Case Summary: Amlesh Kumar v. State of Bihar (2025)

Case Details

Title: Amlesh Kumar v. State of Bihar (2025)
Citation: SLP (Crl.) No. 5392 of 2024
Bench: Justice Sanjay Karol and Justice Prasanna B. Varale
Date of Judgment: 9 June 2025

I. Issues

1. Whether the High Court has the power to accept the submission of conducting a narco-analysis on the accused and witnesses while hearing a bail application?
2. Whether the report of the narco-analysis can form the sole basis of conviction in a criminal case?
3. Whether an accused has an absolute right to voluntarily seek a narco-analysis test?
4. Whether the accused can be compelled to undergo narco-analysis without their free consent?

II. Facts

On 24 August 2022, an FIR was registered at Mahua Police Station, Vaishali District, against Amlesh Kumar and his family members under Sections 341, 342, 323, 363, 364, 498A, 504, 506, and 34 of the Indian Penal Code, 1860,[1] accusing them of offences including dowry harassment, wrongful confinement, cruelty, kidnapping, and criminal intimidation. The complaint was filed by the sister of Amlesh’s wife, alleging that after their marriage in December 2020, Amlesh and his family repeatedly demanded dowry and physically assaulted her sister, and that on 22 August 2022, Amlesh had informed her that his wife had run away from the matrimonial home.

Amlesh, however, stated that his wife disappeared during a bus journey to Ayodhya on 21 August 2022 after she got off for a washroom break and did not return. He filed a missing person complaint on 28 August 2022. The wife remained missing, and co-accused persons reportedly confessed that she had been thrown into the Saryu River.

In the criminal proceedings, while Amlesh’s parents and brothers were granted bail by the Patna High Court, his bail application was rejected by the Sessions Court on 1 August 2023. He then approached the Patna High Court for regular bail. During those proceedings, the Sub-Divisional Police Officer suggested that a narco-analysis test be conducted on the accused and key witnesses. The High Court accepted this suggestion and postponed the bail proceedings until the narco-analysis results were available. Amlesh subsequently challenged this acceptance before the Supreme Court, contending that the narco-analysis test violated his right to life and personal liberty under Article 21 of the Constitution of India.[2]

III. Summary of Contentions

Petitioner’s Contentions:

1. The Patna High Court erred in accepting and acting upon the investigating officer’s suggestion to subject the accused and witnesses to narco-analysis during the course of investigations. This constitutes a direct breach of Articles 20(3)[3] and 21 of the Constitution of India, as authoritatively held in Selvi v. State of Karnataka.[4]
2. Narco-analysis tests are inherently coercive, as they operate by interfering with the conscious mind of a person and supplanting free will. Any statement made under such circumstances constitutes a violation of the right against self-incrimination under Article 20(3) of the Constitution.
3. The jurisdiction of a court under Section 439 of the Code of Criminal Procedure[5] is confined to specific bail-related considerations. It is therefore impermissible for a court at that stage to entertain, endorse, or facilitate any invasive method of investigation falling outside the scope of bail proceedings.
4. Confessional statements recorded by co-accused, along with any report arising from narco-analysis, are insufficient in themselves to ground a conviction and cannot be treated as the sole basis for establishing guilt against an accused person.

Respondent’s Contentions:

1. Narco-analysis constitutes an effective and legitimate investigative method, particularly indispensable for uncovering the truth in serious criminal matters involving offences such as murder and dowry harassment.
2. The Patna High Court had merely taken on record the investigating officer’s assurance regarding the proposed conduct of narco-analysis and had not issued any binding or mandatory direction compelling the accused to undergo the test.
3. Narco-analysis, when undertaken with the free and informed consent of the subject and administered under proper procedural safeguards, does not amount to a violation of any fundamental right guaranteed under the Constitution of India.

IV. Final Decision and Underlying Legal Principles

Final Decision:

The Supreme Court allowed the appeal and quashed the Patna High Court’s order, holding that judicial acceptance of a narco-analysis proposal during bail proceedings directly violates Articles 20(3) and 21 of the Constitution. The Court directed the Appellant’s bail application to be reconsidered afresh on its legal merits, entirely free from the influence of the narco-analysis proposal.

Ratio Decidendi:

The ratio decidendi of this case rests on three foundational pillars:

1. On Involuntary Narco-Analysis: A court’s acceptance of a narco-analysis proposal during bail proceedings, even without issuing an explicit mandatory direction, amounts to indirect judicial endorsement of an unconstitutional investigative technique. Such acceptance violates the right against self-incrimination under Article 20(3) and the right to personal liberty and mental privacy under Article 21, as settled in Selvi v. State of Karnataka (2010).
2. On Evidentiary Value: Narco-analysis results, whether voluntary or otherwise, cannot constitute the sole basis for conviction and must be independently corroborated. Only such facts as are subsequently discovered therefrom are admissible under Section 27 of the Indian Evidence Act.[6]
3. On Bail Jurisdiction: Bail proceedings under Section 439 CrPC are limited in scope. A court exercising such jurisdiction cannot endorse or facilitate intrusive investigative methods, as doing so exceeds judicial authority and converts the bail hearing into a mini-trial.

V. Analysis and Precedential Consistency

The Supreme Court’s decision in Amlesh Kumar v. State of Bihar is constitutionally sound and well-reasoned. The Court was correct in holding that the High Court’s passive acceptance of the narco-analysis proposal amounted to indirect judicial endorsement of an unconstitutional act, thereby violating Articles 20(3) and 21 of the Constitution. The Court was equally correct in confining bail proceedings under Section 439 CrPC to their limited scope and in holding that narco-analysis results, even voluntary ones, cannot solely ground a conviction without independent corroboration.

However, the judgment leaves two significant questions unresolved: whether the prescribed safeguards for voluntary narco-analysis are practically enforceable given India’s ground realities, and whether completely foreclosing narco-analysis at the investigative stage may, in certain extreme cases, compromise the victim’s right to justice. These are tensions that future jurisprudence must inevitably address.

The judgment is largely consistent with existing precedents:

1. It reaffirms Selvi v. State of Karnataka (2010) by upholding the prohibition on involuntary narco-analysis.[7]
2. It aligns with Sangitaben Shaileshbhai Datana v. State of Gujarat (2018) by disapproving the use of bail proceedings to endorse invasive investigative techniques.[8]
3. It reinforces Manoj Kumar Soni v. State of M.P. (2023) by mandating independent corroboration of disclosure statements.[9]
4. It builds upon Vinobhai v. State of Kerala (2025)[10] by confining admissibility strictly to facts independently discovered under Section 27 of the Indian Evidence Act, making this judgment a meaningful constitutional extension rather than a mere restatement of settled law.

VI. Conclusion

The Supreme Court’s judgment in Amlesh Kumar v. State of Bihar firmly reaffirms that fundamental rights under Articles 20(3) and 21 are inviolable at every stage of the criminal process, and that neither courts nor investigating agencies can circumvent these protections, directly or indirectly, in the name of investigative necessity. By confining bail jurisdiction to its limited scope, mandating corroboration for narco-analysis results, and recognizing indirect judicial endorsement as constitutionally impermissible, the Court has meaningfully advanced the cause of individual liberty while simultaneously setting a higher standard of judicial accountability in criminal proceedings. This judgment is not merely a reiteration of settled law but a necessary and significant constitutional reaffirmation that the pursuit of truth must always remain subordinate to the foundational values of human dignity and fair trial.
