The opinion
MacKINNON, Senior Circuit Judge
(concurring).
In this case it should be pointed out that the CAB doubted that the prior approval of the seniority lists by the arbitrator and the CAB precluded the present claims of IBT and IAM, but the CAB made it clear that Pan Am and TWU would be “free to argue” before the arbitrator that reconsideration of the seniority lists would be unfair to them. Order 82-8-63 at 5 (JA 5). Subject to calling attention to this comment, I concur in the foregoing opinion.
