Question

Many states prohibit their lottery tickets from being sold out of the state, so Pic-A-State would have its agents buy lotter tickets in various states and hold them there; someone in Pennsylvania would buy a claim on the tickets held in the other states. Congress passed a law prohibiting interstate transmission of lottery ticket information to be used for lottery ticket sales. Pic-A-State, which was being put out of business, challenged the law as unconstitutional. Was it correct? (Pic-A-State Pa. v. Reno)
