What Is Law?

Law is a system of rules that a society or country recognizes as regulating its members’ behaviour. These rules may be written or unwritten and they usually come with the threat of sanctions (e.g. fines or imprisonment) if they are broken. Law covers a wide variety of activities and topics, from international law to family law, and from criminal law to corporate law.

Laws vary across countries, and there is a great deal of debate about what legal systems should look like. One of the big issues is whether there should be a single universal definition of law. This would make it easier to compare different laws from different countries, and it could also help in international negotiations about trade or the environment.

In most countries, laws are compiled by groups of politicians in a legislature (such as a parliament or congress) that is elected to do so by the citizens of a country. The legislators create the overall framework of law and then make further laws for more specific matters. Laws can cover a wide range of activities, such as contracts, property, the environment or war.

A good example is copyright law, which protects people’s rights over things they create (like art or music) from being stolen by others. Another area of law that is very broad is intellectual property, which includes patents and trademarks. Companies have a legal duty to ensure that they do not infringe other people’s patents and trademarks when they market their own products or services.

Other areas of law include the law of torts, which helps people claim compensation when they are harmed by others or have their property damaged. Contract law regulates agreements between people to exchange goods or services. Trust law sets out rules for money that is invested in something, such as a pension fund. Property law defines people’s rights and duties toward their homes, land or other possessions. Labour law focuses on the tripartite industrial relationship between worker, employer and trade union, including regulation of collective bargaining and rights to strike. Aviation law sets out the regulations and standards that must be met by planes and their pilots, and is mostly aligned with the recommendations or mandatory standards of the International Civil Aviation Organisation or ICAO.

The purpose of law is to keep the peace, maintain the status quo, preserve individual and community rights, promote social justice and provide orderly social change. However, some systems of law serve these goals better than others. For example, a state with an authoritarian government might keep the peace and maintain order, but it may oppress minorities or restrict freedom of speech. A judicial system, on the other hand, should be a neutral, impartial and independent arbiter of the facts of a case and of the rights of individuals. This is why most countries have a constitutional separation of powers between the legislative, executive and judicial branches of government.
