For questions about the fundamental charter of the United States, and the several states of the U.S..
“The [U.S.] Constitution is a charter or grant of powers conferred upon the [U.S.] Federal Government by the people of the United States. The Constitution is the life of the Government of the United States" (De Lima v. Bidwell, 182 U.S. 1, 31 (1901)) as the United States is entirely a creature of the Constitution which is the source of all of its power and authority. Reid v. Covert, 354 U.S. 1, 5-6 (1956)
Therefore, the "Constitution […] of the United States [is] the supreme Law of the Land; and the Judges in every State [are] bound thereby, any thing in the Constitution or Laws of any State to the Contrary notwithstanding". (Cl. 2., Art. VI, U.S. Const.)
