“Accordingly a foreign judgment will not operate as a res judicata in England unless it is a res judicata before the foreign court according to the foreign law.”
“The European Court has affirmed on a number of occasions the existence in principle of the possibility in a suitable case of invoking article 6. The context has generally been that of extradition or expulsion of aliens seeking admission to the country concerned, but in my opinion it is capable of being applied to the enforcement in a Convention state of a judgment obtained in another state, whether or not the latter is an adherent to the Convention. No decision was cited to your Lordships in which the court went so far as to hold that an act of extradition or expulsion amounted to a breach of article 6, and in all of the reported cases the European Court has strongly emphasised the exceptional nature of such a jurisdiction and the flagrant nature of the deprivation of an applicant’s rights which would be required to trigger it.”
