Ship-owners formed an association which in this action others claimed to be a tortious conspiracy.
Held: There is a cause of action against the conspirators where there is an agreement which constitutes an indictable conspiracy and that agreement is carried into execution by the conspirators by means of an unlawful act or acts which produce private injury to the claimant. ‘[M]alicious’ was not to be given its ordinary meaning (malice in fact), but rather a technical legal meaning (malice in law), meaning an intention to carry out an act that was wrongful in order to damage another or to the detriment of another, or to hurt another. Bowen LJ: ‘No man, whether trader or not, can however justify damaging another in his commercial business by fraud or misrepresentation. Intimidation, obstruction and molestation are forbidden; so is the intentional procurement or violation of individual rights, contractual or other, assuming always that there is no just cause for it . . but the defendants have been guilty of none of these acts. They have done nothing more against the plaintiffs than pursue to the bitter end a war of competition waged in the context of their own trade. To the argument that a competition so pursued ceases to have a just cause or excuse when there is ill-will or a personal intention to harm it is sufficient to reply (as I have already pointed out) that there was here no personal intention to do any other than such as was necessarily involved in the desire to attract to the defendant’s ships the entire tea freights of the ports.’
