Jonathon Brandmeier, a former morning host at WLUP-FM 97.9, owes his former talent agent about $312,000, according to a lawsuit filed last week.

Lisa Miller and her Chicago-based Miller Broadcast Management Inc. went to Cook County Circuit Court to enforce a June 10 arbitrator’s decision to award the company $185,000 in unpaid fees plus more than $100,000 in attorney’s fees and interest.Brandmeier lost his radio show on WLUP last November with three months left on his contract when the station decided not to renew him. The station, which had been Brandmeier’s home from 1983 to 1997, brought him back in 2005.

He could not be immediately reached for comment.

Miller Broadcast entered into a contract to represent Brandmeier in 2003, according to the suit. At some point, a dispute arose regarding unpaid fees. The company had to go to arbitration to resolve it, according to the terms of the agreement.

Brandmeier has not complied with the arbitrator’s ruling. Miller Broadcast is entitled to interest in the amount of $29.60 per day since the June 10 ruling, the suit said.
