As a resource to California class action defense attorneys, 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 time period of November 9 – November 15, 2007, during which time 46 new class action lawsuits were filed in these courts. As a general rule, more labor law class action lawsuits are filed than any other category of cases, often by a wide margin. This again proved to be true, with 15 new class actions alleging employment law claims — only 33% of the total number of new class action filings this past week, but substantially more than the second closest group of cases. Antitrust class action lawsuits came in second with 7 new lawsuits (only 15% of the total number of new class actions filed), followed closely by unfair competition law (UCL) claims (which include false advertising claims) with 6 new filings (13%) and 5 new securities fraud class actions (11% of the new filings).
