To assist California class action defense attorneys anticipate the types of cases 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 time frame. This report covers the time period from February 4 - 10, 2011, during which time 65 new class actions were filed in these courts. Prior to this year, labor law class action routinely accounted for more than half of the new class actions filed each week, but this year that has not been true. During this reporting period, 29 new labor law class actions filed (45% of the total number of new class actions filed). 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 16 new filings (25% of the total number of new class actions filed).
