The Supreme Court will close its doors to the public after running out of funds on October 18 during the government shutdown, but the justices will continue to hear cases, the high court announced.

Patricia McCabe, head of the court's Public Information Office, said in a statement emailed to reporters Friday afternoon that the court “expects to run out of funds on October 18" and "if no new appropriated funds are available" after that, "the Court will make changes to its operations to comply" with federal law.

"As a result, the Supreme Court building will remain closed to the public until further notice. The building will remain open for future operations. The Supreme Court will continue to perform essential business, including hearing oral arguments, issuing orders and opinions, prosecuting cases, and providing necessary law enforcement and building support for those operations,” the statement said.

When the government shutdown began on October 1, McCabe told ABC News that the court would continue regular operations, “relying on permanent funds not subject to annual approval, as in the past, to maintain its operations during brief gaps in annual appropriations.”

Under the Constitution, Supreme Court justices have life tenure, meaning they generally cannot be fired nor can their pay be reduced, even during a government shutdown.

The justices wrapped up their October arguments on the 15th, hearing arguments in a major voting rights case in Louisiana and a Fourth Amendment case in Montana.

They are expected to issue orders on Monday, October 20, following their private conference on Friday, but are not expected to summarize their positions until Monday, November 3.

While other federal judges—district, bankruptcy, and appellate courts—will also continue working,only essential staff will be joining them, the Administrative Office of the US Courts (OATC) announced. The furloughs of other court workers could delay the processing of cases.
