The principle of party autonomy forms the cornerstone on which arbitration is based. The jurisdiction of an arbitral tribunal to decide a dispute between parties is derived from the agreement reached between those parties to refer the differences between them to arbitration. It is not uncommon for challenges to the jurisdiction of a tribunal to be brought, either during the arbitration itself or in the course of enforcement proceedings. Come and hear a panel of experts discuss their experiences in bringing, resisting and deciding jurisdictional challenges, in their capacities as counsel and arbitrator, in the context of international commercial arbitrations and investor state arbitrations. The discussion will cover some of the most recent court judgments on the subject, including those of the UK Supreme Court in Dallah (supra), the Singapore Court of Appeal in PT First Media v Astro Nusantara [2014] 1 SLR 372 and the US Supreme Court in BG Group v Republic of Argentina 572 US (2014).
