As a resource to California class action defense attorneys, 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 17 – August 23, 2007. A total of 53 new class action lawsuits were filed in these California state and federal courts were filed during that time period. New class action cases alleging employment law violations frequently top the list by a wide margin, and this was certainly true this past week. Twenty-two (22) new labor law class actions were filed this past week, representing 42% of the total number of class actions filed. No other category came close, and indeed no other category satisfied the 10% threshold. We note, however, that two categories tied for second with only 5 new cases each — antitrust class actions, and product liability class actions.
