Which statement best distinguishes substantive law from procedural law?

• A. Substantive defines rights and duties; procedural governs enforcement processes.
• B. Substantive governs how trials are conducted; procedural defines rights.
• C. Substantive is about evidence; procedural is about sentencing.
• D. Substantive applies only to civil cases; procedural only to criminal.

Answer: (A)

Substantive law defines rights and duties — the actual rules that determine what people may or may not do and what remedies or penalties follow from violations. It tells you, for example, what constitutes a breach of contract, what crimes exist and their penalties, or who owns a piece of property. Procedural law, on the other hand, governs the mechanics of enforcing those rules: how a case is started, what steps must be followed, how evidence is gathered and admitted, what rights a defendant has, and how judgments are reviewed or appealed.

So a contract breach, for instance, is a substantive issue (what counts as a breach and what remedy is available). The process of suing for that breach, the rules about presenting evidence, timelines, and due process rights are procedural concerns. The other statements misplace elements: procedural governs trial procedures and rules of evidence, not substantive rights; substantive isn’t confined to civil cases alone—both civil and criminal contexts rely on substantive rules, with procedural rules applying to both as well.
