To assist class action defense attorneys anticipate the types of claims against which they will have to defend in California, 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 11 – 17, 2010, during which time only 37 new class actions were filed in these California state and federal courts. Labor law class actions often account for more than half of the new class action filings in any particular week — but during this reporting period only 18 new labor law class actions were filed, representing a relatively low 49% of the total number of new class actions filed. The only other categories that managed to break the 10% threshold were class actions alleging violations of California’s Unfair Competition Law (UCL), which includes false advertising claims, with 7 new filings (representing 19% of the total number of new class actions filed) and class actions alleging violations of the Telephone Consumer Protection Act, with 5 new filings (representing 14% of the total number of new class actions filed).
