Without capacity to give authorizations of that sort, we should have the anomaly of a legislative power which in many circumstances calling for its exertion would be but a futility." [Per Hughes C.J. in Panama Refining Co. Ryan(3)] "This is not to say that the three branches are not co ordinate parts of one government and that each in the field of its duties may not invoke the action of the two other branches in so far as the action invoked shall not be an assumption of the constitutional field of action of another branch." [Per Taft C.J. in J.W. Hampton Jr. & Co. vs U. S.(4)] I have quoted these extracts at the risk of encumbering my opinion for 2 reasons:firstly, because they (1) (3) ; (2) (4) ; 815 show that notwithstanding the prevalence of the doctrine of separation of powers in America, the rule against delega tion of legislative power is by no means an inelastic one in that country, and many eminent Judges there have tried to give a practical trend to it so as to bring it in line with the needs of the present day administration, and secondly, because they show that the rule against delegation is not a necessary corollary from the doctrine of separation of powers.
