Non-Party E-Discovery Obligations in New York – A Question of Proportionality

In a rare New York State appellate decision concerning e-discovery, the First Department took the opportunity to address claims by a subpoenaed nonparty of inaccessibility of electronically stored information (ESI). The case, Tener v. Cremer, 2011 N.Y. Slip op. 6543 (1st Dep’t 2011), involved an alleged defamatory post originating from one of New York University’s computers. Plaintiff served NYU with a subpoena seeking identification of persons who accessed the Internet on a certain date via a certain IP address.
