Introduction
Lily Thomas v. Union of India concerned the legal consequences of a Hindu husband converting to Islam during the subsistence of his first Hindu marriage and then attempting to contract a second marriage. The central question was whether conversion to Islam, by itself, dissolved the first marriage or permitted the husband to escape the monogamy requirement under Hindu matrimonial law.

Subject Matter
Conversion to Islam, validity of second marriage, Hindu marriage, bigamy and personal law.
Facts of the Case
The case arose out of concerns regarding Hindu husbands converting to Islam and thereafter contracting a second marriage while their first Hindu marriage was still subsisting.
One of the important matters involved Sushmita Ghosh, who had married G.C. Ghosh according to Hindu rites on 10 May 1984. During the subsistence of their marriage, her husband decided to convert to Islam and expressed his intention to marry another woman.
The wife approached the Supreme Court questioning whether her husband could avoid the legal consequences of the first marriage simply by converting to another religion.
The controversy was closely connected with the earlier decision in Sarla Mudgal v. Union of India, where the Supreme Court had considered whether a Hindu husband could convert to Islam and then contract a second marriage without dissolving the first marriage.
The proceedings in Lily Thomas were therefore concerned with the legal effect of conversion upon an existing Hindu marriage and the extent to which conversion could be used to contract another marriage.
Issues Before the Court
- Whether conversion of a Hindu husband to Islam automatically dissolves his existing Hindu marriage.
- Whether a Hindu husband can contract a second marriage after conversion to Islam while the first marriage is still subsisting.
- Whether such a second marriage is void under the Hindu Marriage Act, 1955.
- Whether the husband can be prosecuted for bigamy under Section 494 of the Indian Penal Code.
- Whether freedom of religion permits conversion to be used to escape obligations arising from an existing marriage.
Arguments of the Parties
Petitioners
The petitioners argued that conversion could not automatically terminate an existing Hindu marriage. The first marriage continued to create legal obligations until it was dissolved in accordance with law.
They contended that a husband could not convert to Islam merely to contract a second marriage and thereby defeat the rights of the first wife.
Respondents
The dispute involved the relationship between religious conversion, Muslim personal law and the statutory restrictions governing an existing Hindu marriage.
The Court therefore had to determine whether conversion changed the legal status of the first marriage or gave the husband a right to enter into another marriage under Muslim personal law.
Judgment of the Court
The Supreme Court rejected the proposition that conversion to Islam automatically dissolves a Hindu marriage solemnised under the Hindu Marriage Act.
Section 13(1)(ii) of the Hindu Marriage Act recognises conversion as a ground on which the other spouse may seek divorce. However, conversion itself is not an automatic dissolution of the marriage.
The existing marriage therefore continues unless it is dissolved in accordance with law.
The Court further held that a Hindu husband cannot escape the operation of the Hindu Marriage Act merely by changing his religion and claiming the right to contract another marriage under Muslim personal law.
Section 17 of the Hindu Marriage Act makes a subsequent marriage void when it is contracted during the subsistence of a valid earlier marriage in circumstances prohibited by Section 5(i).
Consequently, conversion does not remove the legal consequences of the first marriage.
The Court also held that the second marriage could attract Section 494 of the Indian Penal Code because the first marriage continued to subsist. A husband cannot avoid the criminal law relating to bigamy merely by converting to another religion.
Conversion Does Not Automatically Dissolve a Hindu Marriage
This is the central principle of the case.
A Hindu marriage governed by the Hindu Marriage Act does not come to an end merely because one spouse changes religion.
Conversion is recognised as a ground for divorce under Section 13(1)(ii), but it does not itself dissolve the marriage.
Therefore, a spouse who converts must still comply with the legal requirements governing the existing marriage.
Second Marriage After Conversion
The Supreme Court rejected the argument that conversion to Islam gives a Hindu husband an automatic right to contract a second marriage.
The first marriage remains legally relevant until it is dissolved. The husband cannot rely on the rules of another personal law to erase obligations arising from the earlier marriage.
Therefore, if the first marriage continues to subsist, the subsequent marriage can be treated as void and may also constitute bigamy.
