You’re shockingly ignorant here. Our entire legal system from top to bottom is at its foundation a common law legal system. Contracts. Torts. Court procedures. Real Property. Even our constitutional law starts with a very small set of works and then builds on that using the common law system where judges create various doctrines that then form precedents and govern other cases.
No, you're shockingly retarded here... and in other places but that's for another time.
I didn't say that our legal system didn't evolve out of common law.
I did say that we don't look to common law when our current laws are clear.
