The coordination motion judge must set a hearing date on a petition for coordination within 30 days of the date of the order assigning the coordination motion judge.

The petitioner must provide notice of the hearing to each party appearing in an included action. If the coordination motion judge determines that a party that should be served with notice of the petition for coordination has not been served with notice, the coordination motion judge must order the petitioner to promptly serve that party.
