Summary

Peter Vivian Daniel Prigg v. Pennsylvania — Concurrence

But it is said, that if the states can legislate at all upon the subject of fugitives from service, they may, under the guise of regulations for securing the master's right, enact laws which, in reality, impair or destroy them. This, like every other argument drawn from the possible abuse of power, is deemed neither fair nor logical. It is equally applicable to the exercise of power by the federal as by the state governments; and might be used in opposition to all power and all government, as it is undeniable, that there is no power and no government which is not susceptible of great abuses.

I cannot regard the third clause of the fourth article as falling either within the definition or meaning of an exclusive power. Such a power, I consider as orginally and absolutely, and at all times incompatible with partition or association; it excludes everything but itself. There is a class of powers, originally vested in the states, which, by the theory of the federal government, have been transferred to the latter; powers which the constitution of itself does not execute, and which congress may or may not enforce, either in whole or in part, according to its views of policy or necessity

It is not the mere existence of the power, but its exercise, which is incompatible with the exercise of the same powr by the states. It has been said, that congress has exercised this power; and by doing so, has extinguished the power of the states, which cannot be revived by repealing the law of congress. We do not think so. If the right of the states is not taken away by the mere grant of that power to congress, it cannot be extinguished; it can only be suspended, by enacting a general bankrupt law. The repeal of that, cannot, it is true, confer the power on the states
