O’Melveny Worldwide

Adrian Pollner is a highly skilled lawyer who advises clients on the management, organization, and production of data and information in corporate investigations and white collar criminal defense matters. Leveraging his experience as a litigator and deep experience with data analytics and eDiscovery technology, Adrian helps clients develop document retention and production plans for Department of Justice (DOJ) investigations and litigation and negotiates the use of those plans with government agencies. Adrian is adept at educating both clients and regulators on the constantly changing landscape of eDiscovery processes and technology, which allows for efficient and cost-effective document productions without expensive and time-consuming discovery disputes.

Adrian’s experience includes managing the eDiscovery process for the DOJ’s approval of a health insurer’s acquisition of a competitor. In that representation, Adrian analyzed the scope of the potentially relevant multi‐million documents, implemented a national legal hold, and developed a production strategy that did not produce everything requested by the DOJ, yet that received its approval. He also has considerable experience replacing eDiscovery counsel in ongoing litigation. In the last year, Adrian managed the eDiscovery efforts of an O’Melveny team that took over the representation of a financial services company that had already been subject to multiple adverse discovery rulings. He designed and implemented an overhaul of the privilege review and privilege log process, including team reorganization and retraining. The process Adrian designed resulted in the timely completion of the client’s productions without any challenges to the privilege log.
