Praetor's Edict
(重定向自Edictum perpetuum)

The Praetor's Edict (Edictum praetoris) in ancient Roman law was an annual declaration of principles made by the new Praetor urbanus – the elected magistrate charged with administering justice within the city of Rome. During the early Empire the Praetor's Edict was revised to become the Edictum perpetuum.
