Amhatielos Case: On May 19, 1953, the Court, by a vote of 10 to 4 decided that the United Kingdom was “under an obligation to co-operate with Greece in constituting a Commission of Arbitration, in accordance with the Protocol of 1886, as provided in the Declaration of 1926”. After reviewing the submissions of the two parties, and recalling that the Court had previously held that it had no jurisdiction to decide of the merits of the Ambatielos claim, the Court stated that the question at issue was whether the United Kingdom government was under an obligation to accept arbitration of the difference between that government and Greece concerning the validity of the claim presented by Greece “in so far as this claim is based on the Treaty of 1886”. The majority of the Court felt that, for the purpose of determining the obligation of the United Kingdom, the words “claims … based on the provisions of the … Treaty of 1886” could not be understood as meaning claims actually supportable under that Treaty. The Court believed that these words could only mean “claims depending for support on the provisions of the Treaty of 1886, so that the claims will eventually stand or fall according as the provisions of the Treaty are construed one way or another”. In its argument, the Greek government had invoked Articles I, X, XII and XV of the Treaty of 1886 and, relying on the most-favored-nation clause in Article X therein, invoked Article 16 of a treaty of peace and commerce between the United Kingdom and Denmark signed in 1661 as well as additional treaties between the United Kingdom and third states. The Hellenic government argued that these provisions supported their claim that the Ambatielos claim for denial of justice in British courts was based on the provisions of the 1886 treaty. The Court agreed that the difference between the parties was “the kind of difference which, according to the Declaration of 1926, should be submitted to arbitration”.
