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 2021 case is Crook Industries vs. Cody Weston, a case that gets into the world of Instagram influencers. It is provided on the “2021 WHSMT Case” page, along with National High School Mock Trial rules of competition (newly amended to accommodate virtual participation) and the rules of evidence used by mock trial. Watch the competition page for corrections and comments on the case.

With the unpredictability of team travel and in-person competition, Once again we are planning the state competition to be virtual, tentatively scheduled for Dec. 3 and Dec. 4, Dec. 4, 2021. We will post updates on our Facebook page and on this Website. Contact WSMT Coordinators Marguerite Herman and George Powers at Or call/text Marguerite Herman at 307-630-8095.
