They can claim whatever they want but The Supreme Court, and not the legislature, is the final authority when it comes to 'interpretation of the Constitution' ... If law of the land is followed, such a bill/law that reverses SC larger bench interpretation of a constitutional clause would be instantly struck down.
The Indian Supreme Court, for example, has more than once struck down even constitutional amendments (forget about a bill/law) on the grounds that they contradicted with the basic structure of the constitution .. We are far behind ..
