Hey I need to know this FAST! What was the first law to be declared unconstitutional by the supreme court? Thanks!

Look up Marbury vs. Madison or Marbury v. Madison in a search engine. Look for a summary of the case.

The first case that the U.S. Supreme Court declared a law unconstitional using its power of Judicial Review was in Marbury v Madison decided in 1803
