Company Law in UK Law

These considerations reflect the broader principle that the corporate veil may be pierced only to prevent the abuse of corporate legal personality. It may be an abuse of the separate legal personality of a company to use it to evade the law or to frustrate its enforcement. It is not an abuse to cause a legal liability to be incurred by the company in the first place. It is not an abuse to rely upon the fact (if it is a fact) that a liability is not the controller's because it is the company's.

I conclude that there is a limited principle of English law which applies when a person is under an existing legal obligation or liability or subject to an existing legal restriction which he deliberately evades or whose enforcement he deliberately frustrates by interposing a company under his control.

When the oil companies, as shareholders, approved what the plaintiffs' directors had done there was no cause of action because at that time there was no damage. What the oil companies were doing was adopting the directors' acts and as shareholders, in agreement with each other, making those acts the plaintiffs' acts.

As the Prudential principle is an exclusionary rule denying a claimant what otherwise would be his right to sue, the onus must be on the defendants to establish its applicability. Further, it would not be right to bar the claimant's action unless the defendants can establish not merely that the company has a claim to recover a loss reflected by the profit, but that such claim is available on the facts.
