Two Forms of Government
The Roman style of law is Executive Law that is voted upon by representatives and encoded by the Executive power into statutes. In other words Legislative Law is a set of rules created by a group of people, interpreted by Magistrates, to regulate "entities" or corporate forms, i.e. not common people.
On the other hand, at the time of the signing of the U.S. Constitution, our legal process was an extension of the old English Common Law. The Common Law was developed by the ancient Israelites and started with the Ten Commandments, continuing through the Magna Carta, and concluding with the Bill of Rights in the U.S. Constitution.
