The First Responders of Justice: Understanding the Role of Police in Criminal Investigation Under BNSS 2023
Think of the police as the engine that powers the entire criminal justice machine. Without a proper investigation at the first stage, even the most well-drafted charge sheet and the most skilled courtroom advocacy cannot deliver justice to a victim. The police are not merely enforcers of law; they are the primary interface between the state and the citizen, between a crime committed and a conviction secured.
The criminal investigation system in India has undergone a historic transformation with the enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023. These landmark legislations have modernised the procedural framework, integrating technology and transparency into the investigation process while simultaneously reinforcing constitutional safeguards for the accused and victims alike. This article examines the role of police in criminal investigation in India in its entirety, covering its legal definition, governing statutory provisions, duties, limitations, landmark judgments, and practical applications in the modern era.
What Is Criminal Investigation? The Legal Definition and Its Scope Under BNSS 2023
Criminal investigation refers to the process by which police authorities collect evidence pertaining to the commission of an offence. It commences with the registration of a First Information Report and continues until the submission of the final police report before the Magistrate. Under the Bharatiya Nagarik Suraksha Sanhita, 2023, investigation encompasses all proceedings conducted by police officers for the purpose of collecting evidence, determining facts, and identifying the persons responsible for the commission of an offence.
The fundamental objective of criminal investigation is to ascertain the truth through lawful means. An investigation must be conducted in a fair, impartial, and objective manner, consistent with the constitutional safeguards guaranteed to every citizen. It is not an exercise in confirming a preconceived narrative; it is a structured, evidence-driven inquiry that must respect the rights of both the victim and the accused at every stage.
The Legal Architecture: Laws and Key Sections Governing Police Investigation in India
The investigative powers of the police in India are governed by a comprehensive legislative framework. The Bharatiya Nyaya Sanhita, 2023 defines substantive offences and their punishment. The Bharatiya Nagarik Suraksha Sanhita, 2023 lays down the procedural steps for investigation, arrest, and trial. The Bharatiya Sakshya Adhiniyam, 2023 determines the admissibility and validity of evidence gathered during investigation. Overarching all of these is the Constitution of India, which sets the non-negotiable boundaries within which all investigative action must remain.
The key sections under the BNSS that directly govern police investigation are as follows.
Section 173 deals with the registration of First Information Reports, including the introduction of e-FIR for electronic filing of complaints. The police cannot refuse to register an FIR where the information discloses the commission of a cognizable offence.
Section 175 confers upon police officers the authority to investigate cognizable offences without prior permission of the Magistrate, enabling immediate investigative action upon receipt of a complaint.
Section 180 governs the power of police to examine witnesses and record their statements during the course of investigation.
Section 35 provides the conditions under which an arrest without a warrant may be made, along with the procedural safeguards that must be observed.
Sections 105 and 185 regulate the power of search and seizure, requiring the police to follow established protocols to ensure that seized evidence retains its legal validity.
Section 193 requires the investigating officer to submit a final police report before the Magistrate upon completion of the investigation.
Under the Bharatiya Sakshya Adhiniyam, 2023, three provisions are of particular relevance to police investigations. Section 22 renders confessions obtained through inducement, threat, coercion, or promise inadmissible in criminal proceedings. Section 23 provides that confessions made directly to police officers are generally inadmissible as evidence. Sections 61 to 63 establish the framework for the admissibility of electronic and digital records, recognising them as valid evidence carrying the same weight as paper documents and laying down conditions for the admissibility of computer-generated evidence.
Investigation in Action: A Step-by-Step Real-World Scenario Explained
To understand how criminal investigation operates in practice, consider a concrete scenario. A jeweller reports to the police that his shop was broken into during a public holiday and that cash along with jewellery has been stolen. On receipt of the complaint, the police register an FIR under the relevant provisions of the Bharatiya Nagarik Suraksha Sanhita, 2023.
The investigating officer visits the shop to examine the crime scene. Photographs are taken, fingerprints are lifted, and CCTV footage from nearby establishments is collected and preserved. Statements are recorded from neighbours and employees who may have observed suspicious activity. If a suspect is identified, the police may proceed to arrest, strictly following the procedural safeguards prescribed under law.
