Abstract
The distinction between cognizable and non-cognizable offences is one of the fundamental principles governing criminal procedure in India. It determines the extent of police authority in registering First Information Reports (FIRs), making arrests, conducting investigations, and maintaining public order while ensuring the protection of individual rights. With the enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), India’s criminal procedural framework has undergone significant reforms aimed at modernising police investigations through digital technology, forensic science, and victim-centric procedures. Although the BNSS replaces the Code of Criminal Procedure, 1973 (CrPC), it substantially retains the classification of offences while introducing procedural improvements. This article examines the legal framework governing cognizable and non-cognizable offences under both legislations, analyses the scope and limitations of police powers, discusses constitutional safeguards against arbitrary exercise of authority, and critically evaluates the reforms introduced by the BNSS. It further examines landmark judicial pronouncements that continue to guide the exercise of police powers in India.

Introduction
The criminal justice system seeks to balance effective law enforcement with the protection of individual rights. In India, the police play a vital role in preventing crime, investigating offences, and maintaining public order, but their powers are regulated by procedural law to prevent arbitrary action.
A key feature of Indian criminal procedure is the distinction between cognizable and non-cognizable offences, which determines the police’s authority to register an FIR, investigate offences, and make arrests. While the Code of Criminal Procedure, 1973 (CrPC) governed these powers for decades, it has now been replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which retains this classification while introducing reforms such as e-FIRs, digital investigations, and greater use of forensic science. The distinction between these categories of offences has profound constitutional implications. Police powers directly affect the fundamental rights guaranteed under Articles 20, 21 and 22 of the Constitution of India, particularly the right to life and personal liberty, protection against arbitrary arrest, and procedural fairness. Accordingly, the Supreme Court of India has repeatedly emphasised that police powers must always be exercised reasonably, proportionately, and in accordance with the procedure established by law.
This article seeks to examine the concepts of cognizable and non-cognizable offences through a comparative analysis of the Code of Criminal Procedure, 1973 and the Bharatiya Nagarik Suraksha Sanhita, 2023. It further analyses the scope of police powers, important judicial pronouncements, constitutional safeguards, and the practical challenges associated with the implementation of the new procedural framework.
Meaning and Classification of Offences
In criminal jurisprudence, an offence refers to any act or omission made punishable by law. Every offence is regarded as a wrong against society because it disturbs public order and affects the collective interest of the community. The State, therefore, assumes the responsibility of prosecuting offenders to ensure justice and maintain social order. The criminal justice system classifies offences into different categories depending upon their seriousness, punishment, and procedural requirements. Among these classifications, the distinction between cognizable and non-cognizable offences occupies a central position because it determines the extent of police authority during the investigation process.
A cognizable offence authorises the police to register an FIR, investigate the matter without prior permission of the Magistrate, and arrest the accused without a warrant where permitted by law. Such offences generally involve serious crimes affecting life, liberty, public safety, or national security. On the other hand, a non-cognizable offence is comparatively less serious in nature. In such cases, the police cannot investigate the offence or arrest the accused without obtaining prior permission from the competent Magistrate. This procedural safeguard ensures judicial supervision before coercive police powers are exercised.
The legislative philosophy behind this distinction is to strike a balance between effective law enforcement and protection of individual liberty. Serious offences require immediate intervention by the police to preserve evidence, prevent further harm, and secure the accused, whereas comparatively minor offences are subjected to judicial scrutiny before investigation begins. Although the BNSS, 2023 has replaced the CrPC, 1973, it retains this fundamental classification. However, the new legislation seeks to improve procedural efficiency by incorporating technological advancements and strengthening investigative mechanisms without compromising constitutional safeguards.
Cognizable Offences: Nature, Scope and Police Powers
The classification of an offence as cognizable has significant procedural consequences because it determines the extent to which the police may act independently during criminal proceedings. A cognizable offence is generally one involving serious harm to individuals or society, where any delay in police intervention may lead to destruction of evidence, absconding of the accused, or further commission of offences. Consequently, the law empowers the police to take immediate action without waiting for prior judicial approval.
