The History of Rome. Book II

The tribunes of the multitude (tribuni plebis

) arose out of the military tribunes and derived from them their name; but constitutionally they had no further relation to them. On the contrary, in respect of powers the tribunes of the plebs stood on a level with the consuls. The appeal from the consul to the tribune, and the tribune's right of intercession in opposition to the consul, were, as has been already said, precisely of the same nature with the appeal from consul to consul and the intercession of the one consul in opposition to the other; and both cases were simply applications of the general principle of law that, where two equal authorities differ, the veto prevails over the command.  Moreover the original number (which indeed was soon augmented), and the annual duration of the magistracy, which in the case of the tribunes changed its occupants on the 10th of December, were common to the tribunes and the consuls. They shared also the peculiar collegiate arrangement, which placed the full powers of the office in the hands of each individual consul and of each individual tribune, and, when collisions occurred within the college, did not count the votes, but gave the Nay precedence over the Yea; for which reason, when a tribune forbade, the veto of the individual was sufficient notwithstanding the opposition of his colleagues, while on the other hand, when he brought an accusation, he could be thwarted by any one of those colleagues.  Both consuls and tribunes had full and co-ordinate criminal jurisdiction, although the former exercised it indirectly, and the latter directly; as the two quaestors were attached to the former, the two aediles were associated with the latter[7]

. The consuls were necessarily patricians, the tribunes necessarily plebeians.  The former had the ampler power, the latter the more unlimited, for the consul submitted to the prohibition and the judgment of the tribunes, but the tribune did not submit himself to the consul. Thus the tribunician power was a copy of the consular; but it was none the less a contrast to it.  The power of the consuls was essentially positive, that of the tribunes essentially negative. The consuls alone were magistrates of the Roman people, not the tribunes; for the former were elected by the whole burgesses, the latter only by the plebeian association. In token of this the consul appeared in public with the apparel and retinue pertaining to state-officials; the tribunes sat on a stool instead of the "chariot seat," and lacked the official attendants, the purple border, and generally all the insignia of magistracy: even in the senate the tribune had neither presidency nor so much as a seat. Thus in this remarkable institution absolute prohibition was in the most stern and abrupt fashion opposed to absolute command; the quarrel was settled by legally recognizing and regulating the discord between rich and poor.
