Section 10 of the Code which is relevant for the purpose reads as follows:

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.

Explanation. – The pendency of a suit in a foreign Court does not preclude the Courts in India from trying a suit founded on the same cause of action.”

From a plain reading of the aforesaid provision, it is evident that where a suit is instituted in a Court to which provisions of the Code apply, it shall not proceed with the trial of another suit in which the matter in issue is also directly and substantially in issue in a previously instituted suit between the same parties.

For application of the provisions of Section 10 of the Code, it is further required that the Court in which the previous suit is pending is competent to grant the relief claimed. The use of negative expression in Section 10, i.e. “no court shall proceed with the trial of any suit” makes the provision mandatory and the Court in which the subsequent suit has been filed is prohibited from proceeding with the trial of that suit if the conditions laid down in Section 10 of the Code are satisfied.

Purpose and Object

The basic purpose and the underlying object of Section 10 of the Code is to prevent the Courts of concurrent jurisdiction from simultaneously entertaining and adjudicating upon two parallel litigations in respect of same cause of action, same subject matter and the same relief. This is to pin down the plaintiff to one litigation so as to avoid the possibility of contradictory verdicts by two courts in respect of the same relief and is aimed to protect the defendant from multiplicity of proceeding.

In National Institute of Mental Health & Neuro Sciences vrs. C. Parameshwara, (2005) 2 SCC 256 in which it has been held as follows:

“8. The object underlying Section 10 is to prevent courts of concurrent jurisdiction from simultaneously trying two parallel suits in respect of the same matter in issue. The object underlying Section 10 is to avoid two parallel trials on the same issue by two courts and to avoid recording of conflicting findings on issues which are directly and substantially in issue in previously instituted suit. The language of Section 10 suggests that it is referable to a suit instituted in the civil court and it cannot apply to proceedings of other nature instituted under any other statute.

The object of Section 10 is to prevent courts of concurrent jurisdiction from simultaneously trying two parallel suits between the same parties in respect of the same matter in issue. The fundamental test to attract Section 10 is, whether on final decision being reached in the previous suit, such decision would operate as res-judicata in the subsequent suit.

Section 10 applies only in cases where the whole of the subject-matter in both the suits is identical. The key words in Section 10 are “the matter in issue is directly and substantially in issue” in the previous instituted suit. The words “directly and substantially in issue” are used in contradistinction to the words “incidentally or collaterally in issue”.

Therefore, Section 10 would apply only if there is identity of the matter in issue in both the suits, meaning thereby, that the whole of the subject-matter in both the proceedings is identical.”

In ‘Aspi Jal v. Khusroo Rustom (2013), the court said,

“The key words in Section 10 are “the matter in issue is directly and substantially in issue in the previously instituted suit”. The test for applicability of Section 10 of the Code is whether on a final decision being reached in the previously instituted suit, such decision would operate as res-judicata in the subsequent suit.

To put it differently one may ask, can the plaintiff get the same relief in the subsequent suit, if the earlier suit has been dismissed? In our opinion, if the answer is in affirmative, the subsequent suit is not fit to be stayed. However, we hasten to add then when the matter in controversy is the same, it is immaterial what further relief is claimed in the subsequent suit.”