Under Section 2(c) of the Code of Criminal Procedure, 1973 (CrPC), a cognizable offence means an offence for which a police officer may arrest without a warrant in accordance with the First Schedule or any other law in force. The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) substantially retains this definition under Section 2(1)(g), thereby preserving the legislative distinction that has existed under Indian criminal procedure for decades.
The police derive three important powers in relation to cognizable offences:
a) to register a First Information Report (FIR);
b) to investigate the offence without prior permission of the Magistrate; and
c) to arrest the accused without a warrant wherever the statutory conditions are fulfilled.
Non-Cognizable Offences: Scope and Procedure
Unlike cognizable offences, non-cognizable offences involve comparatively less serious conduct and are therefore subject to greater judicial supervision. The police cannot exercise unrestricted investigative powers in such cases because the legislature considers judicial oversight necessary before coercive measures are adopted. Under Section 2(l) of the CrPC and Section 2(1)(o) of the BNSS, a non-cognizable offence is one in which a police officer has no authority to arrest without a warrant. The procedural framework governing these offences is provided under Section 155 of the CrPC and Section 174 of the BNSS.
When information relating to a non-cognizable offence is received, the police ordinarily record it in the prescribed register and advise the informant to approach the competent Magistrate. Investigation can commence only after the Magistrate grants permission. This procedural requirement reflects the constitutional principle that restrictions upon personal liberty must be subject to judicial scrutiny, particularly where the offence is not of such gravity as to justify immediate police intervention.
Examples of non-cognizable offences include:
Defamation; Public nuisance; Simple assault in appropriate circumstances; Criminal intimidation attracting comparatively lesser punishment; and Minor acts of mischief.
Police Powers Explained under the CrPC, 1973 and the BNSS, 2023
The police serve as the primary agency responsible for enforcing criminal law and maintaining public order. Their powers are not merely administrative but are statutory in nature, deriving authority from the Code of Criminal Procedure, 1973 (CrPC), and now the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS). These powers enable the police to prevent crime, investigate offences, apprehend offenders, and assist in the administration of justice. At the same time, such powers are subject to constitutional limitations to prevent arbitrariness and misuse.
The BNSS substantially retains the framework of police powers under the CrPC while introducing procedural reforms aimed at improving efficiency, transparency, and the use of technology. The following discussion explains the major police powers and their evolution under the new legislation.
1. Power to Register the First Information Report (FIR)
The First Information Report (FIR) is the foundation of a criminal investigation. It records the earliest information regarding the commission of a cognizable offence and enables the police to commence investigation without unnecessary delay.
Under Section 154 of the CrPC, every information relating to the commission of a cognizable offence must be reduced to writing, read over to the informant, signed by the informant, and entered into the prescribed register. The corresponding provision under the BNSS is Section 173, which substantially retains this procedure while introducing the concept of electronic communication and e-FIRs. This reform reflects the legislature’s intention to make criminal justice more accessible and technology-oriented.
The significance of mandatory FIR registration was authoritatively settled in Lalita Kumari v. Government of Uttar Pradesh, where the Supreme Court held that registration of an FIR is mandatory if the information discloses the commission of a cognizable offence. The Court clarified that a preliminary inquiry is permissible only in exceptional categories of cases and cannot become a routine practice. This judgment has greatly strengthened transparency and accountability in police functioning.
2. Power of Arrest
The power to arrest is one of the most significant coercive powers available to the police. It directly affects an individual’s personal liberty and therefore must be exercised with caution, fairness, and in accordance with statutory requirements. Under Section 41 of the CrPC, a police officer may arrest a person without a warrant in specified circumstances involving cognizable offences. The corresponding provision under the BNSS is Section 35, which substantially retains the earlier framework but introduces an important safeguard by requiring prior approval of a Deputy Superintendent of Police before arresting certain elderly or infirm persons accused of offences punishable with imprisonment of less than three years, unless exceptional circumstances justify immediate arrest.
