When an agency finds that justice so requires, it may postpone the
effective date of action taken by it, pending judicial review. On such
conditions as may be required and to the extent necessary to prevent
irreparable injury, the reviewing court, including the court to which a case
may be taken on appeal from or on application for certiorari or other writ to
a reviewing court, may issue all necessary and appropriate process to
postpone the effective date of an agency action or to preserve status or
rights pending conclusion of the review proceedings.
