Codex Justinianus (Code of Justinian)
The Codex Justinianus (Code of Justinian) is one part of the Corpus Juris Civilis, the codification of Roman law ordered by Justinian I in the early sixth century. Two other units, the Digest, and the Institutes were carried out during his reign. The fourth part, the Novellae Constitutiones (New Constitutions, or Novels), was compiled unofficially after his death but is now thought of as part of the Corpus Juris Civilis.
Shortly after Justinian became emperor in 527, he decided the empire's legal system needed repair. There existed three codices of imperial laws and other individual constitutions, many of which conflicted or were out of date. The Codex Gregorianus and the Codex Hermogenianus were unofficial compilations. (The term "Codex" refers to the physical aspect of the works, being in book form, rather than on papyrus rolls, the transition to the codex having occurred around 300 A.D.) The Codex Theodosianus was an official compilation ordered by Thodosius II. In February of 528, Justinian promulgated the C. "Hac quae necessario" in which was created a ten man commission that would review these earlier compilations as well as individual laws, eliminate everything unnecessary or obsolete, make changes as it saw fit, and create a single compilation of imperial laws in force. The commission was headed by the praetorian prefect, John of Cappadocia and also included Tribonian, who was later to head the other Corpus Juris Civilis projects.
The commission finished its work in fourteen months, and the compilation was promulgated in April of 529 by the C. "Summa." However, this compilation did not eliminate all the conflicts that had arisen over the years in Roman jurisprudence, and the constitutions in the Code were to be used alongside the conflicting opinions ancient jurists. "The citation of the said constitutions of Our Code, with the opinions of the ancient interpreters of the law, will suffice for the disposal of all cases." Justinian attempted to harmonize these conflicting opinions by issuing his "Fifty Decisions" and by passing additional new laws. This meant his Code no longer reflected the latest imperial law. Thus, Justinian ordered a new compilation to supersede the first, and this Codex was published in 534. No copies of the first edition of the Code have survived, only a fragment of an index of contents on an Egyptian papyrus remain. Known as the "Codex reptitae praelectionis," this second edition of the Code was published on November 16 and took effect on December 30 of 534. The Codex consists of twelve books: book 1 concerns ecclesiastical law, sources of law, and the duties of higher offices; books 2-8 cover private law; book 9 deals with crimes; and books 10-12 contain administrative law.
Justinian's Codex was largely lost in the West with the fall of the Western Roman Empire. The only manuscript that once contained the entire Codex is a Veronese palimpsest of the sixth or seventh century and it is now only fragments. It appears as if the Code was shortened in the Middle Ages into an "Epitome Codex," with inscriptions being dropped and numerous other changes made. Some time in the eight or ninth century, the last three books of the Code were separated out from the others, and many other laws in the first nine books, including all of those written in Greek, were dropped. Substantially complete versions of Justinian's Codex were restored around the end of the twelfth century, and the humanists of the sixteenth century added the laws originally promulgated in Greek. Paul Krüger created the modern, standard version the Codex in 1877.
 English Translations
No English translations were made of the Codex until the twentieth century. In 1932 the English translation of the entire Corpus Juris Civilis by Samuel Parsons Scott was published posthumously. Unfortunately, Scott used the Kriegel brothers' edition of the CJC rather than that of Mommsen, Krüger, Schoell and Kroll, which is accepted as the most reliable, and his translation was severely criticized. Reviewing Scott's work, the Roman law scholar W. W. Buckland, wrote that Scott "...had at his disposal an adequate latinity and has produced a version written in an English which can be read with pleasure. But much more than that was needed, and the work cannot be said to satisfy these further requirements." Around the same time that Scott was active, Wyoming Supreme Court Justice Fred H. Blume was translating the Code and Novels, using the standard Mommsen, Krüger, Schoell and Kroll version. While this was not printed in his lifetime, in 2005 his translation of both the Code and the Novels was published on Annotated Justinian Code website. A new edition of the Codex, based on Blume's, is being prepared by Professor Bruce Frier and an expert panel for publication by the Cambridge University Press in late 2013.
