Investment treaty arbitration disputes may be restrained only exceptionally, while jurisdictional and abuse objections should go to the tribunal.

Civil courts may retain limited jurisdiction over treaty-based investment arbitration disputes where Indian jurisdiction is otherwise made out, but there is no inherent statutory bar to considering such matters. An investor-state arbitration agreement derived from a treaty is treated as a sui generis contractual arrangement, not a treaty itself. Anti-arbitration injunctions may issue only in exceptional cases of clear oppression, vexation or abuse, and multiple claims within a vertical corporate group are not per se abusive where consolidation can address duplication risks. Once the treaty tribunal is constituted, objections to abuse and jurisdiction should ordinarily be raised there under kompetenz-kompetenz, so the interim restraint was vacated and the suit became infructuous.

Issues: (i) whether the Court had jurisdiction over the defendant and the subject matter of the dispute; (ii) whether there was any threshold bar or inherent lack of jurisdiction to deal with bilateral investment treaty arbitrations and whether the investment arbitration agreement was itself a treaty; (iii) whether courts in India could restrain bilateral investment treaty arbitrations alleged to be oppressive, vexatious, inequitable or an abuse of process; (iv) whether multiple claims by entities within the same vertical corporate chain were per se abusive and whether consolidation was an adequate answer; (v) whether the plaintiff was bound to raise the plea of abuse before the arbitral tribunal under kompetenz-kompetenz; (vi) whether the interim injunction order was vitiated by suppression; and (vii) whether the suit had become infructuous after constitution of the tribunal.

Issue (i): whether the Court had jurisdiction over the defendant and the subject matter of the dispute.

Analysis: The Court held that the place-of-suing provisions of the Code of Civil Procedure, 1908, together with the defendant's business and investment connections in India and the pleaded cause of action, were sufficient to found jurisdiction. It also treated the corporate group and Indian subsidiary as part of a single economic entity for the limited purpose of assessing jurisdictional reach and held that the defendants had purposefully availed themselves of Indian jurisdiction.

Conclusion: The Court held that it had jurisdiction over the defendants in personam and over the subject matter of the dispute, in favour of the plaintiff.

Issue (ii): whether there was any threshold bar or inherent lack of jurisdiction to deal with bilateral investment treaty arbitrations and whether the investment arbitration agreement was itself a treaty.

Analysis: The Court held that there was no express or implied statutory ouster of civil jurisdiction in relation to such disputes. It further held that an investor-state agreement to arbitrate, though derived from a treaty, is not itself a treaty but a sui generis contractual arrangement governed by principles of international law. The Court also held that Indian courts are not barred from interpreting unincorporated treaty-based arbitration arrangements where necessary.

Conclusion: There was no threshold bar or inherent lack of jurisdiction, and the investment arbitration agreement was not itself a treaty, in favour of the plaintiff.

Issue (iii): whether courts in India could restrain bilateral investment treaty arbitrations alleged to be oppressive, vexatious, inequitable or an abuse of process.

Analysis: The Court recognised an inherent power to grant anti-arbitration injunctions in exceptional cases, but emphasised that such power must be exercised with great caution. It held that the concepts of abuse of process, vexation and oppression are recognised both in equity and public international law, yet restraint is justified only where the proceedings are positively shown to be oppressive, vexatious, inequitable or abusive. On the facts, the existence of parallel treaty proceedings and the defendants' conduct did not justify injunctive relief, particularly in view of the availability of the arbitral forum itself to decide such objections.

Conclusion: The Court held that it could, in principle, restrain such proceedings, but no injunction was warranted on the facts, in favour of the respondent.

Issue (iv): whether multiple claims by entities within the same vertical corporate chain were per se abusive and whether consolidation was an adequate answer.

Analysis: The Court held that multiple claims in a vertical corporate structure are not per se vexatious or abusive. It found that the allegation of abuse depended on the particular facts and that, in this case, the risk of double recovery or conflicting awards could be addressed by consolidation before the treaty tribunal. The Court accepted the defendants' undertaking to seek consolidation if the plaintiff consented.

Conclusion: Multiple claims were not per se abusive and consolidation was treated as a sufficient practical answer, in favour of the respondent.

Issue (v): whether the plaintiff was bound to raise the plea of abuse before the arbitral tribunal under kompetenz-kompetenz.

Analysis: The Court held that the tribunal constituted under the treaty was competent to rule on its own jurisdiction and on any abuse-of-process objection. Since the tribunal had been constituted, the challenge to invocation and any jurisdictional objection should be raised before that tribunal rather than before the civil court.

Conclusion: The plaintiff was required to raise the objection before the arbitral tribunal, in favour of the respondent.

Issue (vi): whether the interim injunction order was vitiated by suppression.

Analysis: The Court found that certain later correspondence had not been disclosed when interim relief was first sought, but it gave the plaintiff the benefit of doubt because the plaint had been prepared earlier and the omission was not held to be wilful or malicious suppression.

Conclusion: No finding of wilful suppression was recorded against the plaintiff, in favour of the plaintiff.

Issue (vii): whether the suit had become infructuous after constitution of the tribunal.

Analysis: Once the tribunal was fully constituted, the original apprehension that it might be formed without Indian participation no longer survived. The Court held that the proper forum for the abuse-of-process objection was the arbitral tribunal itself.

Conclusion: The suit had become infructuous.

Final Conclusion: The Court declined to grant an anti-arbitration injunction, vacated the interim restraint, and left the abuse-of-process objection to be decided by the constituted treaty tribunal.

Ratio Decidendi: An investor-state treaty arbitration is a sui generis contractual arrangement deriving from a treaty, and although civil courts retain limited jurisdiction to restrain oppressive or abusive proceedings, the arbitral tribunal itself should ordinarily decide objections to its own jurisdiction under kompetenz-kompetenz, especially once the tribunal has been constituted.
