The fed 'law' can be changed, and will be, -- if States ignore it as an unconstitutional infringement of due process. -- Congress has no delegated power to prohibit.
The issue was recently at the top court regarding the Feds and it was upheld. I think John Roberts wrote the majority view.
So what? -- Do you think the 'top courts' opinion is infallible?
-- Try reading Marbury, and you will see that the Constitutions words, as written, -- are the supreme law.. -- Court opinions are often reversed.
I think it means the issue won't be revisited for a good part of a decade.
