Federal Act
on Private International Law
(PILA)

For­eign au­thor­it­ies have jur­is­dic­tion:

a.

if jur­is­dic­tion de­rives from a pro­vi­sion of this Act or, in the ab­sence of such a pro­vi­sion, if the de­fend­ant was dom­i­ciled in the state in which the de­cision was rendered;

b.

if, in mat­ters in­volving an eco­nom­ic in­terest, the parties sub­mit­ted to the jur­is­dic­tion of the au­thor­ity that rendered the de­cision by means of an agree­ment val­id un­der this Act;

c.

if, in mat­ters in­volving an eco­nom­ic in­terest, the de­fend­ant pro­ceeded on the mer­its without re­ser­va­tion;

d.

if, in the case of a coun­ter­claim, the au­thor­ity that rendered the de­cision had jur­is­dic­tion to hear the main claim and if there is a fac­tu­al con­nec­tion between the claim and coun­ter­claim.
