Supreme Court rules in favor of Trump’s ballroom construction, while one conservative justice dissents
By Easton Martin | September 2, 2026
The U.S. Supreme Court has cleared the way for President Trump’s administration to continue construction of the planned White House ballroom while the underlying legal dispute proceeds through the courts. The justices ruled 5-4 on Monday to block a lower court order that had halted above-ground construction of the approximately $400 million project.
The ruling did not determine whether President Trump ultimately possesses the legal authority to construct the ballroom without congressional approval. Instead, the majority concluded that the National Trust for Historic Preservation likely lacked the legal standing necessary to challenge the project because its claimed injuries did not satisfy the constitutional requirement for an injury in fact.
The majority therefore allowed construction to continue while the broader litigation remains unresolved. The justices also determined that stopping construction at this stage could cause irreparable harm to the federal government, particularly given the project’s ongoing progress and the administration’s national security arguments.
Chief Justice John Roberts wrote the dissent and was joined by the court’s three liberal justices, Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson. The remaining five justices, Clarence Thomas, Samuel Alito, Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett, comprised the majority that allowed construction to proceed.
Roberts argued that the National Trust’s member had suffered sufficient aesthetic and historical injury to establish standing. He compared her connection to the White House and its historical architecture with established environmental cases where individuals have been permitted to challenge changes to particular places they regularly experience.
Roberts argued that the ballroom project itself is likely unlawful because Congress has not expressly authorized construction of the new structure on federal parkland in Washington.
