What term describes actions taken outside the scope of lawful authority?

The term "ultra vires" is derived from Latin meaning "beyond the powers." It is specifically used to describe actions or decisions taken by an individual or organization that exceed their legal authority or power. In the context of legal terminology, when a governmental body, corporation, or any entity takes action that is outside the limitations set forth by law or regulation, those actions are deemed ultra vires. This can lead to such actions being invalidated or challenged in court, as they do not conform to the legal limits prescribed for that entity.

In contrast, other terms such as "intrajudicial" refer to actions taken within the scope of judicial proceedings, and "intra vires" signifies actions performed within legal or authorized limits. "Exceeding authority" may describe a similar concept informally but does not carry the precise legal significance that "ultra vires" does within legal contexts. Thus, the selection of "ultra vires" aligns directly with the definition sought, emphasizing the critical importance of lawful authority in legal operations.
