While I will agree with you that SJ's are rarely granted, I can not totally agree with you on this specific motion for SJ.
In the hearing where both parties presented their arguments to the SJ motion, WMI pointed out that JPM has not produced one shred of actual evidence that the $4bil belongs to JPM.
After 16 months JPM still has not produced any actual evidence or supporting facts to prove that their claim is valid.
From the recent WMI 8k:
Prior to the Petition Date, WMI and WMB jointly maintained their respective financial records. As a result of the Sale, many of the Debtors’ books and records were seized by the FDIC and transferred to the custody of JPMorgan. Accordingly, the Debtors are not in control of certain information relating to their operations and financial affairs, including, but not limited to, certain accounting information. In addition, as of the date of the Sale, substantially all of WMB’s employees became employees of JPMorgan. Accordingly, this Monthly Operating Report was prepared, in part, based upon the information and work product and/or representations made available to the Debtors and their professionals by representatives of WMB and JPMorgan.
JPM has had the "books", and basically all of WMB's employees this entire time(16 months)....and they still have not produced any evidence to back their claim.
I personally believe that once the FDIC motion is crushed, the SJ will be granted to WMI. If, for some unfathomable reason, the judge grants the FDIC their request, then the SJ will be postponed further or denied and sent to trial(non jury).
We will see on Friday.
