Howard Stern's lawsuit against his employer SiriusXM over unpaid bonuses is back in the legal system, as the New York Daily News reports new paperwork was filed on Monday with the New York Supreme Court Appellate Division. According to the paper, the new filing will put an appeal into motion against an April court ruling that dismissed the charges from Stern and his production company.

Sources tell the Daily News that the filing has yet to be processed, but could be ready by week's end. Stern, his One Twelve Inc. production company and his agent Don Buchwald appealed the ruling in April as well.

Stern's camp originally filed suit in March of 2011, claiming the satcaster owed Stern a series of bonuses that were tied to certain subscriber numbers. Stern and Buchwald believed that the merger of Sirius and XM, which boosted the company's subscriber totals, should have caused the bonus clauses to kick in. Stern had said on-air that these bonuses could have been worth hundreds of millions of dollars.
