Pappu Singh vs. The State NCT of Delhi
Background
The father of a young woman who went missing in 2017 and was later found dead (an FIR for kidnapping and murder was registered against two named suspects) asked the trial court to order a Narco Analysis Test on the accused persons, frustrated by what he saw as slow progress in the investigation, given the case had dragged on for years without a charge-sheet. Both the trial court and, on revision, the Sessions Court rejected his request, since the accused had refused to consent to the test.
Decision Breakdown
The High Court upheld the rejection, applying binding Supreme Court law (Selvi v. State of Karnataka, and the more recent Amlesh Kumar v. State of Bihar) that narco-analysis, polygraph, and similar tests cannot be forced on an unwilling person, doing so would violate their constitutional right against self-incrimination and personal liberty. Crucially, the Court held that even an accused person applying for such a test on themselves has no absolute right to compel it, so a complainant certainly cannot force an unwilling accused to undergo it. While sympathetic to the father's anguish and his right to a fair investigation, the Court noted this application should ideally have come from the investigating officer, not the complainant, and gave him liberty to seek court monitoring of the stalled investigation instead.
Lesson Learnt
No one, not even a grieving family member seeking the truth, can force a suspect to undergo a narco-analysis or lie-detector test without that person's free consent; the right against self-incrimination is treated as absolute and non-negotiable, even in serious cases.
