In 471 B. C. the Plebeians succeeded in carrying the famous Publilian
Law (proposed by the tribune Publilius Volero), that the tribunes should
in future be chosen only at the (popular) Comitia Tributa, instead of in
the (patrician) Comitia Centuriata. The Comitia Tributa also received
the right of deliberating and deciding upon all matters that were open
to discussion and settlement in the Comitia Centuriata. The struggle
continued, and the commons found it a great disadvantage that there was
no written law to control the chief Patrician magistrates (the consuls)
in their dealings with the Plebeians.
