Road Lines is an interstate bus company operating in a five-state area. A federal statute authorizes the Interstate Commerce Commission (ICC) to permit interstate carriers to discontinue entirely any unprofitable route. Road Lines applied to the ICC for permission to drop a very unprofitable route through the sparsely populated Shaley Mountains. The ICC granted that permission even though Road Lines provided the only public transportation into the region. Foley is the owner of a mountain resort in the Shaley Mountains, whose customers usually arrived on vehicles operated by Road Lines. After exhausting all available federal administrative remedies, Foley filed suit against Road Lines in the trial court of the state in which the Shaley Mountains are located to enjoin the discontinuance by Road Lines of its service to that area. Foley alleged that the discontinuance of service by Road Lines would violate a statute of that state prohibiting common carriers of persons from abandoning service to communities having no alternate form of public transportation. The state court should 
dismiss the action, because Foley lacks standing to sue.  direct the removal of the case to federal court, because this suit involves a substantial federal question.  hear the case on its merits and decide for Foley because, on these facts, a federal agency is interfering with essential state functions.  hear the case on its merits and decide for Road Lines, because a valid federal law preempts the state statute on which Foley relies.
