What is Trump’s recourse from here? This bond requirement is preposterous
He can appeal either with or without the bond, but without it the State can start enforcing its judgment against him. So he has to win his appeal to the Appellate Division, First Department (which is unlikely). If he loses there he can appeal to the Court of Appeals (which has a lower case acceptance rate than even the SCOTUS - but there is a quirk, in NY if the Appellate Division rules 3-2, the loser has the RIGHT to appeal to the Court of Appeals, i.e. the COA must hear it). Then he can appeal to the SCOTUS.
Someone more versed in appellate practice will have to opine as to what happens if a judgment gets enforced during appeal, and then the debtor wins the appeal. Does the State have to return what they enforced? Is the appeal dismissed as moot because the judgment has been paid? I don’t actually know the answer to that.
