DoorDash Inc. has asked a Delaware judge to dismiss a proposed class action that accuses the on-demand food-delivery service of improperly collecting sales tax in states that don’t allow it, claiming that the dispute should be hashed out privately in arbitration.

Attorneys for the San Francisco-based DoorDash argued in a court filing late last week that customers who sign up to use DoorDash agree to the company’s terms and conditions, which mandate binding individual arbitration for disputes and a waiver of the right to participate in class actions.
