I think the constitution already makes scotus the court of original jurisdiction when it involves a state. Appellate courts should have no jurisdiction over a state.
These libs always judge shop for a lib district court judge to issue a declaration that something someone did or some law is unconstitutional then it is appealed to the circuit court where they pick a liberal court to hear it and then it is appealed to the Supreme Court. Under my proposal only the Supreme Court would be able to hear any part of the case. The opinion of the court would only be binding on the one State and not affect the laws of any other state. Any challenge to the constitutionality of any act of congress would only be heard by the Supreme Court and no lower court could hear it. Any decision on the constitutionality of a federal law would not be binding on any state. That should pretty much end the supreme court's dabbling in these esoteric constitutional challenges. Add to that a provision that a 3/4 majority of congress could overturn any opinion of the SCOTUS and that would probably return the court to the position it should have been in in the first place
