ex-post facto.
Ex-post facto applies only in criminal cases. This is a "civil" execution in the State of FL. When tax hikes were passed in the summer of 1993, they were for instance made retroactive to Jan. 1, for the convenience of tax collectors. And it was legal. Similary, the GWB tax cuts of 2001 were also retroactive: hence $500 checks were issued in the fall of 2001 to many families.
Disagree. A state can't pass ex-post facto laws either. Clearly stated in the Constitution. Ex-post facto means after the fact.
