When I served on a jury, the judge had us leave the courtroom multiple times. Once the trial was over, the judge told us what was being discussed when we left the room, and the reason the information had been excluded from testimony during the trial.
Had the DA tried to introduce this information while the jury was in the room it probably would have made it more difficult for us to come to the same verdict. I imagine that if the DA tried to do this often enough, it could lead to a mistrial and possible disciplinary action.
"...in excess of $50k." This language is defined by the Florida Wrongful Death statute and means at least $50,001 but can be much more.
