A constitution is framed for ages to come, and is designed to approach immortality as nearly as human institutions can approach it.
A law repugnant to the constitution is void….
Judicial power is never exercised for the purpose of giving effect to the will of the judge; always for the purpose of giving effect to the will of the legislature; or, in other words, to the will of the law.
Should Congress...pass laws for the accomplishment of objects not entrusted to the Government, it would become the painful duty of [the Supreme Court] to...say that such an act was not the law of the land.
The people made the Constitution, and the people can unmake it. It is the creature of their own will, and lives only by their will.
