be manifested through the medium of the courts of justice. The government of the Union, like that of each State, must be able to address itself immediately to the hopes and fears of individuals; and to attract to its support those passions which have the strongest influence upon the human heart. It must, in short, possess all the means, and have aright to resort to all the methods, of executing the powers with which it is intrusted, that are possessed and exercised by the government of the particular States.
To this reasoning it may perhaps be objected, that if any State should be disaffected to the authority of the Union, it could at any time obstruct the execution of its laws, and bring the matter to the same issue of force, with the necessity of which the opposite scheme is reproached.
The plausibility of this objection will vanish the moment we advert to the essential difference between a mere NON-COMPLIANCE and a DIRECT and ACTIVE RESISTANCE. If the interposition of the State legislatures be necessary to give effect to a measure of the Union, they have only NOT TO ACT, or TO ACT EVASIVELY, and the measure is defeated. This neglect of duty may be disguised under affected but unsubstantial provisions, so as not to appear, and of course not to excite any alarm in the people for the safety of the Constitution. The State leaders may even make a merit of their surreptitious invasions of it on the ground of some temporary convenience, exemption, or advantage.
But if the execution of the laws of the national government should not require the intervention of the State legislatures, if they were to pass into immediate operation upon the citizens themselves, the particular governments could not interrupt their progress without an open and violent exertion of an unconstitutional power. No omissions nor evasions would answer the end. They would be obliged to act, and in such a manner as would leave no doubt that they had encroached on the national rights. An experiment of this nature would always be hazardous
