These remained in place until the office was abolished in 367/366 BC and the consulship was reintroduced. Consuls had extensive powers in peacetime (administrative, legislative and judicial), and in wartime often held the highest military command. Additional religious duties included certain rites which, as a sign of their formal importance, could only be carried out by the highest state officials. Consuls also read auguries, an essential step before leading armies into the field. Two consuls were elected each year, serving together, each with veto power over the other's actions, a normal principle for magistracies. It is thought that originally only patricians were eligible for the consulship. Consuls were elected by the Comitia Centuriata, which had an aristocratic bias in its voting structure which only increased over the years from its foundation. However, they formally assumed powers only after the ratification of their election in the older Comitia Curiata, which granted the consuls their imperium by enacting a law, the "lex curiata de imperio". If a consul died during his term (not uncommon when consuls were in the forefront of battle) or was removed from office, another would be elected by the Comitia Centuriata to serve the remainder of the term as "consul suffectus" ("suffect consul"). A consul elected to start the yearcalled a "consul ordinarius" ("ordinary consul")held more prestige than a suffect consul, partly because the year would be named for ordinary consuls (see consular dating). According to tradition, the consulship was initially reserved for patricians and only in 367 BC did plebeians win the right to stand for this supreme office, when the Lex Licinia Sextia provided that at least one consul each year should be plebeian. The first plebeian consul, Lucius Sextius, was elected the following year. Nevertheless, the office remained largely in the hands of a few families as, according to Gelzer, only fifteen "novi homines" - "new men" with no consular background - were elected to the consulship until the election of Cicero in 63 BC. Modern historians have questioned the traditional account of plebeian emancipation during the early Republic (see Conflict of the Orders), noting for instance that about thirty percent of the consuls prior to Sextius had plebeian, not patrician, names. It is possible that only the chronology has been distorted, but it seems that one of the first consuls, Lucius Junius Brutus, came from a plebeian family.
