What's going on here is the judge is demonstrating either a profound ignorance of Florida law and the housing market, or is willfully and maliciously weaponizing New York law against Florida law, imposing an interstate financial liability on someone for being subject to another state's policies. Assessed property values in Florida are wildly out of step and far below market value rates, as a result of intentional policies the florida legislature passed to cap assessed values and thus spare homeowners the ballooning property taxes that would come with the hot housing market. They purposefully keep their taxes low- back in 1995 Florida passed the Save Our Homes Amendment which caps assessed value increase per year at 3% or the CPI (10% max for non-homesteads), whichever is lower. As well as other clauses I probably don't even know about, seeing as I'm no master of Florida law
New York by contrast limits the
property taxes rather than the assessed value, putting a limit on local governments to raise their rates.
The judge is taking a valuation of a property that's obviously worth $350+ million on the market, and could plausibly be closer to the $750 billion cited by Trump, and saying Trump is committing fraud and liable because his valuation isn't consistent with the Florida assessment. If Trump had cited the property as actually being worth $18 million like the judge said, he'd be committing fraud in Florida because that's obviously fucking wrong. Thus the judge has created a catch-22: Either Trump, a florida resident, can obey Florida law and violate New York law, or he can obey New York law and violate Florida law. Imposing penalties on someone for a property that is plainly not in the judge's jurisdiction.
I sincerely doubt this judge got their position in life while being a mouth breathing moron, so its just a political hitjob dressed up under a paper thin pretense.
