The 9th U.S. Circuit Court of Appeals in San Francisco will offer live audio streaming  of all oral arguments beginning today, it announced last week. You can listen to the proceedings online by visiting the court’s website and clicking on links listed under “Live Oral Arguments.”

Audio streaming begins today with oral arguments from the federal courthouse in Pasadena, Calif. It will also be available for future cases at the courthouses in San Francisco, Seattle and Portland. The calendar of upcoming arguments is posted on the court’s site.

Last month, the 9th Circuit began offering live video streaming of selected oral arguments. It has provided access to recorded audio of oral arguments since 2003 and recorded video of en banc panels and selected three-judge panels since 2010. The court’s recorded audio and video is available here.

Here in Massachusetts where I am based, the Supreme Judicial Court has been webcasting its oral arguments since 2005.
