A prosecutes B for Adultery with C, A's wife. B denies that C is A's wife but the court convicts B of Adultery. Afterwards, C is prosecuted for bigamy in marrying B during A's life time. C says that she never was A's wife. Is the judgement against B irrelevant as against C? Also: A files a suit against B for declaration that house X belongs to him and obtains a declaratory decree. Now C files a suit against A for delivery of house X. A pleads in defence that the court has already made a declaration that house X belongs to him. Will the court accept this defence?

Problem I: The Adultery–Bigamy Chain

The Facts and the Question

A prosecutes B for adultery with C, A's wife. B denies that C is A's wife at all. The Court, however, convicts B of adultery — thus implicitly finding, as a necessary step in arriving at that conviction, that C was indeed A's wife. Subsequently, C is prosecuted for bigamy in marrying B during A's lifetime. C now contends that she was never A's wife.

The question is stark: can the earlier conviction of B — which necessarily decided that C was A's wife — be used as a judgment binding upon C in the later bigamy prosecution? Is C shut out from contending that she was never A's wife?

The Answer: The Judgment Is Irrelevant Against C

The answer, stated firmly by Illustration (b) to Section 43 of the IEA — and it is worth noting that this very illustration is omitted in the corresponding Section 37 of the BSA, 2023, though the principle it embodies remains intact — is:

"A prosecutes B for adultery with C, A's wife. B denies that C is A's wife, but the Court convicts B of adultery. Afterwards, C is prosecuted for bigamy in marrying B during A's lifetime. C says that she never was A's wife. The judgment against B is irrelevant as against C."

The reason is as clear as it is fundamental.

Why Is It Irrelevant?

The conviction of B was a judgment delivered in a proceeding to which C was a complete stranger. C was not a party. C had no notice, no right to appear, no opportunity to adduce evidence, no opportunity to cross-examine the witnesses who deposed that she was A's wife, and no right of appeal. As the celebrated Duchess of Kingston's Case (1776 168 ER 175) declared, "it would be unjust to bind any person who could not be admitted to make a defence, or to examine a witness, or to appeal from a judgment he might think erroneous."

The judgment against B is a judgment in personam — it settles the criminal liability of B for his conduct. It is not a judgment in rem that pronounces upon the status of C as a married woman. The four categories of judgment in rem under Section 41 IEA are: probate, matrimonial, admiralty, and insolvency jurisdiction. A criminal conviction for adultery pronounced in a trial between A and B falls into none of these categories.

The fact that the Court in the adultery case incidentally found, as a step in the reasoning, that C was A's wife does not convert that finding into a decree of a Matrimonial Court pronouncing on the status of C's marriage. Only a Matrimonial Court — exercising jurisdiction under the Hindu Marriage Act, the Special Marriage Act, or other applicable personal law statutes — can deliver a judgment in rem on matrimonial status. A criminal court convicting B of adultery is exercising criminal jurisdiction, not matrimonial jurisdiction.

There is a further and equally important reason. The charge in the bigamy prosecution is against C — not against B. C is the person whose liberty is at stake. The entire edifice of criminal procedure rests on the principle that no person may be convicted on the basis of findings made in proceedings where that person had no opportunity to defend themselves. In Jayendra Vishnu Thakur v. State of Maharashtra (2009 7 SCC 1041), the Supreme Court reinforced this as a constitutional imperative rooted in Articles 14 and 21. To allow the finding in the adultery case to bind C in the bigamy case would be to convict C, at least in part, on evidence that was never tested against C.

Can the Judgment Be Used at All?

The answer is nuanced. The conviction of B, as a judgment, is irrelevant as against C under Section 43. However, the evidence recorded in the adultery case may become admissible against C under Section 33 IEA / Section 27 BSA, if the conditions of that section are satisfied — meaning that C was a party, or that the adverse party in the adultery case was a privy to C, and that the question in issue was substantially the same. Since C was not a party to the adultery case and the parties in the two proceedings are entirely different, Section 33 would also likely not be available.

Similarly, the existence of the judgment is not wholly without relevance in the world of evidence. If C had conducted herself in a manner consistent with being A's wife — if, for instance, she had received maintenance as A's wife, or had described herself as A's wife in other documents — those facts could be proved under other sections. But the conviction of B cannot itself be used against C as proof that she was A's wife.

A Comparative Nuance Under BSA, 2023

It is significant, from the perspective of a student of the BSA, 2023, that Section 37 omits Illustration (b) relating to adultery from Section 43 IEA. This is because the offence of adultery has been decriminalised following Joseph Shine v. Union of India (2018 2 SCC 189), in which the Supreme Court struck down Section 497 of the IPC as unconstitutional. The principle itself, however, is preserved and flows directly from the text of Section 37 BSA and its surviving illustrations.

