In brief
In a 5‑4 decision, the U.S. Supreme Court cleared the way for President Donald Trump to continue building a $400m ballroom on the White House grounds. The ruling blocked lower‑court orders that would have halted construction and allowed the Trump administration’s emergency request to stand. The National Trust for Historic Preservation challenged the project, arguing the president lacked unilateral authority. The Court’s majority hold that the administration will likely succeed in showing irreparable harm and a balance of equities when it seeks to defend its claim of executive authority. Trump’s decision to demolish the historic East Wing last autumn marked the start of the controversial construction, sparking legal battles that now appear to be moving in favor of the president.
Supreme Court’s 5‑4 Ruling Allows Trump Ball‑Room Construction at White House
On 31 August 2026 the U.S. Supreme Court issued a 5‑4 decision that permitted President Donald Trump’s $400 million ballroom project to proceed on the White House grounds. The court overrode lower‑court rulings that had blocked construction of an above‑ground portion of the new addition.
The case began when the National Trust for Historic Preservation filed a lawsuit arguing that the president lacked unilateral authority to build the structure. The Court’s majority opinion noted that the Trump administration had shown it was likely to be able to prove it would suffer irreparable harm without a stay and that the balance of equities tipped in its favour.
Chief Justice John Roberts, a conservative, joined three dissenting liberal justices in a brief statement that “construction is likely unlawful.” They argued that Congress has explicitly prohibited construction of any building on federal grounds in the capital without “express authority.” The dissenting panel noted that no law granting such authority had been enacted.
Trump has long maintained that a larger events space and the addition of a military complex are essential for the White House’s function and security. The Trust contended that the construction would cause irreversible damage to a historic landmark, yet the Court found the Trust did not have standing to challenge the project.
With this ruling, the Trump administration can resume demolition of the historic East Wing and continue work on the new ballroom, a move that will likely become a focal point of ongoing discussions about historical preservation and executive authority.
