What is the purpose of preemption in federal law?

• A. To expand state authority over areas delegated to the federal government.
• B. To resolve conflicts between federal and state law by establishing the supremacy of federal law.
• C. To allow states to override federal statutes when convenient.
• D. To require courts to ignore federal statutes in areas of state concern.

Answer: (B)

Preemption means federal law can override state law when they conflict, based on the Supremacy Clause. Its purpose is to resolve incompatible laws by establishing the supremacy of federal regulation, ensuring nationwide consistency in areas the federal government regulates and preventing states from undermining federal objectives. Preemption can occur in several ways: express preemption when a statute explicitly says federal law replaces state law, field preemption when the federal regulatory scheme is so comprehensive it occupies the entire field, and conflict preemption when it’s impossible to comply with both or when state law presents an obstacle to federal goals.

So, it’s not about expanding state authority, letting states override federal statutes, or requiring courts to ignore federal statutes in state matters. It’s about ensuring federal law stands as the supreme law when there’s a conflict.
