What is the role of precedence and preemption in resolving conflicts among authorities?

• A. They are ignored in multi-jurisdiction problems.
• B. They help determine which authority governs when multiple statutes conflict; apply precedence and consider preemption.
• C. They always mean the older statute wins.
• D. Preemption applies only to private contracts.

Answer: (B)

When authorities clash, precedence sets which rule controls by hierarchy: higher-level or more authoritative sources bind lower ones. In practice, that means constitutional provisions trump federal statutes and regulations, which trump state or local laws. If two sources conflict, you apply the higher authority and, if possible, interpret or harmonize so they can operate together. Preemption is the mechanism behind this: a higher authority can displace a lower one in a given field. If federal law intends to occupy the field or conflicts with state law (expressly or by implication), the federal rule governs and the conflicting state rule does not apply. This idea can also apply within regulation, where a federal rule can preempt a conflicting state or agency rule. Not everything is about contracts—preemption is about which government authority's rules take priority, not private agreements.
