Sub judice (Latin: "under judgment") refers to a matter that is currently pending before a court of law and awaiting adjudication. Under Indian law, the doctrine of res sub judice is codified in Section 10 of the Code of Civil Procedure, 1908, which bars a court from proceeding with the trial of a suit where the same matter is directly and substantially in issue in a previously instituted suit between the same parties pending in the same or another competent court.
Legal definition
Section 10 of the Code of Civil Procedure, 1908 provides:
Section 10 — Stay of suit: No Court shall proceed with the trial of any suit in which the matter in issue is also directly and substantially in issue in a previously instituted suit between the same parties, or between parties under whom they or any of them claim, litigating under the same title, where such suit is pending in the same or any other Court in India having jurisdiction to grant the relief claimed, or in any Court beyond the limits of India established or continued by the Central Government and having like jurisdiction, or before the Supreme Court.
The provision requires five conditions to be satisfied: (i) two suits must be pending simultaneously; (ii) the matter in issue must be directly and substantially the same in both suits; (iii) the parties must be the same (or claim under the same parties); (iv) the parties must be litigating under the same title; and (v) the previously instituted suit must be pending in a court competent to grant the relief claimed.
How courts have interpreted this term
National Institute of Mental Health v. C. Parameshwara [(2005) 2 SCC 256]
The Supreme Court held that the object of Section 10 is to prevent courts of concurrent jurisdiction from simultaneously entertaining and adjudicating upon two parallel litigations involving the same cause of action, the same subject matter, and the same relief. The Court emphasised that the provision aims to avoid conflicting decisions and prevent the wastage of judicial resources.
Sarguja Transport Service v. State Transport Appellate Tribunal [(1987) 1 SCC 5]
The Supreme Court clarified that Section 10 applies only to the trial of the suit — it does not bar the institution of the later suit. The later suit can be filed and remains on the court's register, but its trial cannot proceed until the earlier suit is disposed of. The court may pass interim orders in the later suit even while the trial is stayed.
Why this matters
The doctrine of sub judice serves the critical purpose of preventing multiplicity of proceedings and the risk of conflicting judicial decisions. If two courts were to simultaneously try the same dispute between the same parties, they could arrive at contradictory conclusions — a situation that would undermine public confidence in the judicial system and create practical enforcement difficulties.
For practitioners, the sub judice rule requires careful monitoring of all pending cases involving the same parties and subject matter. Filing a second suit on the same subject matter is not illegal, but its trial will be stayed under Section 10 until the earlier suit is disposed of. This makes it strategically important to ensure that the first suit is filed in the most advantageous forum, as it will have priority.
A common area of confusion is the distinction between res sub judice (Section 10) and res judicata (Section 11). Res sub judice prevents a court from trying a matter that is pending in another court. Res judicata prevents a court from trying a matter that has already been decided by a competent court. The former is prospective (stay of trial); the latter is retrospective (bar on re-litigation). Together, they form a comprehensive framework against duplicative litigation.

Frequently asked questions
Does Section 10 CPC bar the filing of a second suit?
No. Section 10 does not bar the institution (filing) of the later suit — it only bars the trial of the later suit. The second suit can be filed, registered, and remain pending on the court's docket. However, its trial cannot proceed until the previously instituted suit is disposed of.
Can a court pass interim orders in a sub judice matter?
Yes. Section 10 operates as a stay on the trial, not on all proceedings. The court can pass interim orders, entertain interlocutory applications, and grant temporary relief even while the trial of the later suit is stayed under Section 10.
What is the difference between sub judice and res judicata?
Sub judice (Section 10 CPC) applies when a matter is currently pending in another court — it results in a stay of trial. Res judicata (Section 11 CPC) applies when a matter has been finally decided by a competent court — it bars re-litigation entirely. Sub judice is a temporary bar; res judicata is a permanent bar.
