The federal courts' powers of judicial review have been established for over 200 years since Marbury v Madison. The inferior courts are also organised pursuant to the constitution and have full judicial powers (though can be abolished or rearranged by Congress should they decide):

> The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. (Start of Art. 3).

It is good to not GAF about down votes, but do consider the possibility it is because you are confidently incorrect, not because the voters are ill-informed or angry.
