Which law specifies how rights and duties may be enforced?

The correct choice is procedural law, which defines the rules and processes that govern how rights and duties are enforced within the legal system. This includes the steps that parties must follow to bring a case to court, the procedures for conducting trials, the methods of appealing a decision, and how evidence is presented. Procedural law ensures that the legal system operates fairly and efficiently, providing a framework for resolving disputes and enforcing legal rights.

In contrast, statutory law refers to laws that are enacted by legislative bodies and typically establish specific rights and responsibilities but do not dictate the procedures for enforcement. Substantive law encompasses the body of law that defines rights, duties, and obligations, focusing on the actual substance of legal claims and defenses rather than the methods used to enforce them. Case law, stemming from judicial decisions, interprets statutory and substantive law but does not specifically outline procedures for enforcement. Understanding the function of procedural law is essential for navigating the legal process effectively.
