a legal technician, he often consulted a jurist about the technical aspects of the case, but he was not bound by the jurist's reply. At the end of the litigation, if things were not clear to him, he could refuse to give a judgment, by swearing that it wasn't clear. Also, there was a maximum time to issue a judgment, which depended on some technical issues (type of action, etc.). Later on, with the bureaucratization, this procedure disappeared, and was substituted by the so-called "extra ordinem" procedure, also known as cognitory. The whole case was reviewed before a magistrate, in a single phase. The magistrate had obligation to judge and to issue a decision, and the decision could be appealed to a higher magistrate. Legacy In the East When the centre of the Empire was moved to the Greek East in the 4th century, many legal concepts of Greek origin appeared in the official Roman legislation. The influence is visible even in the law of persons or of the family, which is traditionally the part of the law that changes least. For example, Constantine started putting restrictions on the ancient Roman concept of patria potestas, the power held by the male head of a family over his descendants, by acknowledging that persons in potestate, the descendants, could have proprietary rights. He was apparently making concessions to the much stricter concept of paternal authority under Greek-Hellenistic law. The Codex Theodosianus (438 AD) was a codification of Constantian laws. Later emperors went even further, until Justinian finally decreed that a child in potestate became owner of everything it acquired, except when it acquired something from its father. The codes of Justinian, particularly the Corpus Juris Civilis (529–534) continued to be the basis of legal practice in the Empire throughout its so-called Byzantine history. Leo III the Isaurian issued a new code, the Ecloga, in the early 8th century. In the 9th century, the emperors Basil I and Leo VI the Wise commissioned a combined translation of the Code and the Digest, parts of Justinian's codes, into Greek, which became known as the Basilica. Roman law as preserved in the codes of Justinian and in the Basilica remained the basis of legal practice in Greece and in the courts of the Eastern Orthodox Church even after the fall of the Byzantine Empire and the conquest by the Turks, and, along with the Syro-Roman
