Justice Manual § 9-27.240

In determining whether prosecution should be declined because the person is subject to effective prosecution in another jurisdiction, the attorney for the government should weigh all relevant considerations, including:

The strength of the other jurisdiction's interest in prosecution;

The other jurisdiction's ability and willingness to prosecute effectively; and

The probable sentence or other consequences if the person is convicted in the other jurisdiction.

When declining prosecution, or reviewing whether federal prosecution should be initiated, the attorney for the government should: (1) consider whether to discuss the matter under review with state, local, territorial, or tribal law enforcement authorities for further investigation or prosecution; and (2) coordinate with those authorities as appropriate. The attorney for the government should be especially aware of the need to coordinate with state, local, territorial, and tribal law enforcement authorities, and shall do so as permitted by law, when declining a matter that involves an ongoing threat or relates to acts of violence or abuse against vulnerable victims, including minors. The attorney for the government should document these coordination efforts, where undertaken, when federal prosecution is declined.

Comment. In many instances, it may be possible to prosecute criminal conduct in more than one jurisdiction. Although there may be instances in which a federal prosecutor may wish to consider deferring to prosecution in another federal district, or to another government, in most instances the choice will probably be between federal prosecution and prosecution by state or local authorities. The factors listed in JM 9-27.240 are illustrative only, and the attorney for the government should also consider any others that appear relevant to his/her particular case.

The Strength of the Jurisdiction's Interest. The attorney for the government should consider the relative international, federal, state, territorial, and tribal interests with regard to the alleged criminal conduct. Some offenses, even though in violation of federal law, are of particularly strong interest to the authorities of the jurisdiction in which they occur (e.g., local, state, or foreign), either because of the nature of the offense, the identity of the offender or victim, the fact that the investigation was conducted primarily by foreign, state, or local investigators, or some other circumstance. Whatever the reason, when it appears that the federal interest in prosecution is less substantial than the interest of local, state, or foreign authorities, consideration should be given to referring the case to those authorities rather than commencing or recommending a federal prosecution.

Ability and Willingness to Prosecute Effectively.In assessing the likelihood of effective prosecution in another jurisdiction, the attorney for the government should also consider the intent of the authorities in that jurisdiction and whether that jurisdiction has the prosecutorial and judicial resources that are necessary to undertake prosecution promptly and effectively. Other relevant factors might be legal or evidentiary problems that might attend prosecution in the other jurisdiction. In addition, the federal prosecutor should be alert to any local conditions, attitudes, relationships, or other circumstances that might cast doubt on the likelihood of the other authorities conducting a thorough and successful prosecution.

Probable Sentence Upon Conviction. The ultimate measure of the potential for effective prosecution in another jurisdiction is the sentence, or other consequence, that is likely to be imposed if the person is convicted. In considering this factor, the attorney for the government should bear in mind not only the statutory penalties in the jurisdiction and sentencing patterns in similar cases, but also, the particular characteristics of the offense or of the offender that might be relevant to sentencing. He/she should also be alert to the possibility that a conviction under another jurisdiction’s laws may, in some cases, result in collateral consequences for the defendant, such as disbarment, that might not follow upon a conviction under federal law.
