First up among the runners-up, Stephen Broome and Rick Werder of Quinn Emanuel Urquhart & Sullivan helped their client Len Blavatnik put the final nail in the coffin of a $2 billion lawsuit that Russian billionaire Leonid Lebedev brought against him and business partner Victor Vekselberg. Lebedev claimed he’d been squeezed out of his rightful share of the proceeds of the sale of oil company TNK-BP to Rosneft. But New York’s Appellate Division, First Department last week upheld Quinn’s summary judgment win finding Lebedev had received his due as part of an earlier deal. John Williams of Williams & Connolly represented codefendant Vekselberg in the appeal.

Sean Berkowitz, Nicholas Siciliano, Whitney Weber and their team at Latham & Watkins helped Walmart this week beat back a securities class action claiming the company failed to adequately disclose that it was the subject of parallel civil and criminal investigations into prescription opioid sales. “At bottom, no investor could read Walmart’s disclosures regarding the investigations without understanding what was true—namely, that Walmart potentially faced losses if the investigation resulted in criminal charges or civil claims and that the scope of any such losses was indeterminate,” wrote Delaware Chief U.S. District Judge Colm Connolly. The team representing Walmart included Latham associates Jordan Mundell and Renatta Gorski and Delaware co-counsel Robert Whetzel and Raymond DiCamillo of Richards, Layton & Finger.
