The Committee on Court Administration and Case Management suggests that jury instructions should include specific prohibitions against Twitter, among other things. The recent proposal was driven by increasing juror misfeasance, in the form of using smartphones to do research or communicate with others during jury proceedings.
The model instructions suggest instructing jurors that during trial they should not use any electronic resources to research the case, nor should they use any social media to discuss the case with others.
During deliberations, the instructions prohibit communication by any means, including the use of smartphones and electronic media. Hopefully, more explicit directions will reduce juror’s usage of the devices and social media.
