Context: The Supreme Court has set aside the Patna High Court order permitting an involuntary narco-analysis test, reaffirming that forced narco tests violate Article 20(3).
About Supreme Court’s Ruling on Narco Tests:
What is a Narco Test?
- A narco test involves injecting sedatives like Sodium Pentothal to reduce inhibitions so an accused may reveal concealed information.
It is considered a non-violent investigative tool, similar to polygraph or brain-mapping tests.
Key Judgments and Constitutional Basis:
- Selvi v. State of Karnataka (2010): The Court held that narco, polygraph and brain mapping cannot be administered without voluntary consent.
- Amlesh Kumar v. State of Bihar (2025): Patna HC allowed an involuntary narco test, which SC has now struck down as unconstitutional.
- Article 20(3): Protects against self-incrimination; forced narco tests violate this right.
- Article 21 – Right to Life & Privacy: Forced narco-analysis violates bodily integrity, privacy and personal liberty.
- The Court reiterated the Golden Triangle principle (Articles 14, 19, 21) from Maneka Gandhi (1978) — any investigative procedure must be fair, reasonable, and just.
Features of the SC Ruling:
- Consent must be voluntary, informed, and recorded before a magistrate.
- Medical and legal safeguards mandatory before administering any such test.
- Test results are not proof of guilt — they require independent corroboration (Manoj Kumar Saini 2023, Vinobhai 2025).
- Accused may volunteer for narco-testing under Section 253 of BNSS, but courts need not allow it as a matter of right.
