Literally started by saying I'm holding judgement until reading the opinion.
My point is simply that if the reason the judge raised for re-starting the process is solely around the bids being sealed, they're wrong in a provable way.
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).
Which would make sense. That's not what the article quotes as the judge's reason (nor what you've said).
The quote in the article criticises sealed bids. That's mind-blowingly wrong to the point of having substance on appeal. It's so wrong I expressed scepticism it's actually the case, scepticism based on experience evaluating bankruptcy claims.
