Quick Summary

The edictum perpetuum was a permanent edict in Roman law that, by the time of Emperor Hadrian, had become a fixed code that only the emperor could alter. This marked a significant shift in legal authority, as magistrates no longer modified existing law through their interpretations.1

The emperor's legislative power grew considerably, with enactments known as constitutiones principum. These included edicts (proclamations), mandates (instructions), rescripts (written answers to legal questions), and decreta (judicial decisions). By the 2nd century AD, legal textbooks stated that the emperor's commands were legally binding, and emperors increasingly legislated directly through these various forms. This development paved the way for the later dominate period, where the emperor's authority was even more absolute.21
