UJI 13-115. Two or more plaintiffs. (Optional as preliminary instruction.)

Although there is more than one plaintiff in this action, it does not follow from that fact alone that if one is entitled to recover, another is entitled to recover. The rights of the various plaintiffs in this lawsuit are separate and distinct, and you should decide the issues as if each plaintiff had brought a separate lawsuit. [In this connection, you will note that some of the instructions apply to one plaintiff, while other instructions apply to all plaintiffs.]
