What a statute!
163.3241 Modification or revocation of a development agreement to comply with subsequently enacted state and federal law.—If state or federal laws are enacted after the execution of a development agreement which are applicable to and preclude the parties’ compliance with the terms of a development agreement, such agreement shall be modified or revoked as is necessary to comply with the relevant state or federal laws.
A development agreement is a contract. Per the Contract Clause, the state does not have the authority to modify or revoke a contract. From the U.S. Constitution:
No State shall enter into any Treaty, Alliance, or Confederation; grant Letters of Marque and Reprisal; coin Money; emit Bills of Credit; make any Thing but gold and silver Coin a Tender in Payment of Debts; pass any Bill of Attainder, ex post facto Law, or Law impairing the Obligation of Contracts, or grant any Title of Nobility.
On the face of it, Florida statute 163.3241 would seem to be unconstitutional.
