There’s this sticky little thing called an “ex post facto” law, that is also forbidden under the Constitution.
Great point!!!
Ex Post Facto refers to criminal law, not simple legal definitions or standards. The Ex Post Facto ruling on Canal Zone citizenship is what gave McCain ‘natural born citizenship’ status re 8 U.S.C. §1403 which retroactively recognized canal zone citizenship. (the bill, passed in 1952 was made retroactive to Feb, 1904)
Not under all circumstances, especially when someone is deriving a benefit & not being punished as a result of the ex post facto law.
Clinton aleady set the precedent with his retroactive tax increases
