To assist defense attorneys anticipate the types of class actions against which they will have to defend in California state and federal courts, 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 the two-week period of January 18 – January 25, 2008, during which time 39 new class action lawsuits were filed. Class actions alleging employment-related claims generally top this list, often by a wide margin, and labor law class actions continued to hold the top spot this past week with 15 new filings (representing 38% of the total number of new class action lawsuits filed). The only other category to break the 10% threshold involved class actions alleging violations of California’s unfair competition law (UCL), which include false advertising claims, with 9 new class action filings (23%).
