October 18, 1787 - James Madison wrote to George Washington, N. York:
"Since the Revolution every State has made great inroads & with great propriety in many instances on this monarchical code.[Edit: Englands "Common Law"] The "revisal of the laws" by a Committe of wch. Col. Mason [Edit: George Mason] was a member, though not an acting one, abounds with such innovations. The abolition of the right of primogeniture, which I am sure Col. Mason does not disapprove, falls under this head.. What could the Convention have done? If they had in general terms declared the Common law to be in force, they would have broken in upon the legal Code of every State in the most material points: they wd. have done more, they would have brought over from G.B. a thousand heterogeneous & anti-republican doctrines, and even the ecclesiastical Hierarchy itself, for that is a part of the Common law."
June 18, 1788 - George Mason, In Convention, Richmond (Debates in the Several State Conventions on the Adoption of the Federal Constitution), states:
"We have it in our power to secure our liberties and happiness on the most unshaken, firm, and permanent basis. We can establish what government we please. But by that paper we are consolidating the United States into one great government, and trusting to constructive security. You will find no such thing in the English government. The common law of England is not the common law of these states."
So why did Virginia pass a law adopting Enlgish common law? It’s right there in front of you in black.and white. It is still on the books.
