A Judge and Jury in the US Trials
A judge convening a case for trial before a jury, his or her mission is to manage , facilitate, and oversee a process that will render an outcome based on a fair and impartial assessment of the evidence in the case.
A judge must to make jurors understand that they are like deputized judges sworn to fairness.
The judge is responsible for ensuring the integrity of the proceedings by making sure that the attorneys perform properly within the boundaries of their function.
The representatives of both sides (the prosecution and the defence) participate in the selection of the member of the board of adjudicators.
The judge rules on matters before and during the trial that allow or disallow the jury to consider evidence proposed by the attorneys. In that regard, the judge gives the members of the jury instructions at the beginning, during, and at the end of the trial intended to guide them in the process of fairly considering the testimony, documents, and other evidence in the case. The judge, by his or her example, motivates the jury to consider matters neutrally while they await the completion of the trial.
The relationship that often develops between a jury and its presiding judge is one of trust. The jury trusts the judge to give it what it needs by way of the law and guidance on how to evaluate the case fairly. The judge entrusts the jury with the ultimate responsibility of administering justice.
