RE:RE:just noticedSince the company believed the decision was, on balance, a modest positive, they may have reasonably felt that there was no need for a halt.
I'm guessing the halt was actually called by the exchange at the moment the stock had moved (down) more than 10%.
If some shareholders want to sell in a wild panic in response to one detail (new damages trial), and without bothering to read the decision, then that's up to them.
