More: In a 2-1 decision, the U.S. Court of Appeals sided with historic preservationists who sued to stop construction. The court said it would stay its own ruling for two weeks to allow the administration to appeal to the U.S. Supreme Court. "Whether or not a massive ballroom should be constructed is for Congress to decide and is not a matter for Executive self-help," the court wrote. This ruling does not even necessarily mean that the Defendants may not ultimately construct the ballroom. "What it does mean," the court continued, "is that the Defendants may not do so during the district court's expeditious litigation without securing Congress's authorization, as the Constitution and laws require."
