This document discusses the English criminal justice system. It explains that the system is adversarial, where the prosecution and defense argue their cases against each other. Offenses are classified as summary, indictable, or triable-either-way, with the most serious crimes tried at the Crown Court. The criminal court system includes magistrates courts for less serious crimes and Crown Courts for more serious indictable offenses. Factors like the severity of the crime determine whether a case is heard at the magistrates or Crown Court level.
