(Denny Crane: "Sometimes you can only look for answers from God and failing that... and Fox News".)
I'll give an example: The Supreme Court declared the line-item veto unconstitutional because it gave extra-Constitutional legislative power to the executive. The only Constitutional way to make such a law would be through an Amendment.
But when the courts decide to declare something unconstitutional based on foreign law or their own personal whims - which has happened all too often recently - it is prudent for Congress to use their Constitutional power of impeaching these rogue judges.
