35-8A-12. Waiver of rights void--Mutually binding agreements or voluntary dispute settlements not prohibited. Any waiver of the rights or remedies granted by this chapter is void. However, nothing in this chapter limits or prohibits suppliers and wholesalers from entering into mutually binding written agreements as defined in this chapter or to limit or prohibit good faith dispute settlements voluntarily entered into by the parties. However, no provision of any written agreement may purport to require the law of any state other than South Dakota to govern the relationship of the parties or to require wholesalers to waive the right to have disputes with their suppliers resolved in courts of competent jurisdiction in South Dakota or to require a wholesaler to waive the right to trial by jury in South Dakota.
