The Grand Duchy is also deneutralized and Germany binds herself to "accept in advance all international arrangements which may be concluded by the Allied and Associated Powers relating to the Grand Duchy" (Art. 40).

The third alternative of the maintenance of the union with Germany was not left open to the electorate.
