Re:Marbury vs. Madison (Score 3, Informative)

The actual first instance of interpretational SCOTUS opinion, or, reading into the Constitution crap that ain't there, was Scott vs. Stanford. (Ref: Justice Antonin Scalia, Woodrow Wilson International Center for Scholars, 2005-03-15) Marbury vs. Madison just cemented the Court's recognized authority of judicial review; considering whether a law is Constitutional or not.
