asked the Secretary of State for Foreign Affairs in what cases have applications been made to the Council of the League of Nations to fill vacancies on mixed arbitral tribunals constituted under the treaties of peace, such vacancies having been caused by the withdrawal of representatives by their respective Governments; and what has been the result of such applications?
The only cases of which I am aware in which the Council of the League was requested to appoint substitute members to mixed arbitral tribunals already working occurred in 1923. I must refer my hon. Friend to pages 242, 399, 555 and 629 of the League of Nations Journal for that year for the only official and available information on the subject.
The functions and competence of the mixed arbitral tribunals set up under the treaties of peace are defined by the treaties themselves. The jurisdiction of the tribunals is confined to certain classes of claims by nationals of the contracting parties, and does not extend to disputes between the States themselves. There can be no question of referring to the tribunals disputes other than those which fall within their jurisdiction as defined by the treaties which established them.
