Presidential Unilateral Actions: Constitutional and Political Checks

Throughout history, presidents have invoked a broad array of powers. Some are legitimate and well grounded; others exceed constitutional boundaries and have met defeat in Congress, the courts, and the public. Still others originate from historical errors by the Supreme Court, particularly in the field of external affairs. The powers analyzed in this article begin with these: enumerated, implied, inherent, prerogative, ministerial, and discretionary. Presidential instruments of power include executive orders and proclamations. The erroneous “sole organ” doctrine, first appearing in the Curtiss-Wright case of 1936, was at issue in the Jerusalem passport case of Zivotofsky v. Kerry. The scope of unilateral executive authority is being tested in initiatives by the Obama administration in the field of immigration policy.
