During the trial, the judge angrily gives one last warning to both Perry and Burger that he would not tolerate any more personal exchanges between them. Nevertheless, when Burger later baits Andy Grant by asking him if Perry had advised him not to answer questions on the stand, the judge gives him another "last warning". In real life, the judge would have sanctioned Burger, possibly finding him in contempt of court.
