(2)Nothing in this section shall restrict the power of a Provincial Legislature to make any law which under this Act it has power to make, but if any provision of a Provincial law is repugnant to any provision of a Federal law which the Federal Legislature has under this section power to make, the Federal law, whether passed before or after the Provincial law, shall prevail, and the Provincial law shall to the extent of the repugnancy, but so long only as the Federal law continues to have effect, be void.
