Implementation of HAVANA Act of 2021, 19 April 2024
The Havana Act has a new final rule. Most interesting is the definition of “other incident”:
The definition of “other incident” is a new onset of physical manifestations that cannot otherwise be readily explained and that is designated under 22 U.S.C. 2680b. The Department will review available information on the reported incident. If a physician does not indicate that there is a credible alternative explanation for the individual’s symptoms, and if the information the Department has regarding the incident does not provide a credible alternative explanation for the incident, that incident will be recommended for designation. Incidents for which an alternative explanation has been identified will not be recommended for designation. For incidents affecting employees or dependents who are not under the security responsibility of the Secretary of State, the Department will determine whether to designate such incidents.
The problem with the Havana Act in general is that it assumes that attacks are time-limited.
