In 528, before he was appointed quaestor, Tribonian was named by Justinian as one of the commissioners charged with preparing the new imperial legal code, the Codex Justinianus, which subsequently was issued on April 7, 529.[6] In 530, after Tribonian had become quaestor, it was natural for Justinian to put him in charge of the next major law reform project: compiling and harmonizing the writings of classical Roman jurists. Justinian's main objects in creating this harmonized compilation of juristic writings were to shorten litigation (by clarifying the law), and to create a syllabus to be used at the law schools in Beirut (Berytus) and Constantinople.[7] During the same period, Tribonian also was charged with carrying out another aspect of Justinian's reforms in legal education and codification — creating a textbook for first-year law students by updating the Institutes of Gaius.
