(7) In any trial or other proceeding brought by the enforcing authority pursuant to this part, statements having circumstantial guarantees of trustworthiness may be used to supplement and explain other evidence and shall not be excluded as hearsay evidence, even though the declarant is available as a witness, if the trier of fact determines that:
(a) The statement is offered as evidence of a material fact;
(b) The statement is more probative on the point for which it is offered than any other evidence which the proponent can procure through reasonable efforts; and
(c) The general purpose of the Florida Rules of Evidence and the interests of justice will be best served by the admission of such statement into evidence.
However, a statement may not be admitted hereunder unless the proponent of it makes known to the adverse party, sufficiently in advance of the trial or proceeding to provide the adverse party with a fair opportunity to prepare to meet it, the proponent's intention to offer the statement and the particulars of it, including the name and address of the declarant.
