That's the way I see it. Trump could appeal with an 8th Amendment argument, but bonding companies are afraid to pay the bond, perhaps because NY State is utterly corrupt, and because the NY economy's future is unknown. As I understand it, NY law requires payment or a bond before an appeal is allowed. Catch-22.
Trump’s biggest problems in getting funding for a bond are that none of the 30 companies he approached for a bond will write one for more than $100 million, in the best of circumstances.
The second problem we should all recognize (even though we vigorously oppose it) is that the Trump Organization LLC has now been found liable for multiple and significant business frauds conducted as a pattern and practice of the business. Unless that finding by the trial court (Engoron) is somehow overturned by the appellate courts, no publicly traded firm will ever loan him money again. He’ll have to get private loans from the Saudis or another friendly government.
