But there is. You may not like that the Court is Constitutionally given the necessary power to interpret the Constitution -- but they have been -- and therefore their decisions are the law of the land, unless challenged by the legistlative, executive, and citizens of the US -- primarily by Constitutional amendment.
Procedure was properly followed -- at least to the point that no amendment seems to be arising from the other branches.
If you accept the Constitution, you have to accept the procedures it lays out for its interpretation and enforcement.
The Constitution doesn't lay out any procedures for interpretation. SCOTUS erred quite egregiously, and we have every right to shout that fact from the rooftops, without in any way diminishing our fidelity to the Constitution.
