WASHINGTON — The Supreme Court on Monday, Aug. 31, 2026, voted 5-4 to let the Trump administration keep building a White House ballroom while a historic-preservation lawsuit proceeds, staying a lower-court injunction that would have halted most above-ground work. Chief Justice John Roberts, joined by Justices Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson, dissented. Roberts wrote that the construction is "likely unlawful."

The unsigned per curiam in National Park Service v. National Trust for Historic Preservation, No. 26A203, is explicit about what it does not do: "Today, we do not pass upon the legality of the government's East Wing project. We conclude only that, based on the submissions before us, the government is likely to prevail in showing that the Trust lacks Article III standing to challenge the project in federal court."

The National Trust sued after the administration demolished the East Wing and began a roughly 90,000-square-foot ballroom and underground complex without a statute that looks like specific approval from Congress. U.S. District Judge Richard Leon enjoined further above-ground construction except work "strictly necessary" for security; the D.C. Circuit affirmed on Aug. 7. Roberts had issued a temporary administrative stay on Aug. 21. Monday's order keeps the injunction stayed pending a government petition for certiorari.

The Trust's standing theory rested on a declaration from board member Alison K. Hoagland, a Washington preservationist who said she visits the neighborhood about once a month and would be injured in her "aesthetic, cultural, and historical interests" by the ballroom's scale. The majority said "mere offense, disagreement, or distaste does not qualify as a concrete and particularized injury," and that the Court has not found standing "in circumstances like these before."

Roberts's dissent starts from a statute, not a vibe. Congress, he wrote, has "plenary constitutional authority over the District of Columbia and federal property" and has barred any "building or structure … on any reservation, park, or public grounds of the Federal Government in the District of Columbia without express authority of Congress" (40 U.S.C. §8106). The ballroom is such a structure on President's Park. "Yet Congress has not passed any law resembling 'express authority' for the Executive's construction of it." He rejected the government's citations to ordinary White House maintenance money — $2,475,000 this year — and to the Park Service's duty to conserve historic objects. "With the Court's rejection of Hoagland's standing today," he wrote, "it now is the case that 'I want to look at a crocodile' can adequately answer the ever-critical 'what's it to you?' question of Article III standing, while 'I want to look at the White House' cannot."

The administration told the Court the project was 65 percent complete as of Aug. 24, with a 250-person crew working 20 hours a day, seven days a week, NBC News reported. The White House has called it a privately funded $400 million "military complex"; Secret Service money has already gone to some security work, NBC said, and the private-donation claim has been disputed. Justice Department lawyers argued national-security harm from stopping a "single, coherent" project. Trump, on Truth Social, said the Court had ruled "in favor of the Ballroom/Military Complex being built without any further contingency, doubt, or threat."

Brent Leggs, the Trust's president, said the majority "did not weigh in on whether the ballroom project was in fact legal" and that each president is "a temporary steward of the People's House." The stay can expire if certiorari is denied. Until then, the building goes up, and the legal question Roberts flagged — who may sue when the executive builds on federal ground without Congress — is the holding.
