Immediately after jurors are selected for a case, the court must instruct them to turn off their phones and other electronic devices and not to communicate with anyone through any electronic device while they are in the courtroom or while they are deliberating. The court must also instruct them that, while they are serving as jurors, they must not post any information about the case on the Internet or search for any information outside of the courtroom, including on the Internet, to try to learn more about the case.
If jurors are permitted to separate before they are released from jury duty, either during the trial or after the case is submitted to them, the court must instruct them that it is their duty not to communicate with, or permit themselves to be addressed by, any other person about any subject relating to the case.
