The state can take it away….but there does not appear to be a legal path forward to require TWDC to pay for the services that are now provided by the special district. The real rub here is Disney was paying more than their fair share in taxes in exchange for a level of control over the quality of services provided. If you take away the control you also take away the payments. The debate is not whether the state can legally dissolve a special district.
The only way to do that is to create a special district. So if nothing happens, then TWDC will pay the same rate in property taxes I pay.
