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 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 preceding week. This report covers April 4 – 10, 2008, during which time 42 new class action lawsuits were filed. Class actions alleging employment-related claims typically top the list of new class action cases by a wide margin. Last week, for example, 61% of the new class action filings were labor law class actions, while the next nearest category accounted for only 12% of the new class actions filed that week. During the time period covered by this post, 19 new class actions were filed alleging employment-related claims (45% of the total number of new class action lawsuits). Only two other categories managed to break the 10% threshold: class actions alleging violations of California’s unfair competition law (UCL) class action cases, which includes class actions alleging false advertising claims, and class actions alleging violations of federal securities laws, each of which had five (5) new filings (12%).
