Jenner & Block Partner David M. Greenwald served as a team leader for The Sedona Conference’s Commentary on Protection of Privileged ESI. The book is a project of The Sedona Conference Working Group 1 -- Electronic Document Retention and Production. The Sedona Conference is a research and educational institute dedicated to the advanced study of law and policy in the areas of complex litigation, antitrust law, and intellectual property rights. The mission of TSC is to drive the reasoned and just advancement of law and policy by stimulating ongoing dialogue among leaders of the bench and bar to achieve consensus on tipping point issues. The Commentary, among other topics, discusses Federal Rule of Evidence 502, a powerful, but under-used tool that can mitigate risk and significantly reduce the cost of protecting attorney-client privileged and work product protected information.
