To make a division of power effectual, a veto in one form or another is indispensable. The right of each to judge for itself of the extent of the power allotted to its share, and to protect itself in its exercise, is what, in reality, is meant by a division of power.

How can this full, perfect, just and supreme voice of the people, embodied in the Constitution, be brought to bear, habitually and steadily, in counteracting the fatal tendency of the government to the absolute and despotic control of the numerical majority?

A difference must be made between a decision against the constitutionality of a law of Congress and of a State. The former acts as a restriction on the powers of this government, but the latter as an enlargement.

John C. Calhoun Quotes
