No, and certainly not in all cases. For example, United States Sentencing Guidelines Section 5K1.1 permits a downward guideline departure for cooperating defendants who provide “substantial assistance” in the investigation or prosecution of another person. Under the U.S. Sentencing Guidelines, a departure under Section 5K1.1 is not a matter of course, the federal government must file a specific motion in order for the district court to grant the downward departure.

While the federal government’s motion is a requirement for a departure under Section 5K1.1, the provision of substantial assistance can still be used for other types of sentencing relief. For example, without a § 5K1.1 motion, courts have the discretion to consider a defendant’s cooperation as a mitigating factor in their decision. While mitigation alone cannot reduce a sentence below its applicable mandatory minimum, this form of sentencing relief is still a key option for many federal defendants.

Another important aspect of cooperation is the distinction between truthfulness and completeness. In order to qualify for a departure under Section 5K1.1, the information provided by the defendant must be both truthful and complete. While information that is deemed incomplete may not meet the strict standard for substantial assistance (and thus not justify a § 5K1.1 departure), this fact does not necessarily compromise the defendant’s overall credibility or the factual accuracy of the information that was provided.

Providing information that is deemed incomplete does not automatically eliminate all forms of mitigation at sentencing. If a defendant has been truthful and has not engaged in obstructive conduct, then their cooperation, even if not deemed “substantial” under the § 5K1.1 standard, may still warrant consideration as a mitigating factor during sentencing.

As a result, when facing the possibility of incomplete cooperation at the sentencing stage, a federal defendant’s priorities are twofold. First, they must still show their eligibility for any cooperation-related relief for which they qualify. But, if a successful argument for cooperation-related relief is not available, then the priority shifts. Instead of demonstrating eligibility for a § 5K1.1 departure, defendants and their lawyers must work to ensure that judges are not falsely relying on the prospect of incomplete cooperation to deny any applicable sentencing relief.

How do prosecutors and courts assess cooperation that is truthful but incomplete?

Prosecutors generally assess the value of information provided by cooperating defendants based on four primary criteria. Most importantly, prosecutors consider whether the information is new, credible, useful, and verifiable. While these criteria describe the factual conditions for granting substantial assistance, prosecutors must also make more subjective judgments. Prosecutors will carefully consider the utility of the information provided by a defendant, and whether the defendant’s cooperation is useful in any significant respect. For example, prosecutors may heavily value information that leads to the arrest, investigation, or conviction of another criminal.

While prosecutors may offer a § 5K1.1 motion, the decision to actually grant a downward departure rests with the sentencing court. Similarly, the extent of a downward departure (if granted) is determined by the court as well. When evaluating cooperation for purposes of sentencing under Section 5K1.1, sentencing courts consider “the significance, usefulness, truthfulness, completeness, and reliability of the information, the nature, extent, and timeliness of the defendant’s assistance, and any injury suffered, or any danger or risk of injury to the defendant or his family resulting from his assistance.”

The government’s assessment of a defendant’s cooperation is generally given substantial weight under the commentary to the U.S. Sentencing Guidelines. It states that, while “When such provisions, however, are made part of a plea agreement and constitute the basis of the bargain, the court can make its own independent determination regarding whether to depart downward or apply a three-level reduction for acceptance of responsibility if it determines that the Government’s refusal to offer such a motion is attributable to bad faith.” the commentary “Upon motion of the government stating that the defendant has provided substantial assistance in the investigation or prosecution of another person who has committed an offense, a sentence that is below the otherwise applicable guideline range may be appropriate.... Substantial weight should be given to the government's evaluation of the extent of the defendant's assistance, particularly where the extent and value of the assistance are difficult to ascertain.”

As this shows, while both the prosecution and the court play significant roles in determining whether the provided information is sufficient to qualify as substantial assistance, the government’s views carry particular weight. This creates a high burden of proof, which federal prosecutors and sentencing judges can use to defend against any and all requests for a downward departure.

When dealing with federal prosecutors and sentencing judges, it is essential to work with an experienced attorney to ensure your cooperation efforts are fully understood, and recognized, at sentencing. If the prospect of incomplete cooperation threatens to affect your eligibility for a § 5K1.1 departure, then it may still be possible to prove that your cooperation efforts fully warrant the relief you deserve.

