(e)
1. (1) If a plaintiff, cross-complainant, or other party seeking affirmative relief has filed a notice of conditional settlement, the court may, upon its own motion, without stipulation from the parties or their counsel, set an order to show cause as to why the court should not dismiss the entire action without prejudice and retain jurisdiction to enforce the settlement.
