"The propensity of the legislative department to intrude upon the rights, and to absorb the powers, of the other departments, has been already suggested and repeated; the insufficiency of a mere parchment delineation of the boundaries of each, has also been remarked upon; and the necessity of furnishing each with constitutional arms for its own defense, has been inferred and proved. From these clear and indubitable principles results the propriety of a negative, either absolute or qualified, in the Executive, upon the acts of the legislative branches."
