SUPERNUMERARII, Rom. civil law. From the reign of Constantine to Justinian, 
advocates were divided into two classes: viz. advocates in title, who were 
called statute, and supernumeraries. The statutis were inscribed in the 
matriculation books, and formed a part of the college of advocates in each 
jurisdiction. The supernumeraries were not attached to any bar in 
particular, and could reside where, they pleased; they took the place of 
advocates by title, as vacancies occurred in that body. Code Justin., de 
adv. div. jud. c. 3, 11, 13; Calvini Lex, ad voc.; also Statuti.
