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 case against the Cleveland Browns ownership after proposed departure from Huntington Bank Field.

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.
