The U.S. Fifth Circuit has this announcement on its home page:
In light of the many developments over the last few days concerning the COVID-19 virus, the Court has cancelled in-person oral arguments scheduled for March 30 – April 2, 2020. Clerk’s Office staff will personally contact counsel and discuss individual cases, including possible telephonic argument for cases the panels determine require argument. The public is advised that if telephonic argument is held, the court will promptly post the audio files on this website.
The John Minor Wisdom Building is closed to the public, beginning Monday, March 16, continuing until further notice. The Clerk’s Office will remain open, but the public will not be permitted to access the Clerk’s Office second floor reception area. If a paper filing is required, a clerk employee will accept delivery at the ground floor entrance to the Hebert Building. We will advise the public of any changes to current rules regarding the filling of paper copies of pleadings.
