There’s a standard series of questions a judge will ask a Victim of the Court in a guilty plea situation. “Are you aware of the potential consequences of this plea?” “Are you making this plea of your own free will?” “Are you under any duress to make this plea” - that sort of thing.
Of course no one is going to admit that they are under duress and being forced to plea out “or else”.
Sullivan is now seeking to punish Flynn on this technicality.
Maybe the solution is that Flynn, under duress, pled guilty to being inconsistent in the Lisa Page modified 302 copies. However, he did not plead guilty in the original Pientka 302 forms, which should be the primary evidence, but... alas... are now lost!
