Grant Thornton, LLP v. Office of the Comptroller of the Currency, 514 F.3d 1328 (D.C. Cir. 2008)

I must prepare closing arguments for the plaintiff above. I must prepare a "legal brief (report)" and argue for my client. This must be 5 to 7 pages long. I am unsure of how a legal brief should be prepared and where to put closing arguments.
