Swiss Civil Procedure Code

¹If an ac­tion is dir­ec­ted against two or more de­fend­ants, the court that has jur­is­dic­tion with re­gard to one de­fend­ant has jur­is­dic­tion with re­gard to all de­fend­ants un­less jur­is­dic­tion is based solely on an agree­ment on jur­is­dic­tion.

²If two or more ac­tions that are fac­tu­al con­nec­ted are raised against one and the same de­fend­ant, each court that has jur­is­dic­tion over any one of the ac­tions has jur­is­dic­tion over all of them.
