The Supreme Court allowed President Donald Trump’s White House ballroom construction to continue in a 5-4 ruling Monday, with Chief Justice John Roberts joining the court’s liberal justices in dissent and arguing the project is likely unlawful.

President Donald Trump’s planned White House ballroom can move forward after the Supreme Court lifted a lower-court obstacle Monday in a closely divided 5-4 decision.
The Supreme Court order permits construction to continue while litigation over the project proceeds, handing the Trump administration a significant victory in its dispute with the National Trust for Historic Preservation.
Chief Justice John Roberts dissented from the decision alongside the court’s liberal justices. Roberts said the construction is “likely unlawful,” even though he had previously granted the administration temporary relief that allowed work to continue while the full court considered the case.
The majority concluded that the federal government had demonstrated sufficient harm from the lower court’s injunction to justify allowing construction to proceed.
“The government has also established that it will likely suffer irreparable harm from the district court’s injunction and that the balance of the equities tips in its favor,” the court’s order stated.
The dispute reached the Supreme Court after months of litigation over whether the executive branch has authority to carry out the large-scale alteration of the White House complex without additional congressional approval or compliance with the requirements sought by preservation groups.
The National Trust for Historic Preservation sued the Trump administration over the project, and a federal judge earlier this year blocked construction.
The U.S. Court of Appeals for the District of Columbia Circuit subsequently concluded that Congress has authority over modifications involving federal property, keeping the administration’s plans entangled in the legal dispute.
The Justice Department then asked the Supreme Court to intervene.
Solicitor General John Sauer argued that the proposed ballroom serves functions extending beyond ceremonial events because the structure includes military-related infrastructure.
According to Sauer, the project incorporates a subterranean bunker and a rooftop drone port, leading the administration to characterize the facility in part as a military asset.
That argument became significant as the administration sought emergency relief from the injunction.
Last week, Roberts temporarily allowed construction to continue while the Supreme Court considered whether the lower court’s order should remain in effect.
Monday’s 5-4 decision replaced that temporary arrangement with broader permission for the administration to proceed while the underlying litigation continues.
The ballroom project dates to an announcement made by the administration last summer.
In July 2025, the White House formally announced plans for construction, presenting the project as a long-term solution to the executive mansion’s limited capacity for large state functions and other official gatherings.
“For 150 years, Presidents, Administrations, and White House Staff have longed for a large event space on the White House complex that can hold substantially more guests than currently allowed. President Donald J. Trump has expressed his commitment to solving this problem on behalf of future Administrations and the American people,” the Trump White House said.
The administration said the existing East Room cannot accommodate many of the large events hosted by the president and argued that the government has repeatedly been forced to install temporary structures outside the White House when hosting major gatherings.
“The White House is one of the most beautiful and historic buildings in the world, yet the White House is currently unable to host major functions honoring world leaders and other countries without having to install a large and unsightly tent approximately 100 yards away from the main building entrance. The White House State Ballroom will be a much-needed and exquisite addition of approximately 90,000 total square feet of ornately designed and carefully crafted space, with a seated capacity of 650 people — a significant increase from the 200-person seated capacity in the East Room of the White House,” the administration said.
Under the announced plans, the ballroom would provide approximately 90,000 square feet of space and seat as many as 650 guests.
That would more than triple the roughly 200-person seated capacity of the White House East Room.
Supporters of the project have portrayed it as a permanent alternative to the temporary tents historically used for state dinners and other events exceeding the White House’s indoor capacity.
Opponents have focused on historic-preservation requirements, federal-property law and questions over executive authority to make significant alterations to one of the country’s most historically important government complexes.
The National Trust for Historic Preservation’s lawsuit became the principal legal challenge to construction.
The Trump administration has strongly criticized that litigation.
Trump denounced those responsible for bringing the challenge in a Truth Social post and connected the dispute to the military elements the administration says are incorporated into the project.
“These are the TREASONISTS that brought the suit against the Military Complex. They revealed Top Military Secrets!” Trump said.
The president’s characterization reflects the administration’s position that information disclosed during litigation involved sensitive aspects of the facility’s design.
Monday’s ruling does not necessarily resolve every underlying legal question surrounding the ballroom.
Instead, it determines that construction can continue despite the lower court’s injunction while the broader dispute is litigated.
That distinction was highlighted by Roberts’ dissent.
Although Roberts previously issued the temporary stay that kept construction moving while the Supreme Court reviewed the administration’s request, he ultimately sided with the liberal justices against allowing the project to proceed under the broader order.
His conclusion that the construction is “likely unlawful” places him in direct disagreement with the five-justice majority over the administration’s entitlement to relief at this stage of the case.
The majority, however, focused on the immediate consequences of the injunction and found that the federal government had shown a likelihood of irreparable harm if construction remained blocked.
The ruling therefore allows work on Trump’s planned 90,000-square-foot ballroom to continue while the legal battle over congressional authority, historic preservation and control of modifications to the White House complex remains unresolved.
