The U.S. General Accounting Office (GAO) is an independent, nonpartisan agency that works for Congress. GAO is often called the "congressional watchdog" because it investigates how the federal government spends taxpayer dollars.
The GAO works for congress and has no authority to make it's request of Cheney.
Of course the case which is the topic of this thread has nothing to do with Cheney or the GAO. I agree with the judges decision to enforce a reasonable timetable on the production of documents.

Because of the Federal Advisory Act, they can request this of Cheney and they can file suit against him also, even if it is a civil suit.
