As a resource to California class action 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 report covers the time period from August 13 – 19, 2010, during which time 56 new class actions were filed in these California state and federal courts. Labor law class actions generally top the list often accounting for more than half of all new class actions filed in these courts, but a surge in ADA class action filings coupled with balanced filings among several other categories caused employment-related class action cases to fall below 50%. During this reporting period, 22 new labor law class actions were filed, representing only 39% of the total number of new class actions filed. The only other category to break the 10% threshold involved claims under the American’s with Disabilities Act (ADA), with 16 new filings (representing 29% of the total number of new class actions filed).
