Is Challenging Someone to a Duel Legal in Colorado After the 2026 Regulatory Updates?

No, challenging someone to a duel remains illegal in Colorado under state statutes prohibiting mutual combat and public disorder. While historical dueling laws were repealed in 1971, Colorado’s criminal code (C.R.S. § 18-1-703) still criminalizes consensual violence, and local ordinances in Denver and Colorado Springs explicitly ban “dueling” as a form of assault. The Colorado Attorney General’s 2024 guidance reinforces that even “consensual” fights face prosecution under assault or disturbing the peace statutes.

Key Regulations for Challenging Someone to a Duel in Colorado

  • Assault Prohibitions (C.R.S. § 18-3-204): Engaging in or soliciting a duel constitutes third-degree assault, punishable by up to 12 months in jail and $750 in fines, regardless of mutual consent.
  • Public Disorder Ordinances: Municipal codes in Denver (Sec. 38-28) and Colorado Springs (Sec. 9.4.103) classify dueling as a breach of peace, authorizing immediate police intervention and municipal citations.
  • Firearms Restrictions (C.R.S. § 18-12-108): If the duel involves weapons, offenders face enhanced penalties under Colorado’s illegal discharge laws, with mandatory sentencing enhancements for use of firearms in prohibited activities.
