Consumer Action

Consumer Action maintains this listing of notable class actions so that interested consumers can learn more, join a pending action or make a claim. You can sort the listing three ways—actions or settlements that are (1) open to claims, (2) pending or (3) closed—or use the calendar to search for upcoming claims deadlines. We invite information about pending and ongoing class actions. Email .(JavaScript must be enabled to view this email address). Want to start a class action? For tips, click here.
