Inhouse counsel /ˈɪnhaʊs ˈkaʊns(ə)l/ (n.) A peculiar breed of legal wordwright whose expertise chiefly resides in knowing enough about the law to frame the right question for someone else, but artfully disclaiming enough knowledge to actually answer it; and the tactical acumen to throw such a hospital pass to such an unsuspecting third party without anyone twigging that she has done it. You can find detailed criteria — what it takes to excel at the job of steering emails — here.
The person who proves best at this behaviour over a sustained period of time gets to be general counsel.
