Facts of the Case

  • The case arose from a dowry death allegation, where the husband (appellant) and his family were accused.

  • While other family members got bail, the husband’s bail was denied by the Patna High Court.

  • The High Court accepted the police’s submission that a narco-analysis test would be conducted on all accused during investigation.

  • The appellant challenged this before the Supreme Court, citing the ruling in Selvi v. State of Karnataka (2010) which declared forcible narco-analysis unconstitutional.

  • The Supreme Court appointed amicus curiae Gaurav Agarwal to assist in addressing constitutional concerns.

Issues

  1. Whether the High Court was correct in accepting the conduct of narco-analysis during bail proceedings..

  2. Whether voluntary narco-analysis can be requested by an accused and if such test reports can form sole basis of conviction.

  3. Whether the accused has an indefeasible right to undergo narco-analysis during the trial.

Judgement

  • The Supreme Court overruled the High Court, holding that accepting narco-analysis at the bail stage was procedurally and constitutionally improper.

  • Involuntary narco-analysis is prohibited under Articles 20(3) and 21.

  • Voluntary narco-analysis is permitted only at the appropriate trial stage and with safeguards, but it is not a fundamental or indefeasible right.

  • Information discovered through such tests can be admissible under Section 27 of the Indian Evidence Act, but cannot be sole basis for conviction.

Held

  • High Court erred by considering narco-analysis at the bail stage—a bail hearing is not the forum to suggest or order such investigative procedures.

  • No one can be forced to undergo a narco-analysis test; consent is mandatory, and even then, it must be judicially scrutinized.

  • Accused can request voluntary narco-analysis, but the court must evaluate:

    • Free and informed consent

    • Need and timing

    • Adequate procedural safeguards

  • Such tests alone cannot determine guilt; they must be supported by independent and corroborative evidence.

Analysis

  • The Reaffirmed the Selvi (2010) precedent, protecting individuals against self-incrimination and unlawful bodily intrusion.

  • It Clarified that bail hearings must focus on standard criteria like nature of the offence, custody period, evidence prima facie, and not delve into complex investigative measures.

  • The Court disapproved of High Courts bypassing trial safeguards by ordering narco-tests as bail conditions or investigation methods.

  • Highlighted the unreliability of narco-analysis, reinforcing that its evidentiary value is limited.

  • Distinguished between investigative usefulness and admissibility in court, ensuring accused rights remain protected during the trial.