The Supreme Court has repeatedly emphasised that the power to arrest should not be exercised mechanically. In Joginder Kumar v. State of Uttar Pradesh, the Court held that an arrest cannot be justified merely because it is lawful; it must also be necessary and reasonable in the circumstances of the case.
Similarly, in Arnesh Kumar v. State of Bihar, the Supreme Court directed police officers to strictly comply with statutory safeguards before making arrests in offences punishable with imprisonment up to seven years. The Court observed that unnecessary arrests not only violate individual liberty but also contribute to overcrowding in prisons. These judgments continue to guide police authorities even under the BNSS and reinforce the constitutional protection of personal liberty under Article 21 of the Constitution.
3. Power to Investigate
Under Section 156 of the CrPC, the police may investigate cognizable offences without obtaining prior permission from a Magistrate. The corresponding provision under the BNSS is Section 175, which preserves this authority while encouraging greater use of forensic science, electronic evidence, and digital documentation.²¹
One of the notable features of the BNSS is its emphasis on scientific investigation. The legislation seeks to reduce dependence on oral testimony by encouraging forensic examination, digital evidence, and technological support in criminal investigations. Such reforms are expected to improve the accuracy and credibility of criminal investigations.
However, investigations relating to non-cognizable offences continue to require prior permission from the Magistrate under Section 155 of the CrPC and Section 174 of the BNSS, thereby preserving judicial oversight in less serious matters.
4. Power of Search and Seizure
Search and seizure are essential investigative tools through which the police recover documents, weapons, electronic devices, or other material evidence connected with an offence. The CrPC empowers the police to conduct searches and seize relevant property in accordance with prescribed procedures. The BNSS substantially retains these powers but encourages greater use of electronic documentation, digital inventories, audio-video recording of search proceedings, and scientific preservation of evidence. These procedural improvements are intended to increase transparency, minimise allegations of fabricated recoveries, and strengthen the evidentiary value of seized materials before the courts.
5. Submission of Police Report
Upon completion of the investigation, the investigating officer submits a police report before the Magistrate. Under Section 173 of the CrPC, the investigating officer may file either a charge-sheet where sufficient evidence exists or a closure report where evidence is inadequate. The corresponding provision under the BNSS is Section 193, which substantially preserves this framework while facilitating electronic submission of investigation records and digital case management. Timely submission of the police report is essential for ensuring expeditious criminal trials and preventing unnecessary delay in the administration of justice.
6. Constitutional Safeguards Governing Police Powers
While police powers are indispensable for maintaining law and order, they are not unlimited. Every exercise of police authority must conform to the constitutional guarantees contained in Articles 20, 21, and 22 of the Constitution of India. Article 21 guarantees that no person shall be deprived of life or personal liberty except according to the procedure established by law. Article 22 protects individuals against arbitrary arrest by requiring that every arrested person be informed of the grounds of arrest, be allowed to consult a legal practitioner of their choice, and be produced before a Magistrate within twenty-four hours. These safeguards ensure that criminal investigations remain consistent with the principles of fairness, due process, and the rule of law.
The Supreme Court further strengthened these protections in D.K. Basu v. State of West Bengal by prescribing detailed guidelines relating to arrests, detention, medical examination, and communication with family members. These safeguards continue to govern police conduct under the BNS.
Critical Analysis: Police Powers under the CrPC and BNSS
The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) modernises criminal procedure by retaining the core framework of the Code of Criminal Procedure, 1973 while introducing digital investigations, electronic FIRs, audio-video recording, and greater reliance on forensic science. These reforms aim to improve transparency, efficiency, and accessibility in criminal investigations. However, their success depends on effective implementation. Many police stations continue to face inadequate digital infrastructure, shortage of trained personnel, and limited forensic facilities, particularly in rural areas. Although the BNSS strengthens procedural safeguards against arbitrary police action, judicial decisions such as Joginder Kumar, Arnesh Kumar, and D.K. Basu remain crucial in protecting personal liberty and ensuring accountability. The increased use of technology also raises concerns regarding data privacy and the handling of electronic evidence.
