Well apparently, alerted or not, it was misexplained at some time during the auction, so there probably was UI. From a situation of ignorance as to the hands and exactly what happened, one might hazard a guess that S's calls have a look of unauthorised panic to them. But we would need to know N and S's cards, and exactly what was explained when. Without that, we can't judge whether in fact there was abuse of UI.
I fail to see how South has UI, as he is the one who would have alerted 2
♦. So I fail to understand the remark that south's calls have the look of unauthorized panic. It would seem perfectly reasonable if he has spades for him to rebid spades. The question that would have to be looked into is whether North, who does have UI, has taken advantage of the UI.
