‘Investigator Cannot Be Punisher’: Court Raps CBI Over Custodial Torture — Article 21 Explained

CURRENT AFFAIRS | 8 JULY 2026

In a sharply worded order that has quickly become required reading for law aspirants, a Delhi court has reminded the country’s premier investigating agency of a first principle of criminal justice: an investigator cannot double up as a punisher. The Special Judge at the Rouse Avenue Court pulled up the Central Bureau of Investigation (CBI) over allegations of custodial torture, holding that “no investigating agency is permitted to assume the dual role of investigator and punisher.” The observation, anchored firmly in Article 21 of the Constitution, is a textbook illustration of how the right to life and personal liberty operates inside a police lock-up.

What Happened

The accused had been arrested on 16 June in a multi-crore case involving counterfeit medicines and alleged bribery. Soon after, he alleged that he had been subjected to custodial torture — severe beatings, with injuries to his left eye and thigh. Crucially, these were not bare allegations. Medico-legal certificate (MLC) records dated 19.06.2026 and 20.06.2026 corroborated the injuries, giving the claims prima facie weight before the court.

Reacting to this material, the court directed that the accused be medically examined at Safdarjung Hospital and used the occasion to deliver a stern reminder about the constitutional limits on state power. “Custodial violence is one of the gravest assaults on the rule of law,” the judge observed, adding that it “strikes at the very foundation of a constitutional democracy founded upon the guarantee of life, liberty and human dignity under Article 21.” Punishment, the court underlined, can be imposed only by a competent court after due process of law — never by an agency tasked merely with gathering evidence.

Why “Investigator Cannot Be Punisher” Matters

The phrase captures the separation of functions that keeps criminal justice fair. An investigating agency’s job is to collect evidence, examine witnesses, and file a charge sheet. Deciding guilt and imposing punishment belongs exclusively to a court, after a trial in which the accused can defend himself. If the agency itself starts inflicting pain to extract confessions or to “teach a lesson,” it collapses these separate roles into one — and in doing so, destroys the presumption of innocence, the very idea that a person is innocent until proven guilty.

This is why the court’s language was so emphatic. Custodial violence is not just an assault on one individual; it is an attack on the rule of law itself. When the machinery of the state tortures a person it has arrested, it signals that power can be exercised without accountability — the exact opposite of what a constitutional democracy stands for.

The Guiding Precedents

Indian courts did not arrive at this position overnight. The landmark case is D.K. Basu v. State of West Bengal (1997), in which the Supreme Court laid down 11 binding guidelines governing arrest and custody — including that arresting officers must wear clear identification, prepare a memo of arrest attested by a witness, inform a relative or friend of the arrest, and ensure that the arrestee is medically examined every 48 hours in custody. These guidelines were a direct judicial response to the epidemic of custodial deaths and torture.

Equally important is Nilabati Behera v. State of Orissa (1993), where the Court held that the state is liable to pay compensation for the violation of fundamental rights caused by custodial death — establishing that monetary compensation is a public-law remedy under Articles 32 and 226, distinct from a private civil suit. The Prakash Singh (2006) police-reform directions, which pushed for insulating investigation from external pressure and creating accountability mechanisms, complete the picture of a judiciary steadily trying to civilise policing.

The Statutory Angle: BNSS and Arrest Procedure

Beyond the Constitution, arrest procedure is now governed by the Bharatiya Nagarik Suraksha Sanhita (BNSS), which replaced the old Code of Criminal Procedure. Section 41 BNSS lays down when a police officer may arrest without a warrant and requires officers to record reasons for arrest, echoing the safeguards developed by the courts. The statutory framework reinforces what the Constitution demands — that arrest is a serious deprivation of liberty which must be justified, documented, and subject to judicial oversight, not an occasion for extra-legal punishment.

The Bigger Picture

Custodial torture remains one of the most persistent human-rights problems in Indian policing, precisely because it happens behind closed doors where evidence is hard to gather. That is why prima facie corroboration — here, the MLC records — is so significant: it moved the allegation from the realm of “he said, they said” into something a court could act upon. It also shows the practical value of the D.K. Basu safeguard requiring periodic medical examination of detainees; documented injuries create a paper trail that agencies cannot easily wish away.

The order does not decide the guilt or innocence of the accused in the underlying counterfeit-medicine case — that will be settled at trial. What it does is police the policing: it insists that however serious the charge, the person accused retains the full protection of Article 21. In a constitutional democracy, the ends never justify torturous means.

How Article 21 Grew to Cover Torture

It is worth understanding why torture falls within Article 21 at all, since the text of the Article says nothing about it. The expansion happened through judicial interpretation. In Maneka Gandhi v. Union of India (1978), the Supreme Court held that the “procedure established by law” under Article 21 must be fair, just and reasonable — not arbitrary or oppressive. This transformed Article 21 from a narrow protection against unlawful detention into a broad guarantee of dignified treatment by the state. Once dignity became part of the right to life, custodial torture — the ultimate assault on dignity — became a clear constitutional violation. The Delhi court’s order sits squarely in this lineage: it treats the beating of a detainee not as a mere disciplinary lapse but as a breach of the Constitution’s core promise.

This is also why remedies for custodial abuse operate on multiple levels. A victim may seek compensation under public law (as in Nilabati Behera), pursue criminal prosecution of the officers involved, and rely on constitutional courts to issue directions ensuring medical examination and safe custody — exactly what the Rouse Avenue court did here. The layered nature of these remedies is a favourite testing ground for legal-reasoning passages, because it forces students to distinguish between what a criminal court, a constitutional court, and a civil court can each do.
