Originally, only members of the League Council or a nonmember state party to the minority treaty could petition for redress.(33) Only the treaty concerning Upper Silesia concluded by Germany and Poland provided for individual petition.(34) Subsequently, however, the right of individual petition was granted to some minorities.(35) A more specific indication of collective enforcement was the, agreement between Finland and Sweden relating to the population of Aaland Islands, under which the Aaland Landsting had the right of petition.(36)
Whilst proceedings against Finland have been closed (they concerned the Aaland Islands), the Commission has launched further proceedings against the other three which may eventually lead to the imposition of penalties (article 228 of the Treaty).
