 of this kind can be preserved in practice no other way than through the medium of the courts of justice; whose duty it must be to declare all acts contrary to the manifest tenor of the constitution void. Without this, all the reservations of particular rights or privileges would amount to nothing.

Some perplexity respecting the right of the courts to pronounce legislative acts void, because contrary to the constitution, has arisen from an imagination that the doctrine would imply a superiority of the judiciary to the legislative power. It is urged that the authority which can declare the acts of another void, must necessarily be superior to the one whose acts may be declared void. As this doctrine is of great importance in all the American constitutions, a brief discussion of the grounds on which it rests cannot be unacceptable.

There is no position which depends on clearer principles, than that every act of a delegated authority, contrary to the tenor of the commission under which it is exercised, is void. No legislative act, therefore, contrary to the constitution, can be valid. To deny this, would be to affirm, that the deputy is greater than his principal; that the servant is above his master; that the representatives of the people are superior to the people themselves; that men, acting by virtue of powers, may do not only what their powers do not authorize, but what they forbid.

If it be said that the legislative body are themselves the constitutional judges of their own powers, and that the construction they put upon them is conclusive upon the other departments, it may be answered, that this cannot be the natural presumption, where it is not to be recollected from any particular provisions in the constitution. It is not otherwise to be supposed, that the constitution could intend to enable the representatives of the people to substitute their will to that of their constituents. It is far more rational to suppose, that the courts were designed to be an intermediate body between the people and the legislature, in order, among other things, to keep the latter within the limits assigned to their authority.
