Quinn Emanuel was disqualified from representing defendants after using information obtained from Mayers when it was a prospective client in a court filing against Mayers.  Mayers v. Stone Castle Partners, LLC, 43 Misc. 3d 1203(A) (N.Y. Sup. Ct. Mar. 28, 2014) (No. 650410/2013).  In May 2011, Mayers made an unsolicited call to a Quinn Emanuel attorney not involved in the instant litigation.  The two spoke for 30 minutes to an hour, but the attorney declined the representation because of an unrelated conflict.  The attorney who spoke with Mayers then discussed the call with defendants’ lead counsel (also at Quinn Emanuel) in the instant case, who used information obtained from Mayers, as well as details of Mayers’s call, in a court filing.  Even though defendants’ lead counsel did not seek this information from his colleague; the information obtained from Mayers was not particularly prejudicial; most of the facts were public knowledge at the time; and Mayers did not establish significant harm caused by Quinn Emanuel’s representation of defendants, Quinn Emanuel’s use of its attorney’s phone call with Mayers in a court filing mandated disqualification.
