I was doing a little googling...because I'm curious like that. I'm not making any allegation WHATSOEVER...but think it will be interesting to listen to the jurors in the coming months. There is a remedy for inappropriate juror misconduct found out AFTER a verdict is rendered. It's called Granting a Motion for New Trial. I need to research and read up....but boy oh boy wouldn't that be a dream come true. Of course, I'm not a lawyer, so we need to ask the attorneys how rare it is that a new trial motion is granted. If ever.

"Granting a motion for a new trial for misconduct discovered after the verdict. Like a motion for mistrial, a motion for a new trial is addressed to the sound discretion of the trial judge, and unless his or her ruling is clearly erroneous or an abuse of discretion, it will not be disturbed. State v. Johnson, 295 N.C. 227 (1978); State v. Sneeden, 274 N.C. 498 (1968)."

Florida Supreme Court leaves it in the trial judges hands on whether or not to set aside the verdict or to claim a mistrial for jury misconduct. IF jury misconduct is revealed, investigated and found true, JP can require a new trial for Casey. According to the document, it's normally the defense who claims jury misconduct, but if there was jury misconduct and it's discovered i.e. a juror with a conscious that comes forward, the jurors can be prosecuted and a mistrial will be declared.
FORGIVE ME IF THIS HAS ALREADY BEEN DISCUSSED. I'm just coming out a my stupor from the verdict reading.
