INDIANAPOLIS -- Proceeds from an auction of items from the RCA Dome should be used to pay debt still owed for the stadium, not to two nonprofit organizations as is currently planned, a lawsuit says.

The lawsuit, filed Monday by attorney Adam Lenkowski on behalf on Marion County taxpayers, seeks an injunction that would keep the Indiana Sports Corp. and Indianapolis Colts Foundation from getting proceeds from the auction.

The dome is scheduled to be demolished this year, and an online auction for dome memorabilia began last week. Lenkowski said the dome, which was built in 1984, was financed by taxpayer money and debt that hasn't been paid.

"The people that actually paid for the dome have no say whatsoever in where the money is going," Lenkowski told 6News' Renee Jameson.

The dome's operator, the Capital Improvement Board, said it gave the memorabilia --including stadium seats, pieces of turf and player lockers -- to the two nonprofits in part because the CIB doesn't have the manpower to run an auction. The nonprofits are running the auction, and therefore they should get the proceeds, the CIB said.

The suit contends that the CIB shirked its financial responsibility to Marion County residents by allowing the items to be sold by the nonprofits.

Lenkowski said the remaining debt for the RCA Dome was consolidated with the debt owed for the new Lucas Oil Stadium, which is scheduled to open this summer.

"We're still paying off the old dome, and now all of the sudden we're paying off this new (stadium)," he said.

The lawsuit contends that if the auction proceeds aren't used to pay off the dome debt, they should somehow be returned to Marion County taxpayers.

The RCA Dome was built in 1984 for $80 million. The new Lucas Oil Stadium is scheduled to be complete by Aug. 15, about a week before the Indianapolis Colts are scheduled to play a preseason game there.
