New systems of e-discovery are emerging that are designed for today’s digital world. Unlike most existing e-discovery systems, they are not mere adaptations of old paper discovery ways. The new methods use an entirely new collaborative approach and technologies, exemplified by predictive coding software. Although this paradigm shift in discovery is just starting, many of the contours of the new methods are already apparent.
In general terms, we are coming to realize that our current linear, confrontative, one-dimensional, largely manual, Bates stamp approach to discovery must be replaced with a multidimensional, cooperative, iterative, largely automated, hash value approach.
A consensus is forming in the legal community that human review of documents in discovery is expensive, time consuming, and error-prone. There is growing consensus that the application of linguistic and mathematic-based content analysis, search and retrieval technologies, and tools, techniques and process in support of the review function can effectively reduce the cost, time, and error rates.

Attorneys are beginning to embrace new technologies as indispensable tools around which new legal processes and procedures are built. They understand that expensive human review must be significantly curtailed and re-directed to the use of new software tools, not just keyword searching. The new tools include context and conceptual search software, advanced multidimensional indexing, and other new types of artificial intelligence based predictive coding search and review programs. See Eg.: Kevin D. Ashley, Will Bridewell, Emerging AI+Law Approaches to Automating Analysis and Retrieval of ESI in Discovery Proceedings, ICAIL 2009 Global E-Discovery/E-Disclosure Workshop.
The legal profession is at a crossroads: the choice is between continuing to conduct discovery as it has “always been practiced” in a paper world — before the advent of computers, the Internet, and the exponential growth of electronically stored information (ESI) — or, alternatively, embracing new ways of thinking in today’s digital world. Cost-conscious clients and over-burdened judges are demanding that parties now undertake new approaches to solving litigation problems.
Baron and Burke, The Sedona Conference® Commentary on Achieving Quality in the E-Discovery Process; (May 2009) in the Executive Summary.
Many of our leading jurists, information scientists, academics, scholars, writers, and legal practitioners recognize that the old methods and attitudes that worked for paper no longer work for ESI. Victor Stanley, Inc. v. Creative Pipe, Inc., 250 F.R.D. 251 (D. Md. 2008) (Judge Grimm); Securities and Exchange Commission v. Collins & Aikman Corp., 2009 WL 94311 (S.D.N.Y., 2009) (Judge Scheindlin); Disability Rights Council of Greater Wash. v. Wash. Metro. Area Transit Auth., 2007 WL 1585452 (D.D.C. 2007) (Judge Facciola); United States v. O’Keefe, 2008 WL 449729 (D.D.C. 2008) (Judge Facciola); William A. Gross Const. Associates, Inc. v. American Mfrs. Mut. Ins. Co., _F.R.D._, 2009 WL 724954 (S.D.N.Y. 2009) (Judge Peck); Digicel (St. Lucia) Ltd & Ors v. Cable & Wireless & Ors,  EWHC 2522 (Ch) (Justice Morgan) (UK decision). Moreover, scientific research has shown that keyword search alone is ineffective and multi-modal approaches that use keyword and other methods work far better. See: Child’s Game of “Go Fish” is a Poor Model for e-Discovery Search; The Multi-Modal “Where’s Waldo?” Approach to Search and My Mock Debate with Jason Baron; Secrets of Search: Parts One, Two, and Three.
… a party that uses advanced analytical software applications and linguistic tools in screening for privilege and work product may be found to have taken ‘reasonable steps’ to prevent inadvertent disclosure.
Software has advanced to the point that computer review alone is at least as accurate as manual review, the so-called gold standard, and is getting better all of the time. Maura R. Grossman & Gordon v. Cormack, Technology-Assisted Review in E-Discovery Can Be More Effective and More Efficient Than Exhaustive Manual Review, Rich. J.L. & Tech., Spring 2011, at 48; Herbert L. Roitblat, Anne Kershaw, Patrick Oot, Document Categorization in Legal Electronic Discovery: Computer Classification vs. Manual Review (Electronic Discovery Institute 2009); Also see my prior blogs: Secrets of Search: Parts One, Two, and Three; and, The Legal Implications of What Science Says About Recall.
Furthermore, highly focused, multiple-phase production is becoming an accepted best practice norm, replacing the old paper ways of trying to discover all possible relevant writings in a single, broad, boilerplate production request and production. Covad Communications Co. v. Revonet Inc., 2008 WL 5377698 (D.D.C. 2008) (boilerplate paper forms still used to request ESI); Shannon Capone Kirk, Kristin Ali, The Need for Art and Surgery in Discovery, Chapter 16 of Losey, Electronic Discovery (West 2010).
You can't afford the truth!
When balancing the cost, burden, and need for electronically stored information, courts and parties should apply the proportionality standard embodied in Fed. R. Civ. P. 26(b)(2)(C) and its state equivalents, which require consideration of the technological feasibility and realistic costs of preserving, retrieving, reviewing, and producing electronically stored information, as well as the nature of the litigation and the amount in controversy.
Also see Final Report on the Joint Project of the American College of Trial Lawyers and the Institute for the Advancement of the American Legal System (2009) (At page 7: “Proportionality should be the most important principle applied to all discovery.”) Also see my recent blog: Bottom Line Driven Proportional Review.
