Law is a set of rules that are created and enforced by social or governmental institutions to regulate behavior. It is a scheme of social control that teaches us how to behave properly and informs us of the rules we all must follow. The precise definition of law is a matter of longstanding debate, and there have been several attempts to produce a universally acceptable definition. Some definitions of law include:

• A system of rules and guidelines: Law is a system of rules and guidelines which are enforced through social institutions to govern behavior.
• A rule of conduct or action: Law is a binding custom or practice of a community, a rule of conduct or action prescribed or formally recognized as binding or enforced by a controlling authority.
• A scheme of social control: Law is a scheme of social control that regulates behavior and teaches us how to behave properly.

Laws are created by various entities, including governments, courts, and other institutions. They are unique to each country and are enforced through social institutions. The courts play an integral role in maintaining the rule of law, particularly when they hear cases that involve the interpretation of the Constitution or laws passed by Congress. The rule of law is a principle under which all persons, institutions, and entities are accountable to laws that are publicly promulgated, equally enforced, independently adjudicated, and consistent with international human rights principles.
