Looked at logically, there was no way they could allow Djokovic to stay and play. He didn't qualify to stay under any immigration rules so allowing him to would be giving him special treatment. The error was in allowing him (and others) to travel in the first place - presumably because somebody thought tennis players in a National tournament were a special case?
