The Ihlen Declaration was a statement made on 22 July 1919 by the Norwegian Foreign Minister Nils Claus Ihlen on the topic of Denmark's sovereignty over Greenland. Ihlen declared verbally to the Danish minister that "the plans of the Royal [Danish] Government respecting Danish sovereignty over the whole of Greenland... would be met with no difficulties on the part of Norway". The declaration became an issue when the question was raised whether the statement was binding on Norway. The question eventually went all the way to the Permanent Court of International Justice in the form of the Eastern Greenland Case in 1933.[1][2]
