Cal. R. 3.504
Except as otherwise provided in the rules in this chapter, all provisions of law applicable to civil actions generally apply to an action included in a coordination proceeding.
To the extent that the rules in this chapter conflict with provisions of law applicable to civil actions generally, the rules in this chapter prevail, as provided by Code of Civil Procedure section 404.7.
If the manner of proceeding is not prescribed by chapter 3 (commencing with section 404) of title 4 of part 2 of the Code of Civil Procedure or by the rules in this chapter, or if the prescribed manner of proceeding cannot, with reasonable diligence, be followed in a particular coordination proceeding, the assigned judge may prescribe any suitable manner of proceeding that appears most consistent with those statutes and rules.
At the beginning of a coordination proceeding, the assigned judge must specify, subject to rule 3.20, any local court rules to be followed in that proceeding, and thereafter all parties must comply with those rules. Except as otherwise provided in the rules in this chapter or as directed by the assigned judge, the local rules of the court designated in the order appointing the assigned judge apply in all respects if they would otherwise apply without reference to the rules in this chapter.
