What Is Law?


Law is a set of rules that are created and enforced by the state to ensure a peaceful society. People often argue about what the law should or shouldn’t be, but at the heart of it is that the law creates a framework for ensuring that all members of society treat each other fairly and equally. If people in a society disagree, the law allows them to solve their problems peacefully rather than fighting (see Dispute resolution). The law can also help to prevent war and protect people from being hurt or killed.

Almost every country has some kind of legal system, but it can differ widely. For example, some countries use common law systems that trace back to England, while others have civil law traditions that originated in France or other parts of Europe. Most jurisdictions have both federal and local laws, with some areas, such as family law, handled only by the state. Other areas, such as aviation and railroad law, are covered by a broad scheme of federal statutes that preempt most state laws.

The precise definition of “law” is a matter of longstanding debate, with scholars arguing that it includes the principles and rules of social or governmental institutions that regulate behavior, and that they are enforceable by force or threat of force. The word is derived from the Latin verb lgis, meaning “to lay down, ordain or establish.”

The law defines the rights and obligations of individuals and collective bodies in society, and how they can be enforced. It also sets out procedures for resolving disputes and interpreting facts. The term “law” can also be used to describe a body of rules that is authoritative and applies universally, such as the constitution of a nation.

Most jurisdictions have a judiciary, which is made up of judges. Judges hear contested cases and determine the guilt or innocence of people who are charged with crimes. They also interpret laws and regulations, and they have the power to remove laws that are unjust or inconsistent with the constitution.

Laws also set out the rights of property owners. They can include the right to ownership of land, buildings, and other physical objects, or the right to intangible property, such as shares in a company. The law can also govern how people invest their money, such as by setting the terms for trusts or for pension funds. The law can also define how to use someone else’s property, such as when you can use the Internet or drive their car.

The law can also be used to control the growth of business and industry. The government can limit the number of companies that can operate in a particular area by requiring licensing or imposing other controls. It can also provide rules for managing the environment and preventing pollution. The law can also govern the relationships between businesses and employees, such as when an employee must be paid if they are fired for a valid reason or when employers must give workers time off for personal reasons.
