The Supreme Court on 31 August 2026 granted the government’s emergency application to stay a preliminary injunction that had blocked most above-ground construction of a new White House East Wing. The unsigned per curiam in National Park Service v. National Trust for Historic Preservation in the United States, No. 26A203, stays the injunction entered by the U.S. District Court for the District of Columbia in case No. 1:25-cv-04316 pending the filing and disposition of a timely petition for a writ of certiorari. Chief Justice Roberts dissented, joined by Justices Sotomayor, Kagan, and Jackson. “Today, we do not pass upon the legality of the government’s East Wing project,” the Court wrote. It held only that the government is likely to show that the Trust lacks Article III standing and that the remaining stay factors favor relief.

The per curiam recites that the government began a project to replace the East Wing in October 2025 and finished demolishing the existing wing in December 2025. What is going up, the Court said, is a below-ground military installation and an above-ground ballroom. The D.C. Circuit’s opinion of 7 August 2026 described a 90,000 square-foot ballroom paid for by private funds. After the Trust sued, the district court on 31 March 2026, later clarified, allowed underground work to continue but enjoined further above-ground construction except as “strictly necessary” to protect the White House, the President, and staff. The D.C. Circuit stayed that injunction on 17 April 2026. On 7 August 2026, in No. 26-5123, Judges Millett and Garcia, with Judge Rao dissenting, affirmed the injunction and set the court of appeals’ stay to expire on 21 August 2026. The Chief Justice then issued an administrative stay so the full Court could act.

The Trust’s standing showing, as the Court described it, rested on a declaration from member Alison K. Hoagland, whom the dissent identified as an executive committee member. She lives in Washington, D.C., expects to visit the neighborhood around the White House “about once a month,” and said that viewing the finished ballroom would injure her “aesthetic, cultural, and historical interests” because of its “scale,” “height,” and “massing.” The Court treated that as mere offense, disagreement, or distaste, citing FDA v. Alliance for Hippocratic Medicine and Valley Forge. Distress at conduct one dislikes, it said, is not a concrete, particularized injury. Environmental aesthetic cases, it said, involved more than offense, such as abandoned fishing or swimming. Expertise does not create a standing carve-out. On the remaining stay factors, the majority pointed to declarations from the Director of National Intelligence, the CIA Director, the FBI Director, the Secret Service Director, the Secretary of State, the Secretary of Homeland Security, and the Secretary of the Army, among others. The Secretary of the Army said the ballroom’s “height and mass” are “crucial” to shield the underground installation “from kinetic impacts.” The Court said the equities are “not nearly in equipoise.” Should certiorari be denied, the stay terminates automatically. If it is granted, the stay lasts until the Court’s judgment is sent down.

Chief Justice Roberts wrote that the construction is “likely unlawful.” Congress has barred any “building or structure” on federal park or public grounds in the District of Columbia “without express authority of Congress,” 40 U.S.C. § 8106. The ballroom, he said, is being erected on President’s Park. Neither a $2,475,000 fiscal-year 2026 appropriation for Executive Residence “required maintenance” under 3 U.S.C. § 105(d)(1) (Pub. L. 119–75, 140 Stat. 451) nor the Park Service’s duty to conserve historic objects, 54 U.S.C. § 100101(a), is that authority, and the appropriation does not license “hundreds of millions of dollars in private donations” to tear down the East Wing. He analogized Hoagland’s injury to environmental aesthetic standing: “I want to look at a crocodile” can answer Article III’s “what’s it to you?” while “I want to look at the White House” cannot. “The White House is not just any building,” he wrote, and “Today’s decision is no victory for the separation of powers.” National Trust President and CEO Brent Leggs said the Trust was deeply disappointed, disagreed with the majority on standing, noted that legality was left open, and said each President is a “temporary steward of the People’s House” without unilateral authority to demolish and redesign it without Congress.
