The ancient law of England based upon societal customs and recognized and enforced by the judgments and decrees of the courts. The general body of statutes and case law that governed England and the American colonies prior to the American Revolution.
The principles and rules of action, embodied in case law rather than legislative enactments, applicable to the government and protection of persons and property that derive their authority from the community customs and traditions that evolved over the centuries as interpreted by judicial tribunals.
A designation used to denote the opposite of statutory, equitable, or civil, for example, a common-law action.
The common-law system prevails in England, the United States, and other countries colonized by England. It is distinct from the civil-law system, which predominates in Europe and in areas colonized by France and Spain. The common-law system is used in all the states of the United States except Louisiana, where French CIVIL LAW combined with English CRIMINAL LAW to form a hybrid system. The common-law system is also used in Canada, except in the Province of Quebec, where the French civil-law system prevails.
Anglo-American common law traces its roots to the medieval idea that the law as handed down from the king's courts represented the common custom of the people. It evolved chiefly from three English Crown courts of the twelfth and thirteenth centuries: the Exchequer, the King's Bench, and the COMMON PLEAS. These courts eventually assumed jurisdiction over disputes previously decided by local or manorial courts, such as baronial, admiral's (maritime), guild, and forest courts, whose jurisdiction was limited to specific geographic or subject matter areas. EQUITY courts, which were instituted to provide relief to litigants in cases where common-law relief was unavailable, also merged with common-law courts. This consolidation of jurisdiction over most legal disputes into several courts was the framework for the modern Anglo-American judicial system.
Early common-law procedure was governed by a complex system of PLEADING, under which only the offenses specified in authorized writs could be litigated. Complainants were required to satisfy all the specifications of a writ before they were allowed access to a common-law court. This system was replaced in England and in the United States during the mid-1800s. A streamlined, simplified form of pleading, known as CODE PLEADING or notice pleading, was instituted. Code pleading requires only a plain, factual statement of the dispute by the parties and leaves the determination of issues to the court.
Common-law courts base their decisions on prior judicial pronouncements rather than on legislative enactments. Where a statute governs the dispute, judicial interpretation of that statute determines how the law applies. Common-law judges rely on their predecessors' decisions of actual controversies, rather than on abstract codes or texts, to guide them in applying the law. Common-law judges find the grounds for their decisions in law reports, which contain decisions of past controversies. Under the doctrine of STARE DECISIS, common-law judges are obliged to adhere to previously decided cases, or precedents, where the facts are substantially the same. A court's decision is binding authority for similar cases decided by the same court or by lower courts within the same jurisdiction. The decision is not binding on courts of higher rank within that jurisdiction or in other jurisdictions, but it may be considered as persuasive authority.
Because common-law decisions deal with everyday situations as they occur, social changes, inventions, and discoveries make it necessary for judges sometimes to look outside reported decisions for guidance in a CASE OF FIRST IMPRESSION (previously undetermined legal issue). The common-law system allows judges to look to other jurisdictions or to draw upon past or present judicial experience for analogies to help in making a decision. This flexibility allows common law to deal with changes that lead to unanticipated controversies. At the same time, stare decisis provides certainty, uniformity, and predictability and makes for a stable legal environment.
Under a common-law system, disputes are settled through an adversarial exchange of arguments and evidence. Both parties present their cases before a neutral fact finder, either a judge or a jury. The judge or jury evaluates the evidence, applies the appropriate law to the facts, and renders a judgment in favor of one of the parties. Following the decision, either party may appeal the decision to a higher court. Appellate courts in a common-law system may review only findings of law, not determinations of fact.
Under common law, all citizens, including the highest-ranking officials of the government, are subject to the same set of laws, and the exercise of government power is limited by those laws. The judiciary may review legislation, but only to determine whether it conforms to constitutional requirements.
