The Singapore High Court’s decision in DSS v DST [2026] SGHC 145 addresses the situation when similarities between awards in related concurrent arbitrations may support a challenge for breach of natural justice under s 24(b) of the International Arbitration Act 1994 (2020 Rev Ed) (“IAA”).
The court dismissed the setting-aside application and held that, although substantial similarities existed between the two awards, they did not give rise to apparent bias or a breach of the fair hearing rule. The decision is important because it clarifies the applicable tests under Singapore law where related arbitrations are heard concurrently, and it emphasises both the permissibility and the limits of shared reasoning across separate proceedings.
