To assist California defense attorneys in anticipating the claims against which they may have to defend, we provide weekly, unofficial summaries of the legal categories for new class actions 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. Employment law class action cases generally top the list, and this proved true yet again. This report covers the time period from March 30 – April 5, 2007, during which time approximately 53 class action lawsuits were filed in these California state and federal courts. Labor law class action filings accounted for 36% of these cases, with 19 new class action lawsuits. Next came unfair competition law (UCL) claims, which include false advertising class action cases, with 8 new class actions (15%), and class actions under the federal Fair and Accurate Credit Transactions Act (FACTA), also with 8 new filings. The only additional category to break the 10% threshold involved 6 new antitrust class action cases (11%).