Most first calls to Spodek Law Group are not from the person under investigation. They come from a mother, a husband, a sister, holding a phone and frightened.

Which government motions can matter when §5K1.1 relief fails or assistance comes later?

While 18 U.S.C. § 3553(e) is often listed in the same context as § 5K1.1 of the Sentencing Guidelines, it is a separate provision. Specifically, § 3553(e) states that for a court to impose punishment below the statutory minimum for any offense, the government must first file a motion to this effect. Once a § 3553(e) motion is filed, the district court has the authority to impose a sentence that falls below the applicable mandatory minimum sentence, if a motion to impose a sentence below the minimum is deemed appropriate in the case at hand. As a result, if a federal crime carries a mandatory minimum sentence, a § 5K1.1 departure alone may not be enough to provide relief. In these cases, it will be critical to persuade the government to file a § 3553(e) motion as well.

With that said, neither 18 U.S.C. § 3553(e) nor § 5K1.1 permit the district court to compel the government to file either motion if it finds it inappropriate. However, this is not the end of the road for defendants who have fully cooperatively. In all cases, a prosecutor’s refusal to file a § 3553(e) or § 5K1.1 motion may be reviewable, and, if review demonstrates unconstitutional motives, the government’s failure to seek such a motion can be viewed as a prosecutorial overreach.

Finally, it is also important to distinguish between cooperation provided before or after sentencing. While cooperation that precedes sentencing may justify relief under Section 5K1.1 of the U.S. Sentencing Guidelines, Rule 35(b) is expressly reserved for cases in which the defendant provided substantial assistance following sentencing. When a defendant provided substantial assistance following sentencing, then Rule 35(b)(1) permits the government to move within one year after sentencing to reduce the sentence. Again, without such a motion, the court will not have the authority to reduce a sentence based on the defendant’s post-sentencing cooperation efforts, and the prosecution’s failure to file a Rule 35(b) motion may have significant implications for any attempt to seek relief from the sentencing court.

Rule 35(b) creates yet another scenario that requires specific, timely action. If a criminal defendant has received a prison sentence but still has information that could be of use in federal investigations or prosecutions, then Rule 35(b) permits the government to file a motion to reduce the sentence. Rule 35(b) requires a motion to reduce the sentence and, similar to § 5K1.1 and § 3553(e), it is important to ensure that your attorney is actively engaged in facilitating the government’s review of these options.

What can proffer terms or negotiated plea concessions change after cooperation breaks down?

A proffer agreement, while primarily serving as a tool for facilitating negotiations, also provides substantial protections to defendants. Specifically, a proffer agreement typically prohibits the government from introducing incriminating statements made during the proffer into evidence in the government’s case-in-chief. However, these protections are far from absolute.

For example, while information provided during a proffer generally cannot be used against the defendant as direct evidence, it can still be used to generate investigative leads. In many cases, any information that appears to be incriminating will lead the federal government to investigate other avenues for gathering evidence, many of which are not protected by the proffer agreement. Thus, while a direct admission made during a proffer might not be admissible, evidence derived from an admission made during a proffer session is generally admissible.

Proffer agreements can also permit the government to use statements against the defendant for the limited purpose of impeachment. If a defendant makes incriminating statements during a proffer session but later provides conflicting testimony during a federal trial, the government can likely use the statements made during the proffer to impeach the defendant’s credibility. While this means the statements will not serve as the primary evidence of guilt, this can still have detrimental effects on a defendant’s ability to present a convincing defense.

Finally, when cooperating defendants are accused of providing false or misleading information, this can lead to prosecution, even if the defendant believed the information was truthful at the time it was provided. As a result, cooperating defendants who were not thoroughly vetted can lead to federal false-statement prosecutions under 18 U.S.C. § 1001. In addition to being considered a breach of the defendant’s cooperation agreement, federal charges for making false statements generally carry a maximum of five years’ imprisonment, but certain circumstances specified in 18 U.S.C. § 1001 increase the maximum to eight years. This can drastically increase federal criminal exposure for defendants, and it places a heightened premium on ensuring that cooperating defendants are thoroughly vetted.
