When Augustus reached office, his power and duty included being one of the two consuls, which allowed him to sit in the Senate, oversee the law courts, and introduce legislation to the Centuriate Assembly. In 23 BCE, the Senate gave Augustus several powers of a tribune, granting him the ability to veto actions taken by government officials and introduce laws to the Plebian Assembly.
