The U.S. Supreme Court will be closed Dec. 5 for the National Day of Mourning for former President George H.W. Bush.

The court was to hear its last argument of the year, Gamble v. United States, on that day. It’s been rescheduled for Dec. 6 at 10 a.m.

The high court almost never closes when business is scheduled. It remained open during the 16-day federal government shutdown in 2013.

But the building was ordered closed in 2007 following the death of former President Gerald R. Ford.

‘Essence of Decency’

Bush, who died on Dec. 1 at 94, made two Supreme Court appointments, including David Souter, who is now retired, and Clarence Thomas, the court’s longest serving current justice.

“The president was a gentleman who showed me great kindness, and for as long as memory serves I’ll think back on him kindly and gratefully in return,” Souter said in a statement.

Thomas said the former chief executive and first lady Barbara Bush “were the essence of decency and kindness then and throughout the years.”
