Order Rejecting Impleadment Of Third Party Based On Jurisdictional Plea Is Appealable Under Section 37 Arbitration Act: Bombay High Court

Bombay High Court, in a significant ruling, held that an order of an arbitral tribunal rejecting an application to implead a third party as a "veritable party" is appealable under Section 37(2)(a) of the Arbitration and Conciliation Act, 1996.

A single-judge bench of Justice Somasekhar Sundaresan observed that such a rejection, predicated on the tribunal’s lack of jurisdiction over the non-signatory, constitutes the acceptance of a plea under Section 16, thereby triggering the statutory right of appeal. The Court noted that excluding a necessary party at the threshold could lead to severe hardship and the risk of de novo proceedings after an award is passed.

The dispute arose between Hind Offshore Private Limited and OCS Services (India) Private Limited regarding Charter Party Agreements for vessels used in ONGC projects. In the ensuing arbitration, Hind Offshore sought to implead Planet Support Services, a group company of OCS Services, alleging it was a necessary party due to its involvement in contract negotiations and performance. The Arbitral Tribunal rejected the impleadment application on November 19, 2025, leading Hind Offshore to challenge the order before the High Court.

The primary question before the court was whether a challenge is maintainable under Section 37(2)(a) of the Act against an order rejecting the impleadment of a third party. The court was also called upon to determine if, on merits, the "Group of Companies" doctrine was applicable to bind the non-signatory entity in this specific factual context.

Maintainability Of Appeal Under Section 37(2)(a)

The Court first addressed the preliminary objection regarding the maintainability of the petition. It analyzed the interplay between Section 16, which deals with the competence of a tribunal to rule on its jurisdiction, and Section 37, which provides for appealable orders. The Court noted that while a rejection of a jurisdictional plea is not immediately appealable, the "acceptance" of such a plea is.

Court Explains Statutory Right Of Check And Balance

Justice Sundaresan observed that if a tribunal rules it does not have jurisdiction, the matter ends there for that party, necessitating a check and balance. The bench remarked that this rejection can take the form of a rejection of jurisdiction over the entire dispute or over a specific party arraigned in the proceedings. In either case, the party seeking to include the third party must have a right to challenge that ruling.

Avoiding De Novo Proceedings And Judicial Waste

The Court highlighted the practical necessity of allowing such appeals to prevent future procedural breakdowns. It noted that if arbitration proceedings are conducted entirely without a party who is later found to be necessary, the parties would be put to severe hardship. The bench agreed with the view that waiting until the Section 34 stage to challenge such a finding would defeat the object of time-bound dispute resolution.

"The rejection of the application for impleadment brings a dead end to the proceedings so far as the non-signatory seeking impleadment is concerned."

Merits And The Group Of Companies Doctrine

Turning to the merits, the Court examined whether Planet Support could be bound by the arbitration agreement. Hind Offshore argued that the common ownership under Mr. Raju Shete and email correspondence showing Planet Support's involvement in negotiations made it a "veritable party." However, the Court cautioned that mere group affiliation is insufficient to bypass the principle of separate legal personality.

Distinction Between Support Services And Consent To Arbitrate

The bench found that the emails relied upon by the Petitioner merely indicated that Planet Support played a "vendor management" or "support service" role. The Court noted that the record did not suggest Planet Support made critical decisions or controlled the bargain. Justice Sundaresan emphasized that the "Group of Companies" doctrine requires a fact-specific inquiry into the mutual intention of all parties to bind the non-signatory to the arbitration agreement specifically.

Need For Specific Cause Of Action Against Non-Signatory

The Court criticized the Petitioner’s approach of seeking impleadment without clearly articulating a cause of action against the third party. It observed that Planet Support could potentially be a witness under Section 27 of the Act, but dragging it into the proceedings as a party required more than just showing it was a group company. The Court held that the Petitioner failed to frame a mixed question of fact and law that necessitated impleadment.

> "The existence of a group companies is one of the essential factors to determine whether the conduct amounts to consent but membership of a group is not sufficient in itself."

Tribunal's Findings Not Perverse

Regarding the allegation that the tribunal misread the record concerning a "sham" services agreement, the Court held that even if an error existed, the needle did not turn in the Petitioner's favour. The Court found no prima facie evidence to substantiate that the inter-company agreement was fabricated. It concluded that the tribunal’s order contained an "excellent summary" of the law and applied it correctly to the facts.

The High Court dismissed the petition, holding that while the appeal was maintainable in law, it failed on its merits. The Court affirmed that the Petitioner did not establish a "discernible veritable privity" between the third party and the arbitration agreement. The bench left the issue of costs for this round of litigation to be determined by the Arbitral Tribunal during the final proceedings.
