Perchloroethylene is an inexpensive chemical that has been used by dry cleaning businesses for years. However, scientific studies have shown that this chemical is highly toxic to the environment and it has been found in reservoirs used for drinking water. Assume a State passed a law that prohibits dry cleaning businesses in the State from using this chemical. Because alternative methods of dry cleaning are more expensive, the dry cleaning businesses have decided to challenge the law in Court, arguing that it is unconstitutional. What standard of review (legal test/method of analysis) would the Court likely apply in such a case? Briefly explain your answer.
