“ But the senate had acquired a far more effective control over the popular vote through the observance of certain unwritten rules regulating the relation between senate and magistrates. It was generally understood that the magistrate should not question the people on any important matter without the senate’s consent, nor refuse to do so at its request; that one magistrate should not employ his veto to quash the act of another except at the senate’s bidding, nor refuse to do so when directed. ”
