In Law & Order: SVU, what was the 'lie' that Casey Novak told to a judge that led to her being fired/disbarred/imprisoned? What exactly was the consequence? How did it come out that she had lied?
She basically violates due process by breaking the Brady rules, which are rules governing the disclosure of all information to all parties (Such as not prosecuting a witness in exchange for testimony). She does this to convict a cop rapist.
Initially she is told that she is facing either censure or being disbarred, and when she left the show they settled on disbarred. This is contradicted, however, a few seasons later when she returns to the show and it was reduced to a censure.
