Mazars statement against his? It was in the contract that Trump signed that he was to turn over all records relating to those properties which includes appraisals.
It wasnt an error in square footage. It was willfully misleading. Trump made public statements at the time it was built with the correct square footage. You can say he forgot over time but this is a man who claims to have one of the greatest memories of all time. If he was a dentist maybe I buy that but he is literally a property developer. I find it hard to believe that a real estate developer forgets the square footage of his own apartment 5 years after he had it built. They showed in the trial that they had no interest in correcting the record when notified. Weaselberg had the correct information in his filing cabinet right outside his office. Never even bothered to look it up after notified. Only after the claim went public did they do anything about it.

Here is the ruling by the Judge. Its very thorough. I suggest you read it because it goes witness by witness with the important details. This wasnt accounting errors or differences of opinion. This was a practice and pattern of deceitful accounting.
