We have BOTH admiralty law and common law court procedures.
If a citizen violates a code, statute, ordinance... crimes without a victim, it is addressed under Admiralty Law. These are contract violations.
If ANYBODY, citizen or People, harms another - there is a corpus dilicti, a body of a crime - corpse, burnt home, etc, then this is addressed under Common Law.
Do we have British Common Law, or American constitutional law?
