Ivanka appealed mostly on the ground of statute of limitations. Several issues. The main two were 6 or 3 year statute of limitations (answer 6), and whether a "tolling agreement" applied to her. The tolling agreement extended limitations by 18 months, I think, and was executed by the Trump Org, only, and purported to bind all officers and directors, affiliates, etc.
The combination of the tolling agreement and the 6 year limitations period put the "pumpkin day" back to 2014 for those bound by the agreement, and 2016 for those not bound by the agreement.
Vanky was dismissed from the case because there were no allegations that she did anything after 2016, and, by the time of the tolling agreement, she was not an officer or director of Trump Org and thus not bound by it.
The appeals court in passing suggested that the trial court could/should evaluate or re-evaluate its holdings in light of the decision, which Engoron did on summary judgment, holding and citing case law that a tolling agreement signed on behalf of an organization could bind individual officers and directors.
One other little thing, the court mentioned that causes of action "accrue" (when they count for purposes of limitations, as in did the fraud occur before 2016 or 2014) when "the transaction is complete." Trump wants that to mean when the loans closed, which were all in like 2011 or 2012. But there were separate fraudulent acts occurring in connection with loan covenants well into 2014 and 2016.
