With respect to the first question, if the appellate body rules in Canada's favour and Norway's favour, then the EU will be obliged to bring their regime into compliance. There will be a reasonable period of time for them to do so, as is normal in any WTO case. The WTO cases often involve laws and regulations, which as we all know take some time to change when they have to be changed for whatever reason. So the EU would be obliged to come into compliance over a reasonable period of time, if that is the way things turn out.
With respect to your second question on what the future might hold, I'm afraid that's a very difficult question and it really involves a prediction and any number of variables related to both human decisions and objectives and to market fundamentals that present a rather significant overlay in terms of uncertainties.
