You do realize that much of our law is based on English Common Law, don't you? That much of the Constitution was based on English Common Law? That Justice Scalia frequently cites Common Law, and said
use British law for those elements of the Constitution that were taken from Britain. The phrase "the right to be confronted with witnesses against him" -- what did confrontation consist of in England? It had a meaning to the American colonists, all of whom were intimately familiar with my friend Blackstone. And what they understood when they ratified this Constitution was that they were affirming the rights of Englishmen. So to know what the Constitution meant at the time, you have to know what English law was at the time.
Each and every clause of our constitution is a rejection of common law.
The term “natural born citizen” is alien to common law; they had native born subjects. At the time natural born citizen was understood to mean one that was a citizen by birth regardless of where he was born because both parents were citizens.
