Final answer:
Substantive law defines rights and responsibilities, while procedural law governs the process of enforcing those rights and responsibilities.
Step-by-step explanation:
Substantive law refers to laws that define and establish the rights and responsibilities of individuals, while procedural law refers to the rules and guidelines that govern the process of enforcing those rights and responsibilities.
Example: Laws which define the various degrees of murder are substantive laws because they establish what actions constitute murder and the corresponding penalties. On the other hand, laws that protect the right to a speedy trial for people accused of murder are procedural laws because they outline the steps and timeframe for conducting a fair trial.
