To assist California class action defense attorneys anticipate the claims against which they will 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 June 29 – July 5, 2007, during which time 37 new class action lawsuits were filed in these courts. We repeatedly note that employment-based class action lawsuits usually lead the list of new class action filings by a wide margin, but last week new labor law class actions outstripped all other categories of new class action filings by its widest margin since we began reporting these statistics. This week suggests that the “phenomenon” may prove to be a trend, because out of these 37 new class action lawsuits, 22 (60%) involve employment-related claims. Unfair competition law (UCL) class action cases, which include false advertising cases, came in a distant second with 5 new class action lawsuits (14%), followed closely by 4 new securities class action cases (11%).
