In an effort to assist California class action defense attorneys anticipate the claims against which they will have to defend, 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 relevant timeframe. This report covers the time period from July 6 – July 12, 2007. During this past week, 45 new class action lawsuits were filed in these California state and federal courts, of which twenty (20) involved labor law class action claims, representing 44% of the total number of new class action lawsuits filed during the week. Unfair competition law (UCL) class action cases, which include false advertising cases, came in second with 9 new class action lawsuits (20%). The only other category of new class action cases to break the 10% threshold alleged securities laws violations, with 6 new class action filings (13%).
