Sarla Mudgal v. Union of India (1995): conversion, the second marriage, and bigamy under Section 494

Sarla Mudgal v. Union of India is one of the Supreme Court's most discussed decisions on the boundary between religious conversion and the criminal law of marriage. Decided in May 1995 by a two-judge Bench, the judgment confronted a recurring stratagem: a Hindu man, already married under Hindu law, embraces Islam and promptly takes a second wife, treating his new faith as a passport out of the monogamy rule and out of the reach of the bigamy provision. The Court held that the device does not work. The first marriage survives the conversion, the second marriage is void, and the convert is exposed to prosecution for bigamy. Kuldip Singh, J. delivered the leading judgment; R.M. Sahai, J. wrote a separate concurring opinion.

The facts in brief

The decision arose out of four connected petitions. The lead petitioner, Sarla Mudgal, was the president of "Kalyani," an organisation working with distressed women. The petitions placed before the Court a common, and by then familiar, fact pattern.

In the representative instance, Meena Mathur discovered that her husband, Jitender Mathur, had married Sunita Narula, who had taken the name Fathima. Both husband and the second wife had ostensibly converted to Islam. Meena's case was that the conversion was not a matter of genuine faith at all, but a contrivance — a way of contracting a second marriage while sidestepping the offence of bigamy under Section 494 of the Penal Code. Stripped to its essentials, the situation across the petitions was the same: a Hindu husband, married under the Hindu Marriage Act 1955, converts to Islam and marries again while his first Hindu marriage remains undissolved and subsisting.

The questions

The petitions raised a cluster of closely linked issues. First, whether a Hindu husband married under Hindu law, having converted to Islam, can contract a valid second marriage during the subsistence of his first marriage. Second, whether that second marriage — the first not having been dissolved — is valid or void. Third, whether the convert-husband is guilty of the offence of bigamy under Section 494. And fourth, underlying all of these, what effect conversion has on a subsisting first marriage solemnised under the Hindu Marriage Act.

Each of these turned on a single conceptual point: does a change of religion by one spouse, by itself, bring the first marriage to an end? If it does, the second marriage might be defended as lawful and the bigamy charge would fall away. If it does not, the first marriage continues, the second is contracted "during the life of" an existing spouse, and the bigamy provision is engaged.

What the Court held

The Court rejected the argument that conversion dissolves the first marriage. A marriage solemnised under the Hindu Marriage Act 1955, it held, can be brought to an end only on a ground recognised by that Act and through the machinery the Act provides. Conversion to another faith is not among those grounds and does not operate to dissolve the marriage automatically. The first marriage therefore continues to subsist notwithstanding the husband's embrace of Islam.

From that premise the rest followed. Because the first marriage subsists, a second marriage contracted by the convert-husband is contracted while a spouse is still living and the earlier marriage is still in force. Such a second marriage is void. And the convert-husband is guilty of bigamy under Section 494 of the Penal Code. The Court was clear that conversion to Islam furnishes no defence: a man cannot escape the consequences of the bigamy provision by changing his religion between the first and second marriage. The reasoning connected the criminal provision to the Hindu Marriage Act itself — Section 17 of that Act treats a second marriage during the subsistence of a Hindu marriage as void and attracts the penal consequences of bigamy, while Section 11 renders such a marriage a nullity.

The Court placed this conclusion on a wider footing. Matters of marriage, it reasoned, are of a secular character. They cannot be claimed under the constitutional guarantees of freedom of religion in Articles 25 and 26 so as to defeat the rule against plural marriage that the law imposes. The convert-husband's reliance on his new personal law could not be used as a shield against an obligation the secular law of marriage continued to impose on him.

The Uniform Civil Code observations

It is in this part of the judgment that Sarla Mudgal became a fixture of public debate — and it is also the part most often misdescribed. Kuldip Singh, J., echoing the Court's earlier remarks in Mohd. Ahmed Khan v. Shah Bano Begum, urged the Government to act under Article 44 of the Constitution to secure for citizens a Uniform Civil Code. In his concurring opinion, Sahai, J. added that the need for such a code could not be doubted, while cautioning that its implementation required a favourable social climate.

These remarks must be read for what they are. They are obiter dicta — observations made in passing, recommendatory in character, and not the binding ratio of the decision. The case was decided on the law of conversion, the validity of the second marriage, and the application of Section 494; the call for a Uniform Civil Code was not necessary to that decision. The Supreme Court itself later made the point explicit. In Lily Thomas v. Union of India the Court clarified that the Uniform Civil Code observations in Sarla Mudgal were not a binding direction to the Government and did not amount to a mandamus. Anyone citing Sarla Mudgal in the Article 44 debate should be careful to keep the binding holding on bigamy distinct from the non-binding exhortation about a common civil code.

Analysis

The strength of Sarla Mudgal lies in how directly it answers the device it was confronted with. The argument that conversion ends a marriage has an obvious attraction for a husband who wishes to remarry: if the first marriage simply evaporates on a change of faith, there is no subsisting marriage, no second marriage "during the life of" a spouse, and no bigamy. The Court closed that route by insisting that a statutory marriage is dissolved only as the statute permits. The Hindu Marriage Act created the marriage and prescribed the routes out of it; a unilateral change of religion is not one of them. Conversion may alter the convert's personal status in other respects, but it does not, of its own force, unmake the marriage he is already in.

That reasoning also explains why the Court treated marriage as secular for this purpose. The point was not to deny anyone the freedom to convert — that freedom was not in issue — but to deny that the act of conversion could be deployed to defeat an obligation the law of marriage continued to impose. To allow otherwise would have let the bigamy provision be neutralised at will by a change of religious label, leaving the first wife without the protection the law was meant to give her.

The judgment is best understood as a protective decision about the rights of the first wife as much as a doctrinal statement about conversion. The fact pattern in each petition was a woman left in an undissolved marriage while her husband took a second spouse under cover of a new faith. The holding restores her position: her marriage subsists, the later marriage is void, and the husband's conduct is an offence rather than a lawful exercise of personal-law freedom.

Later trajectory

The core ratio of Sarla Mudgal was affirmed five years later in Lily Thomas v. Union of India. There the Court reiterated that conversion to Islam does not dissolve a Hindu marriage, that a second marriage so contracted is void, and that it is an offence under Section 494 of the Penal Code read with Section 17 of the Hindu Marriage Act. Lily Thomas also addressed an argument that Sarla Mudgal had laid down new law that could not be applied to earlier conduct; the Court held that Sarla Mudgal had not in fact created any new offence but had stated the law as it stood, so no question of retrospective application arose. And, as noted above, it clarified that the Uniform Civil Code observations were not a binding mandate.

Beyond bigamy, Sarla Mudgal has become a recurring anchor in the long-running debate over Article 44 and a Uniform Civil Code, frequently invoked alongside the maintenance and personal-law decisions that frame that discussion. Its doctrinal core, however, is narrower and firmer than the headlines it generates: conversion does not dissolve a subsisting Hindu marriage, and the convert who marries again while it lasts answers for bigamy.

Why it matters

For practitioners in family and criminal law, Sarla Mudgal settles a question that continues to arise: a change of religion does not, by itself, end a marriage solemnised under a statute that prescribes its own grounds of dissolution. A second marriage contracted in the interval is void, and the convert is liable to prosecution under Section 494. The decision should be cited for that proposition. Its observations on a Uniform Civil Code, while influential in public debate, are obiter and were later confirmed to carry no binding force — a distinction that careful citation should always preserve.
