It may be well to notice a case in which the very equality of application, which is, as has been said, implied in the mere idea of a law couched in general terms, is felt to be unjust. This is the case where the words of a statute either from being carelessly drawn, or on account of the inevitable defects of even the most precise terminology, include (or exclude) persons and circumstances which are clearly not included in (or excluded from) the real intent and purpose of the law. In this case a particular decision, strictly in accordance with a law which generally considered is just, may cause extreme injustice: and so the difference between actual Law and Justice is sharply brought out. Still we cannot in this way obtain principles for judging generally of the justice of laws.
