The full text of Article 12 of the Treaty between the Allied and Associated Powers and Poland is the following: “Poland agrees that the stipulations in the foregoing Articles, so far as they affect persons belonging to racial, religious or linguistic minorities, constitute obligations of international concern and shall be placed under the guarantee of the League of Nations. They shall not be modified without the assent of the majority of the Council of the League of Nations. The United States, the British Empire, France, Italy and Japan hereby agree not to withhold their assent from any modification in these Articles which is in due form assented to by a majority of the Council of the League of Nations. “Poland agrees that any member of the Council of the League of Nations shall have the right to bring to the attention of the Council any infraction of the Council, or any danger of infraction of any of these obligations, and that the Council may thereupon take such action as it may deem effective in the circumstances.
“Poland further agrees that any difference of opinion as to questions of law or fact arising out of these Articles between the Polish Government and any one of the Principal Allied and Associated Powers, or any other power, a member of the Council of the League of Nations, shall be held to be a dispute of an international character under Article 14 of the Covenant of the League of Nations. The Polish Government hereby consents that any such dispute shall, if the other party thereto demands, be referred to the Permanent Court of International Justice. The decision of the Permanent Court shall be final and shall have the same force and effect as an award under Article 13 of the Covenant.”
