The Confederate Constitution also mandated a supreme court. How did that work out? It basically prohibited the Confederate government from interfering with slavery but that didn't stop Davis from sending emissaries to Europe promising an end to slavery in exchange for recognition. The Confederate constitution was not something the Confederate government had much respect for.
You make no sense. The Supreme Court is NOT the constitution, and constitutions can be amended:
"ARTICLE V, Section I. (I) Upon the demand of any three States, legally assembled in their several conventions, the Congress shall summon a convention of all the States, to take into consideration such amendments to the Constitution as the said States shall concur in suggesting at the time when the said demand is made; and should any of the proposed amendments to the Constitution be agreed on by the said convention, voting by States, and the same be ratified by the Legislatures of two- thirds of the several States, or by conventions in two-thirds thereof, as the one or the other mode of ratification may be proposed by the general convention, they shall thenceforward form a part of this Constitution. But no State shall, without its consent, be deprived of its equal representation in the Senate." ["Constitution of the Confederate States." Avalon Project, March 11, 1861]
