As a resource to 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 time frame. This report covers the time period from January 28 – February 3, 2011, during which time 54 new class actions were filed in these courts. Labor law class action files approached the 50% mark, accounting for 25 of the new labor law class actions filed (46% of the total number of new class actions filed). And yet again, 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 claims, with 15 new filings (28% of the total number of new class actions filed).
