An attorney should instruct his/her client and the witnesses he plans to call about the proprieties of their Court appearance. The lawyer should explain that at no time are they to approach or communicate with a juror or Judge. An attorney should also instruct his/her clients and witnesses that they are to remain outside the bar until their case is called or they are called to testify. A violation of this Rule may not only result in a mistrial, but may also result in contempt proceedings and/or assessment of costs (including juror expense and attorney's fees) to the adverse party for the aborted trial.
