Whereas the treaties of the United States, in any war in which the United States is a neutral, impose on the United States certain obligations to both neutral and belligerent nations; And Whereas the treaties of the United States, in any war in which the United States is a neutral, require that the United States exert all the vigilance within their power to carry out their obligations as a neutral; And Whereas treaties of the United States require that the Panama Canal shall be free and open, on terms of entire equality, to the vessels of commerce and of war of all nations observing the rules laid down in Article 3 of the so-called Hay-Pauncefote treaty concluded between the United States and Great Britain, November 18, 1901; Now, Therefore , by virtue of the authority vested in me by section 5 of the Panama Canal Act, approved August 24, 1912 (ch. 390, sec. 5, 37 Stat. 562), as amended by the act of July 5, 1932 (ch. 425, 47 Stat. 578), I hereby prescribe the following regulations governing the passage and control of vessels through the Panama Canal or any part thereof, including the locks and approaches thereto, in any war in which the United States is a neutral; 1. Whenever considered necessary, in the opinion of the Governor of the Panama Canal, to prevent damage or injury to vessels or to prevent damage or injury to the Canal or its appurtenances, or to secure the observance of the rules, regulations, rights, or obligations of the United States, the Canal authorities may at any time, as a condition precedent to transit of the Canal, inspect any vessel, belligerent or neutral, other than a public vessel, including its crew and cargo, and, for and during the passage through the Canal, place armed guards thereon, and take full possession and control of such vessel and remove therefrom the officers and crew thereof and all other persons not specially authorized by the Canal authorities to go or remain on board thereof during such passage. 2. A public vessel of a belligerent or neutral nation shall be permitted to pass through the Canal only after her commanding officer has given written assurance to the authorities of the Panama Canal that the rules, regulations, and treaties of the United States will be faithfully observed.

Constitutional & Societal Entities Impacted
Policy Areas & Topics
The Framers' Constitutional Council
1787 PrismEvaluating this order against the constitutional debates of 1787 and the limits of Article II executive power.
"When the President acts in absence of either a congressional grant or denial of authority, he can only rely upon his own independent powers, but there is a zone of twilight in which he and Congress may have concurrent authority."
James Madison
Separation of Powers & Legislative Primacy
"Power is of an encroaching nature, and it ought to be effectually restrained from passing the limits assigned to it." — Federalist No. 48 (1788)
Madison would view this order with watchful scrutiny. Operating in the 'Zone of Twilight' where Congress is silent, each such directive establishes an administrative precedent that steadily expands the executive perimeter at the expense of legislative primacy.
Alexander Hamilton
The Energetic Executive & Unified Command
"The direction of war implies the direction of the common strength; and the power of directing and employing the common strength must be under the direction of the single hand of the Executive." — Federalist No. 74 (1788)
Hamilton would forcefully champion executive discretion here. For foreign entanglements, commerce defense, and national security, deliberative assemblies are too slow and faction-ridden. A unified, energetic Executive exercising swift command is precisely what the Philadelphia Convention intended for national preservation.
George Mason
Bill of Rights, Due Process & 10th Amendment
"The president will be surrounded by flatterers and sycophants... and the great powers of the executive will gradually absorb the liberties of the people." — Cato IV (Anti-Federalist, 1787)
The Anti-Federalist prism advises continuous democratic vigilance. Even routine administrative directives aggregate centralized federal power away from town halls and state assemblies toward a distant executive apparatus.

Federalism & State Sovereignty
Engages state and local partners in cooperative federalism programs.
Due Process & Individual Rights
Applies regulatory or compliance standards to private contractors or commercial entities.
Youngstown Jacksonian Tier
The order relies on inherent Article II executive discretion, civil service management, or foreign diplomacy where Congress has neither expressly approved nor prohibited action.
This order operates within Justice Jackson’s Zone of Twilight, resting upon concurrent presidential authority or congressional silence.
