Law

Law is a system of rules, usually enforced through a set of institutions.It shapes politics, economics and society in numerous ways. Contract law regulates everything from buying a bus ticket to trading swaptions on a derivatives market. Property law defines rights and obligations related to transfer and title of personal and real property, for instance, in mortgaging or renting a home. Trust law applies to assets held for investment and financial security, such as pension funds. Tort law allows claims for compensation when someone or their property is injured or harmed. If the harm is criminalised in a penal code, criminal law offers means by which the state prosecutes and punishes the perpetrator. Constitutional law provides a framework for creating laws, protecting people's human rights, and electing political representatives. Administrative law relates to the activities of administrative agencies of government. International law regulates affairs between sovereign nation-states in everything from trade to the environment to military action. Law manifests itself throughout the community in many more ways, and serves as the foremost social mediator of relations between people. "The rule of law", wrote the ancient Greek philosopher Aristotle in 350 BC, "is better than the rule of any individual."

Legal systems around the world elaborate legal rights and responsibilities in different ways. A basic distinction is made between civil law jurisdictions and systems using common law. Some countries persist in basing their law on religious texts. Scholars investigate the nature of law through many perspectives, including legal history and philosophy, or social sciences such as economics and sociology. The study of law raises important questions about equality, fairness, liberty and justice, which are not always simple. "In its majestic equality", said the author Anatole France in 1894, "the law forbids rich and poor alike to sleep under bridges, beg in the streets and steal loaves of bread." On the other hand, philosopher Friedrich von Hayek said: "Equality before the law and material equality are therefore not only different but are in conflict with each other; and we can achieve either the one or the other, but not both at the same time." The central institutions for interpreting and creating law are the three main branches of government, namely an impartial judiciary, a democratic legislature and an accountable executive. To implement and enforce the law and provide services to the public, a government's bureaucracy, the military and police are vital. While all these organs of the state are creatures created and bound by law, an independent legal profession and a vibrant civil society inform and support their progress.
