Allan v Johnson Controls Automotive (UK) Ltd

An alleged oral variation of employment-related pension terms must be established on the balance of probabilities. Where the alleged enhancement is substantial, the court may properly assess the evidence against contemporaneous documentation, the employee’s conduct and the inherent likelihood of the alleged agreement. Repeated documents stating a different entitlement, coupled with prolonged silence, may materially undermine the alleged variation. An issue of estoppel need not be determined where the alleged contractual variation is not proved.

Ian Allan claimed that an oral agreement made in April 1991 varied his employment contract so that his pension accrued at one-thirtieth of final salary per year, rather than one-fiftieth. The alleged agreement followed the defendant’s acquisition of the business in which he worked.

The evidence of the alleged conversation was largely oral. The defendant’s subsequent pension documentation consistently recorded a one-fiftieth accrual rate, and the claimant did not challenge that position until approximately 2001. The issues were whether the conversation occurred in the asserted terms, whether it amounted to a contractual variation, and whether the claimant was estopped from asserting the variation.

1. Claim dismissed. The claimant failed to establish, on the balance of probabilities, an entitlement to pension accrual at one-thirtieth per year.
2. The judge accepted that something was probably said about pensions at the April 1991 meeting, but concluded that it fell well short of an agreement to provide the enhanced benefit. The evidence was assessed in light of the substantial nature of the alleged improvement, the passage of time, the witnesses’ ability to recall events accurately, and the claimant’s understanding of pension schemes and documentation.
3. The repeated pension documents recording a one-fiftieth accrual rate were significant. The claimant understood the importance of recording and establishing pension rights, yet did not object to those documents or assert the alleged entitlement for many years. The isolated one-thirtieth calculation in a 2000 early-retirement quotation was treated as a check against Inland Revenue maxima, rather than confirmation of the alleged agreement.
4. The parties agreed that a pension contract could be varied orally and that there was no inherent consideration difficulty in a continuing employment contract. The judge therefore decided the contractual issue on the evidence of what was agreed, rather than on formality or consideration.
5. It was unnecessary to decide estoppel. The judge nevertheless indicated that the claimant’s conduct, particularly what he failed to do, did not appear capable of removing an otherwise clear contractual right. Leave to appeal was refused. Costs were awarded to the defendant, subject to detailed assessment if not agreed.
