INTERESTING: The “Law of the Land” Clause of Magna Carta, the Supremacy Clause, and Judicial Review.
Most of the scholarship on the original understanding of the Supremacy Clause focuses on the word “Supreme” or “in pursuance of.”
However, the debates around the constitutional convention with respect to the Supremacy Clause were grounded in terms of judicial review. This provision of the Constitution was seen as a means to give the judiciary a negative on state laws that violated the national laws.
Alison LaCroix, in a fascinating article on the Supremacy Clause, traces its history in 1787. The Supremacy Clause was born out of the rejection of a proposal that would give the Congress a negative on state laws passed in violation of the Constitution. Instead, they turned to the Supremacy Clause to give this power to the judiciary.