Overall, the BNSS represents a progressive step towards modernising criminal procedure. Nevertheless, its long-term success will depend upon effective implementation, continuous judicial oversight, police training, technological preparedness, and unwavering commitment to constitutional values.
Challenges in the Exercise of Police Powers
Despite statutory safeguards, several practical challenges continue to affect the exercise of police powers in India.
7.1 Arbitrary Arrests
Although arrest is intended to facilitate investigation and secure the presence of the accused, it is sometimes exercised mechanically without sufficient justification. Such practices not only violate personal liberty but also contribute to unnecessary detention and overcrowding in prisons. Judicial guidelines laid down in Joginder Kumar and Arnesh Kumar seek to prevent such misuse, yet effective implementation remains inconsistent.²⁸
7.2 Delay in Registration of FIRs
The refusal or delay in registering FIRs continues to undermine public confidence in the criminal justice system. Although Lalita Kumari makes FIR registration mandatory in cognizable offences, victims occasionally encounter reluctance on the part of law enforcement agencies. The introduction of electronic FIRs under Section 173 of the BNSS may help address this issue, provided sufficient technological infrastructure exists.²⁹
7.3 Inadequate Investigative Resources
Efficient criminal investigation requires trained investigators, modern forensic laboratories, cyber experts, and advanced technological equipment. Many investigating agencies continue to face shortages of personnel and resources, leading to delays in investigation and prosecution.
7.4 Human Rights Concerns
Allegations relating to custodial violence, illegal detention, coercive interrogation, and violation of procedural safeguards continue to pose serious challenges. Such practices undermine public confidence in law enforcement and contradict the constitutional commitment to dignity, equality, and personal liberty.
7.5 Implementation Challenges under the BNSS
The successful implementation of the BNSS requires:
• Extensive police training;
• Upgraded digital infrastructure;
• Improved forensic capacity;
• Awareness among legal practitioners; and
• Effective coordination between police, prosecution, and judiciary.
Without these institutional reforms, many of the procedural innovations introduced by the BNSS may fail to achieve their intended objectives.
Suggestions and Recommendations
To strengthen the criminal justice system and ensure responsible exercise of police powers, the following measures deserve consideration:
1.Comprehensive Training: Regular training programmes should familiarise police officers with the provisions of the BNSS, constitutional safeguards, cyber investigations, and forensic techniques.
2.Strengthening Digital Infrastructure: Adequate technological facilities should be established to effectively implement electronic FIRs, digital investigations, and electronic case management systems.
3.Expansion of Forensic Facilities: Greater investment in forensic laboratories and scientific investigation will improve the quality of evidence and reduce dependence on unreliable oral testimony.
4.Strict Compliance with Judicial Guidelines: Police authorities must ensure strict adherence to the principles laid down in Lalita Kumari, Joginder Kumar, Arnesh Kumar, and D.K. Basu.
5.Public Legal Awareness: Citizens should be educated regarding their rights during arrest, investigation, and criminal proceedings to promote greater accountability.
6.Independent Oversight Mechanisms: Complaints relating to custodial violence, abuse of authority, and procedural irregularities should be investigated through independent and impartial mechanisms.
These measures would contribute towards a criminal justice system that is efficient, transparent, and fully consistent with constitutional principles.
Conclusion
The distinction between cognizable and non-cognizable offences forms the foundation of police powers under India’s criminal justice system. While the Bharatiya Nagarik Suraksha Sanhita, 2023 preserves this classification, it modernises criminal procedure through technological advancements, electronic FIRs, and greater reliance on forensic science. These reforms have the potential to enhance efficiency, transparency, and access to justice. However, their effectiveness depends upon proper implementation, adequate infrastructure, continuous police training, and judicial oversight. Ultimately, the responsible exercise of police powers must uphold constitutional guarantees of fairness, liberty, and due process, ensuring that the objectives of justice are achieved without compromising individual rights.
