recognized agent

The church is the recognized agent of the state for carrying out funerals within a certain framework.

Observers recognized agents of the far-left in this crowd; the apparent purpose of this was to demonize right-wing parties demonstrations and protests against the current government's agenda.

Furthermore, it is a firm rule of the producers that anyone even vaguely connected with the show who receives any sort of submission from anybody other than a recognized agent must return it unread, which is what I am doing in your case too.
