(a) In all actions or proceedings brought pursuant to Sections 21167, 21168, and 21168.5, including the hearing of an action or proceeding on appeal from a decision of a lower court, all courts in which the action or proceeding is pending shall give the action or proceeding preference over all other civil actions, in the matter of setting the action or proceeding for hearing or trial, and in hearing or trying the action or proceeding, so that the action or proceeding shall be quickly heard and determined. The court shall regulate the briefing schedule so that, to the extent feasible, the court shall commence hearings on an appeal within one year of the date of the filing of the appeal.
(b) To ensure that actions or proceedings brought pursuant to Sections 21167, 21168, and 21168.5 may be quickly heard and determined in the lower courts, the superior courts in all counties with a population of more than 200,000 shall designate one or more judges to develop expertise in this division and related land use and environmental laws, so that those judges will be available to hear, and quickly resolve, actions or proceedings brought pursuant to Sections 21167, 21168, and 21168.5.
(c) In an action or proceeding filed pursuant to this chapter that is joined with any other cause of action, the court, upon a motion by any party, may grant severance of the actions. In determining whether to grant severance, the court shall consider such matters as judicial economy, administrative economy, and prejudice to any party.
