To assist defense attorneys in California predict the type of cases against which they may 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 timeframe. This report covers the time period from August 10 – August 16, 2007, during which time 46 new class action cases were initiated in these California state and federal courts. Generally, class action cases alleging employment law violations top the list, often by a wide margin, and this past week labor law class actions surged from the prior week.
