A three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit put on hold a preliminary injunction issued a day earlier by U.S. District Judge Richard Leon, granting the Justice Department’s request for interim relief while the appeal proceeds. The panel scheduled oral arguments for June 5 to determine whether construction should remain paused during the broader legal review.

The appeals court’s brief order did not address the underlying legal merits of the dispute, which centers on whether the executive branch had the authority to demolish the historic East Wing and proceed with new construction without explicit approval from Congress.

The lawsuit was filed in December by the National Trust for Historic Preservation against the Trump administration and several federal agencies. The group argued that the demolition of the East Wing and the planned ballroom project violated federal preservation laws and exceeded the authority of both the president and the National Park Service.

Judge Leon, in his earlier ruling, sided with the plaintiffs’ argument that the project could not proceed lawfully without congressional authorization, prompting the administration to seek immediate relief from the appeals court to avoid construction delays.

The White House has defended the project as a privately funded initiative backed by donors, describing it as part of a broader effort to modernize the presidential residence while enhancing security infrastructure.

Trump has repeatedly framed the ballroom as a signature addition to the White House complex.Neither the National Trust for Historic Preservation nor the White House responded immediately to requests for comment following the appeals court’s decision issued late Friday.

The case highlights tensions between executive authority and statutory protections governing historic federal properties, with potential implications for how future administrations undertake structural changes to nationally significant sites.
