Which statement accurately describes implied preemption under federalism?

• A. Implied preemption occurs only when Congress explicitly states it
• B. Implied preemption requires mutual exclusivity and Congress's evident intent to preempt
• C. State law may have more stringent standards
• D. Implied preemption occurs when state law is inconsistent with federal objectives and Congress intends to preempt

Answer: (D)

Implied preemption happens when federal law overrides state law even without an explicit preemption clause. It kicks in when a state rule conflicts with federal objectives or obstructs the federal regulatory scheme, and when Congress’s intent to preempt can be inferred from that scheme. The statement captures this: a state law is displaced where it is inconsistent with federal objectives and Congress intends to preempt. That combination—inconsistency with federal aims plus Congress’s intended preemption—is the hallmark of implied preemption, making it the best description. The other options miss the point: implied preemption does not require explicit language, mutual exclusivity isn’t the defining feature, and mere potential for stricter state standards doesn’t alone establish preemption.
