JM 9-10.140
The standards governing the determination to be reached in cases under this Chapter include fairness, national consistency, adherence to statutory requirements, and law-enforcement objectives.
A. Fairness requires all reviewers to evaluate each case on its own merits and on its own terms. As with all other actions taken in the course of Federal prosecutions, bias for or against an individual based upon characteristics such as race or ethnic origin play no role in any recommendation or decision as to whether to seek the death penalty.
B. National consistency requires treating similar cases similarly, when the only material difference is the location of the crime. Reviewers in each district are understandably most familiar with local norms or practice in their district and State, but reviewers must also take care to contextualize a given case within national norms or practice. For this reason, the multi-tier process used to make determinations in this Chapter is carefully designed to provide reviewers with access to the national decision-making context, and thereby, to reduce disparities across districts.
C. In determining whether it is appropriate to seek the death penalty, the United States Attorney or Assistant Attorney General, the Capital Review Committee, the Deputy Attorney General, and the Attorney General will determine whether the applicable statutory aggravating factors and any non-statutory aggravating factors sufficiently outweigh the applicable mitigating factors to justify a sentence of death or, in the absence of any mitigating factors, whether the aggravating factors themselves are sufficient to justify a sentence of death. Reviewers are to resolve ambiguity as to the presence or strength of aggravating or mitigating factors in favor of the defendant. The analysis employed in weighing the aggravating and mitigating factors should be qualitative, not quantitative: a sufficiently strong aggravating factor may outweigh several mitigating factors, and a sufficiently strong mitigating factor may outweigh several aggravating factors. Reviewers may accord weak aggravating or mitigating factors little or no weight. Finally, there must be substantial, admissible, and reliable evidence of the aggravating factors.
D. In deciding whether it is appropriate to seek the death penalty, the United States Attorney or Assistant Attorney General, the Capital Review Committee, the Deputy Attorney General, and the Attorney General may consider any legitimate law enforcement or prosecutorial reason that weighs for or against seeking the death penalty. Those considerations may include, but are not limited to:
(1) The strength and nature of the evidence;
(2) The relative roles in the offense of defendants in jointly undertaken criminal activity;
(3) Whether the offense was intended to obstruct justice or was otherwise motivated by the victim's cooperation with law enforcement or the belief that the victim was cooperating with law enforcement;
(4) Whether the offense was committed to retaliate against a third-party for cooperating with law enforcement or against a third party believed to be cooperating with law enforcement;
(5) Whether the victim engaged in criminal activity that was a relevant circumstance of the offense;
(6) Whether a defendant engaged in criminal activity for which he had not been held accountable;
(7) Whether the defendant is already serving a substantial sentence such that an additional sentence of incarceration would have little punitive impact;
(8) Whether the defendant has a history of infractions or offenses while incarcerated; and
(9) Whether the defendant has accepted responsibility for his conduct as demonstrated by his willingness to plead guilty and accept a life or near-life sentence without the possibility of release.
