§ Why the law insists on an end

Interest reipublicae ut sit finis litium. It is in the interest of the State that there be an end to litigation. Courts are a public resource, and a dispute that consumes them indefinitely denies that resource to everyone else.

Nemo debet bis vexari pro una et eadem causa. No one should be vexed twice for the same cause. A defendant who has answered a claim and won is entitled not to answer it again.

The two are not the same. The first protects the system; the second protects the litigant. Together they explain why finality is enforced even where the earlier decision may have been wrong, and why it is enforced against both sides.

The finding

An issue directly and substantially in issue, heard and finally decided, is concluded between the parties

Section 11, with Explanations III and IV

The decree

The adjudication conclusively determines the rights of the parties as to the matters in controversy

Section 2(2) with Section 33 and Order XX

The lapse of the appeal period

The decree is no longer open to challenge on the merits

Articles 116 and 117, Limitation Act, 1963

The appellate decision

The trial decree merges in the appellate decree, leaving one operative decree

The doctrine of merger

Res judicata

The matter cannot be tried again between the same parties, nor may a ground that might and ought to have been raised

Section 11 and Explanation IV

Execution

The executing court takes the decree as it stands and cannot go behind it

Section 47, with Order XXI

§ Finality attaches in layers, not at a single moment

A finding may be final between the parties before the suit itself is over, which is why an interlocutory decision on an issue can bind later stages of the same proceeding.

A preliminary decree is final as to what it decides, and Section 97 provides that a party who does not appeal it is precluded from disputing its correctness in the appeal from the final decree.

An order of remand must be challenged when it is made: Section 105(2) precludes a party who did not appeal it from disputing its correctness later.

The practical lesson. A litigant who waits to raise an objection often finds that the moment for raising it has passed, and the Code says so expressly in these three places.

Appeal

The widest, but time-bound: a first appeal on fact and law, a second only on a substantial question of law, and none from a consent decree

Review

Three narrow grounds under Order XLVII Rule 1, within thirty days, to the same court, and never as an appeal in disguise

Revision

Jurisdictional error only, where no appeal lies, and since 1999 only where correction would have finally disposed of the suit

Reference

Not a challenge at all: the subordinate court's own doubt on a question of law, sent up before the case is decided

Restitution

Not a challenge to the decree but a consequence of its reversal: Section 144

Correction

Sections 152 and 153: the record is made to express what was decided, without altering the decision

§ Two situations, and they are different in kind from the others

• A decree that is a nullity. Where the court had no jurisdiction over the subject matter, there was never a valid adjudication. Its invalidity may be set up whenever and wherever it is sought to be enforced, including in execution and collaterally: Kiran Singh v. Chaman Paswan, AIR 1954 SC 340.

• A decree obtained by fraud on the court. Such a decree is non est, and may be challenged in any court, at any stage, and even in collateral proceedings: S.P. Chengalvaraya Naidu v. Jagannath, (1994) 1 SCC 1.

• Why this matters for the framing of an answer. These are not exceptions to finality. They are cases in which the conditions for finality were never satisfied: res judicata presupposes a genuine adjudication by a competent court, and neither of these was.

§ The tension, and how the Code resolves it

The objection. Finality sometimes leaves a wrong decision standing. A party with a good case who lost through bad advocacy, or a court's error that no remedy reaches, is told that the matter is closed.

The Code's answer is not to deny the cost but to price it. It provides generous remedies early: a full rehearing on fact and law in first appeal, amendment of pleadings, additional evidence in defined situations, restoration of dismissed suits, and correction of the record at any time.

And it narrows them as the case ages. By the time execution is reached, the only question is whether there is a decree to execute, not whether it was right.

The principle that reconciles the two is the one discussed in the companion topic: procedure is the handmaid of justice. The Code prefers a decision on the merits while the case is alive, and prefers certainty once it is not.
