Background
The parties formed an unincorporated joint venture to undertake a Singapore construction project, with participation shares of 30% for the applicant and 70% for the respondent. The joint venture later subcontracted work to the applicant. Their joint venture agreement and subcontract contained separate arbitration agreements: disputes under the joint venture agreement went to a SIAC tribunal, while subcontract disputes went to a sole arbitrator in a domestic arbitration.
In the subcontract arbitration, the sole arbitrator valued the applicant’s claims at S$2.06 million and the respondent’s counterclaims at S$20.48 million, but made no immediate payment order. Instead, he reserved jurisdiction to make a final payment order after the SIAC tribunal addressed contribution or indemnity under the joint venture agreement. He took the same approach in a later costs award. The applicant sought to set aside both awards under s 48(1)(a)(iv) and (v) of the Arbitration Act 2001.
The Court’s Holding
The High Court dismissed both setting-aside applications. The applicant’s principal complaint—that the arbitrator failed to decide who should pay whom—was, in substance, an infra petita complaint. Section 48(1)(a)(iv) addresses ultra petita awards, where a tribunal decides matters outside its mandate; it does not cover an alleged failure to decide matters submitted to it. Such a complaint would instead need to be advanced as a natural-justice challenge, which the applicant had not pleaded.
The court also rejected the argument that the arbitrator impermissibly delegated decision-making to the SIAC tribunal. It was common ground that the sole arbitrator had no jurisdiction over contribution and indemnity under the separate joint venture agreement. He therefore could not have delegated that power, and he had retained—not surrendered—jurisdiction to issue a payment order after the apportionment issue was addressed in its proper forum. The challenge to the form of the awards was a merits challenge, not a breach of agreed arbitral procedure; moreover, the parties had never agreed that an immediate payment order was required.
Key Takeaways
- An alleged failure by an arbitrator to decide an issue is generally an infra petita complaint, not an ultra petita challenge under s 48(1)(a)(iv) of the Arbitration Act.
- A setting-aside court will not review the merits of an arbitrator’s substantive choice of award form.
- Reserving jurisdiction to make a later payment order did not amount to delegating that decision to another tribunal.
Why It Matters
The decision reinforces Singapore courts’ narrow supervisory role in arbitration. Parties cannot turn disagreement with an arbitrator’s substantive reasoning or remedial choice into a procedural or jurisdictional setting-aside ground.
It also highlights the complications created by parallel arbitrations under separate contracts in a joint-venture structure. Where apportionment belongs under a separate agreement and before a separate tribunal, an arbitrator may reserve a payment order without exceeding the limits of the arbitral mandate.
