Every state or nation has a set of rules by which its citizens live by. These rules are generally written down for future reference by the state or nation’s posterity. This collection of rules is loosely called law and is applicable to any form of organization or society.
Each organization or society has guidelines by which members or citizens live by. These guidelines are found within a document recognized by the people who are part of the organization or society as binding. These guidelines are formalized into what is known as law, which governs interactions among people, within organizations, and the like.
Law establishes authority within an organization such as a government, and is the foundation of the legal system, which exists for the purpose of settling conflicts with regard for the law. Law can exist in varied forms and in numerous settings. International law provides a system of rules for countries or organizations that have a global scope, the United Nations for example. Constitutional and administrative laws establish rules that deal with governance such as a constitution or a statute. Criminal law deals with crime and punishment, providing a method as to how to address offenses and what punishment is commensurate to the crime committed. Contract law deals with agreements that are legally binding upon parties that enter into it. Many other forms of law exist—tort law, civil law, and property law. Some forms of law are broader in their scope, while other forms are sub-categories of more general kinds of law.
