What happens to a case that falls under both state and federal law?

Answer 1

The Constitution of the United States is based on the principles of Federalism, in which the federal and state governments share power over the well-being of its citizens. Because sharing can get a bit messy when it comes to politics, it is important to understand that most of the time the Federal laws supersede the state laws or statutes. In a case, where a case falls under both state and federal law, most of the time the Federal law will supersede the state law. Often times, states may have the ability to alter a federal law to fit their state purposes like in the case of marijuana legalization and statewide gerrymandering, but for the most part constitutional laws would supersede state mandates.
