ADVERSARY SYSTEM
adversary system.A procedural system, such as the Anglo-American legal system, involving
active and unhin-dered parties contesting with each other to put forth a case before an independent
decision-maker. — Also termed adversary procedure; (in criminal cases) accusatorial system,
accusatory procedure. Cf. INQUISITORIAL SYSTEM.
“The term adversary system sometimes characterizes an entire legal process, and sometimes
it refers only to criminal procedure. In the latter instance, it is often used interchangeably with an
old expression of continental European origin, ‘accusatorial procedure,’ and is juxtaposed to the
‘inquisitorial,’ or ‘nonadversary,’ process. There is no precise understanding, however, of the
institutions and arrangements denoted by these expressions.” Mirjan Damaska, “Adversary
Procedure,” in 1 Encyclopedia of Crime and Justice 24, 24–25 (Sanford H. Kadish ed., 1983). [Blacks Law 8th]
