An adversarial system is a legal framework where two opposing parties present their cases to an impartial judge or jury. Each side, typically represented by lawyers, aims to prove their argument while challenging the other side's claims. This system is designed to ensure that all evidence and arguments are thoroughly examined before a decision is made. In many countries, including the United States, the adversarial system is a fundamental part of the judicial process. It contrasts with an inquisitorial system, where the judge plays a more active role in investigating the case. The goal of the adversarial approach is to achieve a fair and just outcome through competition between the parties involved.
