    You don't have it quite right. You cannot be put on trial today for something you did when what you did was legal at the time but is illegal today.

    That is the principle that criminal laws cannot be retroactive.

    What you state is a fallacy. You can still be put on trial if what you did was illegal when you did it unless the law the reversed it had a provision in it to make the reversal retro-active.

    There are still lots of people in jail/prison for marijuana violations even in states that have legalized it (in addition to those in federal prison where it's still illegal regardless of state action).

    You're thinking of "ex post facto", though that isn't as you state.  Try looking it up.

    Actually the way you put it is wrong.  If it was legal when you did it, you can't be prosecuted under a law made later.

    If you did something that was illegal when you did it but has since been made legal, the same principle says you're still guilty.  But we usually release people in that case.  Like if you're in jail for possession of marijuana and then your state legalizes it.
