Full Text of Rule 3.523
Plain-English Summary
Filing the notice of submission in each court under rule 3.522 is only half the job. Rule 3.523 requires the petitioner to also serve that same notice, along with the petition for coordination and its supporting documents, on every party appearing in every included action, so that no party learns about a pending coordination request affecting its case only by chance.
The rule carries the same five-court-day deadline that runs through this article: the petitioner must submit the notice to the Chair of the Judicial Council within five court days of submitting the petition, tying the filing obligation under rule 3.522, the service obligation here, and the proof-of-filing and proof-of-service requirement under rule 3.521(b) into a single short window after the petition goes in.