Problem II: The Declaratory Decree and the Stranger Plaintiff

The Facts and the Question

A files a suit against B for a declaration that House X belongs to A and obtains a declaratory decree. Subsequently, C — who was never a party to that suit — files a suit against A for delivery of House X. A pleads in defence that the Court has already declared House X to belong to him by a declaratory decree, and argues that this decree should shut out C's claim.

Will the Court accept this defence?

The Answer: The Court Will Not Accept the Defence

No. The Court will not accept this defence. The declaratory decree obtained by A against B is a judgment in personam. It binds A and B, and those claiming through B — but it does not and cannot bind C, who was a stranger to that litigation.

The Reason: Nature of a Declaratory Decree

Section 34 of the Specific Relief Act, 1963 empowers a Court to make a declaratory decree in favour of a person who asserts a legal character or a right to property against a person who denies or is interested in denying that right. The learned authors of the texts and the Courts have consistently held that a declaratory decree operates only inter partes — it declares the right of A against B and settles the dispute between those two persons. It does not, by any alchemy of law, become a proclamation to the whole world that A owns House X.

Section 35 of the Specific Relief Act itself says: "A declaration made under this Chapter is binding only on the parties to the suit, persons claiming through them respectively, and, where any of the parties are trustees, on the persons for whom, if in existence at the date of the declaration, such parties would be trustees." This language is unmistakable: it is a judgment in personam.

The Act further expressly clarifies — in the notes appended to Section 41 IEA, discussed by the learned authors — that a declaratory decree is specifically treated as a judgment in personam, expressly preserved from being treated as a judgment in rem. Had the legislature intended otherwise, it would have included declaratory decrees in the four categories under Section 41. It did not.

Section 43 IEA / Section 37 BSA is therefore directly applicable. The declaratory decree obtained by A against B is neither a judgment covered by Section 40 (res judicata, which operates only between the same parties), nor by Section 41 (judgment in rem in probate, matrimonial, admiralty or insolvency jurisdiction), nor by Section 42 (judgment on matters of public nature). As a judgment, therefore, it is irrelevant in the suit between A and C.

The Position If A Had a Good Title

Of course, if A truly owns House X, he can prove it in the suit brought by C by other means — by title deed, by adverse possession, or by other documentary or oral evidence. The declaratory decree against B may even be relevant as evidence of a transaction under Section 13 IEA / Section 11 BSA — it could be used to show that A has asserted his title and that the assertion was judicially recognised in a proceeding against B — but it cannot be used as a conclusive bar against C. C is entitled to contest A's title on its merits.

As was authoritatively held in K.G. Premshanker v. Inspector of Police (2002 8 SCC 87), even where a judgment exists on a question between two parties, its effect as against a third party must be assessed strictly by the framework of Sections 40 to 43. A judgment between A and B cannot, by itself, be conclusive against C. The Court in that proceeding would have to decide A's title afresh on the evidence led before it, treating C's claim with the full freedom that C, as a person who never had an opportunity to contest the earlier suit, was constitutionally and legally entitled to.

The Illustration That Captures the Contrast

Illustration (d) to Section 43 / Section 37 BSA sharpens this point through an illuminating contrast:

"A has obtained a decree for the possession of land against B. C, B's son, murders A in consequence. The existence of the judgment is relevant as showing the motive for a crime."

Here, the decree is not used against C as proof that A owns the land — it is used only to show why C had a motive to murder A. The decree remains inadmissible as proof of title against C, but the fact of its existence becomes relevant for an entirely different purpose — circumstantial evidence of motive under Section 8 IEA / Section 6 BSA.

This is the precise equilibrium that the law strikes. A judgment binds only those who were parties to it or who claim through them. For the rest of the world, it is a historical fact — a transaction that occurred in a court — which may be relevant for particular collateral purposes, but which can never operate as a decisive legal sword against those who had no voice in its making.

The Connecting Thread

Both problems, placed side by side, reveal the same truth. The conviction of B does not bind C in the bigamy case; the declaratory decree against B does not bind C in the property suit. In each case, the stranger was denied the elementary right to appear, contest, and be heard. The law — through Section 43 IEA / Section 37 BSA — honours this denial by shielding the stranger from the judgment's reach. The exceptions under Sections 41 and 42 exist because certain questions — status, public rights — demand finality for the benefit of society at large. But those exceptions are strictly bounded, and wherever the facts fall outside those boundaries, the timeless principle of audi alteram partem reasserts itself with full vigour.
