In law, common law is the body of law formed by judges and comparable quasi-judicial bodies by virtue of being declared in written decisions. It is also known as judicial precedent, judge-made law, or case law. [The fundamental feature of "common law" is that it emerges as precedent. In circumstances where the parties differ on the law, a common law court looks to previous precedential decisions of competent courts and synthesises the principles of those previous cases as applicable to the current facts.
