The Purpose of Law


Law is the system of rules a society develops and enforces to deal with problems such as crime, business agreements and social relationships. It can also be used to refer to the people who study and work within systems of laws, including judges, lawyers and advocates.

Legal rules are created by a variety of means. They can be enacted by a legislature, resulting in statutes, decrees and regulations, or established through precedent in common law jurisdictions. Laws can also be formulated by religious institutions, such as Jewish Halakha and Islamic Sharia, or the Christian canon. The exact nature of law is highly complex. It has a normative element that prescribes how people should behave and is rooted in concepts of justice, morality and the will of a deity.

From an ontological perspective, Holmes’s definition of law provides a building block for understanding the role of law in a society. As part of this, he suggests that “law does not exist because it is proclaimed, recognized or enforced; it exists because bad men expect it to be enforced.”

Regardless of its ontological basis, the precise nature of law has been an ongoing subject of debate. Some theorists consider law to be an objective concept, like the speed of light, while others see it as a subjective notion that is influenced by individual beliefs and biases.

The purpose of law is to ensure that citizens live in a safe and just society. This is achieved by resolving disputes through peaceful means rather than conflict, for example, when two people claim to own the same land. The law will determine who is the true owner and protect their rights.

In addition, the law can help to prevent economic crises by setting rules on how banks and financial institutions should operate. Banking law, for example, sets minimum standards on the amount of capital that a bank must hold and rules about best practice for investment. This helps to reduce the risk of a banking crisis, such as the Wall Street Crash of 1929.

Other purposes of the law include the protection of minors, the abolition of slavery and the prevention of war. The legal system also promotes freedom of speech and the press, protects privacy and the right to a fair trial. The laws of a country can also be a guide for foreign residents seeking asylum.

The law is vast and reaches into virtually every aspect of life. The most prominent areas of law are criminal and civil law, though there is also a strong body of administrative law, which encompasses everything from property laws to immigration. Evidence law is another important area, as it deals with which materials are admissible in courts for a case to be built. Finally, there is a large field of public and private international law, which deals with treaties, international organizations and human rights issues. This is a broad field that is constantly evolving, as nations and individuals become more interconnected globally.
