JM 9-27.530
If a plea of nolo contendere is offered over the government's objection, the attorney for the government should state for the record why acceptance of the plea would not be in the public interest; and he/she should also oppose the dismissal of any charges to which the defendant does not plead nolo contendere.
Comment. When a plea of nolo contendere is offered over the government's objection, the prosecutor should take full advantage of Rule 11(a)(3) of the Federal Rules of Criminal Procedure, to state for the record why acceptance of the plea would not be in the public interest. In addition to reciting facts that could be proved to show the defendant's guilt, the prosecutor should bring to the court's attention whatever arguments exist for rejecting the plea. At the very least, a forceful presentation should make it clear to the public that the government is unwilling to condone the entry of a special plea that may help the defendant avoid legitimate consequences of his/her guilt. If the nolo plea is offered to fewer than all charges, the prosecutor should also oppose the dismissal of the remaining charges.
