Singapore High Court Clarifies Status of Interim Measures in Arbitration

In DLS v DLT [2025] SGHC 61, the Singapore High Court provided crucial guidance on distinguishing between interim awards and provisional measures in arbitration. The case arose from a construction dispute between a Contractor and a Sub-Contractor, with the arbitration seated in Singapore under the ICC Rules.

The Tribunal’s Orders

The Sub-Contractor obtained urgent interim measures and the Tribunal ordered as follows in its First Partial Award:

1. Monthly Payment Decision: The Contractor was ordered to pay US$172,135.54 monthly to cover operational costs, contingent on the Sub-Contractor providing security.
2. Lump Sum Decision: The Contractor was ordered to pay US$117,339.48, which was due and owing.

The Court's Analysis

The Contractor sought to set aside these orders under section 24 of the International Arbitration Act 1994 (IAA), which provides for the setting aside of awards affected by fraud or breach of natural justice. The Court's threshold question was whether the decisions were 'awards' susceptible to setting aside, or alternatively, ‘orders or directions’ under section 12 of the IAA (which are not).

The Court emphasised that the nature of a tribunal's decision is determined by substance, not form. Provisional orders or directions are inherently capable of variation and do not resolve substantive rights definitively. The Monthly Payment Decision was provisional, while the Lump Sum Decision was final, as it conclusively disposed of a claim.

Implications for Singapore's Arbitration Framework

Some jurisdictions in the US treat provisional measures as enforceable awards, due to their importance in maintaining the efficacy of arbitration. The 2006 revisions to the UNCITRAL Model Law reflect this perspective, providing a framework for recognising and enforcing interim measures across borders. Article 17H(1) of the Model Law states that interim measures should be recognised as binding and enforceable, a provision not yet adopted by Singapore.

Singapore's current arbitration framework, as demonstrated by the High Court's decision, maintains a distinction between provisional orders and final awards. However, the Singapore Ministry of Law recently concluded its public consultation on the IAA on 2 May 2025 and this may lead to reforms to the IAA, potentially enhancing the enforceability of interim measures.

Conclusion 

The High Court's ruling serves as a reminder for legal counsel to carefully consider the formulation of interim relief in an arbitration. As jurisdictions worldwide continue to evolve their arbitration laws, understanding the nuances of interim measures remains critical for effective dispute resolution.
