The legislative and executive branch cannot legislate or administrate contrary to the Constitution - not without amending the Constitution itself. the Constitution is the supreme law of the land. The Supreme Court cannot overrule the plain meaning if the Constitution - and contrary to what you may assert, the Constitution was written in pretty plain language IOT to make it accessible to citizens without necessity of a law degree. Case law is merely the effort to obfuscate the obvious in a mire of complex language.
