A binding precedent is essentially a legal ruling that must be followed by lower courts in future cases. There are a variety of terms that can be used to refer to this concept, including mandatory precedent, authoritative precedent, and precedent with binding effect. In contrast to a persuasive precedent, which may be influential but not necessarily binding on lower courts, binding precedents carry significant weight and are seen as essential components of a consistent and predictable legal system. Some legal systems also make use of the term stare decisis, which essentially means that courts should follow binding precedents unless there is a compelling reason to depart from them.
