Precedent
From Ballotpedia
In common law a precedent or authority is a legal case establishing a principle or rule that a court may need to adopt when deciding subsequent cases with similar issues or facts. The term may also refer to the collective body of case law that a court should consider when interpreting the law. When a precedent establishes an important legal principle, or represents new or changed law on a particular issue, that precedent is often known as a "landmark decision".
