The association aims to promote and maintain fair and free competition in the Swiss payment transactions market, particularly in the market for payment instrument acceptance, in the interest of its members. To achieve this purpose, the association takes all necessary measures in the interest of its members to ensure fair and free competition in the Swiss payment transactions market and in the market for payment instrument acceptance. The association is free to choose the means, with official and judicial steps taking precedence. This includes, in particular, the following measures based on the Swiss Cartel Act: (1) interventions with the Competition Commission (WEKO) in the interest of the members; (2) assertion of claims for elimination and cessation of competition restrictions in the interest of the members; (3) enforcement of monetary claims assigned to the association by its members, resulting from unlawful competition restrictions; (4) judicial assertion of damages claims resulting from unlawful competition restrictions, assigned to the association by its members for collective enforcement, including representation in settlement negotiations and collection of awarded amounts; (5) advising and supporting members in their independent enforcement of monetary claims resulting from unlawful competition restrictions, as well as in the judicial assertion of damages claims resulting from unlawful competition restrictions. The assignment of damages claims and other monetary claims of the members requires a written commitment and disposal agreement. Members remain free to assert their claims independently, unless an explicit assignment to the association has been made.
