True. The American Justice system is indeed an adversarial system. This means that it is a system where two advocates represent their parties' positions before an impartial person or group of people, usually a judge or jury, who attempt to determine the truth of the case. The prosecutor represents the government in cases involving criminal law, while in civil law cases, a private party (often called a "plaintiff") files a lawsuit against another party (the "defendant"). Each side presents its arguments and evidence, and the judge or jury decides based on this presentation. This is in contrast to an inquisitorial system, where the judge plays a more active role in investigating the facts of the case.
