Limitação de Poderes e Limitação de Funções

Thus far, we have been speaking in general terms of the limited state or the limits to the state. It must now be made clear that such expression cover two diferent aspects of the problem, which are not always properly distinguished: the limits (a) of the powers, and (b) of the functions of the state. [...] Liberalims refers us to limits both in the power and in the functions of the state.
