Proclamation 2561—Denying Certain Enemies Access to the Courts
By the President of the United States of America
Whereas, the safety of the United States demands that all enemies who have entered upon the territory of the United States as part of an invasion or predatory incursion, or who have entered in order to commit sabotage, espionage, or other hostile or warlike acts, should be promptly tried in accordance with the Law of War;
Now, Therefore, I, Franklin D. Roosevelt, President of the United States of America and Commander in Chief of the Army and Navy of the United States, by virtue of the authority vested in me by the Constitution and the statutes of the United States do hereby proclaim that all persons who are subjects, citizens, or residents of any Nation at war with the United States or who give obedience to or act under the direction of any such Nation and who during time of war enter or attempt to enter the United States or any territory or possession thereof, through coastal or boundary defenses, and are charged with committing or attempting or preparing to commit sabotage, espionage, hostile or warlike acts, or violations of the law or war, shall be subject to the law of war and to the jurisdiction of military tribunals; and that such persons shall not be privileged to seek any remedy or maintain any proceeding, directly or indirectly, or to have any such remedy or proceeding sought on their behalf, in the courts of the United States, or of its States, territories, and possessions, except under such regulations as the Attorney General, with the approval of the Secretary of War, may from time to time prescribe.
