What is common law ?

Common law does not mean the law that is common. It has a great definition. As distinguished from the Roman law, the modern civil law, the canon law, and other systems, the common law is that body of law and juristic theory which was originated, developed, and formulated and is administered in England, and has obtained among most of the states and peoples of Anglo-Saxon stock.

As distinguished from law created by the enactment of legislatures, the common law comprises the body of those principles and rules of action, relating to the government and security of persons and property, which derive their authority solely from usages and customs of immemorial antiquity, or from the judgments and decrees of the courts recognizing, affirming, and enforcing such usages and customs; and, in this sense, particularly the ancient unwritten law of England.

 As distinguished from equity law, it is a body of rules and principles, written or unwritten, which are of fixed and immutable authority, and which must be applied to controversies rigorously and in their entirety, and cannot be modified to suit the peculiarities of a specific case, or colored by any judicial discretion, and which rests confessedly upon custom or statute, as distinguished from any claim to ethical superiority.

 In a wider sense than any of the foregoing, the “common law” may designate all that part of the positive law, juristic theory, and ancient custom of any state or nation which is of general and universal application, thus marking off special or local rules or customs. As a compound adjective “common-law” is understood as contrasted with or opposed to “statutory,” and sometimes also to “equitable” or to “criminal.”
