United States v. Cinergy, Corp., 2009 WL 6327414 (S.D. Ind. Nov. 10, 2009)

Key Insight: Inadvertent production of privileged material by third party pursuant to subpoena waived defendants? privilege protection where third party?s disclosure was found to be tantamount to defendant?s disclosure because of the nature of their relationship and where defense counsel failed to take any steps to prevent the production of privileged materials despite being asked specifically if privilege issues were implicated in the production (to which he answered ?no?) and despite the low volume of materials produced; court noted that although there was no legal obligation for defendants to conduct a post-production review, ?had [they] done so, they might well have noticed the email at issue before Plaintiffs did, and the result in this case might have been different.?
