“This remarkable Act was enacted to discourage the United States from seeking to enforce its competition policies by, among other means, making awards of multiple damages against persons in the United Kingdom.”
“It is clear in my view that Parliament sought to discourage what it considered to be the exorbitant effects of United States antitrust laws. The Act is concerned not only with the extra-territorial effect of such laws but also with preventing the recovery of multiple damages.” (at [33]). iii) Potter LJ in Lewis v Eliades (No 2)[2004] 1 WLR 692 (CA) considered in more detail statements in Parliament prior to the statutes enactment (at [44] – [45]) commenting at [46] that “It is notable that, so far as clause 5 was concerned, no statement appears which suggests any intention to extend the principle of unenforceability more widely than triple damages judgments or such other foreign ‘competition policy’ judgment as might be specified.”
“The judgment must further be for a sum other than a sum payable in respect of taxes or the like, or in respect of a fine or other penalty. It is well settled that an English court will not entertain an action for the enforcement, either directly or indirectly, of a penal or revenue, or other public law of a foreign country. Since “the essential nature and real foundation of a cause of action are not changed by recovering judgment upon it,” it follows that the court cannot entertain an action for the enforcement, either directly or indirectly, of a foreign judgment ordering the payment of taxes, fines or other contributions or penalties. A penalty in this sense normally means a sum payable to the State, and not to a private claimant, so that an award of punitive or exemplary damages is not penal. But it is possible that an award of multiple damages, e.g. in an anti-trust action, might nevertheless be regarded as penal at common law. If the purpose of the damages as awarded by the foreign court is to punish the defendant, enforcement of the judgment may be found to be against English public policy, with which the rule against enforcing foreign penal laws will overlap. If the foreign judgment imposes a fine on the defendant and also orders payment of compensation to the injured party (called the “partie civile” in French proceedings), the latter part of the judgment can be severed from the former and enforced in England.”
