Which statement best describes the differences among case law, procedural law, and statutory law?

• A. Procedural Law Governs Enforcement Methods; Statutory Law Is Enacted By Legislatures; Case Law Is The Law Established By Former Court Decisions
• B. Procedural Law And Statutory Law Are The Same; Case Law Is Historical
• C. Statutory Law Governs How Courts Operate; Procedural Law Relates To Criminal Penalties; Case Law Has No Role
• D. All Three Terms Refer To The Same Concept

Answer: (A)

Understanding the sources and roles of different types of law helps you see how rules are created, applied, and enforced. Statutory law is the collection of written rules created by legislatures—these are the actual laws that set out prohibitions, duties, and penalties. Procedural law governs how the legal process works in practice—how lawsuits are started, how parties are notified, what steps must be followed, and how evidence and trials are conducted. Case law, or common law, grows from judicial decisions; it interprets statutes, resolves ambiguities, and creates precedents that guide future rulings.

The statement that best fits this view says procedural law governs enforcement methods, statutory law is enacted by legislatures, and case law is the law established by former court decisions. This reflects the distinct sources and roles of each type of law. The other options mix up these relationships or deny the role of one area (for example, treating procedural and statutory law as the same, calling case law merely historical, or saying there’s no role for case law).
