Answer to Question 1
Article VI of the Constitution provides the answer to this question. The Supremacy Clause states that the Constitution, and federal statutes and treaties, shall be the supreme law of the land. If there is a conflict between federal and state statutes, the federal law preempts the field, meaning that federal law controls the issue. The state law is void. Even in cases where there is no conflict, if Congress demonstrates that it intends to exercise exclusive control over an issue, federal law preempts. Thus, state law controls only when there is no conflicting federal law and Congress has not intended to dominate the issue. In a similar Illinois case discussed in the textbook, the Supreme Court concluded that Congress intended to regulate the issue exclusively. Federal law therefore preempted the field, and local employers were obligated to obey only the federal regulations.
Answer to Question 2
In Miller v. California, the court developed a three-part test:
whether the average person, applying contemporary community standards, would find the work taken as a whole appeals to a prurient interest.
whether the work depicts or describes, in a patently offensive way, sexual conduct specifically defined by applicable state law.
whether the work taken as a whole lacks serious literary, artistic, political, or scientific value.
If all three tests are met, the work may be considered obscene and may be prohibited.
