Live Nation Entertainment’s board of directors was slapped with a shareholder derivative suit just one month after the company was sued by the Department of Justice for allegedly engaging in anti-competitive practices to monopolize the concert industry.

The complaint, filed by Bottini & Bottini in California’s Central District Court last Friday, argues that the defendants, including Live Nation CEO Michael Rapino, breached their fiduciary duties by failing to prevent antitrust violations and defying a 2010 consent decree prohibiting anti-competitive conduct. Other listed causes of action include abuse of control, unjust enrichment and violation of Section 14(a) of the Securities Exchange Act.
