Illinois passes a law requiring doctors to be certified before providing medical services to a citizen of

Illinois. You represent a client who is licensed to practice medicine in Indiana. Your client recently

administered a drug to a patient in an ER of an Illinois hospital located right across the border of Indiana

and Illinois. She is fined $50,000 and refuses to pay. What constitutional arguments can you make on your

client's behalf as to why this law is unconstitutional as applied to her?
