Casey Anthony trial Judge Belvin Perry said Monday that tactics employed by lawyers on both sides could force him to exclude some witnesses, a move that would open the door to a mistrial.

Perry criticized the attorneys for gamemanship, particularly for defense attorney Jose Baez using witnesses who offered testimony that was not in a report witnesses are required to submit before they take the stand. If that continues, Perry said, he might exclude some witnesses. That could allow Anthony's lawyers to get a mistrial on the grounds that she was not fairly represented.

The judge also warned that the lawyers could be subject to punishment for their conduct in the case.

Yes, there have been gamesmanship in this particular case and it is quite evident there is a friction between attorneys, Perry said. That is something I guess the Florida bar will deal with. And at the conclusion of this trial this court will deal with violations which may or may not have occurred.
