In January 2017, HSR filed a wage and hour class action lawsuit against Tesoro Refining & Marketing Company, LLC, et al. in the United States District Court for the Northern District of California. Subsequently, a second-class action lawsuit was filed, alleging similar causes of action. On September 14, 2017, District Court Judge Jon S. Tigar appointed HSR as interim lead counsel over both cases. Judge Tigar concluded that HSR would “fairly and adequately represent the interests of the class” after finding that HSR had done extensive work identifying, investigating, and prosecuting the potential claims and had experience handling complex litigation and knowledge of the applicable law.
