Law is the system of rules and regulations that a society or government creates to deal with issues such as crime, business agreements and social relationships. Law can also refer to the people who work in this system, such as lawyers and judges.
Law shapes politics, economics, history and society in many ways. It can also raise questions about equality and fairness. For example, it is generally accepted that laws should not discriminate against people for their race, ethnicity, religion or sexual orientation.
The precise definition of law is a matter of debate, but it has generally been regarded as the set of rules that people and communities adopt and enforce to govern themselves. This set of rules may be referred to as civil law, criminal law or common law. Civil law deals with disputes between individuals, and it includes fields such as contract law (dealings between people), tort law (when someone is harmed) and property law (how people are entitled to and responsible for their possessions). Criminal law deals with offenses against the state, which can include anything from murder to tax fraud.
People rely on the law to ensure that they live and work in a safe and stable environment. This means that they need to be able to trust the police and public officials, and they must have confidence that the courts will settle their differences fairly.
However, even in the best-ordered societies, disagreements can arise. The law enables them to resolve these conflicts peacefully rather than violently, for example when two people want to use the same piece of land. In this case, they can turn to the courts for help and the court will decide who owns it.
Another purpose of the law is to prevent disorder and corruption. It can do this by setting standards of conduct that everyone must follow and by punishing those who break the law. The law can also protect people from exploitation by employers and other powerful people.
Almost every country has its own legal system. Some countries have a civil law system, where a central body codifies and consolidates the laws, while others have a common law system in which judge-made precedent is binding. Some countries, such as France and Switzerland, have mixed legal systems.
Law is the subject of a great deal of scholarly study. The field contains a wide range of subjects, including legal history, philosophy, economic analysis and sociology. It is also a career choice for many people, especially those interested in promoting justice and protecting the rights of others. Those who wish to become lawyers must complete a law degree program, and those who want to work in the judicial system must pass a bar exam. People who work in the governmental and non-governmental sector often specialize in different areas of law. For example, prosecutors are specialized in charging crimes, and public defenders represent those who can’t afford private lawyers in criminal cases.
