Law is a set of rules made by a government that people must follow. It sets out what is and is not allowed, and if people break those laws they will face punishment. The purpose of law is to protect people and make sure that everyone has a fair opportunity to get justice. The benefits of having a well-functioning system of laws are vast and varied, from stability and equality to freedom from corruption and unjust treatment. Law also ensures that victims receive compensation when they suffer a loss, and it allows citizens to have recourse against those who harm them.
The precise definition of law is a topic of debate and has changed over time. The word’s meaning is generally agreed to be the body of rules imposed by a government that must be obeyed or punished, but some people also use it more broadly to mean any strong rule that must be followed. For example, house rules may be described as laws, and behaviours that a person might do instinctively or spontaneously, such as trying to save their life when in danger, could also be considered to be laws.
Legal systems vary enormously between nations. The creation of law is a matter of political power, which in turn influences how a nation looks and functions. It is a complex field of study, and the varying approaches to it can explain why nations appear so different.
There are four main purposes of law: establishing standards, maintaining order, resolving disputes and protecting liberties and rights. These broad areas of law can then be further subdivided into specific fields, for example: labour law is the study of a tripartite industrial relationship between employer, trade union and employee; contract law covers commercial transactions; property law defines ownership of personal assets; and criminal law sets out how crimes should be prosecuted.
In addition to these general areas of law, the law also encompasses many sub-fields including administrative law, criminology, criminal procedure and civil litigation, international law, maritime law, medical jurisprudence, constitutional law and corporate law. Moreover, the practice of law involves many other specialisms, such as immigration and asylum law, taxation law and criminal defence.
The complexity of the legal system can lead to problems. For instance, the rigidity of laws can slow down the pace at which a society changes. Moreover, judges can be subject to bias and personal opinions. The laws must therefore be fixed so that they can better withstand individual judgements by providing stable and reliable principles of law. These principles can also help judges to make sound decisions and avoid ill-judged interpretations of the law. This is important because a judge’s faulty or prejudiced judgement can affect the lives of people who are entrusting their lives to the courts. For this reason, a legal system that has fixed principles is preferable to one that is purely judge-based.
