This guidance explains the current general practice of the Department in making criminal prosecutive and other decisions after giving consideration to the criteria described above, as well as any other criteria that are relevant to the exercise of criminal prosecutorial discretion in a particular case. This discussion is an expression of, and in no way departs from, the long tradition of exercising prosecutorial discretion. The decision to prosecute "generally rests entirely in [the prosecutor's] discretion." Bordenkircher v. Haves , 434 . 357, 364 (1978). (5) This discretion is especially firmly held by the criminal prosecutor. (6) The criteria set forth above are intended only as internal guidance to Department of Justice attorneys. They are not intended to, do not, and may not be relied upon to create a right or benefit, substantive or procedural, enforceable at law by a party to litigation with the United States, nor do they in any way limit the lawful litigative prerogatives, including civil enforcement actions, of the Department of Justice or the Environmental Protection Agency. They are provided to guide the effective use of limited enforcement resources, and do not derive from, find their basis in, nor constitute any legal requirement, whether constitutional, statutory, or otherwise, to forego or modify any enforcement action or the use of any evidentiary material. See Principles of Federal Prosecution (. Dept. of Justice, 1980) p. 4; United States Attorneys' Manual (. Dept. of Justice, 1986) 1-.
