Behind The Curtain: A Step-by-Step Guide To SIAC Arbitration Under The 2025 Rules

Choosing SIAC arbitration determines far more than the institution that will administer a dispute. It places the parties within a procedural framework that shapes how the arbitration is commenced, how the tribunal is constituted, how urgent applications are handled, how evidence is presented and, ultimately, how the award is rendered. The 2025 SIAC Arbitration Rules (“SIAC Rules”) give parties and tribunals considerable flexibility within that framework, while introducing new mechanisms designed to make proceedings faster and more proportionate. For a party contemplating arbitration, the important question is therefore not simply what the SIAC Rules provide, but how a SIAC arbitration actually unfolds in practice and what decisions need to be made at each stage.
