Consolidation, Joinder and Multi-Party Arbitration

A modern commercial transaction rarely involves two parties and one contract. An infrastructure project has an employer, a contractor, sub-contractors, a guarantor and insurers, each bound by a different document. Litigation handles this through joinder and consolidation; arbitration cannot, because the tribunal's authority comes from consent. Part I of the Arbitration and Conciliation Act, 1996 contains no provision for either, so the answer lies in the agreement, in the institutional rules the parties adopted, or in the composite transaction analysis the courts have developed.

The four techniques, the Indian position, and the rule that governs all of them

1. The Problem

Where one event gives rise to claims under several contracts, separate arbitrations produce three difficulties. The same question of fact may be decided differently by different tribunals, so an employer may lose against the contractor on a finding that the sub-contractor was at fault and lose again against the sub-contractor on the opposite finding. The cost is multiplied, since each reference has its own tribunal and its own hearing. And evidence available in one reference may not be available in another, because a tribunal cannot compel a person who is not a party.

2. The Techniques

3. The Indian Position

There is no statutory power to join or consolidate. What exists is the following.

• Section 2(6) and Section 2(8). The parties may authorise an institution to determine a matter they are free to determine, and a reference to an arbitration agreement includes the rules referred to in it. Institutional rules providing for joinder and consolidation therefore take effect as part of the bargain.
• The composite transaction analysis. Chloro Controls India (P) Ltd. v. Severn Trent Water Purification Inc., (2013) 1 SCC 641 and Ameet Lalchand Shah v. Rishabh Enterprises, (2018) 15 SCC 678 permit several interlinked agreements implementing a single commercial arrangement to be referred together.
• Non-signatories. Cox and Kings Ltd. v. SAP India (P) Ltd., (2024) 4 SCC 1 settles that a non-signatory may be a party where the mutual intention of the parties can be inferred, which is the route by which a group company is brought into an existing reference.
• Section 8, as amended in 2015. The words any person claiming through or under him permit the reference of parties who derive title from a signatory.

4. Appointment in a Multi-Party Reference

The default model in Section 11(3), under which each party appoints one arbitrator and the two appoint the third, assumes two parties. With three or more it breaks down: either several respondents must agree on a single nominee, which one of them may refuse, or one side has more nominees than the other, which offends equality. The accepted solution, adopted in institutional rules, is that where the multiple parties cannot agree on a joint nomination, the institution appoints all the members of the tribunal, including the presiding arbitrator, so that neither side has an advantage. In an ad hoc reference the same result must be reached by an application under Section 11, and the clause should provide for it in advance.

5. Drafting

1. Use the same arbitration clause, verbatim, in every contract forming part of one transaction, including the same seat, institution, number of arbitrators and language.
2. Provide expressly that disputes under any of the related contracts may be referred to a single arbitration, and that a party to any of them may be joined.
3. Adopt institutional rules that contain joinder and consolidation provisions, and name the institution accurately.
4. Provide for appointment where there are more than two parties, so that the institution appoints the whole tribunal if a joint nomination is not made.
5. Where the contracts are made at different times, record in the later one that it forms part of the same transaction, which assists the composite analysis later.
