Article 591. On application by the applicant or the defendant, the President may exceptionally decide, on the basis of the facts before him and after hearing the other party, that a case is to be determined pursuant to an expedited procedure derogating from the provisions of these Rules, where the particular urgency of the case requires the Court shall give its ruling with the minimum of delay. 2. An application for a case to be decided under an expedited procedure shall be made by a separate document lodged at the same time as the application initiating the proceedings or the defense, as the case may be. 3. Under the expedited procedure, the originating application and the defense may be supplemented by a reply and a rejoinder only if the President considers this to be necessary. 4. An intervener may lodge a statement in intervention only if the President considers this to be necessary. 5. Once the defense has been lodged or, if the decision to adjudicate under an Expedited procedure is not made until after that pleading has been lodged, once that decision has been taken, the President shall fix a date for the hearing, which shall be communicated forthwith to the parties. 6. He may postpone the date of the hearing where the organization of measures of inquiry or of other preparatory measures so requires. 7. Without prejudice to rules, the parties may supplement their arguments and offer further evidence in the course of the oral procedure. They must, however, give reasons for the delay in offering such further evidence. 8. The Court shall give its ruling after hearing the parties.
