Book IV, Chapter V: THE TRIBUNATE

The tribunate is not a constituent part of the city, and should have no share in either legislative or executive power; but this very fact makes its own power the greater: for, while it can do nothing, it can prevent anything from being done. It is more sacred and more revered, as the defender of the laws, than the prince who executes them, or than the Sovereign which ordains them. This was seen very clearly at Rome, when the proud patricians, for all their scorn of the people, were forced to bow before one of its officers, who had neither auspices nor jurisdiction.
