Under the British North America Act, 1867, and the amending statutes, there is "one Parliament for Canada" (sect. 17), while each province has its Legislature. Each provincial Legislature is empowered exclusively to make laws in relation to certain specified subjects (including property and civil rights and the administration of justice), and also in relation to "all matters of a merely local or private nature in the province"; while the Dominion Parliament may "make laws for the peace, order, and good government of Canada in relation to all matters not coming within" the classes of subjects assigned exclusively to the provincial Legislatures. The division of functions has given rise to much confusion and litigation; but, speaking generally, the trend of judicial decision has been towards a wide interpretation of the provincial powers. The "residuary powers" are in the Dominion Parliament. The constitution of the Commonwealth of Australia, as defined by the Commonwealth of Australia Constitution Act, 1900, is of a different character. The Federal Parliament is entrusted with power to make laws with respect to a number of subjects divided into no less than 39 classes (sect. 51); the State Legislatures have concurrent powers of legislation, but in case of conflict the law of the Commonwealth is to prevail over the State law (sect. 109). The "residuary powers" are in this case left to the States. There is power to alter the Constitution with the consent of a majority of the electors in a majority of the States and of a majority of the electors of the Commonwealth (sect. 123)--a power which has been freely used.
