In order to assist class action defense attorneys anticipate the 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 relevant timeframe. This report covers the time period from October 5 – October 11, 2007, during which time 29 new class action lawsuits were filed in these California state and federal courts. Last week, by contrast, more than 60 new class actions were filed in these courts. Generally, labor law class action cases lead the list by a wide margin, but the gap was necessarily narrower this past week in light of the smaller number of new class action lawsuits. During the time period at issue, 11 of the new class action filings involved labor law claims (38% of the total number of new class action cases), followed by seven (7) new antitrust class actions (24% of the total), mostly involving now-familiar claims against Korean Airlines. Two other categories of class actions managed to break the 10% threshold: four (4) involved new unfair competition law (UCL) class action filings, which include false advertising claims (14% of the total), and three (3) class actions alleging securities fraud (10%).
