Parchment barriers insufficient

Will it be sufficient to mark, with precision, the boundaries of these departments in the constitution of the government, and to trust to these parchment barriers against the encroaching spirit of power? . . . But experience assures us that the efficacy of the provision has been greatly overrated; and that some more adequate defense is indispensably necessary for the more feeble against the more powerful members of the government. The legislative department is everywhere extending the sphere of its activity and drawing all power into its impetuous vortex.  Madison, Number 48

a mere demarcation on parchment of the constitutional limits of the several departments is not a sufficient guard against those encroachments which lead to a tyrannical concentration of all the powers of government in the same hands. Madison, Number 48
