Case Comment: Kattavellai @ Devakar V. State of Tamil Nadu, Criminal Appeal No. 1672 of 2019 (2025 Insc 845)

The Indian criminal justice system rests on two foundational maxims: fiat justitia ruat caelum—let justice be done though the heavens fall—and audi alteram partem—no person shall be condemned unheard. Nowhere are these principles more rigorously tested than in criminal trials that result in capital punishment. The present case, Kattavellai @ Devakar v. State of Tamil Nadu, raises important questions about the evidentiary threshold for conviction in a capital case that is wholly based on circumstantial evidence. The factual matrix in the case is not just disturbing in its brutality but also in the way the criminal investigation and subsequent prosecution unfolded. Two young individuals were brutally murdered in a remote forest area, with the female victim allegedly subjected to sexual assault. The prosecution's narrative, primarily based on circumstantial evidence and a single key witness (PW-5), culminated in the imposition of the death penalty, which was later confirmed by the Madras High Court and challenged before the Supreme Court. The case is emblematic of the dangers inherent in capital punishment jurisprudence—especially when convictions are grounded in flawed investigations, dubious witness testimonies, and procedural irregularities. It revives the long-standing doctrinal and moral debates around the death penalty in India, particularly in light of the "rarest of rare" doctrine as enunciated in Bachan Singh v.
