38 AEGEAN SEA (JUDGMENT) 91. In examining the application of the General Act to the present dispute, the Court has not overlooked a suggestion that the Act has never been applicable as between Turkey and Greece by reason of the existence of the Greco-Turkish Treaty of Friendship, Neutrality, Conciliation and Arbitration signed at Ankara on 30 October 1930 (League of Nations, Treaty Series, Vol. 125, No. 2841). This Treaty provided for a general system of procedures for thepacific settlement of disputes between the two countries sirnilar to, but in some respects different from, those provided in the General Act. It entered into force by exchange of ratifications on 5 October 1931, and under Article 28 was expressed to continue in force for successive periods of five years, unless denounced. The length of these periods was extended to ten years by an "Additional Treaty" of 27 April 1938, which at the same time provided that "the mutual engagements, bilateral or plurilateral", which the parties had contracted should "continue to produce their full effect irrespective of the provisions of the present Treaty" (League of Nations, Treaty Series, Vol. 193, No. 4493). By these Treaties and by the General Act, therefore, Greece and Turkey appear, prima facie, to have provided for two parallel systems of pacific settlement, for so long as the 1930 Treaty and the General Act might continue in force, and both Greece and Turkey have stated that they consider the 1930 Treaty still to be in force. 92. Consequently, if the question of the effect of the 1930 Treaty on the applicability of the General Act as between Greece and Turkey had called for decision in the present proceedings, the Court would have been confronted with the problem of the CO-existenceof different instruments establishing methods of peaceful settlement, a question discussed in the Electricity Company of Sofia and Bulgaria case (P.C.I.J., Series A/B, No. 77). In that event it might also have been necessary to examine the relation between the obligations of the two States under the 1930 and 1938 Treaties and those under the General Act in the light of the pertinent provisions of those instruments-a point whch was the subject of a question put by two Members of the Court during the hearings. 93. However, the fact already established by the Court that, by reason of Turkey's invocation of reservation (6) to the Greek accession, the General Act is not applicable to the present dispute, and the fact that the 1930 Treaty has not been invoked as a basis for the Court's jurisdiction in the present proceedings, dispense the Court from any 'need to enter into these questions. 94. In paragraph 32 (2) of the Application the Greek Government specified as the second basis on which it claims to establish the Court's j urisdiction:
