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 relevant timeframe. This report covers the time period from October 12 – October 18, 2007, during which time 50 new class action lawsuits were filed in these California state and federal courts. Labor law class action cases routinely lead the list by a wide margin, and this proved true yet again. During the past week, 23 new class actions were filed alleging employment law claims, representing 46% of the new class action filings for the week. Only two other categories managed to break the 10% threshold for this weekly class action report: eight (8) involved new unfair competition law (UCL) class action filings, which include false advertising claims (16% of the total number of new class actions), and five (5) involved securities fraud class actions (10%).
