Law is a system of rules that are enforced by social or governmental institutions to regulate behavior and to ensure that individuals and communities adhere to a certain set of principles. Law shapes politics, economics and history, and is the subject of scholarly inquiry in fields such as legal history, philosophy, sociology and economic analysis.

The precise nature of law is a matter of ongoing debate. It has been variously described as a science, an art and a form of justice. Its main purposes are to establish standards, maintain order, resolve disputes and protect liberties and rights.

For example, tort law provides compensation when someone is harmed by the actions of another person or business, whether it is an automobile accident or defamation. Criminal law deals with activities that are considered harmful to the community and punishes offenders. In addition, civil law is the body of rules governing contracts, property ownership and other private matters.

In some countries, such as the United States, a common law system is used, in which case laws are derived from previous judicial decisions and are therefore not written down. Other countries, such as Japan, use a civil law system based on pre-coded laws in which the courts decide cases according to a clear and unchanging set of rules.

Regardless of the country’s type of law, all legal systems are governed by a constitution, whether explicit or tacit, which serves to define the limits of the power of government and protect individual liberty. In the United States, the framers of the constitution established a system in which the legislative, executive and judicial branches are separated into distinct entities in order to prevent any one person or group from wielding absolute power.

The study of law is a rich field of scholarship that has contributed to philosophical and ethical questions about the role and value of authority, and to arguments about what makes something ‘legal’ or not. It has also provided a framework for understanding and managing the relationship between people in different societies and cultures.
