The Numerian Inquisition was a type of inquisition agency that would bring those subject to questioning before it.
When Tuvix was called by Captain Kathryn Janeway to USS Voyager's briefing room in 2372 to discuss the possibility of ending his life to save Tuvok and Neelix, Tuvix asked "I feel as though I've been dragged before the Numerian Inquisition." (VOY: "Tuvix")
