The citizens of the State of Indiana are in the unenviable position of residing in a state which is an economically favorable dumping ground for the refuse of the Eastern states. Besides the deposit of undesirable materials from other states into Indiana soil, the status of being a trash "receiving" state means that the space available here for the disposal of Indiana waste is diminishing due to the inflow of non-Indiana trash. In order to reduce the dumping of waste from Eastern states in Indiana, the Indiana legislature passed legislation making it more costly for out of state waste to be dumped in Indiana, than it is for wastes that are generated in our state to be dumped here. Jack Castenova sued the state of Indiana because of this legislation. What constitutional issue should be alleged by Castenova?

(A) Preemption

(B) Commerce Clause

(C) Due Process

(D) Ex Post Facto

(F) Transportation Act
