The Court of Appeal dismissed Alstom's appeal. Lord Justice Longmore, with whom Lord Justice Beatson and Lord Justice Sales agreed, held that the indemnity did cover AEI's liability for Mrs Oliver's claim.
The court first rejected any suggestion that there was no agreement to indemnify AEI at all. It said the 1971 resolution expressly ratified EEC's 1970 purchase of AEI's turbine generator business. The absence of a contemporaneous 1970 document, 46 years later, was neither surprising nor legally significant in itself.
The court then focused on the wording. It said the phrase against any claim arising on completed and uncompleted contracts recognised only two categories of contracts, completed and uncompleted. Its natural and ordinary meaning was broad. The court accepted that the phrase included customer contracts, but saw no reason why it could not also include contracts of employment.
The court also rejected the idea that employment contracts were linguistically outside the clause. It accepted that it may be a little unusual to describe an employment contract as completed or uncompleted, but not impossible or unintelligible. Mr Oliver's apprenticeship and employment had ended in 1961, so his contract could sensibly be treated as completed.
Context mattered too, but only as part of the interpretation exercise. The court agreed that the correct starting point was an informal and internal reorganisation within a group. In that setting, the natural inference was an out and out transfer of the entire undertaking unless the contrary was specified. The court considered it unlikely that rights and responsibilities would be split in an untidy way unless the documents clearly said so.
The court was not persuaded by Alstom's reliance on the 1959 agreement. It said that agreement did not assist in construing the 1970 transfer. Nor did the court accept speculation about whether the workforce was in fact transferred in 1970, or a late argument about rationalisation in the electricity industry. The judges treated those points as unhelpful to the construction exercise on the wording before them.
Alstom also relied on the words subject to certain reservations. The court was not persuaded. It held that those reservations referred back to reservations as to trading and rights of the turbine generator business and goodwill. On that reading, they did not relate to employment contracts and did not change the result.
The court also rejected the suggestion that the indemnity should not apply because liability to an employee would arise through employer negligence. It said negligence is the most common reason why employers are liable to employees, so that point did not narrow the clause.
