The Cleveland Browns legal challenge in federal court over its proposed move from downtown to Brook Park should be tossed out, the Ohio Attorney General’s Office and City of Cleveland argued on Wednesday.

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.
