Best known as a leader in shareholder class actions, Milberg Weiss filed a California consumer class action against five record labels Wednesday claiming that the audio discs they are selling with no-copy technology are misleading and defective.

In Dickey v. Universal Music Group, 275602, filed in Los Angeles Superior Court, Milberg Weiss requests that the defendants be enjoined from selling the compact discs and ordered to refund or replace them and/or label the products as inferior to standard CDs.
