To assist class action defense attorneys anticipate the types of cases against which they will have to defend in California state and federal courts, we provide weekly, unofficial summaries of the legal categories for new class action lawsuits filed in the state and federal courts located in 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 preceding week. This report covers the period from December 12 – 18, 2008, during which time 43 new class action lawsuits were filed. Class action lawsuits alleging employment-related claims generally top the list of the new class action filings by a wide margin. This past week did not disappoint. During this reporting period, 22 new labor law class action lawsuits were filed, representing 51% of the total number of new class actions filed. The only other category to meet the 10% threshold involved class actions alleging violations of California’s Unfair Competition Law (UCL), which include false advertising claims, with 8 new filings (19%).
