Rooftop owner sues Chicago's Landmarks Commission in effort to block Wrigley Field changes

The owners of eight rooftop clubs overlooking Wrigley Field have filed a lawsuit to overturn Chicago's approval of the Cubs' plan to revamp the century-old ballpark.

The lawsuit filed Thursday in Cook County Circuit Court asks a judge to reverse the city's action, saying it broke its own rules and deprived them of their property rights without due process. The lawsuit names the Commission on Chicago Landmarks and its members, as well as the city.

The commission in July approved seven electronic signs, including a left field Jumbotron, expansion of the bleachers and relocation of the bullpens.

Rooftop owners maintain the plan violates a revenue-sharing agreement that prevents the team from taking actions that block their views.

Chicago law department spokesman John Holden has refused to comment on the lawsuit
