To assist class action defense attorneys anticipate the types of cases against which they will have to defend in California, 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 preceding week. This report covers July 3 – 10, 2008, during which time 40 new class action lawsuits were filed. Labor law class action lawsuits generally top the list, often by a wide margin, and this past week was no exception. Fully half of the new class action lawsuits filed during the past week were new labor law class actions; 20 such class actions were filed, representing 50% of the total number of new class action lawsuits. The only other categories that met the 10% threshold involved class action lawsuits alleging unfair business practice claims, which include false advertising claims, with six (6) new filings (15%), and class action lawsuits alleging violations of federal antitrust laws, with four (4) new filings (10%).
