Last spring, Judge James Chamblin, of the 20th Judicial Circuit Court of Virginia, approved defendants' e-discovery request to process electronically stored information using "predictive coding" methods, despite protests from plaintiffs in Global Aerospace Inc. et al., v. Landow Aviation, L.P. dba Dulles Jet Center, et al.

Chamblin's order related to e-discovery about a collapsed airplane hangar in the closely-watched litigation.

Defense counsel at Schnader Harrison Segal & Lewis, and also at Baxter, Baker, Sidle, Conn & Jones, used OrcaTec's Document Decisioning Suite technology. This week, Atlanta-based OrcaTec will announce that the process is finished after plaintiff's counsel at Jones Day did not object to the results by a recent deadline, said multiple people close to the case.

Wednesday, no one affiliated with the case would comment, including OrcaTec officials, plaintiff counsel at Jones Day, and the consultants who administered the software at JurInnov and ReviewLess. An email query to defnse counsel was not answered.

Predictive coding is currently being used in other high-profile cases, most notably in the labor law case of Monique da Silva Moore, et al. v. Publicis Group SA. However, Global Aerospace is believed to be the first time a judge ordered the software's use over plaintiff objections.

Predictive coding, aka technology-assisted review, uses computer algorithms and human input to determine relevant electronically stored information. It is controversial because of industry debates about its effectiveness as compared to traditional all-human review, and about how to train the software and verify results.

Technology consultant David Lewis, who co-founded the U.S. government's TREC Legal Track and worked on other predictive coding cases, said the current Global Aerospace development is important but that it leaves room for other courts to add their own landmarks.

"This is an interesting and encouraging legal milestone in the acceptance of an already widely used technology," Lewis said, from Chicago. There's still the question of whether courts will ever require minimum statistically verified levels of effectiveness from predictive coding software, he observed. "That would be a very big change in the law, but it seems like something that's going to be fought over at some point," Lewis said. "It is an interesting open legal question whether courts are going to ask for that."

E-discovery analyst David Horrigan, of 451 Research, expressed his surprise that Global Aerospace didn't head in a different direction and wondered aloud why plaintiff's counsel did not object to the results after initially objecting to the technology itself.

"It's disappointing this issue has apparently been resolved on [plaintiff's] missed procedural deadline," he said. "Not unlike the predictive coding vs. keyword search debate in Kleen Products being postponed, if this court deadline has really been missed, or if the plaintiffs chose to give up their challenge, we've lost an opportunity for a court ruling on predictive coding being decided on the merits."

    The judge in the case had required that in order for the predictive coding culling to pass muster,Schnader needed to show that at least 75% of the responsive documents in the 1.3 million document set in question had been found. Human review generally finds 50% or less.

    OrcaTec's OrcaPredict found 81% of the responsive documents in just a few days, and reduced the document set 83%. After a five-attorney team's review, about 173,000 documents were produced for the other side.

    Chair of Schnader's e-Discovery Practice Group and lead attorney for the eDiscovery issues on the case, Thomas C. Gricks III, responded to the Global Aerospace result as follows: “Using a strict manual review process, just culling the irrelevant documents would likely have taken as much as 20,000 man-hours to review, at an anticipated cost of $1.5 million. We were able to generate results that measurably exceed typical manual review, at a fraction of the cost, and we were prepared to produce the vast majority of the responsive documents within a tight timeframe.”

    OrcaTec's CTO and Chief Scientist Herbert L. Roitblat, Ph.D., commented: “OrcaTec’s predictive coding has been attaining the Global Aerospace level of Precision and Recall – and even much better – on a very regular basis. “You can see on the OrcaTec dashboard the percentage of Recall you’re achieving as you code. The clients here were aiming for greater than 75%, which is vastly better than human review, and they got 80%. We can’t help but be proud of that.”

    Karl Schieneman, the predictive coding expert whose company, Review Less, brought OrcaTec into the litigation, said, “With the ever-increasing amount of data that corporations are storing, pre-trial e-Discovery costs are becoming absolutely prohibitive without the use of technologies like OrcaTec’s predictive coding.”

    At LegalTech New York on January 30, Roitblat, Gricks and Schieneman will join US Magistrate Judge James C. Francis IV (S.D.N.Y.), Milberg partner Ariana Tadler and Conor Crowley of Virginia's Crowley Law Office for a mock hearing on predictive coding.
