The 9th Cir. has announced:
We have limited staff in the courthouse due to the current public health crisis. We are asking that you email inquiries instead of calling the court during this time. Court staff will respond to you as soon as possible, likely within a few hours. The email address is: questions@ca9.uscourts.gov. Please include your case number and a telephone number in case court staff needs to reach you.
Also:
The oral argument hearings scheduled for March 30 to April 3 in Seattle have been moved to Pasadena. There will be no oral argument hearings in Seattle that week.
