Contract – Duress. A lack of reasonable grounds in resisting a claim of payment of commission was insufficient to engage the doctrine of economic duress where the pressure involved the commission or threat of lawful acts. In so holding, the Court of Appeal, Civil Division, allowed the appellant Pakistan International Airlines Corporation's appeal and held that the reasons given by the judge were not capable of sustaining his conclusion that the respondent family run travel agent had been entitled to avoid the New Agreement with the appellant on the grounds of economic duress.
