Often the judge invites someone, on a quick straw poll of the jury, to act as foreman to ask questions which the jury have come up with during a trial. And often that person is also the foreman who returns the verdict. I once saw such an instant foreman ask "Why is defence counsel asking a lot of questions which have no relevance and which only serve to annoy us?" ! Must say, I was wondering that myself, and I was prosecuting LOL. But mostly the right to ask questions is sparingly used, and, when it is, it is often about local knowledge, for example counsel may be mispronouncing a local place name, or mistakenly calling a Street a Road when there is both a Road and a Street with the same name
