50 U.S.C. § 23 — Jurisdiction of United States courts and judges

This law gives federal courts and judges power to handle complaints against alien enemies after the President makes the proclamation described in section 21 of this title. After such a proclamation, every court of the United States with criminal jurisdiction, and every justice and judge of the courts of the United States, is authorized, and it is their duty, upon a complaint against an alien enemy resident and at large within their jurisdiction or district — who is a danger to the public peace or safety, and contrary to the tenor or intent of the proclamation or other established regulations — to have such alien duly apprehended and brought before the court, judge, or justice. After a full examination and hearing on the complaint, if sufficient cause appears, the court may order the alien to be removed out of the territory of the United States, or to give sureties for good behavior, or to be otherwise restrained, in keeping with the proclamation or regulations established. The court may also imprison or otherwise secure the alien until the order made is carried out.
