A case about alleged misconduct by former state Sen. Jack Latvala is headed back to the Florida Commission on Ethics, after a lawyer for the commission said she could not proceed at the state Division of Administrative Hearings because two witnesses would not testify. Latvala, R-Clearwater, resigned from the Senate in 2017 after the release of a special master’s report about allegations he had sexually harassed Rachel Perrin Rogers, a former Senate aide.
