In order to assist California defense attorneys in anticipating the claims 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 past week, only 30 new class action cases were filed in these courts. Predictably, more employment-related class action lawsuits were filed than any other category in the weekly class action filings. This report covers the time period from May 11 – May 17, 2007, during which time 11 new class action cases (37%) were filed in the California state and federal courts listed above. Seven securities fraud class action lawsuits were filed, accounting for 23% of the new class actions. The only other categories to break the 10% threshold were unfair business practices class action cases, which include false advertising claims, and fraud class action cases, each of which had 3 new cases filed (10%).
