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. Because of the Thanksgiving holiday, this report covers the time period from November 20 – December 3, 2009, during which time 71 new class action cases were filed in these California state and federal courts. Labor law class actions often account for more than half of the total number of new class action lawsuits filed in California, and generally top this list by a wide margin. During this reporting period, there were 33 new class actions alleging employment-related claims (46% of the total number of new class actions filed). The only other category to break the 10% threshold involved class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims, with 17 new class action lawsuits (24% of the new class actions filed during the reporting period).
