The question of whether two parties have actually agreed to arbitrate any disputes is one for judicial determination, because if the parties have not agreed to arbitrate then the arbitrator would have no authority. Where there is an arbitration agreement, doubts concerning "the "scope" of arbitrable issues should be resolved in favour of arbitration", but issues regarding whether a "claim" falls within the scope of arbitrable issues is a judicial matter, unless the parties have expressly agreed that the arbitrator may decide the scope of his or her own authority. General arbitration clauses, such as an agreement to refer to arbitration any dispute "arising from" or "related to" a particular contract, do not authorise an arbitrator to determine whether a particular issue arises from or relates to the contract concerned.