If electronic evidence is available, it is collected and preserved in accordance with the Bharatiya Sakshya Adhiniyam, 2023 to ensure its admissibility before the court. Every step of this process, from FIR registration to the final report, is governed by law and must be executed with precision. A procedural error at any stage can compromise the entire prosecution.
The Six Core Duties of Police in Criminal Investigation Every Citizen Should Know
1. The Duty to Preserve Evidence: The Chain of Custody Cannot Be Broken
It is the primary duty of the investigating officer to ensure that all evidence collected at the scene of crime is properly sealed, labelled, and documented. Maintaining an unbroken chain of custody is essential to the admissibility of evidence before the court. Any gap or irregularity in the preservation of evidence can allow the defence to challenge its authenticity.
2. The Duty to Safeguard the Rights of the Accused: Arrest Is Not Punishment
The police are duty-bound to inform every arrested person of the grounds of their arrest, provide them access to legal counsel without delay, and produce them before a Magistrate within twenty-four hours of arrest. These are not procedural formalities; they are constitutional obligations that directly reflect the right to personal liberty guaranteed under Article 21.
3. The Duty to Maintain a Case Diary: Transparency at Every Step
During the course of investigation, the investigating officer must maintain a case diary recording each procedural step taken. This document serves as a contemporaneous record of the investigation, ensures transparency and accountability, and is available to the court for scrutiny during trial.
4. The Duty to Register the FIR: No Complaint Can Be Turned Away
The police are legally obligated to register a First Information Report wherever a complaint discloses the commission of a cognizable offence. Refusal to register an FIR is not merely a procedural lapse; it is an abdication of statutory responsibility that directly denies the victim access to justice.
5. The Duty of Objectivity: Following the Evidence, Not a Narrative
The investigating officer must collect all evidence relevant to the offence, whether it supports the prosecution or exonerates the accused. Investigation is not a prosecution exercise; it is an impartial fact-finding process. Selective collection of evidence or deliberate suppression of exculpatory material is a serious violation of investigative duty.
6. The Duty to Conduct a Fair and Constitutionally Compliant Investigation
Every act of investigation must conform to constitutional values. An investigation that relies on coercion, fabrication, or illegal means is not merely ineffective; it is void, and it exposes the investigating officer to both departmental and criminal liability.
Power Without Limits Is Tyranny: The Legal and Constitutional Limitations on Police Investigation
1. Absolute Prohibition on Custodial Violence
Any use of coercion, threats, physical force, or third-degree methods during investigation is unconstitutional and illegal. Police officers who engage in custodial abuse are liable to face departmental action and criminal prosecution. The Constitution and the courts have made this prohibition absolute.
2. Judicial Supervision: The Magistrate as Watchdog
The Magistrate exercises continuous oversight over the investigation process, particularly with respect to remand and police custody. Courts have the power and the duty to refuse remand where police custody is not genuinely required, and to stop investigations that are malicious, arbitrary, or procedurally defective.
3. The Right to Life and Personal Liberty Under Article 21
Article 21 of the Constitution mandates that every investigation must be conducted in a manner that is fair, just, and reasonable. An investigation that violates the personal liberty of any person without due process of law is constitutionally impermissible, regardless of the gravity of the alleged offence.
4. Protection Against Compelled Self-Incrimination Under Article 20(3)
Article 20(3) of the Constitution guarantees that no person accused of an offence shall be compelled to be a witness against themselves. Consistent with this guarantee, the Bharatiya Sakshya Adhiniyam, 2023 provides that confessions made to police officers are generally inadmissible unless recorded before a Magistrate under proper conditions.
Landmark Judgments That Redefined Police Accountability in Criminal Investigation
The decision in D.K. Basu v. State of West Bengal (1997) 1 SCC 416 arose from a disturbing rise in police custody deaths and incidents of violence against persons in detention. The Supreme Court treated letters exposing police brutality as writ petitions and issued comprehensive guidelines that are now binding on every police officer across the country. The Court directed that every arrest must be accompanied by the preparation of an arrest memo, that a relative of the arrested person must be informed without delay, that the arrested person must undergo a medical examination, and that all relevant records must be maintained. The Court held unequivocally that custodial torture violates Article 21 of the Constitution and cannot be justified under any circumstances.
