California Codes, Code of Civil Procedure - CCP, Part 2 — Of Civil Actions, Title 6 — Of the Pleadings in Civil Actions, Chapter 2 — Pleadings Demanding Relief, Article 4 — Cross-Complaints, Section 428.30
Where a person files a cross-complaint as authorized by Section 428.10, he may unite with the cause of action asserted in the cross-complaint any other causes of action he has against any of the cross-defendants, other than the plaintiff in an eminent domain proceeding, whether or not such cross-defendant is already a party to the action.
Notes
Allows a person filing an authorized cross-complaint to combine the asserted cause of action with any other causes of action the person has against any cross-defendant, whether or not already a party. Exempts the plaintiff in an eminent-domain proceeding from being targeted by those additional combined causes of action.
