A juror’s tweets have caused the murder conviction of a death row inmate to be overturned by a court in the US.
Arkansas Supreme Court judges said it was inappropriate for a juror to have posted his musings online.
They have asked a panel to consider whether jurors’ access to mobile phones should be limited during trials.
The review coincides with a warning from England and Wales’s Lord Chief Justice that the internet threatens the integrity of trials.
