A legal system is a system used to interpret and enforce laws. The most original or commonly known legal system that shaped much of what exists today is known as Common Law. There are three main legal systems of legal procedure; each with its own set of rules called Criminal Procedure Guidelines. These three systems are the adversarial, inquisitorial and popular (mixed) system of criminal procedure (Dammer & Albanese, 2011). The adversarial system is a legal system used in Common Law countries, such as England and the United States, where two lawyers represent their parties' positions before an impartial person or group of people, usually a jury or a judge, who attempt to determine the truth of the case. For many centuries, defendants were prohibited from having legal representation and lawyers rarely appeared for court proceedings; as trials were specifically designed to be an event where the defendant answers the charges in person (Langbein, 2003). Inspired by the Enlightenment period, the adversarial system was developed following a series of treason trials in England, which led to a change in how defendants could defend themselves (Dammer & Albanese, 2011). The transformation from the previous system without lawyers to the current one, dominated by lawyers, occurred over a century, from 1690 to 1780 (Langbein, 2003). In order to investigate and determine the guilt or innocence of the accused an adversarial approach is used. The adversarial system seeks the truth by pitting the prosecution and defense against each other in the hope that competition will reveal it. It is because of the competition that this is often compared to a game or contest where both sides try to win. Primary responsibility...... middle of paper......an_conquest_of_England.html>Douglas D.
