Charging and plea decisions belong to the executive, so the writ in this area runs against judges who take those decisions over rather than against prosecutors.
Two rules divide authority over how a federal criminal case ends. Fed. R. Crim. P. 11 tells the court what it may and may not do about a plea agreement. Fed. R. Crim. P. 48(a) tells the government it needs leave of court to dismiss a charge. Both leave room for disagreement about where judicial supervision stops.
Mandamus is the vehicle in which that disagreement usually surfaces, because a district court order refusing to accept an agreement or declining to dismiss a charge is not a final judgment and no statute makes it appealable.
What Rule 11 assigns to whom
The rule allocates roles precisely, and the allocation is what petitions are built on.
| Provision | What it does | Effect |
|---|---|---|
| Rule 11(b) | Requires the court to address the defendant personally, ensure the plea is voluntary, and determine a factual basis | A judicial duty the court must perform |
| Rule 11(c)(1) | States that an attorney for the government and the defendant's attorney may discuss and reach a plea agreement, and that the court must not participate in those discussions | The clearest prohibition in the rule |
| Rule 11(c)(1)(A) | The government agrees not to bring or to move to dismiss other charges | Binding on the court only if the agreement is accepted |
| Rule 11(c)(1)(B) | The government recommends a sentence or agrees not to oppose one | Not binding; the defendant has no right to withdraw if the court declines the recommendation |
| Rule 11(c)(1)(C) | The parties agree that a specific sentence or range is the appropriate disposition | Binding once accepted; the court may accept, reject, or defer under Rule 11(c)(3) |
| Rule 11(c)(5) | Governs rejection of a (A) or (C) agreement | The court must advise the defendant and give an opportunity to withdraw the plea |
Rule 48(a) and what leave of court protects
The text is short: the government may, with leave of court, dismiss an indictment, information, or complaint, and may not dismiss the prosecution during trial without the defendant's consent. Rule 48(b) separately allows the court to dismiss where unnecessary delay occurs in presenting a charge to a grand jury, filing an information, or bringing a defendant to trial.
Rinaldi v. United States, 434 U.S. 22 (1977), identifies the principal object of the leave requirement: protecting a defendant against prosecutorial harassment, such as charging, dismissing, and recharging when the government moves to dismiss over the defendant's objection. On that reading, an unopposed dismissal motion presents the narrowest occasion for judicial scrutiny, because the interest the requirement exists to protect is not engaged.
The discretion the writ cannot reach
Nothing in mandamus doctrine gives a court power over the decision to charge. United States v. Armstrong, 517 U.S. 456 (1996), applies a presumption of regularity to prosecutorial decisions and requires a demanding showing before discovery into a selective prosecution claim is permitted. Bordenkircher v. Hayes, 434 U.S. 357 (1978), treats the decision whether and what to charge as generally resting in the prosecutor's discretion. Heckler v. Chaney, 470 U.S. 821 (1985), states the administrative counterpart: an agency's decision not to enforce is presumptively unreviewable.
The consequence for petitioners is direct. A victim, a competitor, or a member of the public who wants a prosecution brought is asking a court to order a discretionary act, and mandamus requires a ministerial one. That is the settled answer, not a close question.
Where the writ has actually issued
United States v. Fokker Services B.V., 818 F.3d 733 (D.C. Cir. 2016), is the clearest modern example. The district court refused to exclude time under the Speedy Trial Act's deferred prosecution agreement provision because it considered the charging decisions and the conditions of the agreement inadequate. The D.C. Circuit granted mandamus, reading the statute's approval requirement narrowly: it exists to ensure the agreement is genuinely aimed at allowing the defendant to demonstrate compliance with the law rather than serving as a pretext to evade the Act's time limits, not to license judicial review of charging choices.
In re Flynn, 973 F.3d 74 (D.C. Cir. 2020) (en banc), shows the other side. The en banc court denied a mandamus petition seeking to compel immediate dismissal under Rule 48(a), holding that relief was premature because the district court had not yet ruled and ordinary review remained available. It expressly declined to decide the full scope of a district judge's authority under the rule.
The fact patterns that produce petitions
Read together, the cases suggest the line runs between supervision of process and substitution of judgment.
- Participation in negotiations. Rule 11(c)(1) is categorical, and a judge who suggests terms has done something the rule forbids rather than something it commits to discretion.
- Conditioning acceptance on charging choices. A court that will accept a plea only if different charges are brought is directing an executive decision.
- Refusing a Rule 48(a) motion on policy grounds. Where the defendant consents, the harassment concern Rinaldi identified is absent, and the basis for withholding leave narrows accordingly.
- Appointing amici and setting an inquiry. In re Flynn treated these as insufficiently intrusive to warrant the writ at that stage, which locates them inside the district court's case-management authority for the time being.
Victims as a separate channel
The Crime Victims' Rights Act creates rights that attach at exactly this stage: the right to confer with the attorney for the Government under 18 U.S.C. § 3771(a)(5), the right to be reasonably heard at a proceeding involving a plea under § 3771(a)(4), and, since 2015, the right to timely notice of a plea bargain or deferred prosecution agreement under § 3771(a)(9). In re Dean, 527 F.3d 391 (5th Cir. 2008), addressed a plea negotiated without notifying victims and concluded the right to confer should have been afforded.
The remedy is still limited. Section 3771(d)(5) allows a motion to re-open a plea only where the victim asserted the right to be heard and was denied, petitioned within 14 days, and the accused has not pled to the highest offense charged. A victim can enforce process and cannot rewrite the bargain.
What the remedy does not include
Four limits recur. The writ cannot compel the government to file a charge, offer an agreement, or move to dismiss one. It cannot compel a court to accept an agreement the rule permits it to reject, because Rule 11(c)(3) commits acceptance to the court's judgment. It cannot resolve the merits of a sentencing dispute embedded in a Rule 11(c)(1)(C) agreement. And relief remains discretionary under the third condition of Cheney v. United States District Court, 542 U.S. 367 (2004), so a petitioner who identifies a genuine overreach may still be told to wait for the district court to act.
The boundary is contested at its edges. How far a district judge may probe the reasons behind an unopposed Rule 48(a) motion is a question In re Flynn deliberately left open, and no Supreme Court decision fixes it.
Key points
- Fed. R. Crim. P. 11(c)(1) categorically bars the court from participating in plea discussions, which makes a violation easier to frame as usurpation than as error.
- Rinaldi v. United States identifies protection of the defendant against prosecutorial harassment as the principal object of Rule 48(a)'s leave requirement.
- United States v. Fokker Services B.V. granted mandamus where a district court used the Speedy Trial Act's deferred prosecution provision to review charging decisions.
- In re Flynn denied mandamus as premature and expressly left open how far a district judge may probe an unopposed Rule 48(a) motion.
- A victim can enforce the CVRA rights to notice, conferral, and a hearing, but § 3771(d)(5) sharply limits reopening a plea once it is entered.
