It appears that in Civil law, stemming from Roman law, the terms are used define (i) laws governing the activities of the state and the interaction between the state and the individual or private entity vs. laws governing the activities of individuals/private entities and their interaction with each other.
MM: That sounds _very similar_ to my statement that public law is legislation/court precedent, private law is contract. “Laws governing the activities of the state and the interaction between the state and the individual or private entity” sounds a lot like legislation and government regulation to me; “laws governing the activities of individuals/private entities and their interaction with each other” sounds a lot like contract.
