Discretion Quotes - page 2
What all this amounts to, then, is that the Rule of Law requires that administrative discretion in coercive action (i.e., in interfering with the person and property of the private citizen) must always be subject to review by an independent court which is not an instrument of, or even privy to, the aims of current governmental policy; that its review must in all such instances extend to the substance of the administrative act and not merely to the question whether it was infra or ultra vires; and that, if such a court finds that the rights of private citizens have been infringed, it will assess damages just as if the right of this person had been violated by another private citizen. This, in addition to the familiar requirements of generality, equality, and certainty of the law is really the crux of the matter, the decisive point on which it depends whether the Rule of Law prevails or not.
