The year 1930 has been marked by the eighteenth (ordinary) session of the Permanent Court of International Justice, which began on June 16,1930, and continued until August 26, 1930, and by the nineteenth (extraordinary) session, which began on October 22, 1930, and ended on December 6, 1930; by the rendering of Advisory Opinion No. 17, on the question of the Greco-Bulgarian “ Communities” ; by the rendering of Advisory Opinion No. 18, on the question relating to the Free City of Danzig and the International Labor Organization; and by the rendering of an important order in the Franco-Swiss Zones case. During this year, also, Judge Frank B. Kellogg was elected to fill the vacancy caused by the resignation of Charles Evans Hughes, i.e., to serve from September 17, 1930, to December 31, 1930; and nineteen members of the Court were elected for the new term of nine years, beginning on January 1, 1931. The Protocol for the Revision of the Statute of the Court failed to come into force, as anticipated, on September 1, 1930, and the court continues, at any rate for the time being, under the unamended statute.
