The opinion which was rendered on such an occasion was called senatus consultum. Inst. 1, 2, 5; Clef des Lois Rom. h. t.; Merl. Repert. h. t. These decrees frequently derived their titles from the names of the consuls or magistrates who proposed them; as, senatus-consultum Claudianum, Libonianum, Velleianum, &c. from Claudius, Libonius, Valleius. Ail. Pand. 30.
