Interaction Between The Arbitration Act And The International Arbitration Act
📌 1. Introduction: AA and IAA
Singapore has two main statutes regulating arbitration:
Arbitration Act (AA), Cap. 10, 2002 Rev Ed
Governs domestic arbitrations, i.e., arbitrations seated in Singapore where parties are Singaporean or the contract is primarily domestic.
International Arbitration Act (IAA), Cap. 143A, 2002 Rev Ed
Governs international arbitrations seated in Singapore, incorporating the UNCITRAL Model Law.
Applies to disputes with an international element, such as cross-border contracts.
Key question: How do the AA and IAA interact, and when does one apply over the other?
📌 2. Legal Principles Governing Interaction
🔹 (A) Territorial and Subject-Matter Distinction
IAA applies if:
Arbitration is seated in Singapore, and
The dispute has an international element (e.g., parties from different countries, foreign governing law, cross-border trade).
AA applies to purely domestic arbitrations, including domestic contracts between Singaporean parties.
Principle: The IAA and AA do not conflict; IAA governs international cases, AA governs domestic cases.
🔹 (B) Domestic vs International Arbitration
Domestic arbitration: Fully governed by AA.
International arbitration seated in Singapore: IAA applies as the lex arbitri, but the AA may apply subsidiarily to fill gaps.
Courts may apply AA provisions for procedural matters not addressed by IAA.
🔹 (C) UNCITRAL Model Law and IAA
IAA adopts UNCITRAL Model Law (with modifications) to provide modern procedural rules.
AA is pre-UNCITRAL and more traditional in approach.
Example: Sections on setting aside awards
IAA s24: Setting aside on limited grounds (Model Law s34)
AA s24: Broader common law powers for domestic awards
🔹 (D) Court Support and Supervision
Singapore courts have supervisory powers under both AA and IAA:
Section 6 of AA / Section 6 of IAA: Court may assist in taking evidence, compelling attendance, enforcing interim measures.
IAA explicitly supports recognition and enforcement of foreign awards (NY Convention incorporated).
Principle: Singapore courts treat both statutes as complementary, with the IAA being dominant for international arbitrations.

📌 4. Practical Comparison Between AA and IAA
| Feature | AA (Domestic) | IAA (International) |
|---|---|---|
| Scope | Domestic arbitrations | International arbitrations seated in Singapore |
| Basis | Singapore law only | Incorporates UNCITRAL Model Law |
| Court intervention | Broader powers | Limited to Model Law grounds, more restrained |
| Enforcement | Domestic awards | Domestic + foreign awards (NY Convention) |
| Interim measures | Available under AA s6 | Available under IAA s6 |
| Setting aside | AA s24 – broader | IAA s24 – limited to Model Law grounds |
📌 5. Interaction Principles
International arbitration → IAA primary, AA subsidiary
Procedural gaps can be filled by AA.
Domestic arbitration → AA exclusive
Court powers: Both statutes allow court assistance, but IAA sets narrower grounds for setting aside.
Cross-border contracts: Always check if arbitration is “international” → IAA applies.
Awards enforcement: IAA provides automatic recognition under the NY Convention, whereas AA awards rely on domestic enforcement rules.
📌 6. Summary
AA governs domestic arbitrations; IAA governs international arbitrations in Singapore.
IAA adopts UNCITRAL Model Law, while AA is more traditional.
Singapore courts may apply AA subsidiarily in international cases to fill procedural gaps.
Judicial intervention is more limited under IAA than AA.
Case law confirms: IAA → primary law for international arbitrations; AA → for domestic or supplementary purposes.
Practitioners must identify the “international element” to determine which statute governs.
