3 Niccolini (FTP 210) lists Duronius under 97, the latest possible date. He could have entered office on December 10, 98, and carried his bill before the elections and entrance upon office of the Censors, probably about April (Mommsen, Str. 2.352). He may however have held the tribunate in any year after the previous censorship. (Broughton MRR II)
Abrogated a sumptuary law, the Lex Licinia (Gell. 2.24. 10; Macrob. 3.17.7), and was expelled from the Senate by the Censors (Val. Max. 2.9.5; cf. Cic. De Or. 2.274). See above, Censors. (Broughton MRR II)
