Investor-State Arbitration In Singapore
1. Introduction
Investor–State Arbitration (ISA) is a mechanism that allows a foreign investor to bring claims directly against a host State for breach of obligations under treaties such as Bilateral Investment Treaties (BITs) or Free Trade Agreements (FTAs).
Singapore has emerged as a prominent seat and venue for investor–State arbitration due to its neutrality, strong legal framework, and pro-arbitration judiciary.
