There should be Competition between the courts of the various states. Actors would follow scripts. There would be evidence provided by an independent agency. The court would win that could best determine facts & truth and dispense justice that was fair and impartial. The laws, rules and precedents of each state would be followed. The UN could adjudicate wins and losses. Each state could prepare one hypothetical case. The case to be heard, would be chosen at random. It would be an elimination tournament. When a court loses, it’s out!
The reasons for a verdict would have to be correct. If the verdict was correct, but the key evidence or logic was missed, then the court would get low marks.
I saw actors play out such a trial in Salem, MA. It was a reenactment of a witch trial. The jury (the audience) was instructed to find that the woman was a witch if she talked in “tongues”. There were a couple of similar criteria. It was proven that the woman did meet the required criteria for being a witch. I voted against the guilty verdict because I thought the death penalty was too severe. My audience found the woman innocent of witchcraft by one vote! Half the time the audience found the woman guilty of witchcraft and the judge ordered her hung. (I wonder if they would have reenacted the hanging had I voted differently)
Although the verdict of my audience was correct, the reasons were wrong. I voted the woman innocent of witchcraft simply because I didn’t think the woman deserved to be hung as a witch. In my case the court would have lost because the verdict should have been guilty but for the mores of a few “jurists” that chose not to follow the judge’s instructions.
My estimate, from the facts of my life, is that the courts are playing at the Pop Warner level. Remember that the laws of the state are also fundamental for justice.
