[1] Medullinus was elected military tribune with consular power in 432 BC with two others: Lucius Pinarius Mamercinus and Spurius Postumius Albus Regillensis.
Nevertheless, social tensions remained a concern and the plebs regretted that no plebeian had been elected as a consular tribune so even that the institution of that new judiciary must have responded in kind.
[a 3][4] In 420 BC, Medullinus was elected consular tribune for the third time, once again with Lucius Quinctius Cincinnatus and Aulus Sempronius Aratinus, and with a new colleague, Marcus Manlius Vulso, all patricians.
[a 4][5] The tribunes reproached Sempronius with the errors committed during the war against the Volsci at the time of his consulship and made him pay amends with a fine of 15,000 asses.
[a 4] It is during the third tribunal of Lucius Furius that Medullinus held the trial of the Vestal Postumia, suspected of deviant behavior, but who was finally acquitted.
