Bump. From a founding father:
What is a Constitution? It is the form of government, delineated by the mighty hand of the people, in which certain first principles of fundamental laws are established. The constitution is certain and fixed; it contains the permanent will of the people, and is the supreme law of the land; it is paramount to the power of the legislature, and can be revoked or altered only by the authority that made it. The life-giving principle and the death-doing stroke must proceed from the same hand. What are legislatures? Creatures of the constitution; they owe their existence to the constitution: they derive their powers from the constitution: it is their commission; and therefore, all their acts must be conformable to it, or else they will be void. The constitution is the work or will of the people themselves, in their original, sovereign and unlimited capacity. Law is the work or will of the legislature, in their derivative and subordinate capacity. The one is the work of the creator, and the other of the creature. The constitution fixes limits to the exercise of legislative authority, and prescribes the orbit within which it must move. In short, gentlemen, the constitution is the sun of the political system, around which all legislative, executive and judicial bodies must revolve. Whatever may be the case in other countries, yet, in this, there can be no doubt, that every act of the legislature, repugnant to the constitution, is absolutely void.
Justice Paterson, Vanhorne's Lessee v. Dorrance, 2 Dall. 304 C.C.D.Pa. (1795)
It's not in the Constitution so it's immaterial to the agreements made.
