Strategies and Legal Boundaries in the Interrogation of Accused Individuals

When a person is arrested and brought in for questioning, what happens inside that interrogation room is far from a free-for-all. India’s criminal justice system draws a clear boundary between permissible investigative questioning and coercive conduct that violates an accused’s fundamental rights. This boundary is not just a matter of procedure – it determines whether anything said during interrogation can actually be used in court. Understanding how interrogation works, what the law permits, and what it absolutely prohibits is essential for anyone studying criminal law or involved in the justice process.

What interrogation means in the criminal justice context 🔗

Interrogation is the formal questioning of a person by law enforcement to gather information relevant to a crime under investigation. In India, this process is governed primarily by the Code of Criminal Procedure, 1973 (CrPC) – now largely replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) – along with the Indian Evidence Act and constitutional guarantees. The objective is to elicit truthful information that aids the investigation. However, the method by which that information is obtained is heavily regulated, because the law recognises that the power imbalance in a custodial setting creates conditions ripe for abuse.

A critical starting point: the police in India have no general power to detain anyone for questioning unless that person has been lawfully arrested. Voluntary questioning without arrest is permissible, but compelling someone to come to a police station solely for interrogation – without following due process – is not.

Constitutional protections that shape interrogation 🔗

Three foundational constitutional provisions directly govern how interrogation must be conducted.

Article 20(3) – the right against self-incrimination 🔗

Article 20(3) of the Constitution grants every accused person the right not to testify against themselves. No one can be compelled to furnish a statement that incriminates them. This right was extensively examined in the landmark case of Nandini Satpathy v. P.L. Dani, where the Supreme Court held that no person can be forced to answer questions, and the accused has the right to remain silent during interrogation. This is the closest India comes to a statutory “right to silence,” even though the right itself is derived from constitutional interpretation rather than an explicit legislative provision.

Article 21 – right to life and personal liberty 🔗

Article 21 guarantees that no person shall be deprived of their life or personal liberty except through a fair and lawful procedure. Any form of physical or psychological torture during interrogation – designed to extract a confession – is a direct violation of this article. The Supreme Court in D.K. Basu v. State of West Bengal (1997) made this unambiguous: using any form of torture to extract information is neither right nor fair, and is impermissible as it offends Article 21.

Article 22 – right to legal representation 🔗

Article 22(1) provides that no arrested person shall be denied the right to consult a legal practitioner of their choice. This right kicks in from the moment of arrest and extends into the interrogation room. Section 41D of the CrPC further specifies that when a person is arrested and interrogated by the police, they are entitled to meet an advocate of their choice during interrogation, though not throughout the entire interrogation. This qualified right – present but not absolute – reflects the law’s attempt to balance investigative effectiveness with the accused’s need for legal counsel.

The D.K. Basu guidelines: a rulebook for interrogation 🔗

The Supreme Court’s 1997 judgment in D.K. Basu v. State of West Bengal remains the most comprehensive judicial pronouncement on how the police must conduct arrests and interrogations. The guidelines issued in this case are mandatory and non-negotiable, applying not just to state police but to all government agencies including the CBI, BSF, and intelligence organisations. Some key directives specifically relevant to interrogation include:

• Identification: All police personnel carrying out arrests and handling interrogation must wear clear, visible name tags with their designation.
• Register of interrogating officers: The particulars of every police official conducting an interrogation must be recorded in a register maintained at the place of detention.
• Arrest memo: A formal memo must be prepared at the time of arrest, attested by a witness, and countersigned by the arrested person.
• Family notification: The arrested person must be informed of their right to have a family member or friend notified of the arrest.
• Access to lawyer: The arrestee may meet their lawyer during interrogation, though not continuously throughout the process.
• Medical examination: The detained person must be medically examined upon arrest and every 48 hours thereafter.

Non-compliance with these guidelines can expose the officer to departmental action and even contempt of court proceedings.

How confessions and statements are legally recorded 🔗

One of the most legally significant moments in any interrogation is when the accused makes a confession or a statement. Indian law draws a sharp line between statements made to police officers and those made before a Magistrate.

Confessions to the police – generally inadmissible 🔗

A confession made to a police officer is excluded from admissibility under the Indian Evidence Act. The law recognises that a person in police custody is inherently in a vulnerable state – surrounded by fear, pressure, and the possibility of coercion. To admit such confessions freely would create a perverse incentive for custodial abuse. The only exception is when the confession leads to the discovery of a fact, in which case that factual portion may be admissible.

