Compton Beauchamp Estates Ltd v Spence

An arbitration award must explain why the essential issues were decided as they were. In an expert valuation dispute, the reasons must engage with the principal controversial issues, but need not address every argument or evidential detail. A deficient explanation constitutes a serious irregularity under section 68(2)(h) of the Arbitration Act 1996 only where it causes or will cause substantial injustice. The court must support the arbitral process and intervene only in an extreme case. Case-management directions and evidential rulings need not ordinarily be included in the reasons for the award. An expert arbitrator may use his expertise to evaluate and adjust evidence, provided he does not introduce undisclosed evidence.

The claimant landlord challenged an agricultural rent-review award under sections 68 and 69 of the Arbitration Act 1996. The arbitration determined the rent payable for an agricultural holding under the Agricultural Holdings Act 1986. The arbitrator assessed the rent at £34,800 per annum and later corrected a clerical discrepancy and supplied further calculations under section 57(3).

Permission to appeal on questions of law was refused by Newey J. The claimant nevertheless alleged serious irregularities, including inadequate reasons, procedural unfairness, inappropriate evidential directions, failure to deal with issues and impermissible use of the arbitrator’s own expertise. The central issue was whether any irregularity caused substantial injustice.

1. Claim dismissed. None of the alleged irregularities was established with the necessary consequence of substantial injustice.
2. Section 52(4) of the Arbitration Act 1996 requires a reasoned award unless reasons are dispensed with. The arbitrator must explain why the essential issues were decided as they were. The award need not address every submission or set out every step of the reasoning.
3. The standard is contextual. Parties familiar with the evidence and arguments may understand concise reasoning that would be inadequate in another case. In an expert valuation dispute, the arbitrator should explain the principal basis for preferring one expert’s approach, but need not provide a court-like analysis of every figure.
4. A failure to comply with the reasons requirement may fall within section 68(2)(h), but section 68 remains a long-stop remedy. The applicant must prove substantial injustice. Inadequate reasoning does not automatically establish that threshold.
5. The award’s reasoning was poor, but, read with the parties’ knowledge of the issues and the further reasons supplied under section 57(3), it was generally sufficient. Any unexplained detail, including the precise livestock calculation and the assessment of one expert’s reliability, was minor and caused no substantial injustice.
6. The sequential exchange of expert reports and the evidential directions were matters for the arbitrator under sections 33 and 34. They caused no procedural unfairness or substantial injustice. The reasons for such case-management directions did not form part of the reasons for the award required by section 52(4).
7. An arbitrator appointed for expertise may use that expertise to evaluate and adjust competing expert evidence. The claimant did not establish that the arbitrator introduced undisclosed evidence or acted contrary to natural justice.
8. The court declined to remit the award under section 70(4). The award was dismissed, with costs to be dealt with by agreement or written submissions.

The claimant applied to the High Court under sections 68 and 69 of the Arbitration Act 1996. High Court (Chancery Division): the claim was dismissed. Newey J had previously refused permission to appeal from the arbitration award.
