I knew well DERRIEN. If it had not been demoted, he would have put his tongue in his pocket. By cons, all that is said, is closer to the truth. As just stated an arbitrator operating (sanctioned by the way), many people manage arbitration, are "very limited." Mr Legraƫst say, "I will not give them my business to run." Being arbiter of "high level" is a "photo" taken oneself at some point. Excluding these people were well PLAIRE to their hierarchy. Now they belong to LA hierarchy, they have the charisma and teaching capabilities, allowing the arbitration to GROW function ???
