Full Text of § 404.6
Plain-English Summary
Orders made under the coordination chapter can be challenged much like the venue and reclassification orders elsewhere in this title. Any party has 20 days after service of written notice of entry of the order to petition the appropriate reviewing court for a writ of mandate requiring the trial court to make the order the reviewing court finds appropriate. The superior court may extend that period once, by up to 10 additional days, for good cause shown before the original 20 days expires.
The point, as with the parallel writ procedures for venue and reclassification, is to let a party challenge a coordination-related order quickly, before the litigation moves further down whatever path that order set.
