In an unsigned order on Monday, the five-justice majority said the preservation group lacked standing to sue and that lower courts had likely exceeded their authority in blocking the project. The administration had argued it would suffer irreparable harm without a stay. Construction of the ballroom, which includes demolition of the historic East Wing of the executive residence, began last autumn and is expected to be substantially complete by November 2026, with full completion by August 2028.
Chief Justice John Roberts, in a dissenting opinion joined by the three liberal justices, wrote that 'construction is likely unlawful' because Congress has not approved the project. The dissent did not decide on the merits but argued the lower courts acted properly.
The National Trust for Historic Preservation had filed the legal challenge, arguing the president did not have unilateral authority to proceed with construction. The preservation group has not indicated whether it will pursue further appeals.
Critics have noted that the Trump administration's aggressive timeline on the ballroom and other initiatives aims to outrun judicial review, a pattern that raises broader questions about executive power.
