To assist class action defense attorneys anticipate the types of cases against which they will have to defend in California courts, 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 2 – 8, 2009, during which time 51 new class action cases were filed in these California state and federal courts. Class actions alleging employment-related claims generally top the list by a wide margin. This past week, 27 of the new class action lawsuits involved labor law claims (53% 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 10 new class action lawsuits (20% of the new class actions filed during the reporting period).
