Lawyers from Boies, Schiller & Flexner and Mayer Brown are representing the District of Columbia Council in its fight with the mayor over management of the city’s budget.

The council filed a lawsuit Thursday morning in D.C. Superior Court against Mayor Vincent Gray (D) and the city’s chief financial officer, James DeWitt. The council wants a court order forcing the mayor to comply with a new law allowing the city to spend locally raised dollars without explicit approval from Congress.
