Rules of conduct that have been approved by the government and which are in force over a certain territory and which must be obeyed by all persons on that territory.


A rule of conduct or action prescribed or formally recognized as binding or enforced by a controlling authority. Dictionary

n. 1) any system of regulations to govern the conduct of the people of a community, society or nation, in response to the need for regularity, consistency and justice based upon collective human experience. Custom or conduct governed by the force of the local king were replaced by laws almost as soon as man learned to write. The earliest lawbook was written about 2100 B.C. for Ur-Nammu, king of Ur, a Middle Eastern city-state. Within three centuries Hammurabi, king of Babylonia, had enumerated laws of private conduct, business and legal precedents, of which 282 articles have survived. The term "eye for an eye" (or the equivalent value) is found there, as is drowning as punishment for adultery by a wife (while a husband could have slave concubines), and unequal treatment of the rich and the poor was codified here first. It took another thousand years before written law codes developed among the Greek city-states (particularly Athens) and Israel. China developed similar rules of conduct, as did Egypt. The first law system which has a direct influence on the American legal system was the codification of all classic law ordered by the Roman Emperor Justinian in 528 and completed by 534, becoming the law of the Roman empire. This is known as the Justinian Code, upon which most of the legal systems of most European nations are based to this day. The principal source of American law is the common law, which had its roots about the same time as Justinian, among Angles, Britons and later Saxons in Britain. William the Conqueror arrived in 1066 and combined the best of this Anglo-Saxon law with Norman law, which resulted in the English common law, much of which was by custom and precedent rather than by written code. The American colonies followed the English Common Law with minor variations, and the four-volume Commentaries on the Laws of England by Sir William Blackstone (completed in 1769) was the legal "bible" for all American frontier lawyers and influenced the development of state codes of law. To a great extent common law has been replaced by written statutes, and a gigantic body of such statutes have been enacted by federal and state legislatures supposedly in response to the greater complexity of modern life. 2) n. a statute, ordinance or regulation enacted by the legislative branch of a government and signed into law, or in some nations created by decree without any democratic process. This is distinguished from "natural law," which is not based on statute, but on alleged common understanding of what is right and proper (often based on moral and religious precepts as well as common understanding of fairness and justice). 3) n. a generic term for any body of regulations for conduct, including specialized rules (military law), moral conduct under various religions and for organizations, usually called "bylaws."

A body of rules of conduct of binding legal force and effect, prescribed, recognized, and enforced by controlling authority.

In U.S. law, the word law refers to any rule that if broken subjects a party to criminal punishment or civil liability. Laws in the United States are made by federal, state, and local legislatures, judges, the president, state governors, and administrative agencies.

Law in the United States is a mosaic of statutes, treaties, case law, Administrative Agency regulations, executive orders, and local laws. U.S. law can be bewildering because the laws of the various jurisdictions—federal, state, and local—are sometimes in conflict. Moreover, U.S. law is not static. New laws are regularly introduced, old laws are repealed, and existing laws are modified, so the precise definition of a particular law may be different in the future from what it is today.


Law is a system of rules, usually enforced through a set of institutions. It shapes politics, economics and society in numerous ways and serves as a primary social mediator of relations between people. Contract law regulates everything from buying a bus ticket to trading on derivatives markets. Property law defines rights and obligations related to the transfer and title of personal (often referred to as chattel) and real property. Trust law applies to assets held for investment and financial security, while tort law allows claims for compensation if a person's rights or property are harmed. If the harm is criminalised in a statute, criminal law offers means by which the state can prosecute the perpetrator. Constitutional law provides a framework for the creation of law, the protection of human rights and the election of political representatives. Administrative law is used to review the decisions of government agencies, while international law governs affairs between sovereign nation states in activities ranging from trade to environmental regulation or military action. Writing in 350 BC, the Greek philosopher Aristotle declared, "The rule of law is better than the rule of any individual."

Legal systems elaborate rights and responsibilities in a variety of ways. A general distinction can be made between civil law jurisdictions, which codify their laws, and common law systems, where judge made law is not consolidated. In some countries, religion still informs the law. Law provides a rich source of scholarly inquiry, into legal history, philosophy, economic analysis or sociology. Law also raises important and complex issues concerning equality, fairness and justice. "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." In a typical democracy, 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.