Recording confessions before a Magistrate – Section 164 CrPC / Section 183 BNSS 🔗

Section 164 of the CrPC (now Section 183 of the BNSS) empowers a Judicial Magistrate or Metropolitan Magistrate to record confessions and statements during the course of an investigation. The purpose of routing confessions through a Magistrate is to ensure they are made freely and voluntarily, without any form of coercion or undue influence. Several procedural safeguards apply:

• The Magistrate must inform the accused that they are not obliged to make a confession, and that if they do, it may be used against them.
• The accused must be given time to reflect before the confession is recorded.
• If the accused refuses to confess, the Magistrate must not return them to police custody; they must be sent to judicial remand instead.
• The police are not permitted to be present during the recording of the confession.
• If the accused later claims the confession was coerced, the court will scrutinise the Magistrate’s certificate and may examine the Magistrate as a witness.

A confession recorded under this procedure, if proven voluntary, is admissible under the Indian Evidence Act. However, it cannot be used on its own to secure a conviction – it must be corroborated by other evidence. Importantly, a court cannot selectively accept the incriminating portions of a confession while rejecting the exculpatory parts; the confession must be treated as a whole.

Scientific interrogation techniques: where does the law draw the line? 🔗

Modern investigations sometimes involve forensic aids such as narco-analysis (administering a “truth serum”), polygraph (lie detector) tests, and brain-mapping. Indian courts have had to squarely address whether these techniques can be used on the accused.

The definitive answer came in Selvi v. State of Karnataka (2010), where a three-judge bench of the Supreme Court held that involuntary administration of narco-analysis, polygraph, and brain-mapping techniques on suspects, accused persons, or witnesses is unconstitutional. Forcing an accused to undergo any of these tests without their consent violates Article 20(3) (self-incrimination) and Article 21 (personal liberty). Even if information is obtained through these tests with the person’s consent, the results themselves cannot be treated as admissible confessions in court, because the subject’s mental faculties are compromised during the test.

This position was reaffirmed in Amlesh Kumar v. State of Bihar (2025), where the Supreme Court reiterated that no lie-detector or narco test can be administered without the accused’s free, informed consent, recorded before a Judicial Magistrate. The Court also required that the accused have access to a lawyer before consenting, and that the actual testing be done by an independent agency in the presence of counsel.

Key rights of the accused during interrogation: a summary 🔗

Putting all the legal provisions together, an accused person being interrogated in India is entitled to the following core protections:

• Right to be informed of grounds of arrest under Article 22(1) and Section 50 of the CrPC.
• Right to remain silent derived from Article 20(3) and the principle affirmed in Nandini Satpathy.
• Right to legal counsel during interrogation under Section 41D of the CrPC and Article 22(1).
• Right to free legal aid if the accused cannot afford a lawyer, as upheld in Sukh Das v. Union Territory of Arunachal Pradesh – and failure to provide this aid can vitiate the entire trial.
• Right to medical examination under Section 54 of the CrPC, on the accused’s request.
• Right against torture – no third-degree methods, psychological coercion, or scientific testing without free and informed consent.
• Right to be produced before a Magistrate within 24 hours of arrest under Section 57 of the CrPC.

The gap between law and practice 🔗

India’s legal framework for interrogation is robust on paper. However, the reality of custodial practice tells a different story. Custodial deaths, torture, and coerced confessions remain documented problems in the country’s criminal justice system. The Supreme Court’s direction in D.K. Basu to install CCTV cameras in all police stations – though repeatedly emphasised – has not been uniformly implemented. The gap between the court’s guidelines and actual police conduct continues to give rise to violations that undermine both justice and the rights of the accused. Systemic reform – through better training, independent oversight, and accountability mechanisms – remains the most pressing challenge.

The legal architecture surrounding interrogation reflects a fundamental principle: the purpose of investigation is to discover truth, not to manufacture it through pressure. Any statement or confession extracted through coercion is not only a violation of the accused’s rights – it is also unreliable evidence that pollutes the trial process.

What do you think? If a confession recorded before a Magistrate is later alleged to have been made under police pressure, should the burden of proving voluntariness lie with the prosecution or with the accused? And given the persistent gap between D.K. Basu’s guidelines and ground-level policing, what structural reforms do you think would be most effective in curbing custodial coercion in India?
