Justice Manual § 9-27.120

In carrying out criminal law enforcement responsibilities, each Department of Justice attorney should be guided by these principles, and each United States Attorney and each Assistant Attorney General should ensure that such principles are communicated to the attorneys who exercise prosecutorial responsibility within his/her office or under his/her direction or supervision. Prosecutors should further refer to the Attorney General’s memoranda—General Department Policies Regarding Charging, Pleas, and Sentencing and Additional Department Policies Regarding Charging, Pleas, and Sentencing in Drug Cases—for additional background and guidance.

Comment. It is expected that each federal prosecutor will be guided by these principles in carrying out his/her criminal law enforcement responsibilities unless a modification of, or departure from, these principles has been authorized pursuant to JM 9-27.140. However, it is not intended that reference to these principles will require a particular prosecutorial decision in any given case. Rather, these principles are set forth solely for the purpose of assisting attorneys for the government in determining how best to exercise their authority in the performance of their duties.
