Sealed Filings and Cooperation: Keeping Your Role Confidential
The Seal Is Not the Shield
Cooperation in a federal criminal case produces a record. The question, for most clients who sit across from us for the first time, is not whether to cooperate but whether the cooperation can remain invisible to the people most motivated to discover it. The answer is more conditional than comfortable.
The federal judiciary has spent the better part of two decades attempting to conceal which defendants assist the government and which do not. The effort is genuine, and the incompleteness is where the danger concentrates.
The Docket as Weapon
Before the Judicial Conference intervened, a federal docket was a map. A sealed motion for downward departure, visible as a gap in the docket numbering, announced cooperation as clearly as if someone had written it in the margin. Inmates and their associates did not need access to the documents themselves; the shape of the record was sufficient. A plea agreement filed on a Tuesday, a sealed entry on a Wednesday, a sentencing memorandum three weeks later with a conspicuous gap in the numbering: the pattern was legible to anyone who knew what to look for.
A website that launched in 2004 industrialized this process. Court filings downloaded from PACER were aggregated and published alongside photographs and accusations. Federal prosecutors described the site’s purpose as the encouragement of violence. Federal judges from Minnesota to Utah warned their colleagues that witnesses in their courtrooms were being profiled online.
The Federal Judicial Center surveyed judges, prosecutors, public defenders, and probation officers to measure the scope of retaliation. Respondents identified hundreds of cases in which cooperators had been threatened, assaulted, or killed over a three-year period. The FJC survey’s authors acknowledged the figure was likely an undercount.
The response was not swift. The Department of Justice initially proposed removing all plea agreements from electronic public access. The Conference declined. A Fordham Law School conference in 2010 produced no consensus on a single best practice. Three joint committees in 2014 asked judges to stop using cooperators’ names in published opinions. It was not until 2016 that the Committee on Court Administration and Case Management issued formal guidance, and even then, the guidance was interim.
The Sealed Supplement
In districts that follow the CACM recommendation, every plea agreement in every felony case contains a sealed supplement. If the defendant cooperated, the supplement contains the cooperation agreement. If the defendant did not cooperate, the supplement states that no cooperation agreement exists. The supplement is sealed in either case. The result, in theory, is that no outside observer can distinguish a cooperator’s docket from a non-cooperator’s by the presence or absence of a sealed filing.
The District of Kansas illustrates one of the more careful implementations. A Restricted Document Folder is created in every felony case at the moment the case is opened. The folder’s existence on the docket does not indicate cooperation. Counsel for the defendant and the government have access; counsel for co-defendants do not. Documents containing cooperation information are not filed through the electronic system at all but emailed to chambers.
This is the mechanism that matters most, and it is not universal. Over a third of federal districts had adopted some form of uniform sealing by the time the CACM guidance was issued. The remaining districts operate under, if we are being precise, a patchwork of local rules, standing orders, and informal practices that range from rigorous to negligent. In certain districts in the Ninth Circuit, plea agreements remain available on PACER, and a motion to seal is both required and, once granted, a visible signal to anyone paying attention. Whether the court intended this outcome or merely failed to prevent it is a question worth considering.
What a 5K1.1 Motion Discloses
Under Section 5K1.1 of the Sentencing Guidelines, the government may move for a downward departure if a defendant has provided substantial assistance in the investigation or prosecution of another person. The motion can only be filed by the prosecution. Defense counsel cannot compel it. The court cannot grant the departure without it.
The motion, where it exists on a docket, is informative. It identifies the defendant as someone who assisted the government. The sentencing memorandum that accompanies it will often describe the nature and value of that assistance. In districts where the sealed supplement protocol is followed, the 5K1.1 motion is filed within the sealed record. In districts where it is not, the motion is, for practical purposes, an announcement.
Rule 35(b) permits a sentence reduction after sentencing for cooperation that occurs or produces results post-judgment. The same disclosure risks apply, and in some respects they increase: a Rule 35(b) motion filed months or years after sentencing, on a docket that has been dormant, draws attention. A filing appears where silence had settled.
