The Basics of E-Discovery

2nd Edition


Welcome to the second edition of Exterro's Basics of E-Discovery guide. Like its predecessor, this guide will provide you with a wealth of useful information that you can use in your professional life whether you're an e-discovery novice or an experienced practitioner.

We've taken pains to keep what made the original Basics of E-Discovery a great resource. While informative, it's also entertaining. It uses straightforward language wherever possible. It simplifies where appropriate, and breaks up long blocks of text into bulleted lists where possible. It incorporates fun graphics and visual elements to make it a bit more inviting.

But a lot has happened since the original guide came out, not the least of which was the issuance of the 2015 amendments to the Federal Rules of Civil Procedure (FRCP), which include the ground rules governing e-discovery. We've updated the guide to address these changes in the law, as well as the continuing evolution in the technology of e-discovery.

In this second edition of the Basics of E-Discovery, you will get:

  • Updated best practices
  • Links to newer resources (as well as some classics!)
  • Simple explanations of key concepts and processes

We've even included links to some video elements to the guide that you can find on the website. We hope you'll enjoy it!

E-Discovery Overview

Learn about the e-discovery process and why it's important in this brief e-discovery overview video.

What Is Electronic Discovery (E-Discovery, e discovery, or eDiscovery)?

Electronic discovery (also known as e-discovery, e discovery, or eDiscovery) is a procedure by which parties involved in a legal case preserve, collect, review, and exchange information in electronic formats for the purpose of using it as evidence.

There are many different electronic formats - or electronically stored information (ESI), as it is known in the e-discovery world - that may be sought in e-discovery, ranging from common data sources, such as basic email and Microsoft documents, to more modern ones, like social media, instant messaging, and smartphone applications, to more arcane ones like files from a company-specific database.

It's worth noting that there is a big difference between criminal e-discovery and civil e-discovery. For the purposes of this guide we are going to focus on civil e-discovery.

How Does E-Discovery Work?

The Basics

We won't go into too much detail here, because we have an entire section devoted to the various e-discovery stages . One thing to know right off the bat is that e-discovery is not a single action – like taking a deposition or filing a motion. Rather e-discovery is a process comprised of many linked actions that begins when a lawsuit is reasonably foreseeable and lasts until documents are presented in court (in the event the case actually goes to trial).

Once litigation is reasonably foreseeable, potential litigants the legal duty to preserve potentially relevant ESI. Attorneys from both sides determine the scope of e-discovery, identify and preserve the relevant ESI, and make e-discovery requests and challenges of the opposing. Once parameters are set, ESI is then collected, analyzed, and formatted for use in court. While that description sounds simple, e-discovery is a dynamic, complex process that poses challenges to legal and IT teams alike. However, as e-discovery technology has matured, it is possible now to manage e-discovery from the requirement to preserve to document production in a single technology platform.

The E-Discovery process looks clear and linear on paper but in reality, the process can be much more complex.

Why should you care about E-Discovery?

While not typically the stuff of Hollywood courtroom dramas, e-discovery is a hugely important legal process. A ruling on a billion dollar class-action can hinge on the contents of just a few emails, often described as "smoking guns.".

Vast sums - and a ruling - can hinge on a single "smoking gun".
E-discovery is as fundamental to legal process as a scalpel is to a surgeon - but it isn't currently treated as such.

Why Is E-Discovery Such a Struggle?

So if we all agree that e-discovery is important, why do legal professionals struggle with it so much?

There is an old joke among lawyers that the reason they started studying law in the first place was simply to avoid math and science. That's probably not universally true, but it's undeniable that e-discovery burdens many legal professionals and tasks for which they aren't particularly knowledgeable or prepared.

Expert Perspective

E-Discovery Struggling to Becoming Intuitive and Seamless

Electronic discovery is coalescing around the theme of “user experience." The transition from DOS to Windows opened computing to everyone. Similarly, e-discovery is struggling to design the transformative killer app(s) or platform that will render e-discovery as intuitive and seamless as operating an iPhone and allow genuine e-discovery to inform all litigation matters, disputes, and investigations.
