Arestaurant franchise properly sued the franchise owner of one of its restaurants in federal court for breach of contract for refusing to display materials for the new marketing campaign it launched. the court scheduled a pretrial conference for the purpose of "pressuring" the parties to settle the case. both parties were given proper notice of the scheduled hearing, but only the owner of the restaurant and her attorney appeared at the conference. the judge immediately issued an order requiring the restaurant franchise to pay the restaurant owner travel expenses and attorneys' fees for failing to attend. is this a valid order of the court?
