Well, all I can say is that I felt completely comfortable relying on the translator.
I'm here to answer questions, not to ask them, but I'd like you to think of a client you might have had where you asked them, “Look, we have our choice of judges, A and B. Judge A speaks both languages pretty well, but he's not as good a judge as Judge B. If you go with Judge B, you're going to have to rely on the translator. Which judge will you take?”
