The developer tasked with constructing the Judge Doyle Square project in downtown Madison sued the city on Monday, according to court documents.

Beitler Real Estate Services LLC, a Chicago-based firm, sued the city in the Eastern Division of the U.S. District Court for the Northern District of Illinois.

The Madison Common Council unanimously passed a resolution last month approving an additional $11 million of public funds to complete the downtown development project. The extra money helps to carry out a plan to transform the former Government East parking garage and the space behind the Madison Municipal Building into apartments, retail space, a hotel and underground parking.

Beitler was in charge of a structural slab called “the podium.”

The developer alleges in the complaint that it was not consulted in the city’s unilateral proposal to the finance committee, which Beitler says violates their contract with the city.

The lawsuit asks the court to force the city to halt construction on the podium.
