Final answer:
The adversary system in the American court designates that the defense and prosecution do not decide the defendant's guilt; instead, it is the jury's responsibility to determine guilt after careful deliberation of the evidence presented during the trial.
Step-by-step explanation:
The model that makes it clear that it is not the job of the defense or prosecution to decide guilt of the defendant is the adversary system used in the American court system. In a trial, the prosecutor's job is to prove the accused's guilt beyond a reasonable doubt, while the defense's job is to challenge the prosecution's evidence and present any evidence that supports the defendant's innocence.
It is the jury's responsibility to determine guilt, based on the evidence and arguments presented by both parties. In some cases where there is no jury, it is the judge who determines the guilt or innocence of the defendant.
The Sixth Amendment ensures the right to a trial by an impartial jury, which protects individuals from the potential bias of the legal system. The jury hears the evidence and deliberates to decide the verdict. The judge oversees the legal proceedings, ensuring they are conducted fairly, and decides on the penalty if a defendant is found guilty.
