The Declaration of Independence has no force of law and no enforcement mechanism. The Constitution’s Supremacy Clause says that it is the constituion that is “the supreme law of the land.”
Article Six: “This Constitution, and the Laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land;” [excerpt]
I dunno, it seems that it had a pretty good enforcement method. It beat England. Apparently it had some divine force of law behind it.
The Constitutions Supremacy Clause says that it is the constituion that is the supreme law of the land.
The Declaration proves otherwise. When it was put forth, British Law also declared itself "the supreme law of the land", but when the dust settled, everyone saw that it wasn't.
Let's face it, if what the Declaration says is true; that it's power derives from "Laws of Nature and of Nature's God" then what are the puny laws of man next to that?
I think the two things are on a collision course and I expect we shall see which is stronger in our lifetimes.