The decision in Joginder Kumar v. State of Uttar Pradesh (1994) 4 SCC 260 addressed a case where the police arrested the petitioner without valid reason and detained him without informing his relatives. The Supreme Court held that the mere legal power to arrest does not justify its exercise in every case. Police must affirmatively demonstrate the necessity of arrest. Every arrested person has the right to have a relative or friend informed of the arrest. Arrest must be based on genuine satisfaction of necessity, not mechanical compliance with the law.
From Fingerprints to Forensics: The Practical Evolution of Police Investigation in Modern India
The role of police in criminal investigation has transformed significantly over the past decade. Earlier, investigations depended almost entirely on witness statements and confessions, both of which were vulnerable to manipulation. In the modern era, scientific and digital methods have become indispensable investigative tools, and the law has kept pace with this transformation.
Under the Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023, substantial emphasis has been placed on technology-driven investigation. Police officers now routinely rely on CCTV footage, mobile data records, call detail records, DNA analysis, fingerprint examination, and forensic science techniques to establish facts and identify accused persons. Electronic records are expressly recognised as admissible evidence under the Bharatiya Sakshya Adhiniyam, 2023, which has strengthened the prosecution of cybercrime, financial fraud, and organised offences.
However, practical challenges persist. Police officers must ensure that every piece of evidence is collected lawfully and without violating constitutional safeguards. Any procedural irregularity, whether an illegal arrest, an improper search, or an inadmissible confession, can fatally weaken the prosecution's case at trial. The law provides the tools; the investigating officer must use them with both skill and integrity.
The Investigating Officer as the First Guardian of Justice: Conclusion
The police are not merely investigators. They are the starting point of the entire criminal justice process, and what happens at the investigation stage has a direct and irreversible impact on the outcome of the trial. Evidence collected properly and procedures followed diligently create the conditions for justice. Mistakes, misuse of power, or procedural shortcuts compromise not only individual cases but the credibility of the entire system.
The Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023 represent a serious legislative effort to make criminal investigation more organised, accountable, and technology-driven. But legislation is only as effective as the officers who implement it. The ultimate guardian of justice is not the statute book; it is the investigating officer who decides, at the scene of crime, how to act.
The balance must always be maintained. Police must possess sufficient powers to investigate crime effectively. Those powers must at the same time be firmly bounded by statutory limits and constitutional values. Only when that balance is achieved can citizens trust the system and believe that justice is being served fairly and without fear or favour.
Frequently Asked Questions (FAQs) on Police Investigation in India Under BNSS 2023
What is criminal investigation under the BNSS 2023? Criminal investigation is the process by which police collect evidence regarding the commission of an offence.

Police Investigation and the Law: Six Practical Applications That Shape Every Criminal Case
FIR as the Foundation of Every Criminal Case The First Information Report is not merely an administrative document. It is the foundation upon which the entire prosecution is built. A well-registered, accurate FIR ensures that the investigation proceeds on the right track and that the court has a reliable starting point for the trial.
Forensic Evidence as the Modern Cornerstone of Proof In the era of the Bharatiya Sakshya Adhiniyam, 2023, forensic evidence including DNA analysis, digital records, and CCTV footage has become the most reliable form of proof in serious criminal cases. Investigating officers trained in forensic evidence collection are now indispensable to effective prosecution.
Anticipating Legal Challenges During the Collection of Evidence Every step of evidence collection must be conducted with an eye on its eventual admissibility in court. Investigating officers must follow prescribed protocols for seizure, sealing, and documentation to ensure that evidence survives legal challenge during trial.
Custodial Safeguards as a Check on Investigative Excess The guidelines laid down in D.K. Basu v. State of West Bengal and the statutory provisions of the BNSS operate as a practical framework that every investigating officer must follow during arrest and detention. Compliance with these safeguards protects both the accused and the credibility of the investigation.
Judicial Oversight as a Real-Time Corrective Mechanism Magistrates exercise oversight at every critical stage of the investigation, from granting remand to examining the case diary. This judicial supervision acts as a real-time corrective mechanism that prevents investigative excess and ensures that the investigation remains within constitutional bounds.
Technology-Driven Investigation as the Future of Criminal Justice in India The formal recognition of electronic evidence under the Bharatiya Sakshya Adhiniyam, 2023 has fundamentally changed the landscape of criminal investigation. From cybercrime to financial fraud, digital forensics now plays a central role in establishing guilt or innocence, making technical competence as important as legal knowledge for the modern investigating officer.

