Answer:
The Justinian Code forms part of the Corpus Juris civilis. Published on April 7, 529, the Justinian Code was drawn up under the Byzantine emperor Justinian by a commission of imperial officials and professors of law schools, chaired by the jurist Tribonien.
It comprises several laws regarding taxes, religion, private relations, crime and legal proceedings, among others. Compared to the previous rules, the Justinian Code is characterized by the fact that the emperor becomes the sole source of law: the emperor alone is invested with the right to impose the rules of law such as injunctions or commandments, this right being withdrawn from the magistrates.
