Supreme Court is
1) not superior to the Constitution which is the Supreme Law of the Land over the feds (US Const., Art IV, Cl. 2) and
2) not constitutionally authorized to make nation law which is reserved exclusively to Congress (Id., Art. I, Sec. 1).
An unconstitutional Court decision is constitutionally null and void.
Cool, thanks for the little side trip down civics 101.
