The Comitia Tributa were properly the council of the Roman people. They were convoked by the tribunes alone; at them the tribunes were elected and passed their plebiscita. The senate not only had no standing in them, but even no right to be present; and the senators, being forced to obey laws on which they could not vote, were in this respect less free than the meanest citizens. This injustice was altogether ill-conceived, and was alone enough to invalidate the decrees of a body to which all its members were not admitted. Had all the patricians attended the comitia by virtue of the right they had as citizens, they would not, as mere private individuals, have had any considerable influence on a vote reckoned by counting heads, where the meanest proletarian was as good as the princeps senatus .
