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 November 13 – 19, 2009, during which time 48 new class action cases were filed in these California state and federal courts. Labor law class actions almost always top this list, often by a substantial percentage and often accounting for well over half of the total number of new class actions filed in these California courts. During this reporting period, however, only 16 of the new class action lawsuits involved employment-related claims (representing a comparatively low 33% of the total number of new class actions filed). The only other categories to break the 10% threshold involved class actions involving securities claims, with 13 new lawsuits (27% of the total number of new class actions filed), and class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims, with 9 new class action lawsuits (19% of the new class actions filed).
