Article 60 The judgment is final and without appeal. In the event of dispute as to the meaning or scope of the judgment, the Court shall construe it upon the request of any party. Article 61 1. An application for revision of a judgment may be made only when it is based upon the discovery of some fact of such a nature as to be a decisive factor, which fact was, when the judgment was given, unknown to the Court and also to the party claiming revision, always provided that such ignorance was not due to negligence. 2. The proceedings for revision shall be opened by a judgment of the Court expressly recording the existence of the new fact, recognizing that it has such a character as to lay the case open to revision, and declaring the application admissible on this ground. 3. The Court may require previous compliance with the terms of the judgment before it admits proceedings in revision. 4. The application for revision must be made at latest within six months of the discovery of the new fact. 5. No application for revision may be made after the lapse of ten years from the date of the judgment. Article 62 l. Should a state consider that it has an interest of a legal nature which may be affected by the decision in the case, it may submit a request to the Court to be permitted to intervene. 2 It shall be for the Court to decide upon this request.
