Which institution is the final arbiter on whether or not a legislative act -- national, state or local -- is constitutional? Which institution is the final arbiter on what any constitutional provision means?

"Which institution is the final arbiter on what any constitutional provision means?"

Justice Marshall:
the people have an original right to establish, for their future govern-ment, such principles as, in their opinion, shall most conduce to their own happiness, is the basis on which the whole American fabric has been erected. The exercise of this original right is a very great exertion; nor can it, nor ought it, to be frequently repeated. The principles, therefore, so established, are deemed fundamental. And as the authority from which they proceed is supreme, and can seldom act, they are designed to be permanent."

IE - The people have established that their right to bear arms shall not be infringed.
-- No 'institution' is authorised to 'arbite', - judge, - that such a fundamental inalienable right can be prohibited or amended.

Why do you advocate that these institutions have such powers to abridge your own liberty? It violates self interest & common sense.
