In order to assist class action defense attorneys anticipate the types of class actions against which they will have to defend in California, we provide weekly, unofficial summaries of the legal categories for new class action lawsuits filed in the state and federal courts located in 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 the period from March 13 – 19, 2009, during which time 46 class actions were filed. Labor law class actions generally top this list, and usually account for more than 50% of the total number of new class actions filed each week. While employment-related class actions did not meet this 50% mark, they did continue to hold the top spot among new class actions. In this reporting period, 22 new labor law class action lawsuits were filed, representing 48% of the total number of new class actions filed during the past week. Only one other category met the 10% threshold, as there were 8 new class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims (17%).
