 Because the consul was the highest executive office within the Republic, they had the power to veto any action or proposal by any other magistrate, save that of the Tribune of the Plebs.After a consulship, a consul was assigned one of the more important provinces and acted as the governor in the same way that a Propraetor did, only owning Proconsular imperium.A second consulship could only be attempted after an interval of 10 years to prevent one man holding too much power.
