## UPSC CSE Context **Why in News:** Supreme Court's 2026 judgment in CP vs AP balances DNA paternity tests with privacy rights. **Syllabus Connection:** Polity: Fundamental Rights (Article 21), Judicial Precedents, Evidence Law. **Exam Relevance:** Tests understanding of right to privacy vs. scientific evidence, proportionality, and judicial evolution. ## Core Issue Balancing DNA paternity tests with right to privacy under Article 21. **Key Development:** SC in CP vs AP (2026) upheld DNA test as last resort when paternity is directly in issue and no other evidence exists. **Stakeholders:** - Children (legitimacy) - Alleged father (privacy) - Mother - Courts (trial courts) ## Static Knowledge **High-Value Background:** - Bharatiya Sakshya Adhiniyam 2023 places burden of proof on party denying paternity. **Exam Linkage:** - Useful for questions on conflict between fundamental rights and scientific evidence. **Concepts in Context:** - Proportionality: test must be necessary and proportionate to the aim. - Legal fiction: presumption of legitimacy vs. scientific proof. ## Dynamic Analysis ### Constitutional/Legal - Post-Puttaswamy, DNA tests must satisfy legality, legitimate aim, and proportionality. - Courts now require no alternative evidence before ordering DNA test. - Adverse inference can be drawn if party refuses test without valid reason. - Tension between scientific infallibility and fundamental rights. ### Society - DNA tests can remove stigma of illegitimacy for children. - Compelled testing may violate bodily autonomy and privacy. - Balancing individual rights with societal interest in truth. ## Prelims Takeaways - K.S. Puttaswamy case (2017) declared right to privacy a fundamental right under Article 21. - Bharatiya Sakshya Adhiniyam 2023 replaced Indian Evidence Act 1872. ## Mains Value Addition **Arguments:** - DNA evidence is reliable but must be balanced with privacy rights. - Proportionality ensures test is last resort, not routine. - Legal fiction of legitimacy protects children but may conflict with truth. **Examples:** - Rohit Shekhar vs N.D. Tiwari: DNA test ordered despite privacy claim. **Data Points:** - Goutam Kundu (1993): first SC case on DNA evidence in paternity. - CP vs AP (2026): latest judgment consolidating principles. **Counterpoints:** - Privacy absolutism may hinder justice in paternity disputes. - Adverse inference may pressure parties to submit to tests. ## Way Forward - Legislate clear guidelines for DNA testing in family disputes. - Ensure informed consent and protect genetic data from misuse. - Strengthen trial courts' capacity to apply proportionality test.
