I'm not an expert by any means. But in following fed litigation over the years, I cannot recall many instances where a court overturned an already accepted settlement agreement. Yes, occasionally the judge raises concerns at the settlement conference. But that already happened.
The court would have to allow you to participate third party intervenor at this late hour, which it has no obligation to do, and then allow that intervenor (you) to make constitutional challenges to an already accepted settlement agreement. Was KiwiFarms timely in challenging said court accepted settlement? Now it sounds like you would almost have to file a 60(b) motion, which is another minefield.
Seems like a long shot to me. Considering Mr. Jones' DCMA is probably frivolous, he is too poor to afford a lawyer, and Mr. Turkey cannot legally represent him- what exactly is the danger to the Farms? Why does this enable Mr. Turkey to file more lawsuits then he otherwise feels compelled to?
