What it is

A consensus commentary on when mobile device data is within the scope of civil discovery and how to collect and produce it proportionately, covering possession, custody or control over personal devices, targeted versus full extraction, and the form of production for message threads.

Who it is for, and when

This is the most current legal guidance on the collection examiners are asked to perform most often, so read it before scoping a phone collection or arguing about one. Lawyers should read the control and proportionality sections before demanding or resisting device imaging. It is also useful for setting client expectations about what a phone collection actually produces.

What it does not cover

It is not binding and its legal analysis is US civil discovery only, with no coverage of criminal seizure or consent. It is not a technical guide: it does not evaluate extraction tools, address locked or encrypted devices as an engineering problem, or tell you how to validate an extraction. The PDF requires a free Sedona Conference account.

Standards are revised. Confirm the current revision with the publisher before citing this.
  • Fourteen consensus principles on producing electronically stored information in civil litigation, with commentary, revised to reflect the 2015 amendments to the Federal Rules of Civil Procedure. Courts cite it more often than any other non-binding ediscovery text.

  • The federal sanctions rule for lost ESI. It applies only where information that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it and it cannot be restored or replaced through additional discovery, and it reserves the severe measures — adverse inference, dismissal, default — for a finding that the party acted with intent to deprive another party of the information's use.

  • A consensus commentary on auto-deleting and disappearing-message applications: whether adopting them is defensible, what happens to the preservation duty when a trigger occurs, and how Rule 37(e) applies when messages are gone by design.

  • A roughly 1,500-page updated treatise covering discovery and admission of electronic evidence against federal and state rules and case law, in eight chapters, with companion Best Practices Guides including an information technology primer for lawyers.

  • A commercial investigation and data-processing platform aimed at very large unstructured data sets, combining forensic-style processing with ediscovery-grade indexing, deduplication, and export. Nuix now positions its offerings under the Nuix Neo platform, with Workstation still listed as a product alongside Nuix Discover for review.
