Is Challenging Someone to a Duel Legal in Missouri After the 2026 Policy Reforms?

No, challenging someone to a duel in Missouri violates state statutes prohibiting disorderly conduct and endangering public safety, even if no physical altercation occurs. Missouri Revised Statutes § 569.070 criminalizes engaging in conduct that recklessly creates a substantial risk of public inconvenience, alarm, or harm, which includes dueling. Local prosecutors in St. Louis and Kansas City have pursued charges under this statute for similar provocations, and 2026 legislative updates expanded penalties for organized or facilitated duels.
