As a resource to California 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 past week, only 36 new class action cases were filed in these courts. True to the norm, more labor law class action lawsuits were filed than any other category in the weekly class action filings. This report covers the time period from May 18 – May 24, 2007, during which time 17 new employment-related class action cases (47%) were filed in the California state and federal courts listed above. Four securities fraud class action lawsuits were filed, accounting for 11% of the new class actions. No other category met the 10% threshold.
