The closest precedent is for situations like when a woman tries to drop charges against an abusive husband/boyfriend, and the state decides to prosecute anyways. Except even in this case, the state, i.e. the federal government, has dropped the charges. Sullivan will lose in the end, but he's going to try every dirty trick he can to extend Flynn's suffering. This isn't about justice, it's about spite, it always was.
What makes it even more egregious is the fact that with all the information recently released about how the FBI agents were operating, even if they could try to prosecute the case, they would never win. The judge doesn't care about this information, because he's in on it. He's playing the part he was meant to play long before Flynn got framed. Sullivan wasn't a random judge, he was chosen specifically because they knew he was corrupt.
