To assist class action defense attorneys anticipate the types of claims against which they will have to defend in California courts, 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 October 1 – 7, 2010, during which time 60 new class actions were filed in these California state and federal courts. While the percentage of new labor law class actions has been down recently, during this reporting period that percentage again rose above 50% of all new class actions filed in these courts. For this reporting period, 33 new labor law class actions were filed, representing 55% of the total number of new class actions filed. The only other category to break the 10% threshold involved claims under California’s Unfair Competition Law (UCL), which includes false advertising claims, with 13 new filings (representing 22% of the total number of new class actions filed).
