As a resource to defense attorneys who defend class actions in California, we provide weekly, unofficial summaries of the legal categories of 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 March 21 – 27, 2008, during which time 38 new class action lawsuits were filed (down substantially from the 58 new class action filings of the preceding week). Readers of this Blog know that class action lawsuits alleging labor lawclaims almost always top this list by a wide margin, and this past week was no exception. During the past week, 18 new class actions were filed alleging employment-related claims (47% of the total number of new class action lawsuits). Only two other categories managed to break the 10% threshold for this class action report: California unfair competition law (UCL) class action cases,which includes class actions alleging false advertising claims, with 10 new filings (26%), and federal antitrust class actions, with 4 new filings (11%).
