The document discusses the jurisdiction of arbitrators in arbitration. It makes three key points: 1. Arbitration agreements grant jurisdictional powers to arbitrators, with jurisdiction established through party consent to private resolution over court litigation. 2. The construction, scope and validity of the arbitration agreement are important for determining the arbitral tribunal's jurisdiction. 3. In international arbitration, the tribunal initially decides its own jurisdiction, though courts can review jurisdictional decisions and refuse enforcement for lack of jurisdiction.
