Washington Best Practices for Electronic Discovery in Criminal Cases is a set of standards developed by the Washington Supreme Court to ensure uniformity, accuracy, and efficiency in the discovery of electronically stored information (ESI) relevant to criminal cases. The Best Practices provide guidance to criminal justice professionals in the collection, preservation, and production of ESI. The Washington Best Practices for Electronic Discovery in Criminal Cases includes two types of Best Practices: General Best Practices and Technology-Specific Best Practices. General Best Practices include guidance on the roles and responsibilities of prosecutors, defense attorneys, and court personnel in the discovery process, including protocols for creating and maintaining an effective chain of custody. Technology-Specific Best Practices provide guidance on the collection, preservation, and production of ESI for specific electronic media, including email, text messages, audio/video recordings, and social media accounts. The Washington Best Practices for Electronic Discovery in Criminal Cases are intended to encourage best practices in the management of ESI and ensure that the criminal justice professionals are able to effectively use ESI as evidence in criminal proceedings.
