What Is Law?

Written by



Law is the system of rules that a group or community recognizes as regulating its members’ actions. This body of rules is enforced by a controlling authority, typically through penalties. Law consists of a wide range of areas, such as contracts, property, criminal, employment and administrative laws. It also covers societal restrictions and their enforcement, such as those that govern sexual behavior, political speech, and the rights of minors.

Legal systems differ from one country to the next, with some based on judicial decisions and others relying on codes of conduct, statutes and case law. Generally speaking, however, most countries have some form of law. For example, the United States employs a common law system that relies on the decisions of judges in particular cases and the compilations of those decisions into what is known as “case law.” Other countries, such as Japan, operate under a civil code system.

The primary function of law is to organize and control society, as well as to provide social justice to all its citizens regardless of background or social class. This includes ensuring that people receive the same punishment for the same crime and that property is protected. It is also important that the government is held accountable for its actions, and that checks on power exist so that an authoritarian or dictatorial regime is not allowed to develop.

In many countries, the main law-making body is a legislature that creates legislation and enacts it into law. It may be supplemented by a constitutional court, which ensures that the legislative process is conducted fairly and reflects the wishes of the people. A constitution may also serve to limit the powers of a legislature, such as prohibiting the passage of laws that infringe on personal liberties.

A variety of specialties exist within law, such as environmental, labour and family law. These are generally focused on specific areas of concern to a certain part of the population or a certain type of industry. For example, labour law studies the tripartite relationship of employer, worker and trade union, and concerns issues like collective bargaining and the right to strike. Environmental law is devoted to protecting the environment and regulating industries that may damage it. And family law deals with relationships and the rights of parents to children.

Other specialized fields of law include constitutional, criminal, and international law. The latter concerns the rights and obligations of individuals in a nation, as well as the relationships between nations and the international world. It may be important for nations to coordinate their laws with each other in order to avoid conflicts of interest and to allow for international commerce. In the area of international law, treaties and agreements are often crucial to the regulation of various activities such as trade, travel, monetary policy and intellectual property. In the case of a conflict between two nations, a neutral arbiter may be necessary to determine the outcome. This is called arbitration.
