“Saving for rights of person who takes no part in proceedings. (1) A person alleged to be a party to arbitral proceedings but who takes no part in the proceedings may question— (a) whether there is a valid arbitration agreement, (b) whether the tribunal is properly constituted, or (c) what matters have been submitted to arbitration in accordance with the arbitration agreement, by proceedings in the court for a declaration or injunction or other appropriate relief.”
“18.—Failure of appointment procedure. (1) The parties are free to agree what is to happen in the event of a failure of the procedure for the appointment of the arbitral tribunal. There is no failure if an appointment is duly made under section 17 (power in case of default to appoint sole arbitrator), unless that appointment is set aside. (2) If or to the extent that there is no such agreement any party to the arbitration agreement may (upon notice to the other parties) apply to the court to exercise its powers under this section. (3) Those powers are— (a) to give directions as to the making of any necessary appointments; (b) to direct that the tribunal shall be constituted by such appointments (or any one or more of them) as have been made; (c) to revoke any appointments already made; (d) to make any necessary appointments itself. (4) An appointment made by the court under this section has effect as if made with the agreement of the parties.”
“[12] Arbitration clauses commonly provide that unresolved disputes “should” or “shall” be submitted to arbitration. The silent concomitant of such clauses is that neither party will seek any relief in respect of such disputes in any other forum. [13] As with any issue of construction, the language and context of the particular agreement must ultimately be decisive. But clauses depriving a party of the right to litigate should be expected to be clearly worded—even though the commercial community's evident preference for arbitration in many spheres makes any such presumption a less persuasive factor nowadays than it was once. The consequence of the defendants' case would, at least in theory, be that the claimant's commencement of litigation was a breach of contract, for which the defendants proving loss could without more claim damages—though the prevalence of clauses providing that arbitration “shall” take place and the infrequency of claims for their breach may again reduce the weight of this factor. The fact remains that there is an obvious linguistic difference between a promise that disputes shall be submitted to arbitration and a provision, agreed by both parties, that “any party may submit the dispute to binding arbitration”
