NDPS Arrests Under Constitutional Scrutiny: Supreme Court Rejects Artificial Distinction Between Detention and Arrest

The Supreme Court has reaffirmed that the constitutional 24-hour deadline for producing a person before a magistrate begins when that person’s liberty is actually curtailed, not when an investigating agency later prepares a formal arrest memo.

In a major ruling concerning investigations under the Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act), the Court held that authorities cannot keep a person under their control for search, questioning, seizure formalities or investigation and postpone the constitutional safeguard by describing the person as merely “intercepted” or “detained for enquiry.”

The judgment strengthens the protection contained in Article 22(2) of the Constitution and makes clear that statutory procedure under the NDPS Act cannot override the right to prompt judicial scrutiny of custody.

The issue before the Court

The matter arose from an NDPS investigation involving the alleged recovery of methamphetamine tablets from a commercial vehicle and related baggage. During the operation, enforcement officials intercepted multiple individuals and recovered suspected contraband. The persons were kept with the search team while officials conducted field testing, weighing, seizure documentation and further search procedures.

The investigating authority maintained that the persons were formally arrested only the next day, after the completion of search, seizure, questioning and paperwork. They were subsequently produced before a magistrate within 24 hours of the formal time recorded in the arrest memoranda.

The defence challenged this timeline. It argued that the persons had been under the effective control of the enforcement team from the time of interception and were not free to leave. Therefore, the 24-hour period under Article 22(2) had begun at the time of actual restraint, not at the later time shown as formal arrest.

The Supreme Court accepted this argument.

Article 22(2): a mandatory constitutional safeguard

Article 22(2) requires every person who is arrested and detained in custody to be produced before the nearest magistrate within 24 hours. The Constitution permits only one exclusion while calculating this period: the time necessary to travel from the place of arrest to the magistrate’s court.

The Court described the safeguard as absolute and mandatory. It exists to ensure that an independent judicial officer can promptly examine whether custody is lawful and whether further detention should be authorised.

Importantly, the Court held that the following cannot be excluded from the 24-hour calculation:

• time spent conducting search and seizure;
• questioning or interrogation;
• preparation of arrest records and other paperwork;
• weighing, sampling, testing, packaging or inventory of seized material;
• administrative processes; and
• internal logistical delays unrelated to the journey to the magistrate.

Actual restraint, not paperwork, determines when custody begins

The central principle of the ruling is that arrest for the purpose of Article 22(2) begins when a person’s freedom of movement is effectively restrained by an authority having coercive power.

The Court explained that the true test is straightforward: was the person free to leave? If the answer is no, and the person was under the control of investigating officers in connection with a suspected offence, the person was in custody.

A later entry in an arrest memo cannot rewrite the factual point at which the State took control of an individual’s liberty. The Court rejected attempts to draw a technical distinction between “detention” and “arrest” where the result would be to delay constitutional protection.

The judgment emphasises that the Constitution does not recognise an unregulated period in which an individual may be held for investigation without the 24-hour safeguard beginning to run.

No “investigative buffer zone” in NDPS cases

The investigating authority argued that the period before the formal arrest was required to comply with procedures under the NDPS Act and the Narcotic Drugs and Psychotropic Substances (Seizure, Storage, Sampling and Disposal) Rules, 2022. It contended that search, seizure, classification, weighing and packaging needed to be completed in the presence of the persons from whose possession the substances were allegedly recovered.

The Supreme Court accepted that these procedures may be mandatory and important for evidentiary integrity. However, it held that compliance with them does not suspend Article 22(2).

The Court rejected the concept of an “investigative buffer zone” in which a person may be under agency control for fact-gathering purposes but the constitutional 24-hour countdown remains on hold. Such an approach, the Court said, is unconstitutional because it would permit authorities to curtail liberty without timely judicial oversight.

The NDPS Act authorises search, seizure, detention and arrest in specified circumstances. But its procedural provisions must be implemented consistently with the Constitution. A special statute cannot reduce the scope of a fundamental right.

The Court’s finding on the custody timeline

On the facts before it, the Court found that the detained persons came under the control of the search team at 2:00 pm on the first day of the operation. Their liberty was curtailed from that point, and the constitutional 24-hour period began then.

They were required to be produced before a magistrate by 2:00 pm on the following day, subject only to necessary travel time to court. However, they were produced at 4:45 pm.

The Court held that this constituted a clear breach of Article 22(2). The later formal recording of arrest could not alter the real point at which custody began.

As a result, the arrest was vitiated and detention beyond the 24-hour constitutional limit was held to be illegal and unconstitutional.

