Article 66

The Registrar shall forthwith give notice of the request for an advisory opinion to all states entitled to appear before the Court.

The Registrar shall also, by means of a special and direct communication, notify any state entitled to appear before the Court or international organization considered by the Court, or, should it not be sitting, by the President, as likely to be able to furnish information on the question, that the Court will be prepared to receive, within a time limit to be fixed by the President, written statements, or to hear, at a public sitting to be held for the purpose, oral statements relating to the question.

Should any such state entitled to appear before the Court have failed to receive the special communication referred to in paragraph 2 of this Article, such state may express a desire to submit a written statement or to be heard; and the Court will decide.

States and organizations having presented written or oral statements or both shall be permitted to comment on the statements made by other states or organizations in the form, to the extent, and within the time limits which the Court, or, should it not be sitting, the President, shall decide in each particular case. Accordingly, the Registrar shall in due time communicate any such written statements to states and organizations having submitted similar statements.
