Judicial Precedents

Explanation:

In common law, a precedent establishes a principle or rule which is used by other courts or judicial bodies when making decisions on later cases with similar issues and facts.

This is known as stare decisis (to stand upon decisions) and by which precedents are authoritative and binding and must be followed.

Most importantly, the judgement of an higher court is always binding on lower courts.

When a precedent establishes an important legal principle, this is known as a Landmark Judgement.