Section 58 BNSS: custody must also be reasonable

The ruling also addresses Section 58 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which carries forward the principle earlier found in Section 57 of the Code of Criminal Procedure.

This provision imposes two separate safeguards:

1. A person detained without warrant cannot be held beyond 24 hours without a magistrate’s authority, excluding only travel time to court.
2. Even within that 24-hour ceiling, detention must not continue longer than is reasonable in the circumstances.

In this case, the search and seizure procedures had reportedly concluded by 5:00 pm on the first day. The formal arrest, however, was recorded only around 11:00 am the next day. The Court found no adequate explanation for this approximately 18-hour interval.

It held that such a lengthy period of custody without judicial oversight could not be considered reasonable. The ruling therefore makes clear that compliance with the outer 24-hour limit alone is not enough. Courts must also examine whether the actual period of custody was justified.

Why the decision matters for NDPS bail

Bail in NDPS cases involving commercial quantities is usually governed by the stringent conditions in Section 37 of the NDPS Act. Ordinarily, a court must be satisfied that there are reasonable grounds to believe that the accused is not guilty and is unlikely to commit an offence while on bail.

The Supreme Court, however, reaffirmed that restrictions under a special criminal law cannot override fundamental rights. Where detention violates Article 21 or Article 22 of the Constitution, constitutional liberty takes precedence over statutory restrictions on bail.

Accordingly, the Court set aside the refusal of bail and directed release on bail, subject to conditions fixed by the competent Special Court.

Responsibilities of investigating authorities

The judgment imposes clear obligations on enforcement and investigating authorities:

• Record the real time of restraint: Authorities must recognise the moment a person ceases to be free to leave.
• Produce the person within 24 hours: The deadline runs from actual detention, not from a later arrest entry.
• Exclude only travel time: Search, seizure, inventory, questioning and paperwork do not extend the deadline.
• Avoid unreasonable custody: Even before the 24-hour period expires, detention must remain necessary and proportionate.
• Follow procedure without defeating liberty: NDPS safeguards may be completed, but not by postponing judicial scrutiny of a person who is already under official control.

Responsibilities of magistrates at first production

The Court also underscored that remand cannot be a mechanical exercise. When a detained person is first produced, the magistrate must independently assess the actual chronology of custody.

The magistrate must determine:

• the date and time when the person’s liberty was first curtailed;
• whether production occurred within 24 hours of that time, excluding only necessary travel time; and
• whether the period of detention was reasonable in the circumstances.

If the 24-hour period has been crossed, the person must be released from custody. Even where production is technically within 24 hours, the magistrate may decline remand if the detention was longer than reasonably necessary.

High Court approaches disapproved

The Supreme Court disapproved earlier views that treated search-related restraint or investigative detention as separate from arrest for the purpose of Article 22(2). Those approaches had allowed the constitutional clock to begin only after the conclusion of search and seizure procedures or after formal arrest was recorded.

The Court held that this interpretation was incompatible with the constitutional protection of personal liberty. It warned that concepts such as a “short investigatory hold” or a temporary disruption of liberty create uncertainty and risk enabling unrecorded custody.

The Court’s position is clear: there is no constitutionally recognised category of custody in which a person is not free to leave but Article 22(2) does not apply.

Stronger protection against unrecorded custody

The ruling is closely linked to the purpose of Article 22(2): preventing unlawful detention, custodial abuse and coercive interrogation before judicial oversight begins. The Court referred to established concerns that the most serious violations of human rights can occur during periods when a person is held but not formally shown as arrested.

By focusing on the factual loss of liberty rather than labels used in official documents, the decision strengthens protections against delayed arrest records and unaccounted custody. It also reinforces the magistrate’s role as an independent safeguard against unlawful detention.

Key legal principles from the ruling

• The 24-hour period under Article 22(2) starts when a person is actually detained and loses freedom to leave.
• A formal arrest memo does not determine the beginning of constitutional custody.
• Only necessary travel time from the place of arrest to the magistrate’s court may be excluded.
• NDPS search, seizure, sampling, weighing, questioning and documentation do not pause the 24-hour clock.
• Authorities cannot create an investigative “buffer zone” outside constitutional safeguards.
• Detention must be reasonable even if it remains within 24 hours.
• Magistrates must identify the actual time of detention before authorising remand.
• A breach of the 24-hour rule makes continued custody illegal and requires release.
• Fundamental rights under Articles 21 and 22 prevail over statutory bail restrictions where constitutional safeguards are violated.

The judgment establishes a firm rule for all criminal investigations: once the State effectively restrains a person’s liberty, constitutional scrutiny begins immediately, and the person must be produced before a magistrate within 24 hours.
