Law of Citations (Roman concept)

In Valentinian's Law of Citations he is classed with Papinian, Paulus, Gaius and Ulpian, as one of the five jurists whose recorded views were considered decisive.

Under Theodosus II's Law of Citations, the writings of Papinian, Paulus, Ulpian, Modestinus, and Gaius were made the primary juristic authorities who could be cited in court.

According to the legal historian Alan Watson, "This Law of Citations marks a low point of Roman jurisprudence, since [it declares] the correct opinion is to be found by counting heads, not by choosing the best solution."

In their original context, the statements of the law contained in these fragments were just private opinions of legal scholars - although some juristic writings had been privileged by Theodosius II's Law of Citations in 426.

After his death, however, his writings were recognized as of great authority, and the emperor Theodosius II named him in the Law of Citations, along with Papinian, Ulpian, Modestinus and Paulus, as one of the five jurists whose opinions were to be followed by judicial officers in deciding cases.
