Rule 410: Pleas, Plea Discussions, and Related Statements
What is Pleas, Plea Discussions, and Related Statements?
Rule 410 protects defendants who engage in plea bargaining. If a defendant enters into plea negotiations with prosecutors but no deal is reached, or if a deal is reached but the guilty plea is later withdrawn, the statements the defendant made during that process cannot be used against them in any subsequent proceeding, whether civil or criminal.

Rule Text
In a civil or criminal case, evidence of the following is not admissible against the defendant who made the plea or participated in the plea discussions: a guilty plea that was later withdrawn; a nolo contendere (no contest) plea; any statement made during a proceeding on either of those pleas under Federal Rule of Criminal Procedure 11; or any statement made during plea discussions with an attorney for the prosecuting authority if the discussions did not result in a guilty plea or they resulted in a later-withdrawn guilty plea.
Plain English Explanation
Rule 410 protects defendants who engage in plea bargaining. If a defendant enters into plea negotiations with prosecutors but no deal is reached, or if a deal is reached but the guilty plea is later withdrawn, the statements the defendant made during that process cannot be used against them in any subsequent proceeding, whether civil or criminal.
The rationale mirrors that of Rule 408 for civil settlements: the criminal justice system depends on plea bargaining to function. Over 90% of federal criminal cases are resolved by guilty pleas, many through plea negotiations. If defendants feared that their statements during failed plea talks could be used against them at trial, they would be far less willing to negotiate, grinding the system to a halt.
The rule specifically protects four categories: withdrawn guilty pleas, nolo contendere pleas, statements made during Rule 11 proceedings (the formal plea hearing), and statements made during plea discussions with prosecutors. However, the Supreme Court has held that defendants can waive Rule 410 protections as part of a plea agreement, which is now common practice.
Key Points
- 1Withdrawn guilty pleas and nolo contendere pleas are inadmissible against the defendant
- 2Statements made during plea discussions with prosecutors are protected if no guilty plea results
- 3The rule only protects statements made to prosecutors — not to law enforcement officers unless acting as agents in plea discussions
- 4Defendants can waive Rule 410 protections (United States v. Mezzanatto)
- 5Protections apply in both civil and criminal proceedings
Common Exam Issues
- Distinguishing plea discussions (protected) from ordinary conversations with law enforcement (not protected under 410)
- Whether the defendant reasonably believed they were engaged in plea negotiations with the prosecutor
- The waivability of Rule 410 protections and the significance of Mezzanatto
- Nolo contendere pleas — they cannot be used in subsequent civil cases as admissions
Landmark Cases
- United States v. Mezzanatto
