The result is not so dismal. The court has the right to rule that the FCC's action is arbitrary and capricious, but they can only rule on what is in the record. Since the record does not contain the redacted technical studies, the ARRL could not make that assertion and the court could not raise the issue sua sponte based on their in camera review of the documents.

Now the case gets remanded and that is where the fun will begin.
