Derivative claimants cannot invoke Section 10 when their transferor is party to both suits.

The plaintiff, owner of premises at 19 Netaji Subhas Road, Kolkata, had conveyed two portions of the third floor to defendant no. 2.

Defendant no. 2 subsequently conveyed portions to defendants nos. 3 and 4.

In an earlier suit against defendants nos. 1 and 2, the plaintiff sought, among other reliefs, declarations concerning the scope and validity of the earlier conveyances, including cancellation of those deeds. That suit remained pending.

In the later suit, the plaintiff challenged the transfers to defendants nos. 3 and 4 and sought cancellation of the relevant deeds, recovery of possession and other reliefs.

Defendants nos. 3 and 4, neither of whom was a party to the earlier suit, separately applied under Section 10 of the Code of Civil Procedure (CPC) to stay the later suit.

1. Whether the matters in issue in the later suit were directly and substantially in issue in the earlier suit, such that Section 10 CPC required the later suit to be stayed

2. Whether defendants nos. 3 and 4, who were not parties to the earlier suit but claimed through defendant no. 2, could maintain applications under Section 10 CPC to stay the later suit

Section 10 CPC prohibits a court from proceeding with the trial of a suit where the matter in issue is directly and substantially in issue in a previously instituted, pending suit between the same parties, or parties litigating under the same title, before a court competent to grant the relief claimed.

The provision aims to prevent parallel trials and conflicting findings; the key test is whether a final decision in the earlier suit would operate as res judicata in the later suit.

As explained in Aspi Jal v. Khushroo Rustom Dadyburjor, Section 10 applies only where the entire subject matter in controversy is the same; identity of some issues alone is insufficient.

The court also relied on Bepin Behari Mozumdar v. Jogendra Chandra Ghosh and Adhish Chandra Sinha v. Hindusthan Gas & Industries Ltd., which distinguish the entire subject matter in controversy from individual questions common to both suits.

The court found that the earlier suit principally concerned whether the plaintiff had conveyed the open terrace and roof areas, and whether the conveyances to defendant no. 2 were incomplete because the full consideration had allegedly not been paid.

The later suit additionally concerned the subsequent transfers to defendants nos. 3 and 4 and the reliefs claimed against them.

Although the suits shared issues concerning the original conveyances and defendant no. 2’s title, the court held that the entire subject matter was not identical and that a decree in the earlier suit would not operate as res judicata against defendants nos. 3 and 4, who were not parties to it.

The court further held that defendants nos. 3 and 4 could not be treated as litigating under defendant no. 2’s title for Section 10 purposes: defendant no. 2 was itself a party to both suits and was contesting the later suit on its own defence, while the derivative claims of defendants nos. 3 and 4 depended on the determination of defendant no. 2’s title.

Both applications were dismissed, with costs of Rs. 25,000 payable by each applicant to the Calcutta High Legal Services Committee within six weeks. The court directed that the earlier and later suits be heard analogously.
