Each of the fourteen Provinces of the Republic has its own Constitution, which cannot be in conflict with the Federal Constitution which provides a necessarily limited degree of autonomy in the government of the Provinces. The Federal Constitution prohibits the State Government from usurping such functions of the Federal Government as entering into treaties with foreign Powers, enacting laws affecting interstate or foreign commerce, navigation, citizenship, naturalization, the coining of money, or the establishment of custom houses.

These restricted autonomous powers were wisely provided to prevent the conflict of laws which is of frequent occurrence under other Federal systems. The protection of the moral and material interests of foreign residents of the Republic, or of foreigners having interests therein, is scrupulously enforced by the Courts according to the Constitution where such questions are involved; and frequent decisions have been given by the Federal Tribunals in that direction in order to maintain the inviolability of the Constitution which was framed in the interest of the Argentine nation and of "all the people of the world who may reside in Argentine territory."