Police Investigation and the Law: Six Practical Applications That Shape Every Criminal Case
FIR as the Foundation of Every Criminal Case The First Information Report is not merely an administrative document. It is the foundation upon which the entire prosecution is built. A well-registered, accurate FIR ensures that the investigation proceeds on the right track and that the court has a reliable starting point for the trial.
Forensic Evidence as the Modern Cornerstone of Proof In the era of the Bharatiya Sakshya Adhiniyam, 2023, forensic evidence including DNA analysis, digital records, and CCTV footage has become the most reliable form of proof in serious criminal cases. Investigating officers trained in forensic evidence collection are now indispensable to effective prosecution.
Anticipating Legal Challenges During the Collection of Evidence Every step of evidence collection must be conducted with an eye on its eventual admissibility in court. Investigating officers must follow prescribed protocols for seizure, sealing, and documentation to ensure that evidence survives legal challenge during trial.
Custodial Safeguards as a Check on Investigative Excess The guidelines laid down in D.K. Basu v. State of West Bengal and the statutory provisions of the BNSS operate as a practical framework that every investigating officer must follow during arrest and detention. Compliance with these safeguards protects both the accused and the credibility of the investigation.
Judicial Oversight as a Real-Time Corrective Mechanism Magistrates exercise oversight at every critical stage of the investigation, from granting remand to examining the case diary. This judicial supervision acts as a real-time corrective mechanism that prevents investigative excess and ensures that the investigation remains within constitutional bounds.
Technology-Driven Investigation as the Future of Criminal Justice in India The formal recognition of electronic evidence under the Bharatiya Sakshya Adhiniyam, 2023 has fundamentally changed the landscape of criminal investigation. From cybercrime to financial fraud, digital forensics now plays a central role in establishing guilt or innocence, making technical competence as important as legal knowledge for the modern investigating officer.

The First Responders of Justice: Understanding the Role of Police in Criminal Investigation Under BNSS 2023
Think of the police as the engine that powers the entire criminal justice machine. Without a proper investigation at the first stage, even the most well-drafted charge sheet and the most skilled courtroom advocacy cannot deliver justice to a victim. The police are not merely enforcers of law; they are the primary interface between the state and the citizen, between a crime committed and a conviction secured.
The criminal investigation system in India has undergone a historic transformation with the enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023. These landmark legislations have modernised the procedural framework, integrating technology and transparency into the investigation process while simultaneously reinforcing constitutional safeguards for the accused and victims alike. This article examines the role of police in criminal investigation in India in its entirety, covering its legal definition, governing statutory provisions, duties, limitations, landmark judgments, and practical applications in the modern era.
What Is Criminal Investigation? The Legal Definition and Its Scope Under BNSS 2023
Criminal investigation refers to the process by which police authorities collect evidence pertaining to the commission of an offence. It commences with the registration of a First Information Report and continues until the submission of the final police report before the Magistrate. Under the Bharatiya Nagarik Suraksha Sanhita, 2023, investigation encompasses all proceedings conducted by police officers for the purpose of collecting evidence, determining facts, and identifying the persons responsible for the commission of an offence.
The fundamental objective of criminal investigation is to ascertain the truth through lawful means. An investigation must be conducted in a fair, impartial, and objective manner, consistent with the constitutional safeguards guaranteed to every citizen. It is not an exercise in confirming a preconceived narrative; it is a structured, evidence-driven inquiry that must respect the rights of both the victim and the accused at every stage.
The Legal Architecture: Laws and Key Sections Governing Police Investigation in India
The investigative powers of the police in India are governed by a comprehensive legislative framework. The Bharatiya Nyaya Sanhita, 2023 defines substantive offences and their punishment. The Bharatiya Nagarik Suraksha Sanhita, 2023 lays down the procedural steps for investigation, arrest, and trial. The Bharatiya Sakshya Adhiniyam, 2023 determines the admissibility and validity of evidence gathered during investigation. Overarching all of these is the Constitution of India, which sets the non-negotiable boundaries within which all investigative action must remain.
The key sections under the BNSS that directly govern police investigation are as follows.
Section 173 deals with the registration of First Information Reports, including the introduction of e-FIR for electronic filing of complaints. The police cannot refuse to register an FIR where the information discloses the commission of a cognizable offence.
