Which term relates to proceedings that are not statutes but rather depend on states of mind?

The term that best relates to proceedings that are not statutes but rather depend on states of mind is "Intent." In legal terms, intent refers to the mental state of a person when committing an act. It is crucial in various legal contexts, particularly in determining liability and culpability in tort law and criminal law.

Intent influences how actions are interpreted and the consequences that follow. For example, whether a person acted with intentionality can affect the severity of a charge or the remedies available in a tort case. This concept denotes that certain legal proceedings and judgments hinge upon the mental state behind an action, rather than on physical evidence alone.

Other terms provided do not directly pertain to the mental state aspect of legal proceedings. "Inter vivos" refers to transactions or actions that occur during a person's lifetime, often in the context of trusts or estates. "Interlocutory" describes temporary court orders or decisions issued during the course of litigation, which do not assess mental states but rather procedural matters. "Irrelevant" pertains to information that is not applicable or pertinent to the case at hand and does not involve considerations of intent or mental state.

Understanding these distinctions helps clarify why intent is the most appropriate term in the context provided.