Section 17 of the Hindu Marriage Act
Section 17 of the Hindu Marriage Act is central to the decision.
It provides that a marriage between two Hindus is void if, at the date of the marriage, either party has a husband or wife living and the conditions specified in Section 5(i) are violated.
The significance of the decision is that conversion does not allow a person to avoid this statutory restriction while the earlier marriage remains legally subsisting.
Section 494 of the Indian Penal Code
Section 494 IPC deals with marrying again during the lifetime of a husband or wife.
Where the first marriage remains valid and subsisting, a subsequent marriage may attract the offence of bigamy.
The Court therefore refused to permit conversion to operate as a defence against the consequences of contracting a second marriage during the subsistence of the first.
Freedom of Religion and Matrimonial Obligations
The judgment also makes an important distinction between the right to change one’s religion and the legal consequences of that change.
The Court did not prevent a person from changing religion. The issue was whether conversion could be used to defeat an existing matrimonial obligation.
Freedom of religion does not mean freedom to disregard statutory obligations arising from an existing marriage.
A person may change religion, but that change does not automatically erase the legal consequences of a marriage already solemnised under the Hindu Marriage Act.
Legal Principles Established
1. Conversion does not automatically dissolve a Hindu marriage
A Hindu marriage continues after conversion of one spouse unless it is legally dissolved.
2. Conversion cannot be used to contract a second marriage
A Hindu husband cannot convert to Islam merely to acquire a right to contract a second marriage while his first marriage is subsisting.
3. The second marriage can be void
Where the first marriage continues, the subsequent marriage is void under the applicable provisions of the Hindu Marriage Act.
4. Bigamy liability can arise
A second marriage during the subsistence of the first marriage can attract Section 494 IPC where its requirements are fulfilled.
5. Personal law cannot be selectively used to defeat existing obligations
Conversion does not retrospectively erase matrimonial rights and obligations created under the law governing the first marriage.
Ratio Decidendi
The ratio decidendi of Lily Thomas v. Union of India is that conversion of a Hindu spouse to Islam does not by itself dissolve a marriage solemnised under the Hindu Marriage Act, 1955. Consequently, the converted husband cannot contract a second marriage during the subsistence of the first marriage merely by relying on Muslim personal law. The subsequent marriage is void and can attract the law relating to bigamy.
Why This Case Is Important
The decision is important in family law because it prevents religious conversion from being used as a device to defeat the monogamy requirement imposed by Hindu matrimonial law.
For law students, the case is particularly useful for understanding the relationship between conversion, divorce, validity of marriage and bigamy.
It also illustrates how statutory matrimonial obligations continue to operate even when the personal circumstances of one spouse change.
The case should be read along with Sarla Mudgal v. Union of India because both decisions deal with conversion to Islam and the attempt to contract a second marriage while an earlier Hindu marriage remains subsisting.
Practical Application
Suppose a Hindu man is validly married under the Hindu Marriage Act and later converts to Islam. The conversion does not itself terminate his first marriage.
Unless the marriage has been legally dissolved, he cannot treat himself as unmarried and contract another marriage without facing the legal consequences attached to the subsisting first marriage.
The relevant question is therefore not merely what religion the husband follows at the time of the second marriage, but whether the earlier marriage has been legally dissolved.
Law Student and Judiciary Relevance
For examinations, the basic sequence to remember is:
Hindu marriage → conversion to Islam → no automatic dissolution → first marriage continues → second marriage during subsistence of first marriage → second marriage void → possible bigamy liability.
The case is especially relevant to Sections 5, 11, 13 and 17 of the Hindu Marriage Act and Section 494 IPC.

Conclusion
Lily Thomas v. Union of India establishes that conversion to Islam does not provide an automatic escape from an existing Hindu marriage. The first marriage continues until it is dissolved according to law.
A person cannot convert to another religion and then use that conversion as a legal device to contract a second marriage while the first marriage is still subsisting. The decision therefore protects the legal status of the existing marriage and prevents the misuse of religious conversion to circumvent matrimonial law.
