“Brady materials” or “Brady evidence” is exculpatory evidence or witness-impeachment evidence a prosecutor is obligated to share with the defense.

It’s important to note, however, that a conviction is NOT necessarily and certainly not automatically reversed by the revelation of Brady evidence. I do not know if the same can be said over a “guilty” plea. In this case it would not result in an automatic exoneration for Flynn, though it would likely lead there after a few more hearings.

You are correct. It is up to the judge, based on the materials withheld.

FTA: Sullivan also noted during the hearing that the Brady order takes precedence over the plea agreement.

Based on the info above, I believe that the judge could overturn the plea agreement.
