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 May 2 – 8, 2008, during which time 39 new class action lawsuits were filed. Readers know that labor law class actions almost always top the list of new class action cases, often by a wide margin, and this proved true yet again. During the time period covered by this post, 17 new class actions were filed alleging various labor law violations (44% of the total number of new class action lawsuits during the past week). The only other category of class action lawsuits that even managed to break the 10% threshold involved California unfair business practice claims, which include false advertising claims, with nine (9) new class actions (23%).