The new discovery methods rely heavily upon various types of sampling and other metric based quality control systems. Rule 34(a)(1), Federal Rules of Civil Procedure specifically allows sampling as a form of discovery and the official Rules Commentary confirms that this provision is intended to cover ESI as well as tangible objects. Also see In re Vioxx Products Liability Litigation, No. 06-30378, 06-30379 2006 W.L. 1726675, at *2 n.5 (5th Cir. May 26, 2006) (“By random sampling, we mean adhering to a statistically sound protocol for sampling documents.”); In Re Seroquel Products Liability Litigation, 244 F.R.D. 650 (M.D. Fla. 2007) (“Common sense dictates that sampling and other quality assurance techniques must be employed to meet requirements of completeness.”); Mt. Hawley Ins. Co. v. Felman Production, Inc., 2010 WL 1990555 (S.D. W. Va. May 18, 2010) (plaintiff’s attorney client privilege was lost because the plaintiff “failed to perform critical quality control sampling to determine whether their production was appropriate and neither over-inclusive nor under-inclusive.”); McPeek v. Ashcroft, 202 F.R.D. 31, 34 (D.D.C. 2001) (ordering initial limited search of backup tapes within dates determined to be most relevant, as a “rational starting point” for ESI search). Also consider the opinion of Kipperman v. Onex Corp., 260 F.R.D. 682 (N.D. Ga. 2009). The court required production of “sample” backup tapes to weigh the volume and importance of the information on the tapes against the costs of their restoration and production before deciding whether to permit additional discovery. After reviewing the results of the sample, the court held that the ESI contained on the tapes was highly relevant and so compelled further discovery saying: “I don’t . . . declare these to be smoking guns but they certainly are hot and they certainly do smell like they have been discharged lately.” Id. at 691.
We know that the new methods should be based upon open communications and sharing of information of preliminary findings with the requesting party. This is what George Paul and Jason Baron call “virtuous cycle iterative feedback loops.” Information Inflation: Can the Legal System Adapt? Supra at pgs. 32-36.
The parties need to exchange expert views and gain a common understanding of the relevance parameters. Scientific investigations on the effectiveness of search and review processes performed by the TREC Legal Track confirm this. Douglas W. Oard, Bruce Hedin, Stephen Tomlinson and Jason R. Baron, Overview of the TREC 2008 Legal Track. Studies also confirm that at least one meeting between opposing counsel to share initial review results, and consider alterations based on mutual disclosure and input, significantly increases the overall precision and recall of the project. Jason R. Baron, Douglas W. Oard, Feng C. Zhao, Improving Search Effectiveness in the Legal E-Discovery Process Using Relevance Feedback.
For this new system of open, iterative communication processes to work, lawyers must change their attitudes. The total adversarial approach to discovery, which is now prevalent in the United States, must be replaced by strategic cooperation with active judicial management where required. This is critical for the new iterative open process to work at maximum efficiency.
Cooperative discovery processes have long been required by the rules of professional ethics and procedure, but they were frequently misunderstood or ignored by attorneys succumbing to economic pressures to win at all costs. Losey, Lawyers Behaving Badly, 60 Mercer L. Rev. 983 (Spring 2009). They were also not well understood or enforced by the courts. Mancia v. Mayflower Textile Services. Co., 253 F.R.D. 354 (D.Md. Oct. 15, 2008). But this has changed with recent scholarship and experiences showing the importance of cooperation in e-discovery. The Case for Cooperation, 10 Sedona Conf. J. 339 (2009 Supp.) (Preface by Justice Breyer; lead article by Sedona Conference Working Group, edited by Bill Butterfield, Richard Braman, Ken Withers and others); The Bull’s-Eye View of Cooperation in Discovery, 10 Sedona Conf. J. 363 (2009 Supp.) (Professor Steven S. Gensler); Mancia v. Mayflower Begins a Pilgrimage to the New World of Cooperation, 10 Sedona Conf. J. 377 (2009 Supp.) (Ralph Losey).

Discovery of evidence and the legal analysis of relevancy and privilege determinations are at the heart of our legal system. They are essential to the common law evidence based system of justice. The methods and tools used in paper discovery did not work with the vast stores of digital information ubiquitous in the Twenty-First Century. That is why e-discovery became so expensive and riddled with mistakes. That is why completely new methods and tools emerged for digital discovery, which, in 2012, finally caught on. The last impediment of no judicial approval has been destroyed. The way is now clear.
The old linear methods of reading all papers are being replaced by iterative methods that include predictive coding. The new ways involve cooperative, multidimensional, cyclic approaches that focus on proportional, phased productions.
The stated goal of the new legal processes has also changed. The goal is now legally adequate recall, not complete recall. It is discovery of all highly relevant information, but not necessarily all relevant information. Adequacy is determined on a case-by-case basis as necessary to render justice and, at the same time, not unfairly burden the parties to litigation. It is based on reasonability and proportionality, not a delusional notion of perfection that, in fact, has never been required by the Law.
The leaders in e-discovery have already made this change and are embracing and refining these new methods. They are managers of complex technologies and iterative quality control processes. They lead an e-discovery team. This trend will continue because it works. It saves money and mitigates risks.
The old-school, linear, confrontative, one-dimensional, largely manual, Bates stamp approach to e-discovery has already been abandoned by all of the top experts in the field. The old ways have been replaced by a new nine-step process I described in Bottom Line Driven Proportional Review, or something close to that. The new methods are multidimensional, cooperative, iterative, and include predictive coding as part of a multimodal approach. The predictive coding software works, and, if it is properly used with the new legal methods, will be accepted by courts. See eg. Chris Dale’s Judge Peck’s Predictive Coding Opinion – reporting the reaction and the case and articles cited therein. The time to employ these new methods is now. You have nothing to lose but high expense and low recall.
