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 10 – 16, 2009, during which time 39 new class actions were filed. Labor law class action lawsuits generally top the list by a wide margin and often account for more than half of the new class actions filed during the week. During this reporting period, only 17 of the new class actions involved labor law claims, which were sufficient to top the list of new class action filings in California courts but which represent a relatively low 44% of the total number of new class actions filed during the past week. Only one other category met the 10% threshold: there were 10 new class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims, representing 26% of the new class actions filed.
