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 relevant timeframe. This report covers the time period from June 18 – 24, 2010, during which time only 39 new class actions were filed in these California state and federal courts. While labor law class actions generally top the list by a wide margin — often accounting for more than half of the new class action filings in any particular week — for the past weeks new labor law class actions accounted for less than 50% of the total number of new class actions filed. This past week, however, class actions involving employment-related claims against exceeded 50% with 21 new filings (54%). The only other category to break the 10% threshold involved class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising with 11 new filings (representing 28% of the total number of new class actions filed).
