To aid California class action defense attorneys in anticipating claims against which they may have to defend, each week we provide an unofficial summary of legal categories for class actions 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. This report covers the time period of from December 28, 2006 – January 4, 2007. We include only those categories that contain 10% or more of the class action filings during the relevant timeframe. Approximately 39 class action lawsuits were filed in these California state and federal courts during that time period – excluding the eleven (11) antitrust class action cases involving British Airways et al. transferred into California by the Judicial Panel on Multidistrict Litigation (MDL). Eleven (11) of the weekly class action filings (28%) alleged violations of state and/or federal labor laws. Class action cases alleging violations of California’s unfair competition law (UCL) came in second with 6 new class actions (15%). The only other category of cases to break the 10% threshold consisted of alleged violations of the federal Fair and Accurate Credit Transactions Act (FACTA) – class action defense attorneys will face 5 new cases involving that area of law, which represents approximately 13% of the class actions filed during this time period.
