They knew, however, that self-government is still government, and that the authority of the Constitution and the law is still authority. They knew that a government without power is a contradiction in terms. In order that their President and their Congress might not surpass the bounds of the authority granted to them, by the Constitution which the people had made, and so infringe upon the liberties of the people, they established a third independent department of the government, with the power to interpret and declare the Constitution and the law, the inferior courts and the Supreme Court of the United States. No President, however powerful, and no majority of Congress however large, can take from an individual, no matter how humble, that freedom and those rights which are guaranteed to him by the Constitution. The Supreme Court has final authority to determine all questions arising under the Constitution and laws of the United States.
