Communications between a patient and a psychiatrist, as defined in s. 394.455, shall be held confidential and shall not be disclosed except upon the request of the patient or the patient’s legal representative. Provision of psychiatric records and reports shall be governed by s. 456.057. Notwithstanding any other provision of this section or s. 90.503, where:
(1) A patient is engaged in a treatment relationship with a psychiatrist;
(2) Such patient has made an actual threat to physically harm an identifiable victim or victims; and
(3) The treating psychiatrist makes a clinical judgment that the patient has the apparent capability to commit such an act and that it is more likely than not that in the near future the patient will carry out that threat,
the psychiatrist may disclose patient communications to the extent necessary to warn any potential victim or to communicate the threat to a law enforcement agency. No civil or criminal action shall be instituted, and there shall be no liability on account of disclosure of otherwise confidential communications by a psychiatrist in disclosing a threat pursuant to this section.
