  • Defeating class certification on behalf of large Southern California theme park in heavily-litigated case alleging meal and rest period, off-the-clock work, and regular rate claims;
  • Obtaining landmark appellate victory establishing that in California union employees subject to a CBA may enter into individual arbitration agreements containing class action waivers;
  • Prevailing on summary judgment/adjudication in harassment case on behalf of Fortune 200 company; and
  • Obtaining victory in appellate case establishing rule that a plaintiff in California may not appeal a denial of class certification under the so-called “death knell” doctrine if the case involves representative allegations under the Private Attorneys’ General Act.
