Technological advancements are improving how courts operate by changing the way they handle proceedings and interact with litigants. Court Innovations is a socially minded software startup that enables citizens, law enforcement, and courts to resolve legal matters through Matterhorn, an online communication and dispute resolution platform. Matterhorn was conceived at the University of Michigan Law School and successfully piloted in two Michigan district courts beginning in 2014. The platform now operates in over 40 courts and in at least eight states, and it has facilitated the resolution of more than 40,000 cases to date.2 These numbers will continue to grow as new categories of disputes and other legal matters become eligible for online management and resolution and as more court systems recognize the economic and social benefits of adopting online platform technology.3 This case study chronicles the development, implementation, and refinement of Matterhorn.
