Supreme Court Lets Trump Finish the White House Ballroom, 5-4, Without Deciding Whether It Is Legal

The Supreme Court on Aug. 31, 2026 granted the Trump administration's emergency request and blocked lower-court orders that had paused aboveground construction of the president's new White House ballroom. The unsigned 5-4 order held that the National Trust for Historic Preservation likely lacks standing to bring the suit, and expressly declined to decide whether the president may demolish the East Wing and build the ballroom without congressional approval. Chief Justice John Roberts joined the court's three liberal justices in dissent, writing that the construction "is likely unlawful." Administration filings said the project was 65% complete as of Aug. 24, with a 250-person crew working 20 hours a day.

Deciding the case on standing leaves unresolved whether a president may unilaterally reshape a federal landmark that a statute says requires the "express authority of Congress" for construction on federal land in Washington. Resolving an emergency application this way while the building rises means the physical outcome may be settled before any court reaches the constitutional question.

The Trust said the ruling "is not the final decision on the merits" and that its case continues. Trump said the ballroom will be completed in the summer of 2028.
