Oh, it's not that at all. The problem with auction procedures in this case wasn't the actual auction methodology, but the lack of notice and the difficulty of submitting a bid. In any case, a judge does make the decisions in a bankruptcy court when the parties disagree about things. In this case, the creditors are not in agreement that this was okay.

A sealed-bid auction is a bit non-standard in a bankruptcy, but there should be no problem if all the bids get revealed post-facto. I wouldn't be surprised if this was mentioned in the opinion because it doesn't help you say that the auction was fair in light of everything else (if you're going to do non-standard stiff, do it in a very clean-looking way).
