A Predictive Role for Intermediate Legal Concepts

Experiments described here demonstrate a role that intermediate legal con- cepts play in predicting the decisions of new cases. The experiments compare vari- ations of each of an Issue-Based Prediction algorithm (IBP) and a CATO prediction algorithm in which the use of legal concepts are ablated in various ways. The results confirm those legal philosophical theories that assert that intermediate concepts in le- gal principles perform a guiding or extending role in deciding new cases.
