What term is not commonly used in the context of judicial precedent?

The term "obiter dictum" is not commonly used in the context of judicial precedent compared to terms like "stare decisis" or "ratio decidendi." While "ratio decidendi" refers to the legal principle or rule derived from a case that is binding in future cases, "obiter dictum" refers to remarks or opinions made by a judge that are not essential to the decision and therefore not binding. Though important for understanding a case's context, obiter dicta do not carry the same weight in establishing precedent.
