Which term describes the rules governing legal proceedings and the enforcement of substantive law?

The term that describes the rules governing legal proceedings and the enforcement of substantive law is procedural law. Procedural law outlines the methods and processes through which legal cases are brought before courts and how they are adjudicated. This includes rules related to filing lawsuits, conducting trials, and appealing decisions.

In contrast, substantive law refers to the body of law that defines rights and duties, establishing what individuals can and cannot do, such as criminal laws and civil rights. Judicial independence relates to the concept of an impartial judiciary free from external pressures, ensuring fair administration of justice. Diplomatic immunity refers to the legal immunity granted to diplomats from prosecution under the host country's laws, which does not pertain to the procedures of legal proceedings in the same way that procedural law does. Thus, procedural law is the correct term for the rules that govern the process of legal action and enforcement.
