If the Florida registry law was applied to you retroactively, then yes the same standard “should” be applied to you. Keep in mind, this ruling is in the 6th Circuit, which includes Michigan, Kentucky, Ohio and Tennessee. A similar lawsuit will need to be started in Florida, and that lawsuit can definitely use the 6th Circuit’s ruling for leverage, which could bring a victory sooner than if there wasn’t a ruling by the 6th.
I don’t know if Florida currently has any ongoing challenges to the registry laws outside of local ordinances there, or if there has been any recent court rulings there. As harsh as the Florida law is, it would seem there would be challenges popping up everywhere.
