A company signed a contract. Its sister firm was dragged into arbitration. The Supreme Court just rewrote the rules.

ONGC paid Rs.55.78 crore in customs duty. The contractor's vessel left India without finishing the paperwork. ONGC wanted the sister company to pay — but the sister said, 'We never signed.' The Supreme Court just decided: sometimes a signature isn't needed.

The vessel sat in Indian waters. M/s Discovery Enterprises Pvt. Ltd. (DEPL) operated it for ONGC. The government wanted Rs.55.78 crore in customs duty on the import. ONGC paid it — expecting DEPL to claim a duty drawback (a refund of customs duty when goods are re-exported) once the vessel left. DEPL never filed the paperwork. The vessel sailed. The refund window closed. ONGC held a receipt for a duty it should never have paid. The vessel's departure log recorded its exit from Indian waters — and with it, the chance for a smooth reimbursement slipped away.

When the vessel sailed without paperwork

The contract between ONGC and DEPL was straightforward. DEPL would operate the vessel. ONGC would pay. The customs duty arrangement was central: ONGC paid upfront, DEPL would handle the drawback claim. DEPL failed to complete the formalities. The vessel left Indian waters. The window for claiming the drawback closed. ONGC was left with a Rs.55.78 crore hole in its accounts.

ONGC did not go after DEPL alone. It went after Jindal Drilling & Industries Ltd. (JDIL). ONGC's argument: DEPL and JDIL were part of the same group — the DP Jindal Group. They shared directors, offices, control. JDIL, ONGC alleged, was the real force behind DEPL. Two companies, one economic entity. If DEPL could not pay, JDIL should. The discovery application ONGC filed asked the tribunal to order both companies to produce internal records — shareholding patterns, board resolutions, inter-company correspondence — that would show how deeply JDIL controlled DEPL. The application sat on the tribunal's table, unaddressed, while the jurisdictional question was decided.

The sister company's defence: 'We never signed'

JDIL's response was simple: show us the contract with our signature. There was none. JDIL was not a signatory. Basic contract law says a person who has not signed cannot be forced into arbitration. JDIL invoked Section 16 of the Arbitration and Conciliation Act, 1996 (the power of an arbitral tribunal to rule on its own jurisdiction). The tribunal, JDIL said, had no authority over a non-signatory. The company's lawyers argued that the corporate veil (the legal separation between a company and its owners or affiliates) could not be lifted without clear evidence — evidence ONGC had not yet produced.

ONGC filed a discovery application — asking the tribunal to order JDIL and DEPL to produce internal records showing their relationship. ONGC wanted to prove JDIL controlled DEPL so completely that the corporate veil should be lifted. The tribunal had this application. It also had ONGC's plea to apply the "group of companies doctrine" — a legal principle that says companies within the same group can be bound by an arbitration agreement even if they did not sign it, if circumstances show they intended to be bound.

The tribunal's shortcut

The Arbitral Tribunal issued an interim award. The document — a few pages long — accepted JDIL's jurisdictional challenge and deleted JDIL from the proceedings. The tribunal ruled it lacked jurisdiction over a non-signatory based on Sections 2(1)(h) (which defines "party") and Section 7 (which defines an arbitration agreement). It did not decide ONGC's discovery application. It did not examine the group of companies doctrine. It simply said: JDIL did not sign, so JDIL is out. The tribunal's reasoning was crisp but incomplete — it skipped over the very evidence that could have changed the outcome.

ONGC appealed to the Bombay High Court under Section 37 of the Act (which lists orders that can be appealed). The High Court upheld the tribunal. ONGC approached the Supreme Court.

Why the Supreme Court stopped the tribunal

The bench — Justice Dr. Dhananjaya Y. Chandrachud, Justice Surya Kant, and Justice Vikram Nath — delivered judgment. The courtroom fell silent as the court outlined three fundamental errors that vitiated (invalidated) the entire interim award.

