Fla. Stat. § 331.346
Any bonds issued by Space Florida shall be incontestable in the hands of bona fide purchasers or holders for value and shall not be invalid because of any irregularity or defect in the proceedings for the issue and sale thereof. Before the issuance of any bonds, Space Florida shall publish a notice at least once in a newspaper or newspapers published or of general circulation in the appropriate counties in the state, stating the date of adoption of the resolution authorizing such obligations, the amount, maximum rate of interest, and maturity of such obligations, and the purpose in general terms for which such obligations are to be issued, and further stating that no action or proceeding questioning the validity of such obligations or of the proceedings authorizing the issuance thereof, or of any covenants made therein, must be instituted within 20 days after the first publication of such notice, or the validity of such obligations, proceedings, and covenants shall not be thereafter questioned in any court whatsoever. If no such action or proceeding is so instituted within such 20-day period, then the validity of such obligations, proceedings, and covenants shall be conclusive, and all persons or parties whatsoever shall be forever barred from questioning the validity of such obligations, proceedings, or covenants in any court whatsoever. Alternatively, Space Florida may validate its bonds pursuant to chapter 75.