Section 175 confers upon police officers the authority to investigate cognizable offences without prior permission of the Magistrate, enabling immediate investigative action upon receipt of a complaint.
Section 180 governs the power of police to examine witnesses and record their statements during the course of investigation.
Section 35 provides the conditions under which an arrest without a warrant may be made, along with the procedural safeguards that must be observed.
Sections 105 and 185 regulate the power of search and seizure, requiring the police to follow established protocols to ensure that seized evidence retains its legal validity.
Section 193 requires the investigating officer to submit a final police report before the Magistrate upon completion of the investigation.
Under the Bharatiya Sakshya Adhiniyam, 2023, three provisions are of particular relevance to police investigations. Section 22 renders confessions obtained through inducement, threat, coercion, or promise inadmissible in criminal proceedings. Section 23 provides that confessions made directly to police officers are generally inadmissible as evidence. Sections 61 to 63 establish the framework for the admissibility of electronic and digital records, recognising them as valid evidence carrying the same weight as paper documents and laying down conditions for the admissibility of computer-generated evidence.
Investigation in Action: A Step-by-Step Real-World Scenario Explained
To understand how criminal investigation operates in practice, consider a concrete scenario. A jeweller reports to the police that his shop was broken into during a public holiday and that cash along with jewellery has been stolen. On receipt of the complaint, the police register an FIR under the relevant provisions of the Bharatiya Nagarik Suraksha Sanhita, 2023.
The investigating officer visits the shop to examine the crime scene. Photographs are taken, fingerprints are lifted, and CCTV footage from nearby establishments is collected and preserved. Statements are recorded from neighbours and employees who may have observed suspicious activity. If a suspect is identified, the police may proceed to arrest, strictly following the procedural safeguards prescribed under law.
If electronic evidence is available, it is collected and preserved in accordance with the Bharatiya Sakshya Adhiniyam, 2023 to ensure its admissibility before the court. Every step of this process, from FIR registration to the final report, is governed by law and must be executed with precision. A procedural error at any stage can compromise the entire prosecution.
The Six Core Duties of Police in Criminal Investigation Every Citizen Should Know
1. The Duty to Preserve Evidence: The Chain of Custody Cannot Be Broken
It is the primary duty of the investigating officer to ensure that all evidence collected at the scene of crime is properly sealed, labelled, and documented. Maintaining an unbroken chain of custody is essential to the admissibility of evidence before the court. Any gap or irregularity in the preservation of evidence can allow the defence to challenge its authenticity.
2. The Duty to Safeguard the Rights of the Accused: Arrest Is Not Punishment
The police are duty-bound to inform every arrested person of the grounds of their arrest, provide them access to legal counsel without delay, and produce them before a Magistrate within twenty-four hours of arrest. These are not procedural formalities; they are constitutional obligations that directly reflect the right to personal liberty guaranteed under Article 21.
3. The Duty to Maintain a Case Diary: Transparency at Every Step
During the course of investigation, the investigating officer must maintain a case diary recording each procedural step taken. This document serves as a contemporaneous record of the investigation, ensures transparency and accountability, and is available to the court for scrutiny during trial.
4. The Duty to Register the FIR: No Complaint Can Be Turned Away
The police are legally obligated to register a First Information Report wherever a complaint discloses the commission of a cognizable offence. Refusal to register an FIR is not merely a procedural lapse; it is an abdication of statutory responsibility that directly denies the victim access to justice.
5. The Duty of Objectivity: Following the Evidence, Not a Narrative
The investigating officer must collect all evidence relevant to the offence, whether it supports the prosecution or exonerates the accused. Investigation is not a prosecution exercise; it is an impartial fact-finding process. Selective collection of evidence or deliberate suppression of exculpatory material is a serious violation of investigative duty.
6. The Duty to Conduct a Fair and Constitutionally Compliant Investigation
Every act of investigation must conform to constitutional values. An investigation that relies on coercion, fabrication, or illegal means is not merely ineffective; it is void, and it exposes the investigating officer to both departmental and criminal liability.
Power Without Limits Is Tyranny: The Legal and Constitutional Limitations on Police Investigation
1. Absolute Prohibition on Custodial Violence
Any use of coercion, threats, physical force, or third-degree methods during investigation is unconstitutional and illegal. Police officers who engage in custodial abuse are liable to face departmental action and criminal prosecution. The Constitution and the courts have made this prohibition absolute.
