Facts of the Case
-
The dispute arose over the paternity of a child born in 2007 during a valid marriage.
-
The respondent alleged an extramarital relationship with the appellant (a doctor) and claimed he was the biological father.
-
FIRs were registered under Sections 417 and 420 IPC and the Tamil Nadu Women Harassment Act.
-
During investigation, the police sought DNA testing of the appellant, respondent, and the child.
-
The Madras High Court ordered the DNA test, which was affirmed by a Division Bench, prompting the Supreme Court appeal.
Issues
-
Whether a DNA test can be directed routinely to determine paternity?
-
Whether the presumption of legitimacy under Section 112 can be rebutted without strong evidence?
-
Whether compulsory DNA testing violates fundamental rights under Article 21?
-
Whether Sections 53 and 53A CrPC authorize DNA testing in such circumstances?
-
Whether an adverse inference can be drawn from refusal to undergo a DNA test without a lawful order?
Judgement
-
he Supreme Court set aside the Madras High Court order directing DNA testing.
-
DNA tests cannot be used as a tool for speculative “fishing inquiries.”
-
The presumption of legitimacy under Section 112 operates as conclusive proof, and can only be rebutted by strong, unambiguous evidence proving non-access between spouses.
-
Compelling DNA testing is a serious intrusion on privacy and personal liberty, and must satisfy the tests of legality, legitimate state aim, and proportionality.
-
There must be a direct and demonstrable nexus between the DNA test and the alleged offense; no such nexus existed in this case.
-
An adverse inference cannot be drawn unless a lawful order for DNA testing has been issued.
Held
-
DNA tests cannot be ordered routinely in paternity disputes.
-
The child’s legitimacy remains protected under Section 112.
-
The High Court’s direction for DNA testing was quashed.
-
Appeal allowed in favor of the appellant.
Analysis
-
The Court reaffirmed the primacy of Section 112 in protecting the legitimacy of children born during marriage, preventing casual or unsubstantiated claims from illegitimizing a child.
-
DNA testing is recognized as a powerful scientific tool but must only be used when absolutely necessary, proportional, and relevant to the case.
-
Article 21 was invoked to emphasize that privacy rights of individuals including the child and the alleged father cannot be overridden by speculative investigation.
-
Consent of one party does not waive the privacy rights of others involved.
-
The judgment prevents misuse of DNA profiling in criminal investigations for collateral issues unrelated to the offense.
-
Establishes a two-fold safeguard: (i) necessity for the test, (ii) balance of interests between parties.
-
Courts must exercise circumspection in ordering scientific tests that may affect the dignity, social legitimacy, or legal rights of individuals.
