No worry, the statute of limitation hasn't expired. Many cases are kind of like ongoing in the last few years.
If you file a court case, your name will be written into history. It can be a big honor, given this is the last piece of unfinished work for the 2008 Housing Crisis. The simple case can easily be won this time. The NWS term is too aggressive and so completely ILLEGAL. "I am afraid you cannot afford the interest payment. So starting now on, you pay me everything you got including any income or earning perpetually as dividend". Anyone has some sense know that this is illegal. You may cite the example of payments in 2012. In the same year that NWS was announced, FnF paid $121B to UST for a loan of $191B. This is written in their annual reports. This cannot be a coincidence, given the heads-up by Ms. McFarland to FHFA management that "Fannie will be in golden era of profitability". No court dares ruling that NWS loan term is valid. As SCOTUS hinted, why not suit from UNCONSTITUTIONAL prospective.
I agree that JPS cannot be diluted. But still, we don't know how many more years we need to wait. The above suggested court case will kill the NWS quickly. We don't even need to argue about death spiral. We can focus on one thing and one thing only: the NWS loan term.
A few thousand dollar to kickoff the lawsuit is needed. Then, you can go crowd funding. I will be the first one to respond.
