The Madras High Court has clarified that a DNA test cannot be ordered simply because the paternity of a child has been questioned during a criminal case alleging bigamy.
Madras High Court: DNA Test Cannot Be Ordered Merely to Establish Bigamy When Paternity Is Only a Side Issue
Justice Mohammed Shaffiq observed that where the allegation concerns a person allegedly marrying again while an earlier marriage was still legally subsisting, the biological paternity of a child does not directly establish the offence. Therefore, a compulsory DNA examination cannot be justified merely to investigate an issue that is only incidental to the main allegation.
How the dispute arose
The case originated from a matrimonial relationship in which a man married the complainant in January 2011. A male child was born to them in June 2012.
The woman later alleged that the man had concealed the fact that he was already married. She consequently initiated criminal proceedings alleging, among other offences, concealment of a previous marriage and cheating.
During the trial, the man disputed that he was the biological father of the child. Questions were also raised concerning the woman’s previous marital relationship.
Following these developments during cross-examination, the prosecution sought DNA testing of the man, the woman and the minor child. The trial court permitted the examination.
The man challenged that order before the Madras High Court, arguing that the DNA test had no direct connection with the offences being tried.

High Court examines whether DNA testing was necessary
The High Court focused on a basic question: Would the result of the DNA test directly help establish the ingredients of the alleged offence?
The Court answered in the negative.
Justice Mohammed Shaffiq noted that proceedings under Sections 494 and 495 of the IPC concern the existence of a second marriage while an earlier marriage remains in force, with Section 495 additionally dealing with concealment of the earlier marriage.
The Court therefore held that determining whether the accused was the biological father of the child would not prove that he had entered into a legally recognised second marriage.
In other words, even if a DNA examination established a biological relationship, that result by itself could not establish the solemnisation of the alleged second marriage.
DNA testing requires more than a disputed allegation
The High Court stressed that DNA testing is not something courts should order routinely whenever paternity is questioned.
According to the Court, there must be an “eminent need” for such an intrusive examination, and the fact sought to be established through DNA evidence should have a direct connection with the dispute before the court.
In the present matter, paternity was treated as a collateral question rather than an essential element of the alleged bigamy offence.
The Court consequently found that the trial court had proceeded on an incorrect understanding of the legal relevance of the proposed DNA examination.
What must actually be proved in a bigamy case?
The ruling reinforces an important distinction in criminal proceedings involving alleged bigamy.
The prosecution must establish the legally relevant elements of the alleged second marriage. Evidence concerning the marriage itself, including the circumstances and legally required ceremonies where applicable, is therefore central to such a case.
The birth of a child or proof of biological paternity does not automatically establish that a valid second marriage took place.
This principle had also been recognised in an earlier Madras High Court decision, where the Court observed that a DNA test could not establish the fact of a second marriage because biological parentage and solemnisation of marriage are two different questions.
Court protects against unnecessary DNA examinations
The judgment also highlights the need for caution before compelling an individual to undergo DNA testing.
Such examinations can involve significant questions concerning bodily autonomy, privacy and personal dignity. Consequently, courts have increasingly emphasised that DNA analysis should not become a routine investigative tool when the information sought can be established through other legally acceptable evidence.
The key principle emerging from the ruling is that DNA evidence must have a meaningful and direct connection with the issue that the court is required to decide.
What the judgment means
The Madras High Court’s decision makes it clear that questioning a child’s paternity during a bigamy proceeding does not automatically open the door to compulsory DNA testing.
Where paternity is merely a collateral issue and does not help establish the alleged second marriage or concealment of an existing marriage, ordering a DNA test would serve little legal purpose.
The judgment therefore places the emphasis back on the actual ingredients of the alleged offence rather than allowing a collateral dispute over parentage to become the centre of the criminal proceedings.
Key takeaway
A DNA test cannot be used as a shortcut to prove bigamy when the child’s paternity has no direct bearing on whether the accused contracted a second marriage. Courts must first determine whether there is a compelling legal necessity for such an intrusive examination and whether its result is directly relevant to the offence under consideration.
