Washington: Scientists have developed a new artificial intelligence system that can predict court decisions better than legal scholars, even with less information. Researchers, including those from The Stanford Centre for Legal Informatics, used the US Supreme Court Database - which contains information on cases dating back to 1791 Using this, they built an algorithm for predicting any justice's vote at any time. Researchers drew on 16 features of each vote, including the justice, the term, the issue, and the court of origin.

They also added other factors, such as whether oral arguments were heard. For each year from 1816 to 2015, the team created a machine-learning statistical model. It looked at all prior years and found associations between case features and decision outcomes. Decision outcomes included whether the court reversed a lower court's decision and how each justice voted. The model then looked at the features of each case for that year and predicted decision outcomes.
