On May 9 he vetoed, at the request of Servilius Isauricus, honors proposed for Munatius Plancus in Gaul (Cic. Fam. 10.12.3-4; cf. 10.21.3). In August when Octavian was elected Consul he carried a bill to expel his colleague Servilius Casca from office (see above), and on November 27 he carried the law which established the Second Triumvirate (App. BC 4.7; Dio 47.2.1-2; cf. Fast. Colot., Degrassi 273-275, 502). See above, Triumviri Rei Publicae Constituendae. (Broughton MRR II)
Tr. pl. 43. See MRR 2.340, and correct May 9 to April 9. Refer also to Cic. Ad Brut. 2.2. Shackleton Bailey would identify the Titius of Fam. 10.21.3 with L. Titius, brother-in-law of Plancus and father of the consul of 31 (CLF 2.563). See also Bengtson, ANRW 1.1, 1972, 967-981.
