The National President represents the Commonwealth in matters of international law. He concludes in the name of the Commonwealth, alliances and other treaties with foreign powers. He accredits and receives ambassadors. War is declared and peace concluded by national law. Alliances and treaties with foreign States, relating to subjects within the jurisdiction of the Commonwealth, require the consent of the National Assembly.

ARTICLE 48 If any State does not perform the duties imposed upon it by the Constitution or by national laws, the National President may hold it to the performance thereof by force of arms. If public safety and order in the German Commonwealth is materially disturbed or endangered, the National President may take the necessary measures to restore public safety and order, and, if necessary, to intervene by force of arms.
