In order to assist California class action defense attorneys in anticipating claims against which they may have to defend, we provide weekly an unofficial summary of legal categories for class actions 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. This report covers the time period of April 27 – May 3, 2007. We include only those categories that contain 10% or more of the class action filings during the relevant timeframe. Approximately 42 class action lawsuits were filed in these California state and federal courts during that time period, of which 20 involved employment law class action claims, which represents approximately 48% of the class actions filed during this time period. The only other category to break the 10% threshold consisted of alleged unfair business practice class actions, which include false advertising claims, with 7 new class action filings (17%).
