concurring in No. 25.
Two Courts of Appeals disagreed about the meaning of a federal law, as conscientious federal courts sometimes do. From the point of view of efficient judicial administration the resulting history of this litigation is no subject for applause. But, as the Court points out, no claim was made here that the decision of the Fifth Circuit precluded Judge Hoffman or the Seventh Circuit from remanding the case, and on the merits of that question I agree with the Court that principles of res judicata were inapplicable. In any event, the conflict between the Circuits is now resolved, and what happened here will not happen again.
