“[T]he expression ‘territorial law’ … is not confined to the positive rules that regulate acts and events occurring within the jurisdiction, but includes also rules for the choice of law. English rules for the choice of law are part of the law of England and when a court, for instance, tests the substantial validity of a contract made by two foreigners in Paris by reference to French law, it applies a rule imposed by the English sovereign and it may accurately be described as putting into force part of the territorial law of England.” G.C. Cheshire, Private International Law 32 (6th ed. 1961).
