In order to assist class action defense attorneys anticipate the types of cases 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 April 17 – 23, 2009, during which time only 30, a relatively low number of new class actions, were filed. Labor law class action lawsuits generally top the list by a wide margin. During this reporting period, 16 of the new class actions involved labor law claims (representing 53% of the total number of new class actions filed during the past week). Only two other category met the 10% threshold: there were 5 new class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims (17%), and there were 3 new class actions alleging violations of federal securities laws (10%).
