The wiggle room for the Supreme Court and Federal Courts should also be removed so definitely and strictly that the Constitution answers it all, including the instructions for them to butt out and keep their mouths shut.
How are you going to write a constitution that covers every possible case - it would be infinitely long and hence require an infinitely long time to write (and read) it?
So long as it's a finite document, it will need
someone with the authority to interpret it, to apply it to the specifics, and to fill in the gaps.
