Report to the judge's bailiff or Jury Manager any improper behavior by a fellow juror.
Jurors on a case should refrain from discussing any subject - even if it is not related to the matter being tried - with any lawyer, witness, or party in the case. Such contact may make a new trial necessary.
If it develops during the trial that a juror learns elsewhere of some fact about the case, he/she should inform the court immediately. Do not mention any such matter in the jury room.
Do not try to conduct your own investigation or discover evidence on your own. Cases must be decided only on the basis of evidence admitted in court.
Listen carefully to the instructions given to you by the judge before deliberations. It is your responsibility to accept the judge's instructions about the law and how it is to be applied to the case.
Do not talk to anyone about your deliberations or about the verdict until you are discharged from the case by the judge. After discharge, you may discuss the verdict and the deliberations with anyone, including the media, the lawyers, or your family. But you are NOT obligated to do so.
