A defense expert in real estate valuation suggested that a developer's vision could add over a billion dollars of value to a vacant lot.

Frederick Chin, who was qualified as an expert in real estate valuation, argued that Donald Trump used the "as if" investment value of his properties, rather than their current "as is" market value. According to Chin, the "as if" valuation perspective allows a real estate developer to consider the long-term development plans of a property when determining its value.

For example, a vacant lot in the heart of New York City might have a market value of $500 million, according to Chin. A real estate developer who envisions a hotel on the property might see its investment value closer to $2 billion.

Judge Arthur Engoron, who frequently interjected into Chin's testimony, described the approach that resulted in a $1.5 billion difference in the value of a hypothetical vacant lot as a developer's "genius factor."

Donald Trump’s lawyers are seeking to appeal last week’s decision reinstating the gag orders in the former president’s civil fraud trial.

New York’s Appellate Division First Department vacated a temporary stay of the gag orders last week, and Trump’s lawyers are now seeking expedited leave to appeal the decision to New York’s Court of Appeals – the highest court in the New York State system.

Trump’s lawyers requested their application be reviewed by Judge David Friedman, who initially lifted the gag order on Nov. 16 before his decision was vacated by a panel of judges.

“Without expedited review, Petitioners will continue to suffer irreparable injury daily, as they are silenced on matters implicating the appearance of bias and impropriety on the bench during a trial of immense stakes,” Trump’s lawyers wrote in a new filing Monday morning.

In an emergency application for leave to appeal, Trump’s lawyers argued the gag orders “silence the core political speech of the leading Presidential candidate … at the height of President Trump’s campaign.”

Repeating past arguments against the gag order, Trump’s lawyers said the gag orders prohibit necessary speech to highlight the actions of Judge Arthur Engoron’s clerk, which they argue amount to “demonstrable partisan bias on the bench.”

“At stake is a civil defendant’s ability to critique, without fear of reprisal, the court presiding over a bench trial historic both by virtue of the parties thereto and the Attorney General’s novel and open manipulation of the Executive Law to punish her political enemies,” Trump’s lawyers wrote.

Donald Trump's lawyers are scheduled to call three expert witnesses to begin the last full week of their case.

Defense lawyers first plan to call real estate valuation authority Frederick Chin, whose expert report, filed with the court, faults the New York attorney general for taking a "narrow and limited view" of the value of Trump's assets in her complaint against the former president.

Like other defense experts, Chin argues in his report that Trump fairly valued his assets and properly disclosed his valuation approach to his lenders.

After Chin testifies, Trump's lawyers plan to call two experts to testify about Trump's valuation of his Mar-a-Lago property, which has been the subject of bitter debate since the start of the trial. Judge Arthur Engoron, in his pretrial partial summary judgment, already decided that Trump overvalued the property by at least 2,300%, and the defense experts -- Lawrence Moens and John Shubin -- are expected to challenge the judge's findings.

Defense attorneys intend to complete their questioning of the three expert witnesses by Wednesday, when Eric Trump is expected to return to the witness stand.

Judge Engoron again denied a request from the defense to subpoena the Trump Organization's independent monitor for testimony.

Twice this week, Trump's attorneys unsuccessfully sought to call to the stand former judge Barbara Jones, the monitor appointed by Engoron to oversee the Trump Organization's finances after the New York attorney general accused the firm of fraud.

Trump attorney Chris Kise tried for a third time Friday.

"We should be entitled to the benefit of having Judge Jones here to respond to those questions about any ambiguities that might exist in her reports," Kise said.

State attorney Andrew Amer argued against the request, citing Jones' immunity as an agent of the court.

"Your request to subpoena Judge Jones is denied," Engoron said, describing the request as a "dangerous infringement on court immunity."

In her latest report issued to Engoron this week, Jones reported that the Trump Organization was "in compliance" but under "enhanced monitoring."

Court was subsequently adjourned for the day following Engoron's ruling.

The evidentiary portion of former President Trump's civil fraud trial concluded with a combative cross-examination of the state's rebuttal expert.

"The People rest," state attorney Kevin Wallace said after testimony had wrapped up.

During the cross-examination of Cornell accounting professor Eric Lewis, defense attorney Jesus Suarez questioning whether he had "any other real world experience" in accounting other than in the classroom or reviewing documents for court cases. Lewis conceded he did not.

Court will adjourn until Jan. 11, when both sides will present closing arguments after submitting written summations.

Defense attorney Christopher Kise also promised to submit a written argument for a directed verdict that will ask Judge Engoron, for a fifth time, to end the case for lack of evidence. Engoron has not promised to even read such a filing, but said that he "probably" would.

After 11 weeks of heated exchanges, Trump attorney Chris Kise ended on a conciliatory note, thanking the court, the court reporters, and others for their work.

Wallace said it may be their first point of agreement.

Judge Engoron wished everyone happy holidays as he ended the day's proceedings.
