Next it is suggested that the Act applies in all cases where the governing law of the contract of employment is the law of Victoria, and in no other case. It is not easy to see why such a test should be selected for the purpose of construing in relation to its local operation a remedial statute of this character. Where there is what may be called a foreign element in a contract it may be necessary to refer to the law of more than one country for the purpose of determining all the questions which may arise in relation to the contract. It may be the law of one country which determines the capacity of the parties to contract, the law of another country which regulates the formalities of the contract, while a third country may supply the governing law of a contract, by which questions of material (as distinct from formal) validity, interpretation and the nature and extent of the obligations under the contract are determined. But this Act, for the reasons stated, cannot be regarded as an Act regulating contractual relations. In special cases, in the absence of any other clear indication of the intention of parliament, the governing law of a contract may be selected as the best practicable means of determining the territorial application of a statute which is essentially a statute dealing with contracts (Barcelo v. Electrolytic Zinc Co. of Australasia Ltd.[24]; Wanganui-Rangitikei Electric Power Board v. Australian Mutual Provident Society[25]). In those cases the court had to consider the applicability of a statute which altered the obligations of mortgages. The question was determined by adopting the principle that a legislature, in intervening for the purpose of varying existing contractual relations, might reasonably be supposed to be intending to deal with such obligations only where they were obligations created by contracts the governing law of which was that of the country of the legislature in question. Such a criterion, however, appears to be inapplicable to a statute which is not directed towards the alteration of obligations under existing contracts, but which is intended to prescribe a general rule of conduct for the future, within the sphere to which it is applicable, whatever may be the terms of any contracts which the parties may choose to make. As a general rule, the parties can fix their own governing law for their contracts. In Spurrier v. La Cloche[26], Lord Lindley said for the Privy Council: "That the intention of the parties to a contract is the true criterion by which to determine by what law it is to be governed is too clear for controversy." But, although this proposition is stated to be too clear for controversy, there is room for much controversy not only as to what the intention of the parties is in a particular case, but also as to the intention which the parties are allowed to have: See, for example, Cheshire, Private International Law (1935), pp. 183 et seq.; Dicey, Conflict of Laws, 5th ed. (1932), pp. 667 et seq., and a discussion in note 22, p. 958, especially at pp. 964, 965; per Evatt J. in Barcelo's Case[27]; Vita Food Products Inc. v. Unus Shipping Co. Ltd.[28].
