This pocket guide was developed to help judges manage complex e-discovery in federal criminal cases. The advantages of electronically stored information (ESI, or e-discovery) include speed, efficiency, and quality of information. To ensure these benefits are realized, judges and lawyers working on federal criminal cases need guidance on how best to address e-discovery issues. This guide helps judges to ensure that e-discovery moves smoothly, trial deadlines are met, and the parties and courts are able to review and identify critical evidence.
