The case of Deena @ Deena Dayal Etc. v. Union of India and Others is a landmark judgment delivered by the Supreme Court of India on September 23, 1983. The core issue was the constitutional validity of the method of execution prescribed for the death sentence. The petitioners, who were sentenced to death for murder, challenged Section 354(5) of the Code of Criminal Procedure (Cr.P.C.), which mandates that the sentence shall direct the convict "be hanged by the neck till he is dead". They argued that hanging was a cruel, inhuman, and degrading method, thus violating Article 21 of the Constitution, which guarantees the right to life and personal liberty.
The Supreme Court, led by Chief Justice Y.V. Chandrachud, dismissed the petitions. The ratio decidendi of the judgment is that the method of execution by hanging prescribed under Section 354(5) Cr.P.C. does not violate Article 21 of the Constitution. The Court held that the method, when properly administered using the "long-drop" technique, is a quick, simple, and decent procedure that causes the least pain and avoids unnecessary barbarity, torture, or degradation. The judgment was based on an examination of medical evidence, expert testimonies, and a comparative analysis of other methods like electrocution and lethal injection, concluding that none offered a distinct advantage over hanging.
This judgment connects directly to the jurisprudence on capital punishment, particularly the "rarest of rare" doctrine established in Bachan Singh v. State of Punjab (1980), which upheld the constitutional validity of the death penalty itself. The Deena precedent was subsequently considered and approved by a Constitution Bench in Shashi Nayar v. Union of India (1992). The method of execution has not changed recently; the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, which replaced the Cr.P.C., retains hanging as the prescribed method under Section 393(5). The Supreme Court recently reaffirmed the binding nature of the Deena judgment in August 2026, dismissing a challenge to hanging.
