“[30] Arbitration is a consensual process by which the parties agree to resolve disputes between them by accepting the decision of a tribunal chosen by them or in accordance with a procedure which they have agreed. An award thus produced is final and binding on them:section 58 of the Arbitration Act 1996 . For this purpose it makes no difference whether the arbitrators’ decision is right or wrong. Althoughsection 69 of the 1996 Act permits an appeal to the court on a question of law arising out of an award, it is open to the parties to exclude any such appeal and the LCIA Rules contain such an exclusion agreement. Accordingly, when parties agree to arbitrate their differences under LCIA Rules, they agree to be bound by the arbitrators’ decision even if the arbitrators get the law or the facts wrong. The only bases on which such an award can be challenged are that the arbitrators acted without jurisdiction (section 67) or that a serious irregularity of the limited kind listed in section 68 resulted in substantial injustice. In the present case the arbitrators’ award may have been wrong in the sense indicated above, but there was no scope for Vale to challenge the dismissal of its restitutionary claim. [31] However, while the award is final and binding as between Vale and BSGR, it is not binding on third parties. It is elementary that an arbitrator cannot make an award which is binding on third parties who have not agreed to be bound by his decision (Mustill & Boyd, Commercial Arbitration, 2nd Ed (1989), pages 149-150; Russell on Arbitration, 24th Ed (2015), para 6-183). … Accordingly, it is common ground that as third parties the appellants are not bound by the arbitrators’ decision that Vale was the victim of a fraud.”
