Which term refers to non-essential statements of law made in judicial opinions?

The term that refers to non-essential statements of law made in judicial opinions is "dictum." In legal contexts, dicta (plural of dictum) are remarks or observations made by a judge that are not necessary to the decision in the case. Although they can provide insight or guidance on legal principles, they do not establish binding precedent. This contrasts with the holding of a case, which is the legal principle that is essential to resolving the case and is binding in future cases.

The other terms have specific legal meanings and contexts that do not align with the definition of non-essential statements of law. For instance, "interlocutory" pertains to a temporary or provisional order made during the course of litigation and is not related to judicial commentary. An "easement" refers to a legal right to use someone else's land for a specific purpose, while "canon" typically refers to a rule or law, especially in ecclesiastical law, rather than non-essential remarks in judicial opinions.
