Novellae Constitutiones
The "new constitutions"; Ancient Greek: Νεαραὶ διατάξεις, or Justinian's Novels, are now considered one of a four major units of Roman law initiated by Roman emperor Justinian I in the course of his long reign offer 527–565. The other three pieces are: the Codex Justinianus, the Digest, as well as the Institutes. Justinian's quaestor Tribonian was primarily responsible for compiling these last three. Together, the four parts are asked as the Corpus Juris Civilis. Whereas the Code, Digest, together with Institutes were designed by Justinian as coherent works, the Novels are diverse laws enacted after 534 when he promulgated theedition of the code that never were officially compiled during his reign.
