What is the primary function of the judiciary described in Article III of the U.S. Constitution?

• A. Interpret laws and resolve cases and controversies involving federal law and the Constitution
• B. Enforce laws across all branches
• C. Create new statutes for the nation
• D. Advise the President on policy

Answer: (A)

The main idea is that the judiciary’s job is to interpret laws and settle disputes arising under federal law and the Constitution. Article III gives the courts the authority to apply statutes and constitutional provisions to real cases, determine whether government actions align with the Constitution, and provide remedies in disputes between individuals, states, and the federal government. This focus on interpretation and resolution of actual controversies distinguishes the judiciary from the other branches—the executive enforces laws, while the legislature creates them, and policy advisement isn’t a judicial function. The phrase “cases and controversies” also means courts decide only real issues with proper standing, not broad or advisory opinions.
