5. These included the opinion in the Minority Schools in Albania case (PCIJ [1935], Series A/B No. 64), in which the Court pointed out that the main purpose of the protection of minorities established under the League System, i.e. the preservation of the distinguishing characteristics of the minorities, warranted the application of a substantial, as opposed to a merely formal, concept of equality. For a list of the different advisory opinions by the PCIJ relating to various aspects of minority protection under the League System see Capotorti, note 2, 24 footnote 43.
