorised under Section 155(4) to investigate the Section 494 offence as part of the same case.
Judicial Interpretation: How Courts Have Shaped These Powers
Pravin Chandra Mody v. State of A.P. (AIR 1965 SC 1185)
Pravin Chandra Mody remains the foundational authority on the scope of police power where a transaction discloses mixed offences. The Supreme Court held that the police officer need not bifurcate his investigation, approaching a Magistrate for permission to investigate the non-cognizable component while proceeding independently on the cognizable one. The subsequent codification in Section 155(4) is, in effect, a parliamentary endorsement of this ruling.
Avinash v. State of Maharashtra (1983 CrLJ 1833)
This decision is authority for two important propositions. First, where a special law does not specify whether an offence is cognizable or non-cognizable, Part II of Schedule I provides the applicable classification.
Second — and this is the critical qualification — Section 41(1) confers a general power to arrest without warrant but that power does not automatically authorise the police officer to investigate the case if the offence is non-cognizable; investigation without a Magistrate's order under Section 155(2) remains impermissible.
Joginder Kumar v. State of U.P. (AIR 1994 SC)
Joginder Kumar stands for the proposition that arrest is not compelled merely because it is lawful. The Supreme Court categorically stated that except in heinous offences, an arrest must be avoided if the police officer can instead issue a notice requiring the person to attend the police station.
The discretion to arrest, though exercised without a Magistrate's warrant in cognizable cases, is not absolute and must be guided by the principle that personal liberty — guaranteed under Article 21 of the Constitution of India — is not to be curtailed lightly.
D.K. Basu v. State of West Bengal and the Safeguards Regime
The guidelines issued by the Supreme Court in D.K. Basu v. State of West Bengal operate as a constitutional overlay on the statutory powers under Section 41.
The Court directed, inter alia, that the arrestee be informed of the grounds of arrest, that the inspecting memo recording injuries on the arrestee's person be signed by both parties and a copy provided to the arrestee, and that the arrestee be subjected to medical examination by a trained doctor every 48 hours during detention.
These requirements, the Supreme Court held in A.N. Bhatti v. State of Gujarat (AIR 2005 SC 2115), are in addition to the constitutional and statutory safeguards under the Code — they do not detract from them.
BNSS 2023: What Has Changed and What Has Not
Section 2(1)(g) BNSS: Definition Carries Over Unchanged
The Bharatiya Nagrik Suraksha Sanhita, 2023 (BNSS), which has replaced the Code of Criminal Procedure, 1973, carries the definition of cognizable offence over into Section 2(1)(g) BNSS without any substantive alteration.
The comparison table compiled by Anil Kishore Yadav, IPS, Director, CAPT Bhopal, confirms that the change is "No change." Similarly, the definition of non-cognizable offence (now Section 2(1)(o) BNSS, corresponding to Section 2(l) CrPC) is carried forward unchanged. The entire definitional architecture of Section 2(c) CrPC thus survives into the new regime intact.
Section 35 BNSS: The Critical New Restriction on Arrest
The most significant departure in the BNSS from the CrPC in the context of arrest powers is found in Section 35 BNSS (corresponding to Sections 41 and 41A CrPC). A new sub-section (7) has been introduced which states: "No arrest shall be made without prior permission of an officer not below the rank of Deputy Superintendent of Police in case of an offence which is punishable for imprisonment of less than three years and such person is infirm or is above sixty years of age."
This is a material substantive change. Under the CrPC, age and infirmity were factors that the police officer could consider in the exercise of discretion; they were not a hard bar requiring prior sanction.
Under the BNSS, where the offence carries a sentence of less than three years and the accused is either infirm or above sixty years of age, no arrest can be made without the prior sanction of a DSP-level officer. This provision significantly reinforces the personal liberty calculus in cases of minor cognizable offences involving vulnerable persons.
Section 173 BNSS: Zero FIR and the eFIR — Expanding Reach of Cognizable Machinery
Section 173 BNSS (corresponding to Section 154 CrPC, which deals with information in cognizable cases — the FIR provision) introduces two important innovations.
First, by adding the words "irrespective of the area where the offence is committed," the BNSS formally entrenches the concept of the Zero FIR — enabling any police station to record the FIR for a cognizable offence regardless of territorial jurisdiction, with subsequent transfer to the appropriate station.
Second, the addition of the words "by electronic communication" and the introduction of clause (ii) to sub-section (1) effectively recognises the eFIR, allowing information about a cognizable offence to be submitted electronically.
A new sub-section (3) also introduces a preliminary inquiry requirement for cognizable offences punishable with three years or more but less than seven years before proceeding to full investigation.
Section 174 BNSS: Non-Cognizable Cases Now Reportable Fortnightly
Section 174 BNSS (corresponding to Section 155 CrPC) adds a new clause (ii) to sub-section (1) requiring the forwarding of the daily diary report of non-cognizable cases fortnightly to the Magistrate.
