Nikhat Parveen v. Rafique: DNA proof overrides the presumption of legitimacy (2026)

The facts in brief

The proceeding began as a maintenance claim. The wife, on behalf of herself and the child, sought maintenance from the respondent husband. The legal architecture in such a claim is ordinarily straightforward: a child born during a subsisting valid marriage is presumed legitimate, and the husband is the presumed father with the corresponding obligation to maintain.

What displaced that ordinary architecture was a single piece of evidence. A DNA test had been conducted — crucially, with the mother's consent — and the report was already on the record. That report conclusively established that the respondent was not the biological father of the child. The test had attained finality; it was not a contested or freshly demanded examination, but a completed, consented, undisputed report already part of the record before the Court.

On that footing the question for the Supreme Court was narrow but consequential: does the statutory presumption of legitimacy, expressed in the language of conclusive proof, survive a reliable scientific finding to the contrary, or must it give way?

The questions

The appeal placed two related questions before the Court.

First, the doctrinal question: where a statute declares a fact to be conclusive proof — language that ordinarily forecloses any contrary evidence — can that statutory conclusiveness be displaced by a scientific report that proves the opposite? The presumption of legitimacy under Section 112 of the Indian Evidence Act, carried forward into Section 116 of the Bharatiya Sakshya Adhiniyam, is not a mere rebuttable presumption; it is framed as conclusive, defeasible historically only by proof of non-access between the spouses. DNA evidence, unavailable when the provision was conceived, sits uneasily against that older, access-based scheme.

Second, the consequential question: if the presumption yields, what follows for maintenance? A maintenance obligation toward a child under Section 125 of the Code of Criminal Procedure — and the corresponding provision of the Bharatiya Nagarik Suraksha Sanhita — rests on the relationship of parent and child. If paternity is scientifically negated, the foundation of the maintenance claim qua that child is removed.

What the Court held

The Court held that the conclusive presumption of legitimacy must yield to a reliable DNA test report that is already on record, was conducted with consent, and has attained finality.

That sentence is the ratio. The presumption in Section 112 / Section 116 is a legal device for ascertaining a fact — paternity — in the absence of better proof. Where better proof exists, in the form of an accurate, consented, undisputed DNA report, the device has nothing left to do. The law's conclusive proof was always a proxy for the truth it presumed; once the truth is established by science, the proxy cannot stand against it.

The consequence for the maintenance claim followed directly. A man conclusively shown by DNA not to be the biological father cannot be directed to pay maintenance for that child, notwithstanding the child's birth during the marriage. The maintenance claim qua that child was therefore held unsustainable.

The Court was careful, however, to fence the holding. It reaffirmed that courts should ordinarily exercise extreme caution before ordering a DNA test, precisely because such an order risks stigmatising a child and intruding on the dignity and privacy interests that the presumption of legitimacy was designed to protect. The rule the Court laid down shifts the position only where an accurate, consented, undisputed test already exists on the record. It does not license a husband to demand a paternity test as a routine answer to a maintenance claim, nor does it dilute the strong protection the presumption affords in the ordinary case.

Analysis

The judgment sits at the intersection of two doctrines that have been on a collision course for years: the conclusive presumption of legitimacy, an instrument of nineteenth-century evidence law, and forensic DNA profiling, a twentieth-century certainty. Section 112 was drafted for a world in which paternity could be inferred only from access and opportunity. Its conclusiveness was protective — it shielded children from the social and legal consequences of bastardy and discouraged invasive inquiries into the marital relationship. The defeasance route it contemplated, proof of non-access, was deliberately demanding.

The Court's resolution is notable for what it does not do. It does not declare the presumption obsolete, nor does it convert it into a freely rebuttable one. Instead it draws a precise line between ordering a test and relying on a test already taken. That distinction does the protective work the presumption was meant to do. By retaining the strong rule against compelling DNA testing — a position consistent with the Court's longstanding insistence on caution before disturbing legitimacy — the Bench preserves the child-protective core of Section 112. By recognising that a consented, final, undisputed report cannot be ignored, it prevents the presumption from being weaponised against the truth in the rare case where the truth is already known.

The framing in terms of conclusive proof versus scientific advancement is doctrinally significant. Conclusive proof, in the Evidence Act scheme, is the strongest evidentiary category the statute knows: once a fact is declared conclusively proved, the court must regard it as established and shall not allow evidence to disprove it. For the Court to hold that even this category yields to a reliable DNA finding is to recognise that statutory conclusiveness is ultimately instrumental, not absolute — a means of finding facts that cannot survive a more accurate means of finding the same fact.

The re-enactment dimension matters too. Section 112 of the Indian Evidence Act is repealed; Section 116 of the Bharatiya Sakshya Adhiniyam carries the same conclusive presumption forward in substance. By deciding the question on both provisions, the Court ensures that its holding is not orphaned by the statutory transition. The jurisprudence built around legitimacy and paternity continues seamlessly into the new evidence code, and the ratio governs cases arising under either enactment.

Why it matters

For maintenance practice the decision supplies a clean answer to a recurring fact pattern: a man resisting a maintenance claim on the ground that he is not the child's father, with a completed DNA report on the record. Before this ruling, the conclusive language of the presumption left room for argument that the report was simply irrelevant against a fact the statute deemed conclusively proved. After it, where the report is reliable, consented and final, that report governs and the maintenance claim qua that child fails.

Equally important is what the decision protects. By keeping the bar against ordering DNA tests high, it ensures that the ruling cannot be turned into a tactical device. A husband cannot answer a maintenance petition by routinely demanding a paternity test and putting the child's legitimacy in issue; the presumption continues to do its protective work in the ordinary case. The narrow gateway — an accurate, consented, undisputed test already on record — confines the holding to the situation where the truth has already been established without coercion.

The judgment also models the interpretive posture the new codes invite. Where a provision is re-enacted in substance — here, Section 112 of the Evidence Act into Section 116 of the Bharatiya Sakshya Adhiniyam — the settled understanding travels with it, and courts need not relitigate the question merely because the section number has changed. For practitioners, the practical takeaway is precise: the presumption of legitimacy remains a strong shield, but it is a shield against uncertainty, not against a reliable, consented scientific certainty already before the court.
