1. Legal Basis of Nullity in Mixed Marriages

A marriage may be declared void or voidable if:

(A) Void marriages (Section 11, HMA)

A marriage is void if:

• One party already has a living spouse (bigamy)
• Parties are within prohibited degrees of relationship
• One party is not a Hindu when HMA applies (jurisdictional defect)

(B) Voidable marriages (Section 12, HMA)

Marriage may be annulled if:

• Consent obtained by fraud or force
• Impotency
• Mental incapacity
• Misrepresentation of identity or religion (in extreme cases)

(C) Interfaith validity rule

• Under HMA: both parties must be Hindus
• Otherwise marriage is void unless solemnised under SMA

2. Key Principle in Mixed Marriage Nullity Claims

Courts focus on:

(i) Whether the statute applies at all

If parties are not Hindus → HMA cannot validate marriage.

(ii) Whether consent was vitiated

If one spouse misrepresented religion/identity → annulment possible.

(iii) Whether proper law (SMA) was used

If interfaith marriage not under SMA → legal invalidity likely.

3. Important Case Laws (At least 6)

1. Gullipilli Sowria Raj v. Bandaru Pavani (2008)

The Supreme Court held that a marriage between a Hindu and a Christian solemnised under HMA is void, because HMA applies only when both parties are Hindus. The court ruled that such a marriage has no legal validity under HMA.

Principle:
👉 Interfaith marriage under HMA = nullity (void ab initio)

2. Naurang Singh v. Sapla Devi (Allahabad HC, 1968)

The court held that a second marriage during the subsistence of a first marriage is void under Sections 5 and 11 HMA and cannot be legally recognized.

Principle:
👉 Bigamous marriage = automatic nullity

3. Mohd. Ikram Hussain v. State of U.P. (1964 Cri LJ 590)

The court observed that a second marriage while the first spouse is alive is null and void under HMA.

Principle:
👉 Existing marriage bars validity of second marriage

4. Ishwar Singh v. Smt. Hukam Kaur (AIR 1965 All 464)

Held that a Hindu cannot contract a valid second marriage without dissolution of the first.

Principle:
👉 Prior subsisting marriage destroys validity of second marriage

5. Sarla Mudgal v. Union of India (1995) 3 SCC 635

The Supreme Court ruled that conversion to another religion solely to contract a second marriage is invalid in law, and such second marriage is void.

Principle:
👉 Conversion cannot defeat monogamy law; second marriage remains void

6. Lily Thomas v. Union of India (2000) 6 SCC 224

Reaffirmed Sarla Mudgal and held that conversion does not automatically dissolve marriage, and bigamy remains punishable.

Principle:
👉 Conversion ≠ automatic dissolution → second marriage void

7. Lata Singh v. State of U.P. (2006) 5 SCC 475

While protecting interfaith marriages, the court clarified that couples must use Special Marriage Act for legal recognition.

Principle:
👉 Interfaith marriage is valid only under SMA protection

8. S. Nagalingam v. Sivagami (2001) 7 SCC 487

Held that a marriage performed without essential legal requirements is void and cannot be treated as valid.

Principle:
👉 Non-compliance with statutory conditions = nullity

4. Typical Grounds for Nullity in Mixed Marriage Cases

(A) Lack of legal capacity under personal law

Example: Hindu–Christian marriage under HMA → void

(B) Fraudulent representation of religion

If one spouse pretends to be Hindu/Muslim → annulment under Section 12 HMA

(C) Absence of statutory framework

If neither HMA nor SMA requirements are met → marriage legally non-existent

(D) Bigamy in disguise

Second marriage during subsisting first marriage → void under Section 11

(E) Non-recognition under personal law

Some personal laws do not recognise interfaith unions without conversion or proper form

5. Legal Effects of Nullity Declaration

If a marriage is declared void:

• No spousal rights (maintenance may be limited)
• Property rights may still arise in some cases
• Children are protected under Section 16 HMA (legitimate children of void marriages)
• No divorce required because marriage is treated as never existing

6. Important Legal Distinction

Conclusion

Mixed marriage nullity claims in India mainly revolve around jurisdictional defects, interfaith incompatibility under personal law, fraud in consent, and bigamy issues. Courts consistently hold that:

• Interfaith marriages under HMA are void (Gullipilli Sowria Raj)
• Conversion cannot defeat existing marriage (Sarla Mudgal, Lily Thomas)
• Proper route for interfaith unions is Special Marriage Act
