Supreme Court and Eleventh Circuit authority
District decisions bind no one. On the questions this decision raises, the Supreme Court decisions and the circuit's published decisions listed here bind this court; a circuit disposition marked nonprecedential was not published as precedent and is persuasive only.

Norton v. Southern Utah Wilderness Alliance, 542 U.S. 55
Supreme Court, June 14, 2004. Section 706(1) and mandamus reach only a discrete agency action that the agency is legally required to take, so a court cannot compel programmatic improvements or action the law leaves to agency discretion.
