I'm no lawyer but I'll take WAG at it.
If the examiner is stonewalled by the debtors, JPM, and FDIC, that is exactly what the examiner reports. The decision on the DS and POR is an easy one for the judge and she appoints a trustee because the debtors are not forthcoming with vital information to bring this BK case to a fair conclusion.
The trustee may have to start over with asset evaluation, asset transferred (which JPM and FDIC will probably still won't comply with), any potential litigation against JPM and FDIC. Eventually, rulings will go against JPM and FDIC that will become public...hopefully rulings awarding WMI for damages, etc...
All of this in the next 1-3 years, and I don't think 3 years out is an exaggeration. Who would have thought (other than Chiron) we would be where we are almost two years into this?
WithCatz, Mordi, etc can chime in with the professional advice here if you like.
