The Wyoming High School Mock Trial program has been organizing the annual mock trial competition for high school teams in Wyoming for more than 20 years. We help teens to gain understanding of the legal system and provide opportunities for teams to participate in competitive “trials,” as they demonstrate abilities they’ve learned to question, think critically, argue and work as teams.

WHSMT is supported by generous grants from the Wyoming State Bar, and we are grateful for the attorneys and judges who volunteer to coach, score and preside for our program.

Teams are composed of 6-8 students from any high school, and WHSMT permits teams to include eighth graders in the state competition. WHSMT releases a “case” in September, alternating criminal and civil. Students have about 10 weeks to prepare to present both sides – defense and prosecution/plaintiff – at our state competition, usually around Thanksgiving and usually in Cheyenne.

Our 2022 case is State of Wyoming vs. Parker Madison, accused of murdering a long-time friend and partner in a casino business in Carter City, Wyoming. The prosecution thinks it has a strong case for means, motive and opportunity, but that is for the teams of Wyoming high school students to argue about in the state competition Dec. 3, 2022, in Cheyenne.

Details will follow about logistics for the tournament “trials.”
