Yes, and wouldn't the denial of a defendant's Constitutional Right, and denial of arguments asserting those Rights bring into question whether or not the trial was conducted properly -- whether due process was followed? What more egregious act could a court emit than to deny a protected Right? What and whom is the U.S. Constitution protecting, then, if a state or city judge can do this?
The Constitution protects us from the abuse of our rights perpetrated by the Federal government. State Constitutions protect us from the abuse of our rights by state and local governments. If our rights are abused, and upon appeal our State Supreme Court rules incorrectly, we appeal to the U.S. Supreme Court to look at our State laws and Constitution and to correct the State Supreme Court if they ruled incorrectly or did not afford us the rights guaranteed under our State Constitution.
In cases where agents of the Federal Government, or Federal Courts have denied us our rights, then we cite the U.S. Constitution when the case appears before the Supreme Court.
That is what was intended. Of course, that isn't how it is being applied today. And that is one of the core reasons our rights are so routinely being abused. We've morphed from the intended Federal system into a National system. That surely was not the intent of the Founding Fathers.
