True, however, I believe this is an extenuating case involving fraud, threats, lying, set up, etc. How many court cases have been changed from normal circumstances to give justice to an injustice done to a citizen.
If a defendant takes a plea deal and pleads guilty and goes to jail and later it is found there was fraud in the evidence does the case and charges not over-turned?
That I don’t know only that I’ve read and have been told that it is very rare and difficult to get a case over turned once a guilty plea was entered. I’ve read of some prisoners who were told to plea guilty by bad lawyers or pled guilty after falsely confessing to a crime after undue duress from cops without a lawyer present. They had their cases over turned, though some of them spent decades in prison first.
It might be harder for Trump to issue a pardon to Flynn in such a case though he could still do a commutation of sentence.
