It's true that our only opportunity to have recourse to the court system lies under
section 68 of the Arbitration Act 1996, which provides for the possibility of a challenge "on the ground of serious irregularity affecting the tribunal, the proceedings or the award" (see section 68(1)).
The lawyers on here have generally opined that this is extremely unlikely because it's very rare in practice and tends to involve fairly egregious conduct on the part of an arbitral body. To confer a right on a party to arbitration proceedings to appeal to the civil court system against a ruling other than in fairly exceptional circumstances would be inimical to the whole essence of arbitration, which is to avoid the courts.
However, it's worth noting that, under section 68(2)(a) of the 1996 Act, a "failure by the tribunal to comply with section 33" of the Act is a "serious irregularity" if it will "cause substantial injustice to the applicant".
Section 33 of the 1996 Act imposes a general duty on a tribunal to "act fairly and impartially as between the parties, giving each party a reasonable opportunity of putting his case and dealing with that of his opponent" (see section 33(1)(a)).
Under section 33(2), a tribunal must "comply with that general duty in conducting the arbitral proceedings, in its decisions on matters of procedure and evidence and in the exercise of all other powers conferred on it".
So there is legal protection for us in that. It would take exceptional circumstances for it to become relevant in our case, but it's not true to say that any decision, whatever the available evidence for it, would be fine as long as there's no actual procedural impropriety.
If a tribunal handed down an award that could be demonstrated to a court to be a decision that could not have been taken by a reasonable tribunal acting fairly based on the evidence presented, the court would uphold an appeal. It's a high bar and if the members of the panel act professionally it shouldn't apply, but you never know.
The PL's panel will be well aware that if they give us any scope to bring into play the possibility of an appeal under section 68, we'll be all over it. That's something that will hopefully keep them honest (or at least relatively so).