First, the discovery application. ONGC had asked the tribunal to order JDIL and DEPL to produce documents showing their relationship. This was directly relevant to whether the group of companies doctrine could apply. The tribunal deferred the application — "we will decide it later" — and then ruled on jurisdiction without those documents. The Supreme Court held this was a procedural error that vitiated the entire interim award. A tribunal cannot decide whether it has jurisdiction while refusing to look at evidence that might prove jurisdiction exists. The court noted that the tribunal's approach defeated the purpose of a fair hearing — evidence must be considered before a jurisdictional ruling, not after.

Second, the group of companies doctrine. The tribunal ruled without examining the legal foundation of this doctrine. The Supreme Court noted the doctrine has been recognised in Indian precedents — Chloro Controls India Pvt. Ltd. v. Severn Trent Water Purification Inc. (2013) and Cheran Properties Ltd. v. Kasturi & Sons Ltd. (2018). The doctrine asks whether the mutual intention of the parties was to bind both the signatory and the non-signatory affiliate. This requires examining factors: the relationship between the companies, the commonality of the subject matter, the composite nature of the transaction, the actual performance of the contract. The tribunal skipped this analysis entirely. The court emphasised that the group of companies doctrine is not a presumption — it is a fact-based inquiry that demands evidence.

Third, the deferral of ONGC's applications. The tribunal had multiple applications from ONGC — not just the discovery request but others seeking to establish JDIL's role. The tribunal deferred all of them and then ruled on jurisdiction. The Supreme Court held this defeated the purpose of a fair hearing. If the tribunal needed to decide jurisdiction first, it should have at least considered the material ONGC wanted to present. The court described this as a "procedural shortcut" that could not stand.

The ratio: When a non-signatory can be bound

The Supreme Court laid down the governing principle in clear terms. The court held: "An arbitration agreement entered into by a company within a group of companies can bind non-signatory affiliates if circumstances demonstrate mutual intention to bind both signatory and affiliated non-signatory parties." This is not automatic — it depends on evidence. The court listed five factors to guide this inquiry: (i) mutual intent of the parties; (ii) the relationship of the non-signatory to the signatory; (iii) commonality of the subject matter; (iv) the composite nature of the transaction; and (v) the actual performance of the contract. Each factor must be examined on the facts of the case — there is no shortcut.

The court also clarified the standard of review in appeals under Section 37(2)(a) against a tribunal's acceptance of a jurisdictional plea. Such an appeal is not constricted by the grounds available under Section 34 (which governs challenges to final awards). But the court must give due deference to the tribunal's reasoning — the Arbitration Act empowers tribunals to rule on their own jurisdiction. Deference does not mean blind acceptance. It means the court examines whether the tribunal applied the correct legal test and considered relevant material. In this case, the tribunal had failed on both counts.

What this means for every commercial contract

For companies operating through group structures — most large Indian businesses do — this judgment changes the risk calculus. A sister company that never signed a contract can now be dragged into arbitration if the facts show it was intimately involved in the transaction. The key is evidence: shared management, common offices, intertwined finances, actual involvement in performance. The group of companies doctrine is now firmly embedded in Indian arbitration law, but its application depends on the facts of each case.

For parties seeking to bind a non-signatory, the lesson is procedural: file your discovery application early. Ensure the tribunal decides it before ruling on jurisdiction. A tribunal that shortcuts this process risks having its entire jurisdictional ruling set aside. The Supreme Court's judgment sends a clear message: procedural fairness is not optional — it is the foundation of a valid arbitral award.

THE PLAY: If you want to bind a non-signatory affiliate to an arbitration agreement, file a discovery application for documents showing the relationship before the tribunal rules on jurisdiction — and insist on a decision before the jurisdictional hearing.

The vessel left Indian waters years ago. The Rs.55.78 crore remains unrecovered. The Supreme Court has given ONGC a second chance to prove that sometimes, in a group of companies, a signature is just a formality. The question now: will the documents tell a different story? The tribunal's interim award has been set aside, and the arbitration will resume — this time with the evidence ONGC always wanted to present. The courtroom doors remain open.
