The learned Solicitor-Generals for the States of New South Wales, Victoria and South Australia, in their arguments in support of the view that there was no inconsistency, sought to find indications in the Commonwealth Act of a recognition that State laws on the subject should remain effective and that the Commonwealth Act should be supplementary to or cumulative upon the State law. The first of the sections of the Commonwealth Act which was said to indicate that that statute did not intend to cover the whole field of racial discrimination was s. 9, which refers to racial discrimination in "any other field of public life," and which, it was said, left some areas of private life untouched, and available for regulation by State law. The words of s. 9(1) which refer to human rights and fundamental freedoms in (inter alia) any field of public life have a very wide scope, as is shown by s. 9(2) and Art. 5, and include rights which exist in the field of private life, such as the right to marriage and choice of spouse (Art. 5(d)(iv)). If the word "public" in s. 9 is intended to limit the extent to which the Commonwealth Act interferes with the private lives and affairs of individuals, that does not mean that the field of racial discrimination has not been covered, but rather that it has been covered in a way that recognizes that there are some limits to the extent to which the law should intrude upon personal privacy. The next section to which reference was made was s. 10(1), which overrides State laws under which persons of one race do not enjoy, or do not enjoy fully, rights which are enjoyed by persons of another race, and to s. 10(3), which makes specific provision in relation to laws dealing with Aboriginals and Torres Strait Islanders. It was submitted that it was significant that s. 10 did not specifically exclude the operation of State laws which themselves proscribe acts of racial discrimination, particularly since at the time when the Commonwealth Act was enacted there was in force in one State a law of that kind, namely the Prohibition of Discrimination Act 1966 SA. The provisions of s. 10 were no doubt inserted in an endeavour to comply with the requirements of Art. 2(1)(c) of the Convention, which imposed upon the parties to the Convention an obligation inter alia "to amend, rescind or nullify any laws and regulations which have the effect of creating or perpetuating racial discrimination wherever it exists." In any case the presence of s. 10, which undoes the effect of laws which themselves lead to discrimination, does not provide any indication that it was intended by the Parliament to leave the field open to State laws which prohibit racial discrimination and provide remedies for those persons who were discriminated against. Another provision on which reliance was placed was s. 21(2)(c)(iii), under which the Commissioner may decide not to continue with an inquiry when there is some other remedy that is reasonably available to the complainant. It is obvious enough that in some cases a person who complains of an act of racial discrimination may have a remedy in contract or in tort or under the provisions of a statute which validly deals with the act in question in some aspect other than its discriminatory quality. The fact that the Commissioner is given power to discontinue his inquiry where another remedy is available does not indicate that the Parliament contemplated that State law might validly enact remedies for persons affected by acts o racial discrimination as such. Finally, reference was made to s. 44(1) of the Commonwealth Act, which invests the several courts of the States with federal jurisdiction within certain limits and to s. 44(2) which provides that no proceedings under the act shall be instituted in a court of a State before a day to be fixed by proclamation but which concludes: "but nothing in this sub-section prevents a court from exercising jurisdiction in a matter arising under this Act in a proceeding instituted in that court otherwise than under this Act." Difficulties have in the past arisen, and indeed still arise, in determining when a matter arises under a law of the Commonwealth and the obvious purpose of the relevant words of s. 44(2) is to avoid the inconvenience that would arise if a State court, in the course of exercising jurisdiction in a matter which did not arise under the Commonwealth Act (e.g. in an action for tort or contract), was faced with the argument that the act which gave rise to the cause of action was an act of racial discrimination and that the matter accordingly arose under the Act. The section has nothing to say on the subject whether a State may provide remedies of its own for racial discrimination.
