Under which clause is the federal government given primacy over state laws when conflicts arise (federal preemption)?

• A. Elastic Clause
• B. Commerce Clause
• C. Due Process Clause
• D. Supremacy Clause

Answer: (D)

The essential idea is that federal law takes priority over state law when they clash. This is guaranteed by the Supremacy Clause, which says the Constitution, federal laws, and treaties are the supreme law of the land and bind judges in every state. When a federal statute conflicts with a state law, or when federal regulation occupies the field, the state law is preempted. The Elastic Clause can justify creating federal laws, but it doesn’t establish that federal law always wins in conflicts. The Commerce Clause enables federal regulation of trade, which can lead to preemption in some cases, but supremacy itself comes from the Supremacy Clause. The Due Process Clause protects individuals’ rights, not the hierarchy of laws between states and the federal government.
