128. (1) The Federal Court shall, to the exclusion of any other court, have jurisdiction to determine in accordance with any rules of court regulating the exercise of such jurisdiction— (a) any question whether a law made by Parliament or by the Legislature of a State is invalid on the ground that it makes provision with respect to a matter with respect to which Parliament or, as the case may be, the Legislature of the State has no power to make laws; and (b) disputes on any other question between States or between the Federation and any State. (2) Without prejudice to any appellate jurisdiction of the Federal Court, where in any proceedings before another court a question arises as to the effect of any provision of this Constitution, the Federal Court shall have jurisdiction (subject to any rules of court regulating the exercise of that jurisdiction) to determine the question and remit the case to the other court to be disposed of in accordance with the determination. (3) The jurisdiction of the Federal Court to determine appeals from the Court of Appeal, a High Court or a judge thereof shall be such as may be provided by federal law.
