English Common Law

In common law legal systems, the law is created and/or refined by judges: a decision in the case currently pending depends on decisions in previous cases and affects the law to be applied in future cases. When there is no authoritative statement of the law, common law judges have the authority and duty to "make" law by creating precedent. The body of precedent is called "common law" and it binds future decisions. In future cases, when parties disagree on what the law is, an "ideal" common law court looks to past precedential decisions of relevant courts. If a similar dispute has been resolved in the past, the court is bound to follow the reasoning used in the prior decision (this principle is known as stare decisis). If, however, the court finds that the current dispute is fundamentally distinct from all previous cases, it will decide as a "matter of first impression." Thereafter, the new decision becomes precedent, and will bind future courts under the principle of stare decisis.

English law, the legal system of England and Wales, is the basis of common law legal systems throughout the world (as opposed to civil law or pluralist systems in other countries, such as Scots law). It was exported to Commonwealth countries while the British Empire was established and maintained, and it forms the basis of the jurisprudence of most of those countries. English law prior to the American revolution is still part of the law of the United States, except in Louisiana, and provides the basis for many American legal traditions and policies, though it has no superseding jurisdiction.
