Well technically constitution is the highest law of land. So any law that doesn't alain with current constitution is invalid . If it comes to point, you can fight for it and what ever is in constitution will win. Meaning your constuational right are there and no one can take it off unless they change constitution.

But practically it's pain in as* to deal with neplease legal and governmental systems. And long manures in Supreme Court gonna take and how they going to define constitution is other story.
