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 30 – December 6, 2007, during which time 52 new class action lawsuits were filed. It is rare that labor law class action cases do not top this list, and this past week was no exception. During this past week, 19 new class actions alleging employment law claims were filed, representing 37% 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 second with 13 new filings (25% of the total). The only other category to meet the 10% threshold involved class actions alleging violations of federal securities laws with 6 new cases (12%).
