High Quality Content by WIKIPEDIA articles! The unitary executive theory is a theory of American constitutional law holding that the President controls the entire executive branch. The doctrine is based upon Article Two of the United States Constitution, which vests "the executive power" of the United States in the President. Although that general principle is widely accepted, there is disagreement about the strength and scope of the doctrine. It can be said that some favor a "strongly unitary" executive, while others favor a "weakly unitary" executive. The former group argue, for example, that Congress's power to interfere with intra-executive decision-making (such as firing executive branch officials) is limited, and that the President can control policy-making by all executive agencies within the limits set for those agencies by Congress. Still others agree that the Constitution requires a unitary executive, but believe this is a bad thing, and propose its abolition by constitutional amendment.