Procedural Protections and Their Limits
The protections available to a cooperating defendant are procedural, not absolute. They operate at the level of document management and docket design, which means they can be undermined by anything that occurs outside the record.
A defendant who cooperates will sit for proffer sessions with agents and prosecutors, sometimes at the courthouse, sometimes at a government office, sometimes at a location selected for discretion. The physical act of meeting, the change in routine, the presence of defense counsel at times and in places where defense counsel would not otherwise be: these are observable. In multi-defendant cases, co-defendants’ attorneys monitor the progress of their own clients’ cases against the progress of others, and an unexplained delay in sentencing, a continuance requested by the government, a hearing noticed and then sealed: these can communicate cooperation to someone who understands the rhythm of federal practice.
Brady and Giglio obligations compound the difficulty. The government is required to disclose to the defense, in any case where a cooperator testifies, the terms of the cooperation agreement, any promises made, and any benefits received. This disclosure must occur before trial. The cooperator’s identity, at that point, enters the adversarial record, available to the defendant and, through the defendant, to anyone the defendant chooses to inform. The sealed supplement protects the cooperator’s identity before trial; it cannot protect it during one.
The U.S. Marshals Witness Security Program provides physical protection for qualifying witnesses. Admission is rare. The program addresses threats to life; it does not address threats to reputation, to a career, or to the web of relationships that constitute a life outside prison. And even within WITSEC, a cooperator who testifies does so in open court, with armed protection but without anonymity. The distinction between protection and concealment is one that clients discover at precisely the wrong moment.
There is a particular silence that fills a conference room when a client realizes, mid-preparation, that the sealed filing they believed would keep their name out of the record will not survive the trial itself. We have had that conversation enough times to recognize its weight before the question is asked. Every sealed document leads, if the case proceeds to trial, to an unsealed moment.
And some cooperators are identified through means no procedural mechanism can address. Jailhouse observation. Facility transfers. The fact that an inmate was escorted from the building on a day when no hearing was scheduled. In some federal facilities, inmates require others to post sentencing documents on their cell doors for inspection by the unit. The sealed record is, in those conditions, less a delay than a courtesy.
Timing and the Proffer
When to begin cooperating is a decision that shapes every subsequent protection available.
Cooperation that begins during the investigation, before charges are filed, offers the broadest range of options. The proffer itself can occur outside the court record entirely. No filing is created. No docket entry exists. If the cooperation produces results before the case is charged, there may be no public record of the defendant’s involvement at all.
Cooperation that begins after indictment but before plea introduces the sealed supplement. The timing of the plea, the timing of the sentencing, and the relationship between the two can be structured to reduce the footprint on the docket.
Cooperation that begins after sentencing depends on Rule 35(b) and inherits all of its visibility problems. The dormant docket comes to life. In districts without uniform sealing, the filing’s very existence is informative.
We approach the timing question differently than the standard advice would suggest. The conventional sequence is: charges are filed, plea negotiations begin, cooperation is discussed as a sentencing variable. We prefer, where the facts permit, to begin the conversation with the government before the docket exists (the proffer carries its own risks, including the possibility that statements made during the proffer, if cooperation fails, may be used for impeachment or to rebut a claim at trial, though the precise scope of that use remains a matter of some circuit-level disagreement). Not in every case, and not when the client’s exposure is uncertain enough that the proffer itself represents a concession. But the cleanest cooperation, from a confidentiality standpoint, is the kind that leaves no trace in the court file because it preceded the court file.
The sentence reduction available through cooperation can be substantial. In cases involving mandatory minimums, a 5K1.1 motion paired with a motion under 18 U.S.C. Section 3553(e) permits the court to sentence below the statutory floor. The difference between a sentence measured in decades and one measured in years can turn on a single filing. That filing, and the decision to pursue it, and the question of who will know about it and when, is the subject of the first conversation we have with any client considering this path.
A consultation assumes nothing and costs nothing. It is the point at which the record has not yet begun.
