The Trump administration on Friday asked the U.S. Supreme Court to allow the White House to resume construction on its $400 million ballroom project while it appeals a lower court’s order to halt the work.

Trump’s solicitor general petitioned the high court to suspend last week’s order. The filing seeks to lift the injunction so that work on the project can continue during the appeals process.

The request comes after the lower court blocked the construction last week. Administration officials have maintained that the ballroom project is necessary for official White House functions and events.

The Supreme Court petition represents the latest step in the legal dispute over the project. If granted, the emergency relief would permit crews to restart work immediately pending further court review.

The $400 million ballroom has been a priority for the administration. Construction had been underway before the lower court intervened. The solicitor general’s filing argues that the project should proceed without further delay.

Legal observers expect the high court to consider the request in the coming days. The case highlights ongoing tensions between the executive branch and judicial oversight of White House improvements.
