Case Law – this legal term refers to the system of published legal decisions of the local courts within particular jurisdiction, which, because of the “concept of precedent”, consists of a huge part of the legal provisions that have legal force within this society. If a rule of law cannot be found within the local statutes, when it could be extracted  in the “case law”. In other words, it represents a principle of law established by concrete judge in concrete heard lawsuit, which legal principle may be used for guidance on other similar lawsuits later in practice, having similar subject and similar circumstances. Case Law, as applicable nowadays within the Common Law system in the United Kingdom and in the United States, is not static as the legislative statutes, but developing through the legal practice.

The legal terms “jurisprudence” and “non-statutory law” have become synonyms for case law.
