The court considered a provision that a commission agent would be paid commission following the termination of his agency provided that he did not within a year become an independent intermediary or work for a competitor. Here the suspension of payment was directly related to the agent’s activity after he had ceased to act for the principal, and was held to be in restraint of trade as it could not be justified as in reasonable protection of the principal’s trade interest.
Millett LJ observed: ‘Although the question is described as one of severance it is important to bear in mind that we are not concerned to decide how much of an offending restriction should be struck down. In such a case the question is to what extent can the party who imposed the restriction enforce those parts of it which are not in unreasonable restraint of trade. We are concerned with a very different question, namely, whether the party who has been freed from an invalid restraint of trade can enforce the remainder of the contract without it.’
It was the employee (or agent) who was seeking severance in the Sadler and Marshall cases; and therefore there was no relevance in the public policy reasons for restricting severance when sought by overbearing employers who had required their employees to subscribe to extravagant restraints.
