Vires

"Vires" is a Latin term meaning "laws" or "strength." In a legal context, it refers to the validity or enforceability of a law, contract, or legal document. When something is "in vires," it means it is within the powers and authority granted by law or regulation. Conversely, "ultra vires" describes actions or decisions taken outside those legal powers, rendering them invalid or unenforceable. Essentially, "vires" relates to the legitimacy and proper authority behind legal acts, ensuring that entities or individuals act within their lawful scope.
