As a resource to California class action defense attorneys, we provide weekly, unofficial summaries of the legal categories for new class action lawsuits filed in California state and federal courts in the Los Angeles, San Francisco, San Jose, Sacramento, San Diego, San Mateo, Oakland/Alameda and Orange County areas. We include only those categories that include 10% or more of the class action filings during the preceding week. This report covers May 9 – 15, 2008, during which time 54 new class action lawsuits were filed. Employment related class action lawsuits generally top the list of new class action cases by a wide margin. During the time period covered by this post, 28 new class actions were filed alleging various labor law violations (52% of the total number of new class action lawsuits during the past week). Only two other categories of class action lawsuits passed the 10% threshold — class action lawsuits alleging violations of California’s unfair business practice claims, which include false advertising claims, with seven (7) new class actions (13%), and class actions alleging antitrust violations, with six (6) new filings (11%).
