To aid 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 the time period of November 16 – November 29, 2007, during which time 92 new class action lawsuits were filed. New labor law class action cases routinely lead this lead, and that pattern continued. During the relevant time period, 38 new class actions alleging employment law claims were filed, representing 41% of the total number of new class action filings. Class actions alleging violations of California’s unfair competition law (UCL), which include false advertising claims, came in a distant second, with 22 new filings (24% of the total). The only two other categories to crack the 10% threshold involved class actions alleging violations of securities laws and antitrust laws, with 10 and 9 new cases (11% and 10%), respectively.
