The lawyer issued a statement saying the accusations against his client are utterly unfounded.

A formal four-character compound (四字熟語(よじじゅくご)) frequently used in news, legal contexts, and public denials. It is a strong, emphatic way to deny something — stronger than simply saying 嘘(うそ) (lie) because it asserts a complete absence of factual basis.
