Cleveland’s fight to keep the Browns from moving from downtown and 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.

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.
