On Michael Cohen, Donald Trump's former lawyer and self-described "fixer," Judge Engoron wrote in his ruling that he found the star witness to be a credible witness despite having been convicted of perjury.

"His testimony was significantly compromised by his having pleaded guilty to perjury and by some seeming contradictions in what he said at trial," Engoron wrote. "However, carefully parsed, he testified that although Donald Trump did not expressly direct him to reverse engineer financial statements, he ordered him to do so indirectly, in his 'mob voice.'"

Engoron continued that although the "animosity between the witness and the defendant is palpable, providing Cohen with an incentive to lie, the Court found his testimony credible, based on the relaxed manner in which he testified, the general plausibility of his statements, and, most importantly, the way his testimony was corroborated by other trial evidence."

A "less-forgiving factfinder" might have come to a different conclusion and not believed "a single word of a convicted perjurer," Engoron wrote.

"This factfinder does not believe that pleading guilty to perjury means that you can never tell the truth," he continued. "Michael Cohen told the truth."

Cohen, who pleaded guilty in 2018 to lying to Congress about the Russia probe, addressed the passage on social media, writing on X, "Judge Engoron's determination regarding my veracity at the NYAG Trump civil fraud trial. Michael Cohen told the truth!"

Members of the Trump family and their attorneys roundly called the ruling unjust and indicated they plan to appeal.

Eric Trump told ABC News the judgment against him and his family is "a total joke" and "insane." He said the family will immediately appeal the ruling, which he said shows the court and the attorney general in his opinion are "living in an alternate universe."

Donald Trump Jr. accused the case of being politically motivated.

"We've reached the point where your political beliefs combined with what venue your case is heard are the primary determinants of the outcome; not the facts of the case!" he said in a statement to ABC News.

Donald Trump's lawyer, Chris Kise, also claimed the case was an "unjust political crusade" against the leading Republican presidential candidate and that there was no evidence of fraud.

"Hard to imagine a more unfair process and hard to believe this is happening in America," Kise said, adding that the former president "will of course appeal."

Donald Trump's legal spokesperson, Alina Habba, called the verdict a "manifest injustice" and the "culmination of a multi-year, politically fueled witch hunt."

"Countless hours of testimony proved that there was no wrongdoing, no crime, and no victim," Habba said in a statement. "Given the grave stakes, we trust that the Appellate Division will overturn this egregious verdict and end this relentless persecution against my clients."

The Trump Organization also said the ruling was a "gross miscarriage of justice."

"Every member of the New York business community, no matter the industry, should be gravely concerned with this gross overreach and brazen attempt by the Attorney General to exert limitless power where no private or public harm has been established," a spokesperson said in a statement. "If allowed to stand, this ruling will only further expedite the continuing exodus of companies from New York."

Judge Engoron took direct aim at several of the Trumps' core defenses, including Trump's claim that real estate appraisal is imprecise and subjective, and that property valuations reflect nuances in the market that only sophisticated practitioners can understand.

Engoron called that argument a "great red herring in this case."

"True enough, as appraising is an art as well as a science," Engoron wrote. "However, the science part cannot be fraudulent. When two appraisals rely on starkly different assumptions, that is not evidence of a difference of opinion, that is evidence of deceit."

Engoron also undercut a common refrain from defendants' that their accountants were responsible for maintaining above-board business practices.

In a section of his ruling titled, "Blame the Accountants," Engoron wrote that, "There is overwhelming evidence … that the buck for being truthful in the supporting data valuations stopped with the Trump Organization, not the accountants."

Donald Trump's Mar-a-Lago Club was worth more than $1.2 billion in 2021 -- roughly double the value listed in Trump's statement of financial condition -- according to defense expert Lawrence Moens.

Describing Mar-a-Lago as a castle nestled on 17.6 acres of waterfront property, Moens said he determined the value by considering nearby properties and adding the total value of the club's 500 memberships, which in 2021 cost $350,000 each.

Between 2011 and 2021, Moens' analysis found that Trump undervalued Mar-a-Lago in his statements of financial condition -- but his analysis appeared to be based on Trump being able to sell the property to an individual to use it as a private residence, which the New York attorney general says Trump is prohibited from doing based on a 2002 deed he signed that would "forever extinguish their right to develop or use the Property for any purpose other than club use."

Judge Engoron only qualified Moens as an expert on the value of residential real estate.

Moens spoke with confidence about his ability to value real estate in Palm Beach, saying that he has sold billions of dollars of real estate since his first sale as a broker in 1982. Asked if any broker has sold more Palm Beach real estate than he has, Moens replied, "They don't exist."

"I am on the front lines everyday of selling properties, and I have a pretty good handle of what is going on currently in the market," Moens said. He later added, "My numbers are usually right."

Moens also put together a seven-minute promotional video about Mar-a-Lago, which was played during his testimony. Set to relaxing music, the video included high-resolution drone shots and dramatic panning shots of the property's amenities. After the video played, Moens highlighted details such as hand-carved stones, gold decorations that cost millions to construct, and other details that required years of work from tradesmen.

"I invited the attorney general's office to come see it anytime. The offer still stands," Moens said. "I will make sure he is not there when you come," he said of Trump.

Engoron appeared attentive to Moen's testimony -- but once Moens left the courtroom, he indicated that he wasn't as concerned about Mar-a-Lago's specific value as he was about whether it was misrepresented.

"I see this case about the documents -- whether the defendants used false documents when transacting business," Engoron said. "I am not trying to figure out what the value is ... I don't necessarily consider it relevant."
