Abstract

The complexity of statutory legislation can generate confusion and disagreement in interpretation even among experts and can leave ordinary citizens disempowered. Technological 'solutions', even with stakeholders' best interests in mind, can exacerbate this sense of estrangement from the law. We are exploring an alternative application of technology in this area: a digital 'sandbox' environment for legislators, lawyers, judges, and citizens to define and explore the consequences of legislation. Our approach employs a 'lightweight' method to computational modeling, using automated analysis to uncover hidden assumptions and unintended consequences. As a case study, we are focusing on a number of U.S. statutes that define conditions under which prior convictions can be expunged from an individual's public record. We use the Alloy modeling language and analyzer to explore consequences of expungement statutes. Starting with the State of Michigan's Clean Slate Law and then extending to similar statutes in Utah and Arizona, we can model varying interpretations of the law in terms of modular changes to a base model, and then use the Alloy analyzer to explore the consequences of these interpretations. We have developed a user interface for the model that is tuned to the needs of individuals seeking expungement and their legal assistants, determining which convictions within the individual's record can be expunged under varying interpretations, and explaining why some convictions may not be expunged. This application not only serves as a proof of concept for our larger sandbox vision but also has promise as a useful tool for individuals navigating the complexities of expungement.
