Question

How is the Supreme Court of Washington different than the national Supreme Court?

Answer 1

D. The Supreme Court of Washington is the final appeals court in the state(I believe)

The Supreme Court's additional powers to review decisions of the National Court (when an appeal is not available) and to consider references on constitutional issues, are given by the Constitution itself. Procedure in those cases is governed by Rules made by the Judges of the Supreme Court. (Hope this helps.)
