Allan v Johnson Controls Automative (UK) Ltd

An appellate court reviewing findings of fact must give proper weight to the trial judge’s advantage, particularly where conclusions depend on oral evidence. It must nevertheless decide whether challenged findings or inferences are correct, and intervene where a conclusion is plainly wrong or outside reasonable disagreement. A legal misdirection removes that threshold. A trial judge may test honest testimony against inherent plausibility, contemporaneous documents and the surrounding circumstances. Honest witnesses may be mistaken, and the absence of contrary oral evidence does not require acceptance of their recollection. In an alleged oral variation of pension rights, documentary inconsistency and prolonged silence may outweigh honest oral evidence.

Mr Allan appealed against an order dated 1 February 2008 by HHJ Foster QC, sitting as a deputy High Court judge in the Queen’s Bench Division. The judge dismissed his claim against his former employer for a contractual entitlement to an enhanced pension accruing at 1/30th rather than 1/50th per year.

The trial judge accepted that Mr Allan and two supporting witnesses were honest, but concluded that their evidence did not establish a binding agreement. Mr Allan argued that this conclusion was perverse, particularly because the employer had called no witness denying the alleged agreement. The respondent also served a notice relying on estoppel by convention. The central issue was whether the factual findings and evaluation of the alleged oral agreement were open to the trial judge.

Arden LJ delivered the leading judgment. Jackson LJ and the President agreed. The appeal and the respondent’s notice were dismissed.

1. Appellate review. The approach to factual findings depends on the nature of the issue and the advantage enjoyed by the trial judge. An appellate court must review the decision, but should give particular weight to findings substantially based on oral evidence. It has greater latitude where an inference is challenged. It must intervene where a conclusion is plainly wrong or outside the bounds of reasonable disagreement. That threshold does not apply where the judge has made an error of law or misdirected himself. The approach reflected the reasoning in Assicurazione Generali spa v Arab Insurance Group plc [2003] 1 WLR 577, including the distinction drawn in Todd v Adam [2002] EWCA Civ 509, and was noted to have been approved in Datec Electronic Holdings Ltd v United Parcel Service Ltd [2007] 1 WLR 1325. The court’s powers were also consistent with rules 52.11(3) and (4) of the Civil Procedure Rules 1998.
2. Evaluation of the evidence. The judge was entitled to test the supporting oral evidence against the inherent plausibility of the alleged agreement, contemporaneous documentation and the parties’ conduct. The employer’s failure to call contrary oral evidence was a factor in Mr Allan’s favour, but was not decisive. The judge had the advantage of hearing the totality of the evidence and was not required to accept testimony merely because the witnesses were honest.
3. Pension agreement. It was accepted without challenge that a pension entitlement could in principle be varied orally. However, the absence of any written record, repeated documents stating a 1/50th accrual rate, and Mr Allan’s failure to protest for many years supported the conclusion that no binding 1/30th agreement had been made. A witness may be honest while mistaken about the accuracy of his recollection.
4. Disposition. The trial judge’s conclusion was not perverse or legally erroneous. The appeal was dismissed. The respondent’s estoppel notice was also dismissed because reliance on estoppel was unnecessary.
