The Client

An Am Law 10 firm representing a global entertainment company that received a second request from the US Department of Justice (DOJ) in regards to an acquisition valued at $60 billion.

The Challenge

  • Over 30 TBs of data collected in response to the second request
  • 60 days to complete the collection, processing, review, and production of responsive data
  • Unusually high volume of duplicative data due to uncommonly frequent backups by the client's cloud-based backup system

The TLS Solution

Faced with these difficult circumstances, TLS, outside counsel, and the corporate client rapidly deployed a highly customized workflow consisting of three major elements: (1) forensic deduplication prior to ingestion into the e-discovery processing tool, (2) application of Pre-Review Analytics® in close consultation with the DOJ, and (3) negotiation and implementation of technology-assisted review protocols.

In the end, the DOJ agreed that its demands had been met and the client was able to meet their 60-day deadline.

"It is now black letter law that where the producing party
wants to utilize TAR for document review, courts will permit it."
