1925 was an exceedingly busy year for the court, which sat for 210 days, with four extraordinary sessions as well as the ordinary session, producing 3 judgments and 4 advisory opinions. The first judgment was given in the Exchange of Greek and Turkish Populations Case, the second (by the Court of Summary Procedure) was on the interpretation of the Interpretation of the Treaty of Neuilly Case, and the third in the Mavrommatis Palestine Concessions Case. The 4 advisory opinions issued by the Court were in the Polish Postal Service in Danzig Question, the Expulsion of the Ecumenical Patriarch Question, the Treaty of Lausanne Question and the German Interests in Polish Upper Silesia Question. 1926 saw reduced business, with only one ordinary session and one extraordinary session; it was, however, the first year that all 11 judges had been present to hear cases. The court heard two cases, providing one judgment and one advisory opinion; a second question on German Interests in Polish Upper Silesia, this time a judgment rather than an advisory opinion, and an advisory opinion on the International Labour Organization.
