 It has been argued that, in view of modern methods of communication and international trade, the weight of the "locus celebrate contractus" in assigning the governing law is diminishing.It is important to note, however, that the court is not restricted in its choice of proper law by any rigid rules, and may in appropriate cases assign to the contract some other governing law.Normally, the contract is governed by a single proper law throughout its existence, since the rights and duties of the parties would be distorted if some were to be governed by one system of law and others by another.
