In United States v. Ruehle, Slip. Op. (9th Cir. Sept. 30, 2009), the Ninth Circuit reversed the suppression order issued in United States v. Nicholas, 606 F.Supp.2d 1109 (C.D.Ca. Apr. 2009) based on the lower court’s application of the wrong privilege standard, but left intact that portion of the Nicholas opinion suggesting that attorneys need to provide and document complete Upjohn warnings and avoid dual representations absent a written conflict waiver. Shari Brandt and James Walker have written a short memorandum examining the important distinction drawn in Ruehle between application of federal and state privilege rules, and the Ninth Circuit’s reinforcement of the lessons learned from Nicholas.
