When the defense attorney informs E.A.D.A. Jack McCoy that her client would be pleading an affirmative defense of Postpartum Psychosis, McCoy scoffs: "It didn't work with Andrea Yates in Texas and she drowned five children." The defense attorney replies: "In case you haven't been keeping up with your law journal, Andrea Yates is getting a new trial." The reason Andrea Yates received a new trial? Dr. Park Dietz, a psychiatrist who testified for the prosecution, erroneously stated that he had worked as a consultant on 'Law & Order' for an episode that bore a striking similarity to the Andrea Yates case. No such episode existed and that got Yates her new trial.
