The White House ballroom preliminary injunction requires the government to pause above-ground construction while the courts decide whether Congress expressly authorized the project. It is temporary relief, not a final ruling that the ballroom can never be built.
The D.C. district court granted the National Trust's request on March 31, 2026, after finding the project likely unauthorized. The central dispute is whether general authority to improve the White House can satisfy a law requiring express congressional approval for structures on federal park grounds.

What must a party prove for a preliminary injunction?
A preliminary injunction preserves the situation while a lawsuit proceeds. The party seeking one must make a clear showing on four points: These requirements demand more than showing that a lawsuit raises serious questions.
The national Trust had to establish probable harm that a later judgment could not adequately repair. The district court also found preliminary "associational standing," meaning the organization could sue based on harm to a member. That member regularly visits President's Park and alleged a concrete aesthetic injury from the planned construction, according to the February 26 district court decision.

Why does congressional authorization matter?
The statutory centerpiece is 40 U.S.C. § 8106. It says a building or structure may not be erected on federal reservations, parks, or public grounds in Washington, D.C., without express authority from congress, as shown in the House Office of the Legislative Counsel's text of Section 8106.
"Express" authority is important. The court's preliminary analysis did not treat broad power to maintain or improve the white House as automatically equivalent to specific permission to erect a new structure on protected federal grounds. That distinction explains why funding or administrative control alone may not resolve the case. The key question is whether Congress clearly authorized this type of construction at this location.
What authority does the administration claim?
The administration relies on 3 U.S.C. § 105(d). That provision authorizes appropriations for the White House's care, repair, alteration, and improvement, according to the official statutory text.
The difficulty is that Section 105(d) does not itself expressly authorize construction on federal park grounds. The litigation therefore turns on how the two statutes work together: whether alteration and improvement authority is enough, or whether Section 8106 demands separate, project-specific congressional approval. The preliminary injunction reflects the courts' current assessment of that argument. It does not prevent Congress from later granting the authorization that the courts found likely missing.
What work does the injunction stop?
The injunction does not halt every activity connected to the site. The district court limited it to above-ground ballroom construction.
The court allowed below-ground national-security facilities to proceed. It also permitted work strictly necessary for presidential and site security, as specified in the April 16 district court order. That boundary matters when evaluating claims that construction has either "stopped" or "continued." Below-ground security work can continue without authorizing the above-ground ballroom itself.
Where does the case stand?
On August 7, 2026, a divided D.C. Circuit panel upheld the injunction during expedited litigation. The panel concluded that the administration could not build the ballroom without congressional authorization while the case proceeded.
The appeals court temporarily stayed its ruling for 14 days. The administration asked the Supreme Court on August 14 to allow construction during the appeal, and the National Trust filed its opposition on August 18, according to the Associated Press account of the Supreme Court dispute. Readers tracking later developments should distinguish three separate events: a ruling on temporary construction, a final judgment on the statutes, and any later congressional authorization. A Supreme Court decision about whether work may continue during the appeal would not necessarily settle whether the ballroom is lawful on the merits.
