Supreme Court greenlights Trump’s White House ballroom construction

Sun Sep 06 2026 12:01:31 GMT+0000 (Coordinated Universal Time)

The US Supreme Court has cleared the way for President Trump to build a new $400m ballroom at the White House, after a 5‑4 decision that overruled lower‑court bans.

The Supreme Court’s 5‑4 ruling in late August allows President Donald Trump to continue building a new white‑house ballroom, a $400 million project that has drawn criticism from historic preservation groups. The Court lifted lower‑court orders that had stopped construction of the ballroom’s above‑ground portion, effectively endorsing the administration’s emergency request. While the justices ruled that the president likely has standing to proceed, dissenting opinions warned that Congress has not granted explicit authority for such a building. Trump has long argued the ballroom is needed for larger events and security upgrades, but the National Trust for Historic Preservation cites irreversible damage to the historic East Wing. The decision marks a rare win for Trump amid a contentious political climate, as the court’s judgment allows construction to resume while a lawsuit aiming to halt the project proceeds to the full court.

Construction continues on a new helipad on the South Lawn of the White House and the East Wing ballroom on 24 August 2026 in Washington DC.

The US Supreme Court has ruled that construction of a $400m ballroom at the White House can go ahead, handing a win to President Donald Trump.

In a 5‑4 decision, the justices granted the Trump administration’s emergency request, blocking lower‑court rulings that would have halted construction of an above‑ground portion of the project.

The National Trust for Historic Preservation filed the legal challenge, arguing that the president did not have unilateral authority to proceed with construction.

Trump demolished the historic East Wing of the executive residence last autumn to begin building the ballroom.

On Friday, the high court had temporarily allowed construction of the White House ballroom to move forward. Chief Justice John Roberts issued a stay, permitting the project to continue while the full court considered the lawsuit aiming to halt it entirely.

Roberts, a conservative, had joined three liberal dissenting justices to write that “construction is likely unlawful.” The dissent stated that Congress explicitly prohibits construction of any building or structure on federal grounds in the capital without express authority of Congress.

They added that no law resembling “express authority” for the Executive’s construction had been passed. In the signed order, the five judges who cleared the way for construction argued the administration would likely succeed in showing that the Trust lacked standing to challenge the East Wing project, that irreparable harm would be inflicted without a stay, and that the balance of equities tipped in favor of the administration.

Trump has long claimed the White House needs a larger events space and, more recently, that it is vital for his security. The National Trust for Historic Preservation contended that the construction would cause irreversible damage to the historic landmark.
