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 July 16 – 22, 2010, during which time 53 new class actions were filed in these California state and federal courts. Labor law class actions again took the top spot, with 23 new class actions (representing 43% of the total number of new class actions filed). The only other category to break the 10% threshold mirrored the class actions which broke the threshold last reporting period, involving alleged violations of California’s Unfair Competition Law (UCL), which includes false advertising with 10 new filings (representing 19% of the total number of new class actions filed).
