The law of nature is that which she has taught all animals; a law not peculiar to the human race, but shared by all living creatures, whether denizens of the air, the dry land, or the sea. Hence comes the union of male and female, which we call marriage; hence the procreation and rearing of children, for this is a law by the knowledge of which we see even the lower animals are distinguished.
The civil law of Rome, and the law of all nations, differ from each other thus. The laws of every people governed by statutes and customs are partly peculiar to itself, partly common to all mankind. Those rules which a state enacts for its own members are peculiar to itself, and are called civil law: those rules prescribed by natural reason for all men are observed by all people alike, and are called the law of nations. Thus the laws of the Roman people are partly peculiar to itself, partly common to all nations; a distinction of which we shall take notice as occasion offers….
Our law is partly written, partly unwritten, as among the Greeks. The written law consists of statutes, plebiscites, senatusconsults, enactments of the Emperors, edicts of the magistrates, and answers of those learned in the law. A statute is an enactment of the Roman people, which it used to make on the motion of a senatorial magistrate, as for instance a consul. A plebiscite is an enactment of the commonalty, such as was made on the motion of one of their own magistrates, as a tribune….
A senatusconsult is a command and ordinance of the senate, for when the Roman people had been so increased that it was difficult to assemble it together for the purpose of enacting statutes, it seemed right that the senate should be consulted instead of the people. Again, what the Emperor determines has the force of a statute, the people having conferred on him all their authority and power by the lex regia, which was passed concerning his office and authority. Consequently, whatever the Emperor settles by rescript, or decides in his judicial capacity, or ordains edicts, is clearly a statute: and these are what are called constitutions.
Codex Justinianus:
Protection of Freewomen Married to Servile Husbands, c. 530 [Vll.24.i.]
Unions between freewomen and adscripticii, previously discouraged by the Romans by depressing the status of the freewoman, were no longer to result in loss of freedom after Justinian’s new law.
