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. - John Marshall

The government of the Union, then, … is, emphatically, and truly, a government of the people. In form and in substance it emanates from them. Its powers are granted by them, and are to be exercised directly on them, and for their benefit.

I am N!ai. When the white people first came, I was already a young woman with breasts. Before the white people came, we did what our hearts wanted. We lived in different places, far apart, and when our hearts wanted to travel, we traveled. We were not poor; we had everything we could carry. No one told us what to do.
Now the white people tell us to stay in this place. There are too many people. There’s no food to gather. Game is far away, and people are dying of tuberculosis.
But when I was a little girl, we left sickness behind us when we moved.

[T]he constitution controls any legislative act repugnant to it. . . . It is emphatically the province and duty of the judicial department to say what the law is. . . . So if a law be in opposition to the constitution; if both the law and the constitution apply to a particular case, so that the court must either decide that case conformably to the law, disregarding the constitution; or conformably to the constitution disregarding the law; the court must determine which of these conflicting rules governs the case. This is the very essence of judicial duty. . . . Those then who controvert the principle that the constitution is to be considered, in court, as a paramount law, are reduced to the necessity of maintaining that courts must close their eyes on the constitution, and see only the law. This doctrine would subvert the very foundation of all written constitutions . . . It would be giving the legislature a practical and real omnipotence . . . The judicial power of the United States is extended to all cases arising under the constitution.
