With an appellate practice split across Washington DC, Houston and San Francisco, Morgan, Lewis & Bockius LLP handles sophisticated appeals in state and federal courts nationwide. In two cases concerning the enforcement of arbitration agreements, Bryan Killian  and J. Warren Rissier secured a victory for Expedia’s subsidiary HomeAway as appellant at the Fifth Circuit, which unanimously reversed the district court’s judgments and affirmed the appellee’s obligation to arbitrate threshold arbitrability questions. Randall Levine led the team on scoring a win for appellant TDY and Allegheny Technologies in a Comprehensive Environmental Response, Compensation, and Liability Act (CERLA) case at the Ninth Circuit. Washington DC-based duo Levine and David Salmons successfully defended a gas company against tort claims related to a gas leak. William Peterson (Houston) and Thomas Peterson (San Francisco) are also noted. In June 2018, former co-head Allyson Ho departed to join the Dallas office of Gibson, Dunn & Crutcher LLP.
