The plaintiffs allege that California consumers were overcharged at the pump between 2012 and 2015 due to the defendants’ allegedly coordinated refinery shutdowns and other purported actions to restrict the supply of gasoline or create an appearance of a gasoline shortage in California. Persian Gulf Consolidated Antitrust Litigation (S.D.Cal.).
  • Led a litigation team that obtained summary judgment on all counts on behalf of a manufacturing company accused of contaminating a neighboring business’s groundwater.

  • Successfully defended a manufacturing company against Lanham Act false-advertising claims brought by a competitor, using discovery to formulate counterclaims that forced the competitor to drop its claims and agree to a $7.5 million-dollar settlement in the client’s favor and other corrective actions to create a level playing field; also persuaded court to sanction competitor’s in-house general counsel for unethical conduct in bringing claims against client.
