The Trump administration has asked the Supreme Court to let construction of a new White House ballroom continue, appealing to the Justices after two lower courts ruled against it. Solicitor General D. John Sauer filed the emergency application, docketed as National Park Service v. National Trust for Historic Preservation, No. 26A203 [1]. The challenger, the National Trust for Historic Preservation, has until noon Eastern on Tuesday, August 18, to respond [1].
The order the government wants lifted came from Senior U.S. District Judge Richard Leon, who blocked above-ground construction [1]. A panel of the U.S. Court of Appeals for the D.C. Circuit upheld that block on August 7 [2]. The panel of Judges Millett, Rao, and Garcia split 2-1, with the opinion for the court filed by Judges Millett and Garcia and a dissent from Judge Rao [2].
The majority's reasoning is narrow and structural. Congress, the court wrote, holds "exclusive authority to regulate the construction and demolition of White House structures" [2]. On that basis the panel let stand the halt on a project it described as a "$400 million" ballroom, a plan to "build a 90,000 square-foot ballroom in President's Park" [2]. The panel did not order work stopped forever; it stayed its own ruling for fourteen days, writing, "We hereby stay this ruling for fourteen days" [2]. That two-week window is what pushed the case onto the Supreme Court's emergency docket this week.
The government's application reframes the dispute in the language of security rather than construction law. Halting the work, it argues, "will halt the ongoing construction of the integrated military complex, including a totally secure ballroom space, at the East Wing of the White House, which is vitally required by national security" [1]. It also tells the Justices the project is already "65% complete in its entirety" [1], a figure meant to show that stopping now wastes what is built.
On standing, the Solicitor General argues the Trust has no business in court at all. The challenge, he contends, rests on a member's "dislike" for the construction, a "subjective preference" that does not amount to the concrete injury the law requires to sue [1]. The Trust prevailed on that question at both the district and circuit levels, so the standing argument is now the government's route to a clean win: if the Justices agree the Trust cannot sue, the merits question about congressional authority never gets decided.
What the appeals court settled and what the Supreme Court is being asked to unsettle are different things. The D.C. Circuit answered a power question, ruling that this kind of building and demolition is Congress's to regulate [2]. The emergency application answers a timing question, asking the Justices to let the walls keep going up while that power question waits. The response deadline of August 18 is the next fixed point on the docket [1].
