Relating to restrictions on the use of certain ad valorem tax revenue for the payment of public securities.

SB 2519 restricts how property tax revenue (ad valorem taxes) can fund public bonds or securities. It defines "materially deviate" as significant changes to approved tax purposes, such as cost increases over 33%, scope reductions, or altered financing structures. Property owners can seek an injunction to stop tax collection if a taxing unit (like a city or county) deviates from the original purpose, with refunds and legal fees if they win. The law applies to tax elections adopted after its effective date, preventing revenue from property tax votes from being redirected to pay bond debts.
