"All laws which are repugnant to the Constitution are null and void."
- Marbury v. Madison, 5 U.S. 137, 176
"Men by their constitutions are naturally divided into two parties: 1. Those who fear and distrust the people, and wish to draw all powers from them into the hands of the higher classes. 2. Those who identify themselves with the people, have confidence in them, cherish and consider them as the most honest and safe, although not the most wise depositary of the public interests."
- Thomas Jefferson to Henry Lee, 1824. ME 16:73
