*009] THE LIMITS OF EXECUTIVE POWER 263,
Case. It applies historical and structural methodologies to answer
those unexamined questions, assessing important consequences to
several current theories and cases concerning presidential power.
Part I of this Article lays the groundwork for a theory of
presidential power that is founded upon the structural allocations of
power in Articles I and II of the Constitution and the historical
reasons for those allocations. The construction of the presidency
owes much less to political theory or to a reflexive reaction to George
Ill than to two centuries of historical experiences in Great Britain
and America that shaped the Framers’ views on executive and
legislative powers. A detailed historical analysis of the royal
prerogatives and how they were used to establish dominance over
Parliament is necessary to understand how and why the allocations of
power in Articles I and II constitute a massive transfer of previously
held executive power to the legislative branch.
Part II examines prevailing theories of constitutional executive
power using the historical background and its underlying principles
to show the weaknesses of those theories and to support an alternate,
more plausible general theory of presidential power. First, in lieu of
creative but ultimately inconclusive arguments over indefinite powers
that are said to be “executive” in nature, implied powers should be
tied to the powers expressly vested in the President by Article II.
Thus, the implied powers of the President are few in number, but
important. The power to enforce the laws is necessarily implied from
the President’s duty to take care that the laws should be faithfully
executed. A presidential power over foreign affairs can be implied
from the enumerated powers to make treaties and to receive and
appoint ambassadors and other public ministers. The President has
broad discretion in choosing how to exercise these implied powers.
Second, these implied powers are not plenary in nature. They are
subject to three basic limitations: (1) the President may not, without
congressional authorization, use these powers to change domestic law
or to create or alter existing legal obligations; (2) these powers are
subject to regulation by Congress; and (3) in the event of a conflict
between the exercise of these powers and congressional legislation,
the latter prevails.
Each of these principles follows from the historical limits of
prerogative power, the decision to make express presidential powers
subject to legislative constraint, and the fundamental theorem that
Article II powers cannot be greater than the prerogatives legally
exercised by the King.
