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 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 August 22 – 28, 2008, during which time 39 new class action lawsuits were filed. Labor law class action lawsuits generally top the list of new class action filings in California state and federal courts, often by a wide margin. This past week, however, proved an exception to this pattern. During this reporting period, 14 of the new class action lawsuits (36%) alleged violations of California’s unfair business practices statute, which include false advertising claims. New labor law class action lawsuits came in a close second, with 13 new filings (33%). The only other category that satisfied the 10% threshold involved class action lawsuits alleging securities-related claims, with 4 new filings (10%).
