The adversarial system or adversary system is a legal system used in the common law countries where two advocates represent their parties' positions before an impartial person or group of people, usually a jury or judge, who attempt to determine the truth of the case. It is in contrast to the inquisitorial system used in some civil law systems where a judge or group of judges investigates the case. The adversarial system is the two-sided structure under which criminal trial courts operate that pits the prosecution against the defense. Justice is done when the most effective adversary is able to convince the judge or jury that his or her perspective on the case is the correct one. This video is targeted to blind users.
