“ This is what they call "consulting the Senate," and the judgment of the majority is a senatus consultum (decree of the Senate) . This conclusion is only advisory as the Senate has no power to make laws; but Rome obeys this advice as if it were a law. The people have confidence in the senators, knowing that they have more experience than themselves; the magistrates do not dare to resist an assembly composed of nobles who are their peers. And so the Senate regulates all public business: it declares war and determines the number of the armies ”
