Tener v. Cremer, 931 N.Y.S.2d 552 (N.Y. App. Div. 2011)

Key Insight: Addressing the obligation of a non-party to produce ESI that was deleted through ?normal business operations?, the court found that the Naussau Guidelines provided the best approach to determine the third party?s obligation to produce allegedly inaccessible data where the guidelines called for a cost/benefit analysis involving the difficulty of the production at issue; court found plaintiff had shown ?good cause? for needing the requested ESI but that there was insufficient evidence of the non-party?s alleged burden of production (including, for example, whether the at-issue ESI had actually been deleted, whether it could actually be retrieved, the cost of such retrieval, etc.) and thus remanded the case to the Supreme Court for ?a hearing on whether the information plaintiff seeks is ?inaccessible? and hence whether [the non-party] has the ability to comply with the subpoena; the appellate court reversed the Supreme Court?s ruling holding the non-party in contempt for failure to comply with a judicial subpoena
