A more thorough explanation:

Definition: Latin term meaning "beyond the powers." It refers to actions taken by government bodies or corporations that go beyond the legal limits of their authority.

For example, if a corporation's charter only allows it to operate in one state, but it starts doing business in another state without proper authorization, it is acting ultra vires. Similarly, if a government agency passes a law that goes beyond the powers granted to it by the constitution, it is acting ultra vires.

These examples illustrate how ultra vires actions can have legal consequences. Corporations can face fines or legal action for acting beyond their charter, while government agencies can have their actions declared unconstitutional and overturned by the courts.