This addresses a well-recognised lacuna: under the CrPC, the only check on non-cognizable cases was the requirement of a Magistrate's order before investigation. The fortnightly reporting obligation introduces a supervisory mechanism that ensures the Magistrate is kept continuously informed of such cases even before any investigation commences.
Common Misconceptions
Misconception 1: All cognizable offences require arrest. This is incorrect. The power to arrest without warrant exists in cognizable cases, but the exercise of that power is conditioned — post the 2009 amendment and reinforced by judicial doctrine — on the police officer's genuine satisfaction that arrest is necessary for specified purposes. Arrest merely because it is lawful to do so has been firmly disapproved by the Supreme Court.
Misconception 2: A non-cognizable offence cannot ever lead to arrest. This is an overstatement. A person who commits a non-cognizable offence and refuses to give his name and address — or gives a false one — can be arrested under Section 42 CrPC (Section 39 BNSS). The arrest is narrowly purposive: to ascertain identity. It does not convert the offence into a cognizable one, and the power to investigate without a Magistrate's order does not arise.
Misconception 3: Once the Magistrate orders investigation of a non-cognizable case, all powers of arrest follow. The exception regarding arrest is deliberately narrow. A Magistrate's order to investigate a non-cognizable case under Section 155(2) does not confer upon the police officer the power to arrest without warrant as available in a cognizable case. The investigative power expands, but the arrest power remains governed by Section 41(1) as it ordinarily applies — as settled in Chari v. State of U.P. (1951 SCR 312 (315), AIR 1951 SC 207).
Conclusion
The cognizable/non-cognizable divide in Indian criminal procedure is not a mere taxonomical exercise. It is the constitutional and statutory fulcrum on which the balance between effective law enforcement and individual liberty rests.
Section 2(c) CrPC — now Section 2(1)(g) BNSS — draws the line, and Schedule I operationalises it with reference to every offence in the statute book. The police power to arrest without warrant, the power to investigate without a Magistrate's order, and the entire machinery of the First Information Report are all downstream consequences of this classification.
The BNSS has, on balance, carried the structure forward unchanged while introducing targeted reforms — the DSP-level sanction for arrest of elderly or infirm persons in minor cognizable cases, the Zero FIR and eFIR for cognizable offences, and the fortnightly Magistrate reporting for non-cognizable cases.
These are refinements at the margins; the foundational architecture remains as the CrPC built it. For the practising advocate and the law student alike, the starting point remains the same: identify the offence, locate it in Schedule I, and the entire procedural map follows from that single act of classification.
Frequently Asked Questions
Q: What is the difference between a cognizable and a non-cognizable offence under CrPC?
A cognizable offence under Section 2(c) CrPC is one for which a police officer may arrest without a warrant in accordance with Schedule I or under any other law. A non-cognizable offence under Section 2(l) is one where no such power of warrantless arrest exists. The distinction further governs whether the police can investigate the case without a Magistrate's order — they cannot in non-cognizable cases.
Q: How does Schedule I of the CrPC determine whether an offence is cognizable?
Schedule I is divided into two parts. Part I classifies offences under the IPC, and Column 3 of the Schedule specifies whether the offence is cognizable or non-cognizable. Part II covers offences under other laws and generally treats offences punishable with three or more years' imprisonment as cognizable. Where a special law is silent on the question, Part II of Schedule I provides the applicable classification.
Q: Can the police investigate a non-cognizable offence on their own?
No. Under Section 155(2) CrPC (Section 174 BNSS), a police officer cannot investigate a non-cognizable case without the order of a Magistrate having jurisdiction. If the police investigate without such an order, their report is treated as a complaint rather than a police report for purposes of taking cognizance.
Q: What happens when the same incident involves both cognizable and non-cognizable offences?
Section 155(4) CrPC creates a legal fiction: where information discloses both cognizable and non-cognizable offences, the police may treat the entire case as cognizable, investigate the whole matter without a Magistrate's order, and file a single police report under Section 173. This position was settled by the Supreme Court in Pravin Chandra Mody v. State of A.P. (AIR 1965 SC 1185) and codified in the provision.
Q: What changes has the BNSS 2023 made to arrest powers in cognizable offences?
The definition of cognizable offence in Section 2(1)(g) BNSS is identical to Section 2(c) CrPC. The most significant change is in Section 35 BNSS (corresponding to Section 41 CrPC), which adds a new sub-section (7): no arrest can be made without prior permission of an officer not below the rank of DSP where the offence carries imprisonment of less than three years and the accused is either infirm or above sixty years of age. Additionally, Section 173 BNSS introduces Zero FIR and eFIR for cognizable offences, broadening the reach of the cognizable case machinery.