2. Judicial Supervision: The Magistrate as Watchdog
The Magistrate exercises continuous oversight over the investigation process, particularly with respect to remand and police custody. Courts have the power and the duty to refuse remand where police custody is not genuinely required, and to stop investigations that are malicious, arbitrary, or procedurally defective.
3. The Right to Life and Personal Liberty Under Article 21
Article 21 of the Constitution mandates that every investigation must be conducted in a manner that is fair, just, and reasonable. An investigation that violates the personal liberty of any person without due process of law is constitutionally impermissible, regardless of the gravity of the alleged offence.
4. Protection Against Compelled Self-Incrimination Under Article 20(3)
Article 20(3) of the Constitution guarantees that no person accused of an offence shall be compelled to be a witness against themselves. Consistent with this guarantee, the Bharatiya Sakshya Adhiniyam, 2023 provides that confessions made to police officers are generally inadmissible unless recorded before a Magistrate under proper conditions.
Landmark Judgments That Redefined Police Accountability in Criminal Investigation
The decision in D.K. Basu v. State of West Bengal (1997) 1 SCC 416 arose from a disturbing rise in police custody deaths and incidents of violence against persons in detention. The Supreme Court treated letters exposing police brutality as writ petitions and issued comprehensive guidelines that are now binding on every police officer across the country. The Court directed that every arrest must be accompanied by the preparation of an arrest memo, that a relative of the arrested person must be informed without delay, that the arrested person must undergo a medical examination, and that all relevant records must be maintained. The Court held unequivocally that custodial torture violates Article 21 of the Constitution and cannot be justified under any circumstances.
The decision in Joginder Kumar v. State of Uttar Pradesh (1994) 4 SCC 260 addressed a case where the police arrested the petitioner without valid reason and detained him without informing his relatives. The Supreme Court held that the mere legal power to arrest does not justify its exercise in every case. Police must affirmatively demonstrate the necessity of arrest. Every arrested person has the right to have a relative or friend informed of the arrest. Arrest must be based on genuine satisfaction of necessity, not mechanical compliance with the law.
From Fingerprints to Forensics: The Practical Evolution of Police Investigation in Modern India
The role of police in criminal investigation has transformed significantly over the past decade. Earlier, investigations depended almost entirely on witness statements and confessions, both of which were vulnerable to manipulation. In the modern era, scientific and digital methods have become indispensable investigative tools, and the law has kept pace with this transformation.
Under the Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023, substantial emphasis has been placed on technology-driven investigation. Police officers now routinely rely on CCTV footage, mobile data records, call detail records, DNA analysis, fingerprint examination, and forensic science techniques to establish facts and identify accused persons. Electronic records are expressly recognised as admissible evidence under the Bharatiya Sakshya Adhiniyam, 2023, which has strengthened the prosecution of cybercrime, financial fraud, and organised offences.
However, practical challenges persist. Police officers must ensure that every piece of evidence is collected lawfully and without violating constitutional safeguards. Any procedural irregularity, whether an illegal arrest, an improper search, or an inadmissible confession, can fatally weaken the prosecution's case at trial. The law provides the tools; the investigating officer must use them with both skill and integrity.
The Investigating Officer as the First Guardian of Justice: Conclusion
The police are not merely investigators. They are the starting point of the entire criminal justice process, and what happens at the investigation stage has a direct and irreversible impact on the outcome of the trial. Evidence collected properly and procedures followed diligently create the conditions for justice. Mistakes, misuse of power, or procedural shortcuts compromise not only individual cases but the credibility of the entire system.
The Bharatiya Nagarik Suraksha Sanhita, 2023 and the Bharatiya Sakshya Adhiniyam, 2023 represent a serious legislative effort to make criminal investigation more organised, accountable, and technology-driven. But legislation is only as effective as the officers who implement it. The ultimate guardian of justice is not the statute book; it is the investigating officer who decides, at the scene of crime, how to act.
The balance must always be maintained. Police must possess sufficient powers to investigate crime effectively. Those powers must at the same time be firmly bounded by statutory limits and constitutional values. Only when that balance is achieved can citizens trust the system and believe that justice is being served fairly and without fear or favour.
