Economic Torts in UK Law

The reasoning in Total Network leaves open the question how far the same considerations apply to non-criminal acts, such as breaches of civil statutory duties, or torts actionable at the suit of third parties, or breaches of contract or fiduciary duty. By comparison, legal duties in tort or equity will commonly and contractual duties will always be specific to particular relationships. For present purposes it is unnecessary to say anything more about unlawful means of these kinds.

To be liable for inducing breach of contract, you must know that you are inducing a breach of contract. It is not enough that you know that you are procuring an act which, as a matter of law or construction of the contract, is a breach. Nor does it matter that you ought reasonably to have done so.

Although my conclusion on the issue of unlawful means makes it unnecessary to decide the point, I would support Arden LJ's view at [127] that it is a defence to an action for conspiracy to injure by unlawful means if the defendant not only acted to protect his own interests, but did so in the belief that he had a lawful right to act as he did.

The circumstances must be such as to make the conduct sufficiently reprehensible to justify imposing on those who have brought about the harm liability in damages for having done so. Bearing that in mind, the proposition that a combination of two or more people to carry out a scheme that is criminal in its nature and is intended to cause economic harm to some person does not, when carried out with that result, constitute a tort actionable by that person is, in my opinion, unacceptable.

Professor Weir and most other writers, including Hazel Carty and Messrs Sales and Stilitz, are of the view that the gist of all the economic torts is the intentional infliction of economic harm. It is, however, very different from knowledge that economic harm will follow as a result of incidental consequences of conduct, when those consequences are not necessary steps in achieving the object of the conduct and are unsought.

But when conspirators intentionally injure the plaintiff and use unlawful means to do so, it is no defence for them to show that their primary purpose was to further or protect their own interests; it is sufficient to make their action tortious that the means used were unlawful.

The tort is an economic tort designed to place limits on the self-interested rough and tumble of the business world. Its philosophical basis appears to be that contracts should be kept rather than broken.
