Judge (or street judge) is a title held by several significant characters in Judge Dredd and other series which appear in the British comics 2000 AD and Judge Dredd Megazine. In the fictional future history of the series, the role of "Judge" combines those of judge and police officer, thus avoiding long legal wrangles by allowing for criminals to be tried and sentenced on the spot. Since they overthrew the U.S. Constitution in 2070, Judges have also held supreme political power in Mega-City One. Collectively they are known as the Justice Department.
