A constitution defines and limits the powers of the government it creates. It therefore follows, as a natural and also a logical result, that the governmental exercise of any power not authorized by the constitution is an assumed power, and therefore illegal.
Thomas PaineIt is not because a part of the government is elective, that makes it less a despotism, if the persons so elected, possess afterwards, as a parliament, unlimited powers. Election, in this case, becomes separated from representation, and the candidates are candidates for despotism.
Thomas PaineThere never did, there never will, and there never can exist a parliament, or any description of men, or any generation of men, in any country, possessed of the right or the power of binding and controlling posterity to the 'end of time,' or of commanding for ever how the world shall be governed, or who shall govern it. Every age and generation must be as free to act for itself, in all cases, as the ages and generations which preceded it.
