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 two-week period of January 25 – January 31, 2008, during which time 46 new class action lawsuits were filed. New class action cases alleging employment-related claims generally top this list, and this past week was no exception as 22 new labor law class actions were filed during this time period (48% of the total number of new class action lawsuits filed). New antitrust class action complaints came in a distant second with 7 new filings (15%), closely followed by class actions alleging violations of California’s unfair competition law (UCL), which include false advertising claims, and class actions alleging violations of federal securities laws, each with 5 new class action filings (11%).
