A single case can require courts to apply both state and federal law

Evidence

It might seem logical therefore for state courts to decide cases involving state law and federal courts cases involving federal law. In actuality, however, the rules governing the jurisdiction of U.S. courts—that is, the types of cases a federal court is authorized to decide—are not that simple. For one thing, a single case might involve more than one body of law. Gideon, for example, was convicted of violating a Florida criminal statute in a court established by the constitution and laws of Florida. However, he claimed that the U.S. Constitution guaranteed him the right to an attorney. Thus, the Florida courts in Gideon’s case had to consider both state law (the criminal statute) and federal law (the constitutional rights guaranteed to defendants in state court). — G.
