588. The court may at any time, on the application of a party, revise or annul the authorization judgment if it considers that conditions relating to the issues of law or fact or to the composition of the class are no longer satisfied.
If the court revises the authorization judgment, it may allow the representative plaintiff to amend the conclusions sought. In addition, if circumstances so require, the court may, even on its own initiative, modify or divide the class at any time.
If the court annuls the authorization judgment, the proceeding continues between the parties before the competent court according to the procedure set out in Book II.
