A difference of opinion of more than usual interest has recently developed with regard to the composition of the International Commission of the Danube. The question at issue turns upon the interpretation of certain articles of the Treaty of Versailles in the light of the important constitutional changes which have occurred within Germany since 1919. Under the Treaty of Versailles, the International Commission was to include “two representatives of German riparian States,” in addition to representatives of the other riparian and certain non-riparian States. Since the signature of the Treaty, there has been a gradual redistribution of powers within Germany, culminating in 1934 when the sovereign powers of the German states were transferred to the Reich. When the German representatives at the session of the International Commission in December, 1934, presented full powers issued in the name of the Reich alone, their eligibility was challenged, and they were allowed to take their seats only under a modus vivendi pending settlement of the issue. At the request of the British and French Governments, in which other States represented on the International Commission subsequently joined, the dispute was referred to the League of Nations Advisory and Technical Committee for Communications and Transit.
