(CBS) — The bitter fight between the Cubs and the Wrigley rooftop owners continues.

Owners of eight rooftop clubs across from Wrigley Field have filed a new lawsuit against the city. They want the court to overturn the city’s approval of the team’s plan to renovate Wrigley Field, notably the landmark commission’s decision that will enable the Cubs to erect as many as seven signs in the outfield.

The rooftop owners say that part of the $575 million plan to renovate Wrigley Field and the surrounding area would cripple their business because it would block their views. They contend the decision violates a contract they signed with the Cubs in 2004 that guarantees views into the ballpark while the rooftops give the organization 17 of their annual revenue.

Back in July, Cubs spokesman Julian Green told 670 The Score that the team is still willing to negotiate with the rooftops, but they won’t ever go back to the original two-sign proposal. After talks reached an impasse with the rooftop owners, the Cubs went forward with their more ambitious seven-sign proposal last spring and then received approval this summer.

The Cubs tell CBS 2 they have no comment on this most recent lawsuit.
