The city of Cleveland has filed a lawsuit to stop the Browns from leaving their lakefront stadium and building a domed stadium in suburban Brook Park.

In August, the Browns announced their intentions to move to Brook Park, which is about 13 miles southwest of the current stadium, because it was “their most compelling option.” The team described it as a $2.4 billion project, which was later revealed to include a domed stadium.

The city has sued the team over the proposed move out of Cleveland to a domed stadium in Brook Park. The lawsuit arises under the Modell Law, which was enacted after the late Art Modell moved the Browns to Baltimore in 1996.

Mayor Justin Bibb is firing a law firm that was helping Cleveland raise funds for waterfront development as well as ballpark and arena repairs — since that law firm is now representing Brook Park as it tries to attract the Cleveland Browns.

Cleveland’s fight to keep the Browns from moving from their downtown home into a proposed dome in the suburbs has taken yet another legal turn.

The City of Cleveland returned fire Tuesday in its battle with the Haslam Sports Group. The city filed a lawsuit in the Cuyahoga County Court of Common Pleas asking for one of two things: that the team be offered for purchase by local buyers to prevent the move to Brook Park or that the company negotiate its exit from the city.
