Not if the Supreme Court rules FHFA is illegally structured and must be walked back. It looks, to me, like the "safer" ruling might be that HERA is not the enacted empowerment government defense attorneys assert because the GSEs used the GSE Act, not HERA, as the authority to impose the NWS. WAY less controversial than a full repeal of the law.
I am surprised that any shareholder would reject this view as a "nothingburger" as it would open the floodgates for a bonanza for JPS as well as common shareholders as direct claims could be resuscitated in the Sweeney court.
