Which statement about the binding effect of primary authorities is accurate?

• A. They bind only the highest court.
• B. They are binding on courts below them within the same jurisdiction.
• C. They bind all jurisdictions universally.
• D. They bind only if a higher authority says so.

Answer: (B)

The main idea here is how binding authority works within a legal system. In a given jurisdiction, primary authorities such as statutes, constitutions, and court decisions are binding on courts that sit below them in the judicial hierarchy. This downward binding is the essence of stare decisis: higher courts’ rulings and the text of statutes guide and control lower courts’ conclusions. So a decision from a higher court binds all courts beneath it in that jurisdiction, and statutes bind all courts unless their application is constitutionally problematic or limited by the statute itself. That’s why the statement that primary authorities bind courts below them within the same jurisdiction is the best description.

The other options misstate the hierarchy. Binding only the highest court would reverse the actual structure, as lower courts must follow higher authorities, not the other way around. Claiming binding across all jurisdictions universally ignores the jurisdictional limits that assign binding force to authorities within a specific system. Saying binding occurs only if a higher authority says so ignores that primary authorities themselves derive their binding force from their place in the hierarchy, not from a separate later directive.
