Supreme Court’s Evolving Stance on Compulsory DNA Paternity Tests and Privacy Rights (1993‑2026)
The Indian judiciary has gradually shaped the law on DNA‑based paternity testing. Early cases limited routine testing, while later judgments balanced the right to privacy with the need for scientific proof when legitimacy was in dispute. This trajectory reflects how constitutional rights, statutory provisions, and forensic science intersect in Indian law.
Key Developments (chronological)
- 1993 – Goutam Kundu: Court held DNA tests cannot be ordered routinely; a strong prima‑facie case must first be shown.
- 2005 – Shri Banarsi Dass: Re‑affirmed protection of legitimacy over forensic curiosity.
- 2014 – Nandlal Wasudeo Badwaik: Accepted that reliable scientific proof can override legal fiction if it serves justice.
- 2014 – Dipanwita Roy: Noted that refusal to test may lead to adverse inference.
- 2017 – K.S. Puttaswamy (2017): Introduced the three‑fold test of legality, legitimate aim and proportionality for any privacy‑intrusive measure.
- 2023 – Aparna Ajinkya Firodia: Applied the Puttaswamy test, allowing DNA tests only when necessary and proportionate.
- 2025 – Ivan Rathinam: Stated that privacy and knowledge are not absolute; courts must weigh stigma against necessity.
- 2026 – CP vs AP: Upheld a trial court order for DNA testing, citing lack of alternative evidence and the need for scientific determination, applying necessity and proportionality.
Important Legal Foundations
The burden of proof in paternity disputes rests on the party denying paternity, as mandated by the Indian Evidence Act 1872 and the Bharatiya Sakshya Adhiniyam 2023. The Supreme Court’s later rulings overlay these statutes with constitutional privacy safeguards.
Exam Relevance
Understanding this jurisprudence is vital for GS 2 (Polity) and GS 5 (Security & Law). It illustrates how the Constitution (Article 21) interacts with statutory law, the role of the judiciary in interpreting rights, and the balance between individual autonomy and societal interests. The evolution also showcases the use of scientific evidence in legal processes, a recurring theme in ethics and governance questions.
Way Forward
- Develop clear procedural guidelines for DNA testing that embed the three‑fold Puttaswamy test.
- Ensure that courts first explore alternative evidence before ordering a test, to respect privacy.
- Legislate safeguards for the storage and use of genetic data, aligning with the right to bodily autonomy.
- Educate legal practitioners and law‑students on the proportionality principle to avoid unnecessary infringement of privacy.
By treating DNA testing as a last resort, the judiciary aims to protect personal dignity while allowing science to serve justice when no other evidence can resolve a paternity dispute.
