A pending civil case is related to another pending civil case, or to a civil case that was dismissed with or without prejudice, or to a civil case that was disposed of by judgment, if the cases:
Whenever a party in a civil action knows or learns that the action or proceeding pending, dismissed, or disposed of by judgment is related to another action or proceeding pending in any state or federal court in California, the party must serve and file a Notice of Related Case.
The Notice of Related Case must:
The Notice of Related Case must be filed in all pending cases listed in the notice and must be served on all parties in those cases.
The Notice of Related Case must be served and filed as soon as possible, but no later than 15 days after the facts concerning the existence of related cases become known.
The duty under (b)-(e) is a continuing duty that applies when a party files a case with knowledge of a related action or proceeding, and applies thereafter whenever a party learns of a related action or proceeding.
Within 5 days after service upon on a party of a Notice of Related Case, the party may serve and file a response supporting or opposing the notice. The response must state why one or more of the cases listed in the notice are not related or why other good cause exists for the court not to transfer the cases to or from a particular court or department. The response must be filed in all pending cases listed in the notice and must be served on all parties in those cases.
If all the related cases have been filed in one superior court, the court, on notice to all parties, may order that the cases, including probate and family law cases, be related and may assign them to a single judge or department. In a superior court where there is a master calendar, the presiding judge may order the cases related. In a court in which cases are assigned to a single judge or department, cases may be ordered related as follows:
(Subd (h) amended effective January 1, 2008; adopted as subd (d) effective January 1, 1996; previously amended and relettered as subd (e) effective January 1, 2007.)
The court, department, or judge issuing an order relating cases under this rule must either:
If for any reason a case is not ordered related under this rule, that case will remain assigned to the court, judge, or department where it was pending at the time of the filing and service of the Notice of Related Case.
A party is not required to serve and file Notice of Related Case under this rule if another party has already filed a notice and served all parties under this rule on the same case.
