“Without prejudice to the generality of his powers as to reservation of Bills our Governor shall not assent in our name to, but shall reserve for the consideration of our Governor-General any Bill or any of the clauses herein specified, i.e.'(b) any Bill which in his opinion would, if it became law so derogate from the powers of the High Court as to endanger the position that that Court is, by the Act, designed to fulfil.'”
