In the choice of law for giving obligatory force to promises or agreements, ascertaining their scope and determining their operation, English Courts have been avowedly guided by the real or presumed intention of the parties. Learned writers have urged that such a standard is alike unsound in principle and inconvenient in practice. How, they ask, can an English forum be justified in giving any legal effect to the intention of the parties until it has decided by what law efficacy is ascribed to their intentions? Why should the minds of the parties affect the question whether a foreign law operates upon an agreement made by them and translates it into rights and duties which English Courts ought to recognize and enforce? If the law of a country declares that some description of transaction shall be unlawful and of no effect, why, in a question whether that law is applicable to a particular transaction of that description brought before an English forum, should any regard be paid to the intention of the parties on the subject? How often do the parties possess any intention that their agreement shall be governed by a particular law? And, if they express such an intention, may it not be for the purpose of evading the operation of the law of a country justly claiming to control them? If an intention must be imputed where none existed, how can any certainty be found, unless by the use of presumptions producing the same effect as independent substantive rules?
